Preparations for Next Moonwalk Simulations Underway (and Underwater)NASA’s broad reach across digital platforms has been recognized by the International Academy of Digital Arts and Sciences (IADAS), which awarded NASA 6 Webbys in the 28th Annual Webby Awards.
Editor’s Note: This article has been updated to add Hubble’s Inside the Image to the list of Webby Award wins.
NASA was recognized today by the 28th Annual Webby Awards with six Webby Awards and eight Webby People’s Voice Awards, the latter of which are awarded by the voting public. The Webbys honors excellence in nine major media types: websites and mobile sites, video, advertising, media and public relations, apps and software, social media, podcasts, games, the metaverse, and virtual and artificial intelligence (AI).
“We’re thrilled that the Webbys have recognized the breadth of NASA’s digital communications,” said Marc Etkind, associate administrator for communications. “To have a podcast, a virtual exhibit, live streaming, social and web all honored shows how our skilled and accomplished our team is. We’re especially pleased to see awards recognizing our reinvigorated digital platforms, including the NASA website and NASA+ streaming service. Together with the science website and NASA app, they are the core of our digital communications.”
The broad scope of the awards also highlights the agency’s enterprise approach to communications. For example, live streams are produced and led by the Office of Communications at NASA Headquarters in Washington. Each program, however, originates from within projects at NASA centers and represents many months of logistical preparation, rehearsals and constant review and adjustment. Once the TV streams are set, they are hosted on NASA’s website and fed to NASA’s social media channels, where the agency team engages with the live audience, providing background context and answering questions. All the while, agency photographers are documenting the effort and posting pictures to digital platforms while NASA’s audio team is gather sound and interviews to continue telling the story via podcasts.
Since 1998, NASA has been nominated for more than 100 Webby Awards, winning 37 Webbys and 53 People’s Voice Awards.

Sols 4164-4165: What’s Around the Ridge-bend?

Sols 4164-4165: What’s Around the Ridge-bend? This image was taken by the Left Navigation Camera and looks towards the deposits that make up the bend in Gediz Vallis ridge between “Pinnacle Ridge” and “Fascination Turret”. In the background is the layered stratigraphy that makes up the butte “Texoli”. NASA/JPL-CaltechEarth planning date: Monday, April 22, 2024
Curiosity succeeded on a ~14 m drive along a bend in upper Gediz Vallis ridge (uGVR) to park next to “Pinnacle Ridge,” an outcrop of uGVR to the north. Benefitting from a surplus in power, Curiosity’s already substantial targeted science block was extended to 2 hours. This allowed for the perfect imaging opportunity to look back and investigate the ridge deposits between “Pinnacle Ridge” and “Fascination Turret,” an outcrop of uGVR to the south. In other words, most of the imaging opportunities in this two-sol plan will be spent documenting what’s just around the ridge-bend with a detailed Mastcam stereo-mosaic and two ChemCam Long Distance RMI mosaics.
Today I served as Keeper of the Plan for the Geology and Mineralogy Theme Group, where I was kept busy recording all of the geology related requests from the instrument teams. The first sol involved planning contact science on a nearby dark-toned float block, “Sluggo Pass,” possibly originating from Gediz Vallis ridge. The composition and sedimentary textures of “Sluggo Pass” will be investigated with the Alpha Particle X-Ray Spectrometer (APXS), a ChemCam passive raster, and the Mars Hand Lens Imager (MAHLI). While constraints prevented brushing “Sluggo Pass” with the Dust Removal Tool (DRT), the target appeared to be relatively dust-free. The rest of the science plan on the first sol includes a ChemCam Laser-Induced Breakdown Spectroscopy (LIBS) targeting a dark-toned coating on light-toned bedrock, dubbed ‘South Lake,’ and two small Mastcam mosaics on blocks possibly associated with “Pinnacle Ridge.”
After a planned ~31 m drive from our current location, the focus of the second sol of the plan will be on untargeted remote science. This includes one of ChemCam’s automated AEGIS (Autonomous Exploration for Gathering Increased Science) activities where geological targets are automatically selected from the rover’s navigation cameras for analysis with ChemCam. Additionally, environmental activities were also planned, including tau observations to assess the amount of dust in the atmosphere and Mastcam deck monitoring activities to assess the amount of dust accumulated on the rover deck.

First NASA Mars Analog Crew Nears End of Mission
The first crew to take part in a yearlong NASA Mars analog mission reached the 300-day mark of its mission on April 20.
The team of four volunteers entered the CHAPEA (Crew Health and Performance Exploration Analog) habitat at NASA’s Johnson Space Center in Houston on June 25, 2023, and is expected to complete the mission on July 6, 2024.
During their 300 days in the ground-based habitat, the crew engaged in multiple simulated “Marswalks,” grew and harvested several salad crops to occasionally supplement their shelf-stable food, and took part in habitat and equipment maintenance.
NASA is leading a return to the Moon for long-term science and exploration. Through Artemis missions, NASA will land the first woman, first person of color, and first international partner astronaut on the Moon, using innovative technologies to explore more of the lunar surface than ever before. Lessons learned on and around the Moon and activities like CHAPEA on the ground will prepare NASA for the next giant leap: sending astronauts to Mars.

