NASA’s TESS Returns to Science Operations
2 min read
NASA’s TESS Returns to Science OperationsNASA’s TESS (Transiting Exoplanet Survey Satellite) has returned to work after science observations were suspended on April 8, when the spacecraft entered into safe mode. All instruments are powered on and, following the successful download of previously collected science data stored in the mission’s recorder, are now making new science observations.
Analysis of what triggered the satellite to enter safe mode is ongoing.
The TESS mission is a NASA Astrophysics Explorer operated by MIT in Cambridge, Massachusetts. Launched in 2018, TESS has been scanning almost the entire sky looking for planets beyond our solar system, known as exoplanets. The TESS mission has also uncovered other cosmic phenomena, including star-shredding black holes and stellar oscillations. Read more about TESS discoveries at nasa.gov/tess.

By Celine Smith
More than 100,000 people from across the world gathered April 8 in Russellville, Arkansas, to witness an astronomical syzygy – the alignment of the Sun, Moon, and Earth – creating a solar eclipse with totality lasting 4 minutes and 12 seconds.
Team members from NASA’s Marshall Space Flight Center and others traveled to Arkansas to provide educational opportunities related to the eclipse. Experts from NASA’s Stennis Space Center, Kennedy Space Center, and NASA Headquarters, along with representatives of the Arkansas Air National Guard and the Paris Observatory in Muedon, France, joined the Marshall team.
The April 8 total solar eclipse reveals the red-glowing loops of solar prominences, large, bright features of plasma extending outward from the Sun’s surface.NASA/Joel Kowsky“I’ve conducted outreach before, but nothing on this scale,” said Patrick Koehn, heliophysics research and analysis lead at NASA Headquarters. “The logistics were on another level, it was impressive to see it come together, and I’m thrilled we engaged so many people.”
In the days leading up to the eclipse, NASA hosted exhibits and outreach activities for the public and gave presentations for students at Arkansas Tech University and the Russellville School District. Visitors were also given an opportunity to meet retired NASA astronaut Mike Massimino, who signed autographs and greeted the crowds.
Crowds from across the world gather to watch NASA presentations in Russellville, Arkansas, prior to viewing the total solar eclipse April 8. NASA/Christopher BlairMarshall Center Director Joseph Pelfrey also attended this celestial experience, giving remarks at the Russellville watch party about the eclipse and the work of Marshall’s Heliophysics and Planetary Science Branch.
“Thanks to our collaboration with the city of Russellville, we helped host one of the agency’s most successful eclipse events,” Pelfrey said. “People came from across the nation and the world to share the experience with us. It was incredible to witness my first total solar eclipse alongside the Marshall team in Arkansas.”
Bob Loper, NASA Marshall Space Flight Center research astrophysicist, conducts an eclipse presentation for students at the Center for the Arts in Russellville, Arkansas, on April 5. NASA/Christopher BlairRussellville was one of the cities featured in NASA’s live eclipse broadcast, 2024 Total Solar Eclipse: Through the Eyes of NASA. The three-hour broadcast covered the path of the eclipse across 15 states, from Texas to Maine, garnering more than one million live viewers. Currently, the broadcast has more than 13 million views. Russellville was noted for its clear skies, providing spectators with one of the most visible sightings of the eclipse.
The 2024 solar eclipse was especially spectacular due to the prominences visible during totality. Solar protected cameras captured the fiery red arcs around the edge of the Moon and Sun.

