The April 8 Total Solar Eclipse: Through the Eyes of NASA
NASA/Keegan Barber
On April 8, 2024, the Moon’s shadow swept across North America, treating millions to a breathtaking view of a total solar eclipse. As the Moon passed in front of the Sun, it revealed the Sun’s wispy white outer atmosphere — the corona.
This composite image of multiple exposures shows the progression of a total solar eclipse in Dallas on April 8, 2024. NASA/Keegan BarberPictures of total solar eclipses are beautiful — they capture a moment happening so far away, yet feels so close at the same time. But being there in person, you experience it in 3D. The eclipse doesn’t just appear in the sky. You feel it all around you. The light slowly dims, then suddenly engulfs you in darkness from every angle, while the Sun’s corona emerges in the sky.
Although you know totality is coming, its arrival can still be overwhelming. For some people, their hearts race or their eyes well up with tears. You try to absorb everything you can in those minutes: from the corona, to the planets peeking out around the eclipse, to the temperature drop, to cheers of excitement from the community around you, even changes in animal behaviors.

For years, people have reported how animals behave differently during eclipses. Birds may return to their nests, thinking it’s nighttime, or nocturnal animals begin to wake up. A NASA-funded project called Eclipse Soundscapes collected data from participants across the path who recorded the reactions of wildlife before, during, and after this celestial event.

Total solar eclipses are a great reminder that humans are animals — we, too, feel the strangeness that causes other animals to have unusual behaviors. When experiencing the sudden change to darkness, and the sudden restoration of light, it can feel eerie and special. The world returns to normal around you, but those minutes of totality were anything but.

On April 8, millions of people gathered across the path of totality, including at 14 NASA “SunSpot” locations where attendees could speak to NASA experts and engage in educational activities. At many locations, visitors set up blankets, lawn chairs, and picnics as they prepared to watch the Sun turn into a crescent until its bright face completely disappeared.

Viewers could also see bright pink prominences flowing out from the Sun. Prominences are unstable clouds of plasma suspended above the Sun by strong magnetic forces. The prominences spotted during the eclipse were many times larger than Earth itself. It’s rare to be able to spot prominences from the ground unaided by a telescope, so seeing these prominences with just your eyes was a unique opportunity for those on the ground.

NASA/Keegan BarberWhile we were watching the eclipse from the ground, a NASA spacecraft was watching from above. NASA’s Solar Dynamics Observatory (SDO) captured this image of the Sun a few minutes before totality in Dallas at 1:37 p.m. CDT (18:37 UTC). From SDO’s position in space, the Sun was completely visible, while for people on Earth, the Sun was blocked by the Moon. The prominences seen in this image were what viewers on the ground were able to see with the naked eye.

NASA/SDOAstronauts on the International Space Station also had an exclusive view of the eclipse from 261 miles above Earth. Due to their place in space, they could see the Moon’s shadow travel across Earth. While those of us on Earth watched the Moon pass in front of the Sun, astronauts on the International Space Station watched its shadow pass over Earth.

45 Years Ago: Space Shuttle Enterprise Arrives at NASA’s Kennedy Space Center
Enterprise, the first space shuttle orbiter that NASA built, arrived at NASA’s Kennedy Space Center (KSC) in Florida on April 10, 1979. Although not space worthy, as a pathfinder Enterprise carried out tasks critical to ensuring the success of the space shuttle program. During its four-month stay at KSC, Enterprise validated procedures for the assembly of the space shuttle stack and interfaces at the launch pad. The tests proved valuable in preparing the shuttle for its first orbital mission. Earlier, Enterprise proved the flight worthiness of the shuttle during atmospheric tests and certified the vehicle’s structure to handle launch loads. Enterprise played small supporting roles in the Challenger and Columbia accident investigations. After a lengthy stay in storage, a fully restored Enterprise went on public display, first near Washington, D.C., and then in New York where it currently resides.

Enterprise’s story began on Jan. 5, 1972, when President Richard M. Nixon directed NASA to build the reusable space shuttle, formally called the Space Transportation System (STS), stating that “it would revolutionize transportation into near space.” NASA Administrator James C. Fletcher hailed the President’s decision as “an historic step in the nation’s space program,” adding that it would change what humans can accomplish in space. After Congress authorized the funds, on July 26 NASA awarded the contract to the North American Rockwell Corporation of Downey, California, to begin construction of the first vehicles. Manufacture of the first components of Orbital Vehicle-101 (OV-101) at Rockwell’s Downey plant began on June 4, 1974.

NASA originally chose the name Constitution for OV-101, the first space shuttle vehicle designed not to fly in space but for ground and atmospheric tests. However, a determined write-in campaign by fans of the science fiction TV series “Star Trek” convinced NASA to rename this first vehicle Enterprise, after the fictional starship made famous by the show. When the orbiter made its public rollout at Rockwell’s Palmdale, California, facility, on Sept. 17, 1976, it bore the name Enterprise. Several “Star Trek” cast members as well as the show’s creator attended the event, accompanied by NASA Administrator Fletcher and the four astronauts assigned to conduct the Approach and Landing Tests (ALT) with Enterprise– Fred W. Haise, C. Gordon Fullerton, Joe H. Engle, and Richard H. Truly.

Right: At NASA’s Marshall Space Flight Center in Huntsville, Alabama, for vibration tests, a shuttle orbiter joins an External Tank and twin Solid Rocket Boosters for the first time.
In January 1977, workers trucked Enterprise 36 miles overland from Palmdale to NASA’s Dryden, now Armstrong, Flight Research Center at Edwards Air Force Base (AFB) in California, for the ALT program, a series of increasingly complex flights to evaluate the shuttle’s air worthiness. At Dryden, workers placed Enterprise on the back of the Shuttle Carrier Aircraft (SCA), a modified Boeing 747. The duo began taxi runs in February, followed by the first captive inactive flight later that month. The first captive active flight with a crew aboard the orbiter took place in June, and Enterprise made its first independent flight on Aug. 12 with Haise and Fullerton at the controls. Four additional approach and landing flights completed the ALT program by October. In March 1978, Enterprise began its first cross-country trip. Riding atop the SCA, Enterprise left Edwards, and after a weekend stopover at Houston’s Ellington AFB, arrived at the Redstone Arsenal’s airfield in Huntsville, Alabama. Workers trucked Enterprise to the adjacent NASA Marshall Space Flight Center where engineers for the first time mated it with an External Tank (ET) and inert Solid Rocket Boosters (SRB) in the Dynamic Structural Test Facility. For the next year, engineers conducted a series of vibration tests on the combined vehicle, simulating conditions expected during an actual launch.

Following the year-long series of tests at Marshall, on April 10, 1979, NASA ferried Enterprise atop its SCA to KSC. Its sister ship Columbia, the first shuttle destined for orbital flight, had arrived there just two weeks earlier. The SCA/Enterprise vehicle remained on display at the Shuttle Landing Facility (SLF) for five days to give more than 75,000 KSC employees, their families, and the general public a chance to view the new reusable spacecraft. Workers at the SLF then removed the orbiter from the back of the SCA in the Mate-Demate Device, and towed it into High Bay 3 of the Vehicle Assembly Building (VAB) where on April 25 they completed attaching it to an ET and inert SRBs on a Mobile Launch Platform (MLP) repurposed from carrying Saturn rockets. These activities enabled verification of towing, assembly, and checkout procedures.