Over the course of nearly two decades, its powerful radar provided never-before-seen details of clouds and helped advance global weather and climate predictions.
CloudSat, a NASA mission that peered into hurricanes, tallied global snowfall rates, and achieved other weather and climate firsts, has ended its operations. Originally proposed as a 22-month mission, the spacecraft was recently decommissioned after almost 18 years observing the vertical structure and ice/water content of clouds.
As planned, the spacecraft — having reached the end of its lifespan and no longer able to make regular observations — was lowered into an orbit last month that will result in its eventual disintegration in the atmosphere.
When launched in 2006, the mission’s Cloud Profiling Radar was the first-ever 94 GHz wavelength (W-band) radar to fly in space. A thousand times more sensitive than typical ground-based weather radars, it yielded a new vision of clouds — not as flat images on a screen but as 3D slices of atmosphere bristling with ice and rain.
For the first time, scientists could observe clouds and precipitation together, said Graeme Stephens, the mission’s principal investigator at NASA’s Jet Propulsion Laboratory in Southern California. “Without clouds, humans wouldn’t exist, because they provide the freshwater that life as we know it requires,” he said. “We sometimes refer to them as clever little devils because of their confounding properties. Clouds have been an enigma in terms of predicting climate change.”
NASA’s CloudSat passed over Hurricane Bill near the U.S. East Coast in August 2009, capturing data from the Category 4 storm’s eye. This pair of images shows a view from the agency’s Aqua satellite (top) along with the vertical structure of the clouds measured by CloudSat’s radar (bottom).Jesse Allen, NASA Earth ObservatoryClouds have long held many secrets. Before CloudSat, we didn’t know how often clouds produce rain and snow on a global basis. Since its launch, we’ve also come a long way in understanding how clouds are able to cool and heat the atmosphere and surface, as well as how they can cause aircraft icing.
CloudSat data has informed thousands of research publications and continues to help scientists make key discoveries, including how much ice and water clouds contain globally and how, by trapping heat in the atmosphere, clouds accelerate the melting of ice in Greenland and at the poles.
Weathering the StormOver the years, CloudSat flew over powerful storm systems with names like Maria, Harvey, and Sandy, peeking beneath their swirling canopies of cirrus clouds. Its Cloud Profiling Radar excelled at penetrating cloud layers to help scientists explore how and why tropical cyclones intensify.

Areas of high reflectivity, shown in red and pink, extend above 9 miles (15 kilometers) in height, indicating large amounts of water being drawn upward high into the atmosphere. Credit: NASA/JPL-Caltech/CIRAAcross the life of CloudSat, several potentially mission-ending issues occurred related to the spacecraft’s battery and to the reaction wheels used to control the satellite’s orientation. The CloudSat team developed unique solutions, including “hibernating” the spacecraft during nondaylight portions of each orbit to conserve power, and orienting it with fewer reaction wheels. Their solutions allowed operations to continue until the Cloud Profiling Radar was permanently turned off in December 2023.
“It’s part of who we are as a NASA family that we have dedicated and talented teams that can do things that have never before been done,” said Deborah Vane, CloudSat’s project manager at JPL. “We recovered from these anomalies with techniques that no one has ever used before.”
Sister SatellitesCloudSat was launched on April 28, 2006, in tandem with a lidar-carrying satellite called CALIPSO (short for the Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observation). The two spacecraft joined an international constellation of weather- and climate-tracking satellites in Earth orbit.
Radar and lidar are considered “active” sensors because they direct beams of energy at Earth — radio waves in the case of CloudSat and laser light in the case of CALIPSO — and measure how the beams reflect off the clouds and fine particles (aerosols) in the atmosphere. Other orbiting science instruments use “passive” sensors that measure reflected sunlight or radiation emitted from Earth or clouds.
Orbiting less than a minute apart, CloudSat and CALIPSO circled the globe in Sun-synchronous orbits from the North to the South Pole, crossing the equator in the early afternoon and after midnight every day. Their overlapping radar-lidar footprint cut through the vertical structure of the atmosphere to study thin and thick clouds, as well as the layers of airborne particles such as dust, sea salt, ash, and soot that can influence cloud formation.
The influence of aerosols on clouds remains a key question for global warming projections. To explore this and other questions, the recently launched PACE satellite and future missions in NASA’s Earth System Observatory will build upon CloudSat’s and CALIPSO’s legacies for a new generation.
“Earth in 2030 will be different than Earth in 2000,” Stephens said. “The world has changed, and the climate has changed. Continuing these measurements will give us new insights into changing weather patterns.”

Hubble Spots the Little Dumbbell Nebula
To celebrate the 34th anniversary of the Hubble Space Telescope’s launch, the telescope captured an image of the Little Dumbbell Nebula, or M76. M76 is a planetary nebula, an expanding shell of glowing gases that were ejected from a dying red giant star that eventually collapses to an ultra-dense and hot white dwarf. It gets its descriptive name from its shape: a ring, seen edge-on as the central bar structure, and two lobes on either opening of the ring.
Since its launch in 1990 Hubble has made 1.6 million observations of over 53,000 astronomical objects. Most of Hubble’s discoveries were not anticipated before launch, such as supermassive black holes, the atmospheres of exoplanets, gravitational lensing by dark matter, the presence of dark energy, and the abundance of planet formation among stars.