Public Invited to NASA’s 30th Anniversary of International Rover CompetitionNASA will celebrate the 30th anniversary of the Human Exploration Rover Challenge when the competition returns to the U.S. Space & Rocket Center’s Aviation Challenge Course in Huntsville April 19-20. The event is free and open to the public with rover excursions occurring each day from 7:30 a.m. to 3 p.m. or until the last rover completes the obstacle course.
NASA selected 72 student teams in October to begin an engineering design challenge to build human-powered rovers that will compete at the course near the agency’s Marshall Space Flight Center.
Students from Alabama A&M University compete during NASA’s 2023 Human Exploration Rover Challenge. The 2024 competition takes place April 19-20 at the U.S. Space & Rocket Center’s Aviation Challenge course in Huntsville. NASA/Charles BeasonThe public is invited to watch more than 600 students from around the world attempt to navigate a complex obstacle course by piloting a human-powered vehicle of their own design and production.
Participating teams represent 42 colleges and universities and 30 high schools from 24 states, the District of Columbia, Puerto Rico, and 13 other nations from around the world. NASA’s handbook has complete proposal guidelines and task challenges.
To conclude the 2024 season, NASA will host an in-person awards ceremony April 20 at 5 p.m. inside the Space Camp Operations Center at the rocket center. NASA and industry representatives will present multiple awards highlighting team successes throughout the past eight-month-long engineering design project, including awards for best rover design, best pit crew award, best social media presence, and many other accomplishments.
The Human Exploration Rover Challenge tasks high school, college, and university students around the world to design, build, and test their lightweight, human-powered rovers on a course simulating lunar and Martian terrain, all while completing mission-focused science tasks. Eligible teams compete to be among the top three finishers in their divisions, and to win awards for best vehicle design, best rookie team, and more.
The challenge annually draws hundreds of students from around the world and reflects the goals of NASA’s Artemis campaign, which will land the first woman and first person of color on the Moon.
The event was launched in 1994 as the NASA Great Moonbuggy Race – a collegiate competition to commemorate the 25th anniversary of the Apollo 11 lunar landing. It expanded in 1996 to include high school teams, evolving again in 2014 into the NASA Human Exploration Rover Challenge. Since its inception, more than 15,000 students have participated. Many former competitors now work in the aerospace industry, including with NASA.
The Human Exploration Rover Challenge is managed by NASA’s Southeast Regional Office of STEM Engagement at Marshall and is one of eight Artemis Student Challenges. NASA’s Office of STEM Engagement uses challenges and competitions to further the agency’s goal of encouraging students to pursue degrees and careers in science, technology, engineering, and mathematics.
First-of-its-kind SLS Payload Adapter Finishes Assembly at MarshallTeams at NASA’s Marshall Space Flight Center completed a new payload adapter test article and readied it for structural testing, set to begin later this spring. This marks a critical milestone on the journey to the hardware’s debut on the upgraded Block 1B configuration of NASA’s SLS (Space Launch System) rocket with Artemis IV.
The composite payload adapter is an evolution from the Orion stage adapter used in the Block 1 configuration of the first three Artemis missions.

Altitude Chamber Gets Upgrade for Artemis II, Spacecraft Testing BeginsBefore 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 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.
On April 4, a team lifts the Artemis II Orion spacecraft into a vacuum chamber inside the Operations and Checkout Building at NASA’s Kennedy Space Center, where it will undergo electromagnetic compatibility and interference testing.Photo credit: NASA/Amanda StevensonTo 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. 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.
On April 4, teams loaded the Artemis II spacecraft into the altitude chamber. 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.
After Apollo, the chambers were used for leak tests on pressurized modules delivered by the Space Shuttle Program for the International Space Station.
Additional upgrades to the west chamber include a new oxygen deficiency monitoring system that provides real-time monitoring of the oxygen levels and a new airflow system. 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.”
NASA’s Artemis II mission will carry four astronauts aboard the agency’s Orion spacecraft on an approximately 10-day test flight around the Moon and back to Earth, the first crewed flight under Artemis that will test Orion’s life support systems ahead of future missions. Under the Artemis campaign, NASA will return humanity to the lunar surface, this time sending humans to explore the lunar South Pole region.

Media Get Close-Up of NASA’s Jupiter-Bound Europa ClipperEngineers at NASA’s Jet Propulsion Laboratory 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. 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 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 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.
Members of the media visited a clean room at JPL on 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 on a six-year journey to the Jupiter system, where it will study the ice-encased moon Europa.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 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,” Evans said. “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.
Europa 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. APL designed the main spacecraft body in collaboration with JPL and NASA’s Goddard Space Flight Center. The Planetary Missions Program Office at NASA’s Marshall Space Flight Center executes program management of the Europa Clipper mission.
Hubble Spots a Galaxy Hidden in a Dark CloudThe subject of an 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 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.
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. Shatz)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.
NASA’s Dragonfly Rotorcraft Mission to Saturn’s Moon Titan ConfirmedNASA has confirmed its Dragonfly rotorcraft mission to Saturn’s organic-rich moon Titan. The decision allows the mission to progress to completion of final design, followed by the construction and testing of the entire spacecraft and science instruments.
“Dragonfly is a spectacular science mission with broad community interest, and we are excited to take the next steps on this mission,” said Nicky Fox, associate administrator, Science Mission Directorate at NASA Headquarters. “Exploring Titan will push the boundaries of what we can do with rotorcraft outside of Earth.”
Artist’s concept of Dragonfly soaring over the dunes of Saturn’s moon Titan. NASA/Johns Hopkins APL/Steve GribbenIn early 2023, the mission successfully passed all the success criteria of its Preliminary Design Review. At that time, however, the mission was asked to develop an updated budget and schedule to fit into the current funding environment. This updated plan was presented and conditionally approved in November 2023, pending the outcome of the fiscal year 2025 budget process. In the meantime, the mission was authorized to proceed with work on final mission design and fabrication to ensure that the mission stayed on schedule.
With the release of the president’s fiscal year 2025 budget request, Dragonfly is confirmed with a total lifecycle cost of $3.35 billion and a launch date of July 2028. This reflects a cost increase of about two times the proposed cost and a delay of more than two years from when the mission was originally selected in 2019. Following that selection, NASA had to direct the project to replan multiple times due to funding constraints in fiscal years 2020 through 2022. The project incurred additional costs due to the COVID-19 pandemic, supply chain increases, and the results of an in-depth design iteration. To compensate for the delayed arrival at Titan, NASA also provided additional funding for a heavy-lift launch vehicle to shorten the mission’s cruise phase.
The rotorcraft, targeted to arrive at Titan in 2034, will fly to dozens of promising locations on the moon, looking for prebiotic chemical processes common on both Titan and the early Earth before life developed. Dragonfly marks the first time NASA will fly a vehicle for science on another planetary body. The rotorcraft has eight rotors and flies like a large drone.
Dragonfly is being designed and built under the direction of the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, which manages the mission for NASA. Elizabeth Turtle of APL is the principal investigator. The team includes key partners at NASA’s Goddard Space Flight Center; Lockheed Martin Space in Littleton, Colorado; NASA’s Ames Research Center; NASA’s Langley Research Center; Penn State University in State College, Pennsylvania; Malin Space Science Systems in San Diego, California; Honeybee Robotics in Pasadena, California; NASA’s Jet Propulsion Laboratory; CNES (Centre National d’Etudes Spatiales) in Paris; the German Aerospace Center (DLR) in Cologne, Germany; and JAXA (Japan Aerospace Exploration Agency) in Tokyo.
Dragonfly is the fourth mission in NASA’s New Frontiers Program, managed by NASA’s Marshall Space Flight Center for the agency’s Science Mission Directorate.