Rollout of Enterprise from the VAB to Launch Pad 39A occurred on May 1, and again KSC employees and their families came out to view the event. The assembled vehicle including the MLP weighed about 11 million pounds. Technicians drove the stack atop the Crawler Transporter at varying speeds to determine the optimum velocity to minimize vibration stress on the vehicle. The 3.5-mile rollout took about eight hours to complete. Once at the pad, engineers used Enterprise to conduct fit checks and to validate launch pad procedures. During the critical countdown demonstration test, workers filled the ET with super-cold liquid hydrogen and liquid oxygen. The significant discovery that ice built up at the top of the ET during this process led to the addition of the gaseous oxygen vent hood (familiarly known as the “beanie cap”) to the launch pad facility and a procedure to retract it just a few minutes before liftoff. This prevented the dangerous buildup of ice during the countdown and ranks as perhaps one of Enterprise’s greatest contributions as a test vehicle during its time at the launch pad.

On July 23, after three months of fit checks and testing, workers rolled Enterprise back from Launch Pad 39A to High Bay 1 in the VAB. The activities conducted at the pad proved instrumental in paving the way for its sister ship Columbia to make its first launch in 1981. John Bell, who managed the activities at JSC said of the test program, “Overall, it was a very successful venture and well worth it.” Launch Pad 39A Site Manager John J. “Tip” Talone added, “Having [Enterprise] out here really saved the program a lot of time in getting things ready for [Columbia].” In the VAB, workers removed Enterprise from its ET on July 25 and towed it to the SLF on Aug. 3 where it awaited the arrival of the SCA. The ferry flight back to Dryden took place between Aug. 10 and 16 making six stops along the way – Atlanta, St. Louis, Tulsa, Denver, Salt Lake City, and Vandenberg AFB in California. Up to 750,000 people came out to see the orbiter and SCA. Back at Dryden, workers demated Enterprise and on Oct. 30 trucked it back to the Palmdale plant where engineers removed computers and instruments to be refurbished and used in other orbiters then under construction. Previous plans to convert Enterprise into an orbital vehicle proved too costly and NASA abandoned the idea.

Middle right: Enterprise rolls back into the Vehicle Assembly Building. Right: Enterprise departs NASA’s Kennedy Space Center in Florida atop the Shuttle Carrier Aircraft.
Because Enterprise’s future remained uncertain, NASA returned it to Edwards on Sep. 6, 1981, for long-term storage. On July 4, 1982, NASA used it as a backdrop for President Ronald W. Reagan to welcome home the STS-4 crew. The following year, NASA sent Enterprise on a European tour, departing Dryden on May 13, 1983, with stops in the United Kingdom, Germany, Italy, and France for the annual Paris Air Show. Enterprise made a stop in Ottawa, Canada, on its return trip to Dryden, arriving there June 13. Workers once again placed it in temporary storage.

For its next public appearance, NASA ferried Enterprise to Mobile, Alabama, from there transported it by barge to New Orleans, and placed it on public display in the U.S. pavilion of the World’s Fair between April and November 1984. After the World’s Fair, NASA ferried Enterprise to Vandenberg AFB in California to conduct fit checks at the Space Launch Complex-6 (SLC-6), that NASA had planned to use for polar orbiting shuttle missions. NASA used Enterprise to conduct tests at SLC-6 similar to the 1979 tests at KSC’s Launch Complex 39. The tests at Vandenberg completed, NASA ferried Enterprise back to Dryden on May 24, 1985, but this time for only a very short-term storage.

On Sep. 20, 1985, NASA ferried Enterprise to KSC and placed it on temporary public display near the VAB, next to the Saturn V already displayed there. On Oct. 30, Enterprise “saw” its sister ship Challenger fly into space on the STS-61A mission. After two months on display at KSC, NASA flew Enterprise to Dulles International Airport outside Washington, D.C., arriving on Nov. 18. NASA officially retired Enterprise and transferred ownership to the Smithsonian Institution that had plans to build a large aircraft museum annex at the airport. The Smithsonian placed Enterprise in storage in a hangar, awaiting the completion of its new home. That turned into an 18-year wait.

Udvar-Hazy Center of the Smithsonian Institution’s National Air and Space Museum in Chantilly, Virginia. Right: Enterprise during arresting barrier testing at Dulles International Airport.
But even during that 18-year wait, NASA found practical use for the venerable Enterprise. In 1987, the agency studied how to handle an orbiter returning from space should it suffer a brake failure. To test the efficacy of an arresting barrier, workers slowly winched Enterprise into a landing barrier they had set up at Dulles to see if the vehicle suffered any damage. Later that same year, NASA used Enterprise to test various crew bailout procedures being developed in the wake of the Challenger accident. In 1990, experimenters used Enterprise’s cockpit windows to test mount an antenna for the Shuttle Amateur Radio Experiment, with no other orbiters available. Periodically, engineers removed parts from Enterprise to test for materials durability, and also evaluated the structural integrity of the vehicle including its payload bay doors and found it to be in sound condition even after years in storage. In April 2003, in the wake of the Columbia accident, investigators borrowed Enterprise’s left landing gear door and part of the port wing for foam impact tests. The tests provided solid evidence for the foam strike as the cause of the accident.

On Nov. 20, 2003, workers towed Enterprise from its storage facility into a newly completed display hangar at the Stephen F. Udvar-Hazy Center of the Smithsonian Institution’s National Air and Space Museum at Dulles in Chantilly, Virginia. Specialists spent eight months restoring the orbiter and the museum placed it on public display on Dec. 15, 2004.

Udvar-Hazy Center of the Smithsonian Institution’s National Air and Space Museum in Chantilly, Virginia. Right: Actor Leonard Nimoy greets Enterprise at John F. Kennedy International Airport in New York City.
In 2011, NASA retired the space shuttle fleet and donated the vehicles to various museums around the country. The Intrepid Sea, Air & Space Museum in New York City acquired Enterprise, and on Apr. 19, 2012, workers removed the orbiter from its display at the Hazy Center – replacing it with the orbiter Discovery – and placed it atop a SCA for the final time. Eight days later, after a short flight from Dulles and a flyaround of New York and several of its famous landmarks, Enterprise landed at John F. Kennedy International Airport. Actor Leonard Nimoy, who played Mr. Spock in the original “Star Trek” television series, and attended Enterprise’s first rollout in 1976, greeted the orbiter on the runway. Workers lifted the orbiter from the SCA and placed it on a barge. It eventually arrived at the Intrepid Museum on June 3 and went on public display July 19. Enterprise suffered minor damage during Superstorm Sandy in October 2012, but workers fully restored it.

Tech Today: Folding NASA Experience into an Origami Toolkit
3 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Though the art of origami is centuries old, until the late 20th century it was considered virtually impossible to make insects or other figures with many long, complex protrusions. That changed with the introduction of math-based origami design, which Lang helped pioneer. Today, he’s still drawn to the challenges presented by insects and other arthropods, and they are well-represented in the menagerie of his origami gallery.After uncovering the mathematical underpinnings of origami, Robert Lang left a 20-year engineering career, including over four years at NASA’s Jet Propulsion Laboratory in Southern California, to pursue his lifelong passion. However, while he was working at JPL, Lang picked up an important key to computational design, allowing him to turn paper into impossibly intricate 3D forms.
In the center’s Micro Devices Laboratory in the late 1980s and early ’90s, Lang worked on building an optical computer that uses light rather than electricity to carry out calculations. This work introduced him to the concept of nonlinear constrained optimization.
Lang explained that a simple nonlinear constrained optimization problem is like packing different-sized balls into a box. The constraint is that the balls can’t overlap, and the solutions are nonlinear because the balls can be any direction or distance from each other. The optimization is making the box as small as possible.
System design optimization for lasers and other components requires minimizing energy consumption, semiconductor materials, and other costs. In origami, optimization means creating the most extensive form possible using a single sheet of paper.
In the mid-1990s, he took his expertise gain at JPL and created an open-source software called TreeMaker, the first program available to design complex origami figures. Lang’s design software uses an equation to map the points that will become features like a head and limbs. It helps decide exactly how far apart any two points have to be, depending on their location in the final shape.
In 2001, he left his last engineering job to become a full-time origamist, and he remains one of the world’s leading figures at the intersection of math and paper folding. Lang’s work ranges from small paper sculptures to huge public art made from metal and other materials, which he co-creates with other artists.
Since Lang left NASA, the agency has called him back in to consult on a few projects that capitalized on his dual background in engineering and origami. One of those was the Starshade concept, a design for a baseball diamond-sized disk that would fold up tightly to fit in a rocket fairing and then unfurl in space. There, it would block the light from a given star so a space telescope could photograph its planets. Credit: NASAThe art of folding has even crept into space technology in recent years. Commercial companies now seek out Lang for his origami and engineering backgrounds to consult on folding hardware, including a collapsible radio antenna and Lawrence Livermore National Laboratory’s Eyeglass space telescope. He’s also returned to NASA to help figure out how to fold large objects for launch inside rocket fairings.
“The irony is that, when I was employed full-time at NASA, I was not working on origami, but after I left, I’ve been invited back a couple of times to work on origami-related projects,” he said.

Hubble Spots a Galaxy Hidden in a Dark Cloud

Hubble Spots a Galaxy Hidden in a Dark Cloud This Hubble image features the spiral galaxy IC 4633. ESA/Hubble & NASA, J. Dalcanton, Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURA; Acknowledgement: L. ShatzThe subject of this image taken with the NASA/ESA Hubble Space Telescope is the spiral galaxy IC 4633, located 100 million light-years away from us in the constellation Apus. IC 4633 is a galaxy rich in star-forming activity and also hosts an active galactic nucleus at its core. From our point of view, the galaxy is tilted mostly towards us, giving astronomers a fairly good view of its billions of stars.
However, we can’t fully appreciate the features of this galaxy — at least in visible light — because it’s partially concealed by a stretch of dark dust (lower-right third of the image). This dark nebula is part of the Chamaeleon star-forming region, itself located only around 500 light-years from us, in a nearby part of our Milky Way galaxy. The dark clouds in the Chamaeleon region occupy a large area of the southern sky, covering their namesake constellation but also encroaching on nearby constellations, like Apus. The cloud is well-studied for its treasury of young stars, particularly the cloud Cha I, which both Hubble and the NASA/ESA/CSA James Webb Space Telescope have imaged.
The cloud overlapping IC 4633 lies east of the well-known Cha I, II, and III, and is also known as MW9 and the South Celestial Serpent. Classified as an integrated flux nebula (IFN) — a cloud of gas and dust in the Milky Way galaxy that’s not near to any single star and is only faintly lit by the total light of all the galaxy’s stars — this vast, narrow trail of faint gas that snakes over the southern celestial pole is much more subdued looking than its neighbors. Hubble has no problem making out the South Celestial Serpent, though this image captures only a tiny part of it.

Altitude Chamber Gets Upgrade for Artemis II, Spacecraft Testing Begins
Before the Orion spacecraft is stacked atop NASA’s powerful SLS (Space Launch System) rocket ahead of the Artemis II mission, engineers will put it through a series of rigorous tests to ensure it is ready for lunar flight. In preparation for testing, teams at the agency’s Kennedy Space Center in Florida have made significant upgrades to the altitude chamber where testing will occur.
Several of the tests take place inside one of two altitude chambers in the high bay of the Neil A. Armstrong Operations and Checkout (O&C) Building at Kennedy. These tests, which began on April 10, include checking out electromagnetic interference and electromagnetic compatibility, which demonstrate the capability of the spacecraft when subjected to internally and externally generated electromagnetic energy and verify that all systems perform as they would during the mission.
To prepare for the tests, the west altitude chamber was upgraded to test the spacecraft in a vacuum environment that simulates an altitude of up to 250,000 feet. These upgrades re-activated altitude chamber testing capabilities for the Orion spacecraft at Kennedy. Previous vacuum testing on the Orion spacecraft for Artemis I took place at NASA’s Glenn Research Center in Ohio. Teams also installed a 30-ton crane in the O&C to lift and lower the Orion crew and service module stack into the chamber, lift and lower the chamber’s lid, and move the spacecraft across the high bay.

This event marks the first time, since the Apollo testing, that a spacecraft designed for human exploration of space has entered the chamber for testing. After testing is complete, the spacecraft will return to the Final Assembly and Systems Testing, or FAST, cell in the O&C for further work. Later this summer, teams will lift Orion back into the altitude chamber to conduct a test that simulates as close as possible the conditions in the vacuum of deep space.
Originally used to test environmental and life support systems on the lunar and command modules during the Apollo Program, the interior of each altitude chamber measures 33 feet in diameter and 44 feet high and was designed to simulate the vacuum equivalent of up to 200,000 feet in a deep space environment. Both chambers were rated for astronaut crews to operate flight systems during tests.

New LED lights replaced the previous lighting system, and equipment from the Apollo days was removed. A pressure control system was added to the chamber that provides precise control of pressure levels. Two new pumps remove the air from the chamber to create a vacuum. New guardrails and service platforms replaced the older platforms inside the chamber.
A new control room overlooks the upgraded chamber. It contains several workstations and communication equipment. The chamber control and monitoring system was upgraded to handle operation of all the remotely controlled hardware and subsystems that make up the vacuum testing capability.
“It was an amazing opportunity to lead a diverse and exceptional team to re-activate a capability for testing the NASA’s next generation spacecraft that will carry humans back to the Moon,” said Marie Reed, West Altitude Chamber Reactivation Project Manager. “The team of more than 70 aerospace professionals, included individuals from NASA, Lockheed Martin, Artic Slope Research Corps, Jacobs Engineering, and every discipline area imaginable. This project required long hours of dedication and exceptional coordination to enable the successful turn-around and activation in time for this Artemis II spacecraft testing.”