NASA’s Near Space Network Enables PACE Climate Mission to ‘Phone Home’
The PACE (Plankton, Aerosol, Cloud, ocean Ecosystem) mission has delivered its first operational data back to researchers, a feat made possible in part by innovative, data-storing technology from NASA’s Near Space Network, which introduced two key enhancements for PACE and other upcoming science missions.
As a satellite orbits in space, its systems generate critical data about the spacecraft’s health, location, battery life, and more. All of this occurs while the mission’s science instruments capture images and data supporting the satellite’s overall objective.

Animation of NASA's PACE mission transmitting data to Earth through NASA's Near Space Network. NASA/Kasey DillahayThis data is then encoded and sent back to Earth via radio waves through NASA’s Near Space Network and Deep Space Network — but not without challenges.
One challenge is extreme distances, where disruptions or delays are common. Satellite disruptions are similar to what internet users experience on Earth with buffering or faulty links. If a disruption occurs, Delay/Disruption Tolerant Networking, or DTN, can safely store and forward the data once a path opens.
NASA’s Near Space Network integrated DTN into four new antennas and the PACE spacecraft to showcase the benefit this technology can have for science missions. The network, which supports communications for space-based mission within 1.2 million miles of Earth, is constantly enhancing its capabilities to support science and exploration missions.
DTN is the future of space communications, providing robust protection of data that could be lost due to a disruption.”Kevin Coggins
Deputy Associate Administrator for NASA SCaN
“DTN is the future of space communications, providing robust protection of data that could be lost due to a disruption,” said Kevin Coggins, deputy associate administrator for NASA’s Space Communications and Navigation (SCaN) program. “PACE is the first operational science mission to leverage DTN, and we are using it to transmit data to mission operators monitoring the batteries, orbit, and more. This information is critical to mission operations.”
PACE, a satellite located about 250 miles above Earth, is collecting data to help researchers better understand how the ocean and atmosphere exchange carbon dioxide, measure atmospheric variables associated with air quality and climate, and monitor ocean health by studying phytoplankton — tiny plants and algae.
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. NASAWhile PACE is the first operational science user of DTN, demonstrations of the technology have been done previously on the International Space Station.
In addition to DTN, the Near Space Network worked with commercial partner, Kongsberg Satellite Services in Norway to integrate four new antennas into the network to support PACE.
These new antennas, in Fairbanks, Alaska; Wallops Island, Virginia; Punta Arenas, Chile; and Svalbard, Norway, allow missions to downlink terabytes of science data at once. Just as scientists and engineers constantly improve their instrument capabilities, NASA also advances its communications systems to enable missions near Earth and in deep space.
As PACE orbits Earth, it will downlink its science data 12 to 15 times a day to three of the network’s new antennas. Overall, the mission will send down 3.5 terabytes of science data each day.
The Near Space Network’s new antennas in Alaska, Chile, Norway, and Virginia. These were developed in partnership with KSAT. NASANetwork capability techniques like DTN and the four new antennas are the latest enhancements to the Near Space Network’s catalog of services to support science missions, human spaceflight, and technology experiments.
“NASA’s Near Space Network now has unprecedented flexibility to get scientists and operations managers more of the precious information they need to ensure their mission’s success,” said Coggins.