Media Get Close-Up of NASA’s Jupiter-Bound Europa Clipper
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Members of the media visited a clean room at JPL April 11 to get a close-up look at NASA’s Europa Clipper spacecraft and interview members of the mission team. The spacecraft is expected to launch in October 2024 on a six-year journey to the Jupiter system, where it will study the ice-encased moon Europa.NASA/JPL-CaltechExcitement is mounting as the largest spacecraft NASA has ever built for a planetary mission gets readied for an October launch.
Engineers at NASA’s Jet Propulsion Laboratory in Southern California are running final tests and preparing the agency’s Europa Clipper spacecraft for the next leg of its journey: launching from NASA’s Kennedy Space Center in Florida. Europa Clipper, which will orbit Jupiter and focus on the planet’s ice-encased moon Europa, is expected to leave JPL later this spring. Its launch period opens on Oct. 10.
Members of the media put on “bunny suits” — outfits to protect the massive spacecraft from contamination — to see Europa Clipper up close in JPL’s historic Spacecraft Assembly Facility on Thursday, April 11. Project Manager Jordan Evans, Launch-to-Mars Mission Manager Tracy Drain, Project Staff Scientist Samuel Howell, and Assembly, Test, and Launch Operations Cable Harness Engineer Luis Aguila were on the clean room floor, while Deputy Project Manager Tim Larson, and Mission Designer Ricardo Restrepo were in the gallery above to explain the mission and its goals.
The viewing gallery above High Bay 1 in JPL’s historic Spacecraft Assembly Facility provided members of the media with a vantage point to observe the clean room where Europa Clipper was put together.NASA/JPL-Caltech Europa Clipper Science Communications Lead Cynthia Phillips explains the science of the mission to members of the media in von Kármán Auditorium at the agency’s Jet Propulsion Laboratory on April 11. A cutaway model showing the moon’s layers can be seen behind Phillips.NASA/JPL-CaltechPlanning of the mission began in 2013, and Europa Clipper was officially confirmed by NASA as a mission in 2019. The trip to Jupiter is expected to take about six years, with flybys of Mars and Earth. Reaching the gas giant in 2030, the spacecraft will orbit Jupiter while flying by Europa dozens of times, dipping as close as 16 miles (25 kilometers) from the moon’s surface to gather data with its powerful suite of science instruments. The information will help scientists learn about the ocean beneath the moon’s icy shell, map Europa’s surface composition and geology, and hunt for any potential plumes of water vapor that may be venting from the crust.
“After over a decade of hard work and problem-solving, we’re so proud to show the nearly complete Europa Clipper spacecraft to the world,” said Evans. “As critical components came in from institutions across the globe, it’s been exciting to see parts become a greater whole. We can’t wait to get this spacecraft to the Jupiter system.”
At the event, a cutaway model showing the moon’s layers and a globe of the moon helped journalists learn why Europa is such an interesting object of study. On hand with the details were Project Staff Scientist and Assistant Science Systems Engineer Kate Craft from the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland, and, from JPL, Project Scientist Robert Pappalardo, Deputy Project Scientist Bonnie Buratti, and Science Communications Lead Cynthia Phillips.
Beyond Earth, Europa is considered one of the most promising potentially habitable environments in our solar system. While Europa Clipper is not a life-detection mission, its primary science goal is to determine whether there are places below the moon’s icy surface that could support life.
When the main part of the spacecraft arrives at Kennedy Space Center in a few months, engineers will finish preparing Europa Clipper for launch on a SpaceX Falcon Heavy rocket, attaching its giant solar arrays and carefully tucking the spacecraft inside the capsule that rides on top of the rocket. Then Europa Clipper will be ready to begin its space odyssey.
More About the MissionEuropa Clipper’s three main science objectives are to determine the thickness of the moon’s icy shell and its surface interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.
Managed by Caltech in Pasadena, California, JPL leads the development of the Europa Clipper mission in partnership with the Johns Hopkins Applied Physics Laboratory (APL) for NASA’s Science Mission Directorate in Washington. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center in Huntsville, Alabama, executes program management of the Europa Clipper mission.

NASA’s PACE Data on Ocean, Atmosphere, Climate Now Available
4 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s PACE satellite’s Ocean Color Instrument (OCI) detects light across a hyperspectral range, which gives scientists new information to differentiate communities of phytoplankton – a unique ability of NASA’s newest Earth-observing satellite. This first image released from OCI identifies two different communities of these microscopic marine organisms in the ocean off the coast of South Africa on Feb. 28, 2024. The central panel of this image shows Synechococcus in pink and picoeukaryotes in green. The left panel of this image shows a natural color view of the ocean, and the right panel displays the concentration of chlorophyll-a, a photosynthetic pigment used to identify the presence of phytoplankton.Credit: NASANASA is now publicly distributing science-quality data from its newest Earth-observing satellite, providing first-of-their-kind measurements of ocean health, air quality, and the effects of a changing climate.
The Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) satellite was launched on Feb. 8, and has been put through several weeks of in-orbit testing of the spacecraft and instruments to ensure proper functioning and data quality. The mission is gathering data that the public now can access at https://pace.oceansciences.org/access_pace_data.htm.
PACE data will allow researchers to study microscopic life in the ocean and particles in the air, advancing the understanding of issues including fisheries health, harmful algal blooms, air pollution, and wildfire smoke. With PACE, scientists also can investigate how the ocean and atmosphere interact with each other and are affected by a changing climate.
“These stunning images are furthering NASA’s commitment to protect our home planet,” said NASA Administrator Bill Nelson. “PACE’s observations will give us a better understanding of how our oceans and waterways, and the tiny organisms that call them home, impact Earth. From coastal communities to fisheries, NASA is gathering critical climate data for all people.”
“First light from the PACE mission is a major milestone in our ongoing efforts to better understand our changing planet. Earth is a water planet, and yet we know more about the surface of the moon than we do our own oceans. PACE is one of several key missions – including SWOT and our upcoming NISAR mission – that are opening a new age of Earth science,” said Karen St. Germain, NASA Earth Science Division director.
PACE’s OCI instrument also collects data that can be used to study atmospheric conditions. The top three panels of this OCI image depicting dust from Northern Africa carried into the Mediterranean Sea, show data that scientists have been able to collect in the past using satellite instruments – true color images, aerosol optical depth, and the UV aerosol index. The bottom two images visualize novel pieces of data that will help scientists create more accurate climate models. Single-Scattering Albedo (SSA) tells the fraction of light scattered or absorbed, which will be used to improve climate models. Aerosol Layer Height tells how low to the ground or high in the atmosphere aerosols are, which aids in understanding air quality.Credit: NASA/UMBCThe satellite’s Ocean Color Instrument, which was built and managed by NASA’s Goddard Space Flight Center in Greenbelt, Maryland, observes the ocean, land, and atmosphere across a spectrum of ultraviolet, visible, and near infrared light. While previous ocean color satellites could only detect a handful of wavelengths, PACE is detecting more than 200 wavelengths. With this extensive spectral range, scientists can identify specific communities of phytoplankton. Different species play different roles in the ecosystem and carbon cycle — most are benign, but some are harmful to human health — so distinguishing phytoplankton communities is a key mission of the satellite.
PACE’s two multi-angle polarimeters, HARP2 and SPEXone, measure polarized light that has reflected off clouds and tiny particles in the atmosphere. These particles, known as aerosols, can range from dust to smoke to sea spray and more. The two polarimeters are complementary in their capabilities. SPEXone, built at the Netherlands Institute for Space Research (SRON) and Airbus Netherlands B.V., will view Earth in hyperspectral resolution – detecting all the colors of the rainbow – at five different viewing angles. HARP2, built at the University of Maryland, Baltimore County (UMBC), will observe four wavelengths of light, with 60 different viewing angles.
Early data from the SPEXone polarimeter instrument aboard PACE show aerosols in a diagonal swath over Japan on Mar. 16, 2024, and Ethiopia on Mar. 6, 2024. In the top two panels, lighter colors represent a higher fraction of polarized light. In the bottom panels, SPEXone data has been used to differentiate between fine aerosols, like smoke, and coarse aerosols, like dust and sea spray. SPEXone data can also measure how much aerosols are absorbing light from the Sun. Above Ethiopia, the data show mostly fine particles absorbing sunlight, which is typical for smoke from biomass burning. In Japan, there are also fine aerosols, but without the same absorption. This indicates urban pollution from Tokyo, blown toward the ocean and mixed with sea salt. The SPEXone polarization observations are displayed on a background true color image from another of PACE’s instruments, OCI.Credit: SRONWith these data, scientists will be able to measure cloud properties — which are important for understanding climate — and monitor, analyze, and identify atmospheric aerosols to better inform the public about air quality. Scientists will also be able to learn how aerosols interact with clouds and influence cloud formation, which is essential to creating accurate climate models.
Early images from PACE’s HARP2 polarimeter captured data on clouds over the west coast of South America on Mar. 11, 2024. The polarimetry data can be used to determine information about the cloud droplets that make up the cloudbow – a rainbow produced by sunlight reflected by cloud droplets instead of rain droplets. Scientists can learn how the clouds respond to man-made pollution and other aerosols and can measure the size of the cloud droplets with this polarimetry data.Credit: UMBC“We’ve been dreaming of PACE-like imagery for over two decades. It’s surreal to finally see the real thing,” said Jeremy Werdell, PACE project scientist at NASA Goddard. “The data from all three instruments are of such high quality that we can start distributing it publicly two months from launch, and I’m proud of our team for making that happen. These data will not only positively impact our everyday lives by informing on air quality and the health of aquatic ecosystems, but also change how we view our home planet over time.”
The PACE mission is managed by NASA Goddard, which also built and tested the spacecraft and the ocean color instrument. The Hyper-Angular Rainbow Polarimeter #2 (HARP2) was designed and built by the University of Maryland, Baltimore County, and the Spectro-polarimeter for Planetary Exploration (SPEXone) was developed and built by a Dutch consortium led by Netherlands Institute for Space Research, Airbus Defence, and Space Netherlands.

NASA’s SERT II: ‘A Genuine Space Success Story’
5 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) An illustration of the SERT II spacecraft, which was comprised of the Agena upper stage, the experimental thrusters and associated equipment, and two large solar arrays.Credit: NASA“A genuine space success story,” is how Experiments Manager William Kerslake described NASA’s second Space Electric Rocket Test (SERT II), the first long-duration operation of ion thrusters in space. SERT II provided researchers with data for years beyond its expected lifetime and was a rare example of an entire mission – including the launch, propulsion system, spacecraft, and control center – being handled by one organization: NASA’s Lewis Research Center in Cleveland (today, NASA Glenn).
The concept of electric propulsion thrusters dates back to the early 20th century, but because they must operate in a vacuum, there was no practical application for these systems until the space program decades later. In the late 1950s, researchers at NASA Lewis began investigating types of electric propulsion and analyzing missions that could use these systems. They produce low amounts of thrust by creating and accelerating small particles at high velocities, and over time, can accelerate spacecraft at very high rates of speed. Their ability to operate continuously for years at a time with little propellant makes them ideal for long-duration missions or keeping satellites in orbit.
This work was expanded in the early 1960s with the creation of Lewis’ Electromagnetic Propulsion Division and the construction of large vacuum facilities, including the Electric Propulsion and Power Laboratory (EPPL). Lewis engineer Harold Kaufman’s electron bombardment ion engine, which used liquid mercury as its propellant, was the most promising option. While Kaufman’s thruster was undergoing extensive testing in the EPPL tanks, Lewis engineers began developing a spacecraft to test the thruster. During the 50-minute suborbital SERT I flight on July 20, 1964, the Kaufman thruster became the first ion engine to operate in space.
In early 1968, the experimental portion of SERT II underwent six months of testing in Tank 5 at NASA Lewis Research Center’s (now, NASA Glenn’s) Electric Propulsion and Power Laboratory in conditions that simulated the temperatures and pressures it would encounter in space. The two thrusters can be seen in this photograph.Credit: NASA/ Paul RiedelLewis continued improving the thruster system, and in August 1966 received approval for SERT II. Researchers wanted to verify the thrusters could operate for longer durations in space, determine their effect on other spacecraft systems, and measure the degradation of solar arrays over time.
The center began simultaneous development of the SERT II ion thruster system and the spacecraft that would place it into orbit: a Thorad-Agena rocket. SERT II had two 15-centimeter diameter electron bombardment thrusters affixed to the back end and a 5-by-40 foot solar array, the largest ever flown by NASA at that time, at the other end.
After a series of tests in the EPPL, SERT II blasted off on February 3, 1970. Project Manager Raymond Rulis called the launch “one of the smoothest operations I’ve seen.” SERT II was placed into a circular polar orbit that provided its solar arrays with the continuous sunlight required to power its thrusters and electronic systems.
A Thorad-Agena rocket lifts off from Vandenberg Air Force Base on February 3, 1970, with the SERT II spacecraft. NASA Lewis Research Center (now, NASA Glenn) managed the Agena Program between 1962 and 1970, with SERT II being the last of the center’s 28 successful launches.Credit: NASAOn February 14, 1970, Lewis engineers activated the first thruster, beginning its six-month operational test. Three weeks later, operators shut the thruster down just before the vehicle passed through the path of a solar eclipse. It was restarted without issue afterwards and continued operation as the spacecraft encountered the eclipse a second time later that day.
The thruster operated successfully for five months until an electrical short in the grid caused it to fail on July 22, 1970. Two days later, the second thruster was activated. It operated smoothly for three-and-a-half months until a similar short occurred in mid-October. Though the SERT II thrusters failed to meet their six-month objectives, they did operate for extended periods, confirming data obtained in Lewis’ vacuum tanks.
The mission continued when Lewis engineers reactivated SERT II in 1973 to demonstrate cathode restarting, and the following year, they resolved an electrical short in one of the thrusters. During periods of intermittent sunlight, operators demonstrated restarting the thruster with less than an hour of power available. SERT II’s return to an orbit in continuous sunlight in 1979 provided Lewis researchers the opportunity to conduct over 500 restarts. They operated the thruster for 18,000 hours before the propellant ran out in the spring of 1981.
William Kerslake (seen in this 1981 photograph) and Louis Ignaczak managed the SERT II operations from a specially designed control center in NASA’s Lewis Research Center’s (now, NASA Glenn’s) 10-by 10-Foot Supersonic Wind Tunnel building. The control center allowed engineers to monitor the mission and send commands to the spacecraft through NASA’s satellite communication system. Credit: NASA/Daniel LaietyOver eleven years, SERT II provided data on hundreds of thruster restarts, restarts after shutdowns as long as 18 months, ion beam neutralization of one thruster by the other, and discovery of a new plasma thrust mode. SERT II also verified that thruster operation had no harmful impact on spacecraft and solar arrays.
Still, SERT II continued to be an asset to NASA researchers. In the late 1980s, Lewis engineers realized that an auxiliary experiment on SERT II that analyzed the effect of micrometeoroids on solar mirrors could be beneficial to research on solar dynamic systems to power space stations. During six months in sunlight in 1990, the Lewis team determined that after 20 years in orbit, there was no degradation of the solar mirror’s optical properties.
Many technological components of the SERT II thruster system were incorporated into subsequent generations of ion thrusters. By the time the mission was terminated, Lewis was already ground testing thrusters twice the size of those on SERT II. The center has continued to lead NASA’s electric propulsion efforts, developing an array of technologies, including the NEXT-C thrusters that powered the Deep Space 1 and Dawn spacecraft. In support of the agency’s Artemis missions, NASA Glenn recently tested the thrusters that will power Gateway, NASA’s future lunar space station.