NASA/Kasey DillahayIn addition to these new capabilities, the network is also increasing the number of commercial antennas within its portfolio. In 2023, NASA issued the Near Space Network Services request for proposal to seek commercial providers for integration into the network’s expanding portfolio. With an increasing capacity, the network can support additional science missions and downlink opportunities.
The Near Space Network is funded by NASA’s Space Communications and Navigation (SCaN) program office at NASA Headquarters in Washington and operated out of NASA’s Goddard Space Flight Center in Greenbelt, Maryland.

Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA research pilot Nils Larson and photographer Jim Ross complete aerobatic maneuvers in a NASA Armstrong Flight Research Center in Edwards, California owned T-34C aircraft during a proficiency flight. NASA/Jim RossRiding in the back seat of a car can be boring. Riding in the back of a NASA aircraft is exhilarating, especially for photographers capturing NASA’s story. Jim Ross, photo lead at NASA’s Armstrong Flight Research Center in Edwards, California, was awarded first place for an image he took while flying upside down in a two-seat T-34C research aircraft.
In the photo, which was announced as the NASA Photo of the Year 2023 in the People category on April 15, 2024. Ross captures NASA research pilot Nils Larson in full flight gear, while the aircraft is doing aerobatic maneuvers. Most of us would struggle to keep our bearings, let alone operate a camera and frame a perfectly balanced image. NASA Armstrong photographers do this every flight day.
“When we fly proficiency flights, my mind is always thinking about what kind of photo I can take that will share what I am experiencing in the aircraft,” Ross said. “This photo was one that I feel is able to tell that story.” It’s telling the story that makes Ross’s work so important to NASA. Much of what NASA works on can only be witnessed by researchers and scientists, but having it capture in photo and video allows us to share the images with the world.
Jim Ross, photo lead at NASA’s Armstrong Flight Research Center in Edwards, California, took a photo of an aerobatic maneuver from the back seat of a T-34C that was selected as first place in the NASA Photo of the Year 2023 Contest in the People category.NASA/Genaro VavurisRoss began his aviation photography career in 1989 when he joined the photography staff at NASA’s Armstrong (then Dryden) Flight Research Center, now known as NASA Armstrong. He became the photo lead in 1997, a title he retains. In his 30 years of flying, he has flown on more than 900 missions and has about 1,100 flight hours in aircraft including T-33, T-34, T-38, F-15, F-16, F-18, KC-10, KC-135, C-12, C-20A, Boeing 747SP, and helicopters.
NASA previously recognized Ross for his work with the agency’s Public Service Medal and the Exceptional Public Achievement Medal. NASA also made a photo book of his work titled, “NASA Photo One,” which highlights 100 photos of his career. He also won the Best of the Best award from the Aviation Week & Space Technology photo contest in 2001. His work has appeared in many publications, including Aviation Week & Space Technology, National Geographic, and Air & Space Smithsonian.

A NASA mission testing a new way of navigating our solar system is ready to hoist its sail into space – not to catch the wind, but the propulsive power of sunlight. The Advanced Composite Solar Sail System is targeting launch on Tuesday, April 23 (Wednesday, April 24 in New Zealand) aboard a Rocket Lab Electron rocket from the company’s Launch Complex 1 on the Mahia Peninsula of New Zealand.
Rocket Lab’s Electron rocket will deploy the mission’s CubeSat about 600 miles above Earth – more than twice the altitude of the International Space Station. To test the performance of NASA’s Advanced Composite Solar Sail System, the spacecraft must be in a high enough orbit for the tiny force of sunlight on the sail – roughly equivalent to the weight of a paperclip resting on your palm – to overcome atmospheric drag and gain altitude.
After a busy initial flight phase, which will last about two months and includes subsystems checkout, the microwave oven-sized CubeSat will deploy its reflective solar sail. The weeks-long test consists of a series of pointing maneuvers to demonstrate orbit raising and lowering, using only the pressure of sunlight acting on the sail.
Stay tuned for updates as NASA’s Advanced Composite Solar Sail System sets out to prove its ability to sail across space, increasing access and enabling low-cost missions to the Moon, Mars, and beyond.
NASA’s Ames Research Center in California’s Silicon Valley manages the project and designed and built the onboard camera diagnostic system. NASA’s Langley Research Center in Langley, Virginia, designed and built the deployable composite booms and solar sail system. NASA’s Small Spacecraft Technology (SST) program office, within the agency’s Space Technology Mission Directorate (STMD), funds and manages the mission. STMD’s Game Changing Development program developed the deployable composite boom technology. Rocket Lab USA, Inc of Long Beach, California, is providing launch services.