Among our initiatives is the resurgence of K-12 programs, where we engage with schools in our region. My focus primarily involves collaborating with high schools and middle schools, reaching out to instill the NASA way of thinking and inspiring students to see the impact of a STEM education. We are dedicated to fostering a mindset that emphasizes working at NASA in science, technology, engineering, and math roles beyond being an astronaut.
Additionally, I serve as the liaison for diversity, equity, inclusion, and accessibility between NASA’s Office of Diversity and Equal Opportunity and OSTEM. Our goal is to ensure that our processes embrace everyone, irrespective of their background or identity. I act as the bridge, pulling together diverse perspectives and information to create a more inclusive work environment.
I’m also actively involved in two solicitations — one for Minority University Research and Education Project (MUREP) OCEAN related projects, and another focused on Data Science Equity, Access and Priority (DEAP). We collaborate with faculty to award research grants, reaching out to individuals who might not typically hear about these opportunities but possess the skills and potential to excel.
What path led you to this role?
My journey with NASA started in 2002, and I arrived at Goddard in 2020 after being part of the Office of STEM Engagement at headquarters in Washington. Embarking on my career in the government at the age of 16, I faced a unique and early entry into the professional world. Despite my youth, I embraced the opportunities presented to me and took on a series of diverse assignments within the government sector. This journey was marked by a steadfast commitment to the philosophy of “growing where I was planted.”
In practical terms, this philosophy implies a dedication to making the most of the current circumstances and roles, regardless of their initial nature or perceived limitations. Instead of constantly seeking new environments, I focused on developing my skills, gaining valuable experiences, and contributing meaningfully to each position I held. This approach allowed me to extract valuable lessons and skills from every assignment, fostering personal and professional growth in unexpected ways.
The belief in “growing where I was planted” also speaks to resilience and adaptability. Rather than succumbing to challenges or setbacks, I viewed them as opportunities to learn and adapt. This mindset not only helped me navigate the complexities of working in the government but also positioned me to thrive in a variety of roles over the years.
As a result of this philosophy, I built a foundation of skills, knowledge, and adaptability that eventually led me to my current role at Goddard. Each assignment, whether seemingly small or significant, played a crucial role in shaping my career trajectory and preparing me for the challenges and responsibilities I now undertake in supporting programs and initiatives at Goddard.
What’s the most exciting or interesting part of working at NASA?
Being in a position that involves interactions with celebrities has been one of the most enjoyable aspects of my work. It provides a unique glimpse into the individuals who contribute to TV programs, movies, and media that showcase NASA’s endeavors towards our society’s forward progression. During my early days, I had the fascinating role of booking meetings that involved notable figures, and although the interaction was swift, the experience of seeing them in person was truly thrilling.
While working in the administrator’s office at headquarters, I had the privilege of witnessing the arrival of news reporters, city mayors, congressmen and women, and astronauts who came to meet with the administrator. Sitting in anticipation, I played a behind-the-scenes role, having foreknowledge of their visits and assisting in the planning process. Although my involvement was indirect, the opportunity to be in proximity to these space explorers and others and to play a part in coordinating their interactions was both rewarding and awe-inspiring.

However, one standout memory involves meeting Nichelle Nichols, who played Uhura on “Star Trek,” at the final space shuttle launch. STS-135, the last flight of the orbiter Atlantis, lifted off from Launch Pad 39A at NASA’s Kennedy Space Center in Florida on July 8, 2011. I will always be grateful to Ms. Nichols for the real-life role she played at NASA, which was to recruit minority and female astronauts and personnel for the agency’s Space Shuttle Program.
The sheer thought of being in the company of someone of her stature and witnessing firsthand the intersection of entertainment and NASA’s mission left a lasting impression. These encounters not only added a layer of excitement to my role but also reinforced the significance of the work we do at NASA, captivating the attention of influential figures who contribute to sharing our stories with the world.

Student Launch provides relevant, cost-effective research and development of rocket propulsion systems and reflects the goals of NASA’s Artemis campaign, which seeks to put the first woman and first person of color on the Moon.
Each year, the payload component changes to reflect current NASA missions. This year’s payload challenge is inspired by the Artemis missions.
Students will design a SAIL (STEMnaut Atmosphere Independent Lander) payload. It must deploy mid-air, safely return to the ground without using a parachute, and be reusable to launch the same day without repairs or modifications. The payload will contain a crew of STEMnauts, four non-living objects representing astronauts. Students will choose metrics to determine the endurance of the lander, considering acceptable descent and landing parameters.
Middle and high school teams can choose to attempt the lander payload or develop their own science or engineering experiment.
Eligible teams compete for prizes and awards and are scored in nearly a dozen categories including safety, vehicle design, social media presence, and science, technology, engineering, and math (STEM) engagement. Teams can also win the Altitude Award in each division based on how close they get to the altitude they projected their rockets would reach months in advance to launch day.
Marshall’s Office of STEM Engagement hosts Student Launch to encourage students to pursue careers in STEM through real-world experiences. Student Launch is a part of the agency’s Artemis Student Challenges – a variety of activities exposing students to the knowledge and technology required to achieve the goals of the Artemis missions.
In addition to the NASA Office of STEM Engagement’s Next Gen STEM project, NASA Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space and Bastion Technologies provide funding and leadership for the competition.

Michoud Site Recovery Team Receives NASA’s Silver Group Achievement AwardBy Heather Keller
The High Voltage Hurricane Ida Site Recovery Team at NASA’s Michoud Assembly Facility was awarded the agency’s Silver Group Achievement Award on March 18. The team of seven was recognized for “exemplary employee dedication and perseverance ensuring the safety of site, SLS (Space Launch System) hardware, and personnel” onsite post landfall of the category 4 storm.
Hurricane Ida made landfall in southeast Louisiana on Aug. 29, 2021, causing catastrophic failure of high voltage infrastructure and leaving most of the city of New Orleans without power for several weeks. Michoud received major damage from the storm’s 112 mph wind gusts and sustained winds of 80 mph. Immediately after landfall, the Michoud High Voltage Team methodically and safely energized the 6 MW emergency generator while procedurally transferring power to the facility’s east and west master substations. The transfer provided critical power to the rocket factory’s final assembly area while coordinating with the SLS Program and Boeing.

The team also provided power for lighting, allowing the Boeing teams to conduct critical inspections of flight hardware for damages.
The team also set up and provided emergency generator power for critical site infrastructure, such as the Coast Guard Exchange (CGX), which provided fuel for response and recovery personnel and other necessary supplies.
The High Voltage Team collaborated with Entergy New Orleans to determine a timeline for Michoud to accept line voltage from the site’s generating station and was successful in accepting power five days post-landfall. They systematically worked to safely bring additional loads online as prioritized and requested by Boeing and the SLS Program with more than 35 buildings receiving power approximately eight days post hurricane and allow site opening for tenant access.

Dr. Sterry: Be Aware of Increase in Alcohol Abuse Rates Post COVIDDear Marshall family,
April is Alcohol Awareness Month, and recent data indicate the rates of alcohol abuse and deaths resulting from it have risen dramatically over the past few years.
Very early during the COVID-19 pandemic it became apparent that sales of alcohol were increasing, and so it has been expected that the negative impacts related to this issue would increase as well. But I don’t think anyone anticipated just how much they would increase. I understand your first inclination might be to skip over this, but it’s a quick read, so please take a moment to consider the situation for the sake of your family, friends, and co-workers.
Data from 2020–2021, published by the Centers for Disease Control and Prevention, indicate that 178,000 people died in the U.S. from alcohol abuse and related health problems during that period. This represents a 29% increase from 2016–2017, when there were an estimated 138,000 deaths. Similarly disturbing, data published by the National Institute on Alcohol Abuse and Alcoholism indicate that rates of alcohol use disorder rose from 14.5 million adults in the U.S. in 2019 to 29.5 million in 2022.
Since a majority of adults in the U.S. drink alcoholic beverages on occasion, it is becoming even more important to be mindful of how to reduce the risks of negative impacts on our health, and on our lives, in general. The U.S. Department of Agriculture offers guidelines for alcohol consumption geared toward limiting those risks: no more than one standard drink per day for women, and no more than two standard drinks per day for men. While the difference in the numbers may seem unfair, they are based primarily upon body mass and metabolism rates.
What constitutes a “standard drink” depends upon what you’re drinking. For example, for beer, it is 12 fluid ounces, for wine, it is 5 fluid ounces, and for liquor, it is 1.5 fluid ounces. While being mindful of the number of drinks we’re consuming, it’s also important to keep in mind that even within any given category or type of drink, the percentage of alcohol can vary significantly from one product to another. For example, in Alabama, beer can contain up to 13.9% alcohol, and wine can contain up to 24%.
I have two requests of you today. First, please be mindful of how much you’re drinking, and be deliberate in reducing your risks, if needed. If you’d like to do a quick assessment of your drinking, an anonymous self-report test is available at https://auditscreen.org/check-your-drinking. Also, please consider sharing this information with any of your family members and friends that you think might be at risk for the health problems and other dangers associated with alcohol abuse.
If you’d like to get more information about alcohol abuse, and the dangers associated with it, a few good resources include:

NASA Achieves Milestone for Engines to Power Future Artemis MissionsNASA achieved a major milestone April 3 for production of new RS-25 engines to help power its Artemis campaign to the Moon and beyond with completion of a critical engine certification test series at NASA’s Stennis Space Center.
The 12-test series represents a key step for lead engines contractor Aerojet Rocketdyne, an L3Harris Technologies company, to build new RS-25 engines, using modern processes and manufacturing techniques, for NASA’s SLS (Space Launch System) rockets that will power future lunar missions, beginning with Artemis V.
NASA conducted a full-duration RS-25 hot fire April 3 on the Fred Haise Test Stand at the agency’s Stennis Space Center, achieving a major milestone for future Artemis flights of NASA’s SLS (Space Launch System) rocket. It marked the final test of a 12-test series to certify production of new RS-25 engines by lead contractor Aerojet Rocketdyne, an L3Harris Technologies company, to help power SLS on Artemis missions to the Moon and beyond, beginning with Artemis V.NASA/Danny Nowlin“The conclusion of the certification test series at NASA Stennis is just the beginning for the next generation of RS-25 engines that will help power human spaceflight for Artemis,” said Johnny Heflin, SLS liquid engines manager. “The newly produced engines on future SLS rockets will maintain the high reliability and safe flight operational legacy the RS-25 is known for while enabling more affordable high-performance engines for the next era of deep space exploration.”
Through Artemis, NASA will establish the foundation for long-term scientific exploration at the Moon; land the first woman, first person of color, and first international partner astronaut on the lunar surface; and prepare for human expeditions to Mars for the benefit of all.
Contributing to that effort, the NASA Stennis test team conducted a full-duration, 500-second hot fire to complete the 12-test series on developmental engine E0525, providing critical performance data for the final RS-25 design certification review. The April 3 hot fire completed a test series that began in October 2023.
RS-25 engines are evolved space shuttle main engines, upgraded with new components to produce the additional power needed to help launch NASA’s SLS rocket. The first four Artemis missions are using modified space shuttle main engines also tested at NASA Stennis. For each Artemis mission, four RS-25 engines, along with a pair of solid rocket boosters, power the SLS rocket, producing more than 8.8 million pounds of total combined thrust at liftoff.
“This was a critical test series, and credit goes to the entire test team for their dedication and unique skills that allowed us to meet the schedule and provide the needed performance data,” said Chip Ellis, project manager for RS-25 testing at NASA Stennis. “The tests conducted at NASA Stennis help ensure the safety of our astronauts and their future mission success. We are proud to be part of the Artemis mission.”
Crews transport RS-25 developmental engine E0525 to the Fred Haise Test Stand on Aug. 30, 2023, for the second and final certification test series.NASA/Danny NowlinThe E0525 developmental engine featured new key components – including a nozzle, hydraulic actuators, flex ducts, and turbopumps – that matched design features of those used during an initial certification test series completed at NASA Stennis last summer.
The two certification test series helped verify the new engine components meet all Artemis flight requirements moving forward. Aerojet Rocketdyne is using techniques such as 3D printing to produce new RS-25 engines more efficiently, while maintaining high performance and reliability. NASA has awarded the company contracts to provide 24 new engines, supporting SLS launches for Artemis V through Artemis IX.
“Successfully completing this rigorous test series is a testament to the outstanding work done by the team to design, implement and test this upgraded version of the RS-25 that reduces the cost by 30% from the space shuttle program,” said Mike Lauer, RS-25 program director at Aerojet Rocketdyne. “We tested the new RS-25 engines to the extreme limits of operation to ensure the engines can operate at a higher power level needed for SLS and complete the mission with margin.”
RS-25 Final Certification Test Series by the Numbers
All RS-25 engines are tested and proven flightworthy at NASA Stennis prior to use on Artemis missions. RS-25 tests at the center are conducted by a diverse team of operators from NASA, Aerojet Rocketdyne, and Syncom Space Services, prime contractor for site facilities and operations.
NASA’s Marshall Space Flight Center manages the SLS Program.
Agency Selects Companies to Advance Moon Mobility for Artemis MissionsNASA has selected Intuitive Machines, Lunar Outpost, and Venturi Astrolab to advance capabilities for a lunar terrain vehicle (LTV) that Artemis astronauts will use to travel around the lunar surface, conducting scientific research during the agency’s Artemis campaign at the Moon and preparing for human missions to Mars.
The awards leverage NASA’s expertise in developing and operating rovers to build commercial capabilities that support scientific discovery and long-term human exploration on the Moon. NASA intends to begin using the LTV for crewed operations during Artemis V.
An artist’s concept design of NASA’s lunar terrain vehicle.NASA“We look forward to the development of the Artemis generation lunar exploration vehicle to help us advance what we learn at the Moon,” said Vanessa Wyche, director of NASA’s Johnson Space Center. “This vehicle will greatly increase our astronauts’ ability to explore and conduct science on the lunar surface while also serving as a science platform between crewed missions.”
NASA will acquire the LTV as a service from industry. The indefinite-delivery/indefinite-quantity, milestone-based Lunar Terrain Vehicle Services contract with firm-fixed-price task orders has a combined maximum potential value of $4.6 billion for all awards.
Each provider will begin with a feasibility task order, which will be a year-long special study to develop a system that meets NASA’s requirements through the preliminary design maturity project phase. The agency will issue a subsequent request for task order proposal to eligible provider(s) for a demonstration mission to continue developing the LTV, deliver it to the surface of the Moon, and validate its performance and safety ahead of Artemis V. NASA anticipates making an award to only one provider for the demonstration. NASA will issue additional task orders to provide unpressurized rover capabilities for the agency’s moonwalking and scientific exploration needs through 2039.
The LTV will be able to handle the extreme conditions at the Moon’s South Pole and will feature advanced technologies for power management, autonomous driving, and state of the art communications and navigation systems. Crews will use the LTV to explore, transport scientific equipment, and collect samples of the lunar surface, much farther than they could on foot, enabling increased science returns.
Between Artemis missions, when crews are not on the Moon, the LTV will operate remotely to support NASA’s scientific objectives as needed. Outside those times, the provider will have the ability to use their LTV for commercial lunar surface activities unrelated to NASA missions.
“We will use the LTV to travel to locations we might not otherwise be able to reach on foot, increasing our ability to explore and make new scientific discoveries,” said Jacob Bleacher, chief exploration scientist in the Exploration Systems Development Mission Directorate at NASA Headquarters. “With the Artemis crewed missions, and during remote operations when there is not a crew on the surface, we are enabling science and discovery on the Moon year around.”
NASA provided technical requirements, capabilities, and safety standards needed for LTV development and operations, and the selected companies have agreed to meet the key agency requirements. The contract request for proposal required each provider to propose a solution to provide end-to-end services, including LTV development, delivery to the Moon, and execution of operations on the lunar surface.
Through Artemis, NASA will send astronauts – including the first woman, first person of color, and its first international partner astronaut – to explore the Moon for scientific discovery, technology evolution, economic benefits, and to build the foundation for crewed missions to Mars. Advanced rovers, along with the agency’s SLS (Space Launch System) rocket and Orion spacecraft, commercial human landing systems and next-generation spacesuits, and Gateway are NASA’s foundation for deep space exploration.
Hubble Peers at Pair of Closely Interacting GalaxiesAn image from the NASA/ESA Hubble Space Telescope features Arp 72, a very selective galaxy group that only includes two galaxies interacting due to gravity: NGC 5996 (the large spiral galaxy) and NGC 5994 (its smaller companion, in the lower left of the image).
This NASA/ESA Hubble Space Telescope image features Arp 72.ESA/Hubble & NASA, L. Galbany, J. Dalcanton, Dark Energy Survey/DOE/FNAL/DECam/CTIO/NOIRLab/NSF/AURABoth galaxies lie approximately 160 million light-years from Earth, and their cores are separated from each other by a distance of about 67,000 light-years. The distance between the galaxies at their closest points is even smaller, closer to 40,000 light-years.
While this might sound vast, in galactic separation terms it is quite close. For comparison, the distance between the Milky Way and its nearest independent galactic neighbor Andromeda is around 2.5 million light-years. Alternatively, the distance between the Milky Way and its largest and brightest satellite galaxy, the Large Magellanic Cloud (satellite galaxies orbit around another galaxy), is about 162,000 light-years.
Given this and the fact that NGC 5996 is comparable in size to the Milky Way, it is not surprising that NGC 5996 and NGC 5994 – separated by only about 40,000 light-years – are interacting with one another. In fact, the interaction likely distorted NGC 5996’s spiral shape. It also prompted the formation of the very long and faint tail of stars and gas curving away from NGC 5996, up to the top right of the image. This “tidal tail” is a common phenomenon that appears when galaxies closely interact and is visible in other Hubble images of interacting galaxies.
NASA, Japan Advance Space Cooperation, Sign Agreement for Lunar Rover
NASA Administrator Bill Nelson and Japan’s Minister of Education, Culture, Sports, Science and Technology (MEXT) Masahito Moriyama have signed an agreement to advance sustainable human exploration of the Moon.
Japan will design, develop, and operate a pressurized rover for crewed and uncrewed exploration on the Moon. NASA will provide the launch and delivery of the rover to the Moon as well as two opportunities for Japanese astronauts to travel to the lunar surface.
Today, President Biden and Prime Minister Kishida also announced, “a shared goal for a Japanese national to be the first non-American astronaut to land on the Moon on a future Artemis mission, assuming important benchmarks are achieved.”
The pressurized lunar rover is intended to enable astronauts to travel farther and work for longer periods on the lunar surface. The signing took place April 9 at NASA Headquarters in Washington. Along with Nelson and Moriyama, JAXA (Japan Aerospace Exploration Agency) President Hiroshi Yamakawa also participated in the signing.
“The quest for the stars is led by nations that explore the cosmos openly, in peace, and together. This is true for the United States and Japan under the leadership of President Biden and Prime Minister Kishida,” said Nelson. “America no longer will walk on the Moon alone. With this new rover, we will uncover groundbreaking discoveries on the lunar surface that will benefit humanity and inspire the Artemis Generation.”
An enclosed and pressurized rover will enable astronauts to travel farther and conduct science in geographically diverse areas by serving as a mobile habitat and laboratory for the astronauts to live and work for extended periods of time. It will be able to accommodate two astronauts for up to 30 days as they traverse the area near the lunar South Pole. NASA currently plans to use the pressurized rover on Artemis VII and subsequent missions over an approximate 10-year lifespan.
“It was an honor to sign the historic implementing arrangement that will be long remembered as the symbol of the new era of Japan-U.S. partnership for the lunar exploration,” said Moriyama. “Under the partnership stronger than ever, we will drive the initiative together with JAXA, including the development of the pressurized rover that vastly extends the exploration capability on the lunar surface, to realize the shared goal for Japanese and American astronauts to, together, explore the moon.”
The arrangement falls under the “Framework Agreement Between the Government of Japan and the Government of the United States of America for Cooperation in Space Exploration and Use of Outer Space, Including the Moon and Other Celestial Bodies, For Peaceful Purposes,” which was signed in January 2023 and recognizes the nations’ mutual interest in peaceful exploration.
The framework agreement facilitates a broad swath of joint activities between the countries, including space science, Earth science, space operations and exploration, aeronautical science and technology, space technology, space transportation, safety, and mission assurance, and much more. In addition to the agreement for lunar surface exploration, the partners will build on the framework agreement with future agreements for Japan’s participation in NASA’s Dragonfly mission and the Nancy Grace Roman Space Telescope. The U.S. and Japan also intend to collaborate on JAXA’s Next-generation Solar-observing Satellite, SOLAR-C, which will investigate the mysteries of solar atmospheres by conducting observations of ultraviolet radiation from the Sun.
“The pressurized rover will be a powerful contribution to the overall Artemis architecture as Japan and the U.S. go hand in hand with international and industry partners to the lunar surface and beyond,” said Yamakawa. “JAXA is ready to assist MEXT and push this forward with our science and technological expertise to establish sustainable human presence on the Moon.”
Under the Gateway Implementing Arrangement signed in 2022, NASA will also provide an opportunity for a Japanese astronaut to serve as a Gateway crew member on a future Artemis mission and Japan will provide Gateway’s environmental control and life support systems and cargo transportation.
Through Artemis, NASA will land the first woman, first person of color, and its first international partner astronaut on the Moon, make new scientific discoveries, and explore more of the lunar surface than ever before for the benefit of all.

More Than 36,000 Volunteers Helped Do NASA Eclipse Science
Clinton Lewis from New Harmony, IN/Western Kentucky University
Thank you for helping us out! Over 36,000 people helped do NASA Science during Monday’s total solar eclipse. Together, these volunteers submitted more than 60,000 vital pieces of eclipse data to NASA science projects.
More than 30,000 volunteers with the SunSketcher project pointed their smartphones toward the Sun and recorded pictures of Bailey’s beads, flashes of Sunlight coming through valleys on the moon. These pictures will reveal the size and shape of the Sun to high precision.
Volunteers with GLOBE Observer (GO) submitted more than 35,000 data points to the GO Eclipse, GO Clouds, and GO Landcover projects, taking eclipse data using their cell phones and sometimes thermometers. These data show the effect of the eclipse on our atmosphere.
Many more volunteers used specialized gear—DSLR cameras, telescopes, audiomoth recorders, and Ham Radio sets—taking data for the Dynamic Eclipse Broadcast Initiative, the Eclipse Megamovie project, Citizen CATE 2024, Eclipse Soundscapes, and the HamSCI project. These data will trace plumes and ejections of matter in the solar corona, track waves in the ionosphere, and reveal how animals, birds and insects reacted to the eclipse.
“I’m fascinated by the idea that the eclipse can affect the behavior of animals!” said one Eclipse Soundscapes volunteer. “I hope you all get a good data set and am still very excited to see the results! It was awesome!” said a SunSketcher volunteer.
Science is a methodical process and sometimes a slow process. Data are still arriving from cell phones and computers around the country. It will probably take months or even years for scientists to check and analyze the data, compare it with data on previous eclipses, and publish it in the refereed scientific literature.
But stay tuned as the Heliophysics Big Year continues! There will probably be some beautiful pictures coming out in the days and weeks to come thanks to your efforts.