Launched on June 11, 2008, Fermi detects gamma rays, the highest-energy form of light, from Earth’s atmosphere to far-flung galaxies and cosmic phenomena in between. Its research has uncovered details on topics ranging from solar flares to star formation and the mysteries at the center of our Milky Way.
Through images, fun facts, and launch-day memories, the e-book tells Fermi’s story from conceptualization to launch and recounts some of the mission’s groundbreaking discoveries. By delving into high-energy astrophysics topics like gamma-ray bursts and blazars, readers can explore Fermi’s universe and what questions remain open for investigation in its next chapter.
Fermi was originally called the Gamma-ray Large Area Space Telescope but was renamed after Italian physicist Enrico Fermi in August 2008.
“Enrico Fermi’s science has been important for understanding the sources that the Fermi telescope sees,” said Elizabeth Hays, the mission’s project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “The gamma-ray sky is powered by particle acceleration mechanisms he theorized about.”
The satellite has two gamma-ray detectors: the Large Area Telescope (LAT) and the Gamma-ray Burst Monitor (GBM).
The LAT observes a fifth of the gamma-ray sky at any time, detecting high-energy light with energies ranging from 20 million to over 300 billion electron volts. (The energy of visible light is 2 to 3 electron volts.) The GBM views about 70% of the sky at a time at lower energies, searching for brief flashes of gamma-ray light.
The result of this carefully crafted duo is the most sensitive gamma-ray observatory in orbit, equipped to study the universe’s highest-energy phenomena near and far.
By peering through Fermi’s gamma-ray eyes, we can better understand our solar system. Within its first eight years of operation, Fermi detected gamma-ray emissions from 40 solar flares — bursts of energy from the Sun. Some even originated on the Sun’s far side, allowing scientists to analyze how charged particles fired by solar flares can arc from one side of the Sun to produce gamma rays on the other.
In studying our Milky Way, Fermi found two lobes of high-energy gamma rays — called the Fermi Bubbles — extending above and below the galaxy’s center. Each bubble stands 25,000 light-years tall. Astronomers think the bubbles formed following an ancient burst of activity from the Milky Way’s central supermassive black hole.
Fermi helps scientists understand black holes in other galaxies, too.
“As a black hole forms, either from the death of a massive star or the collision of two neutron stars, it creates a brief flash of light called a gamma-ray burst,” said Judith Racusin, Fermi’s deputy project scientist at Goddard. “Fermi detects about one burst a day and has helped revolutionize our understanding of these phenomena.”
Even after 15 years of accomplishments, however, many mysteries remain for Fermi to tackle. One of the telescope’s ongoing objectives is to study the composition of dark matter — the mysterious substance that makes up about 25% of the universe.
Because dark matter doesn’t reflect, absorb, or emit light, scientists remain unsure of its composition. One popular theory suggests, though, that dark matter particles create gamma rays when they interact. If Fermi can spot this high-energy signature, it might help scientists learn more about dark matter’s makeup.
If there’s one thing Fermi has taught us, it’s to expect the unexpected. Gamma-ray research has yielded unprecedented breakthroughs in our understanding of the Milky Way’s central black hole, our flaring Sun, and merging neutron stars. As much as we anticipate the next gamma-ray revelation, only time will tell what exactly Fermi has in store.
Fermi is an astrophysics and particle physics partnership managed by Goddard. Fermi was developed in collaboration with the U.S. Department of Energy, with important contributions from academic institutions and partners in France, Germany, Italy, Japan, Sweden, and the United States.

Hubble Celebrates 34th Anniversary with a Look at the Little Dumbbell Nebula

Hubble Celebrates 34th Anniversary with a Look at the Little Dumbbell NebulaIn celebration of the 34th anniversary of the launch of NASA’s legendary Hubble Space Telescope on April 24, astronomers took a snapshot of the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651) located 3,400 light-years away in the northern circumpolar constellation Perseus. The photogenic nebula is a favorite target of amateur astronomers.
In celebration of the 34th anniversary of the launch of NASA’s legendary Hubble Space Telescope, astronomers took a snapshot of the Little Dumbbell Nebula, also known as Messier 76, or M76, located 3,400 light-years away in the northern circumpolar constellation Perseus. The name ‘Little Dumbbell’ comes from its shape that is a two-lobed structure of colorful, mottled, glowing gases resembling a balloon that’s been pinched around a middle waist. Like an inflating balloon, the lobes are expanding into space from a dying star seen as a white dot in the center. Blistering ultraviolet radiation from the super-hot star is causing the gases to glow. The red color is from nitrogen, and blue is from oxygen. NASA, ESA, STScIDownload this image (3MB)

M76 is classified as a planetary nebula, an expanding shell of glowing gases that were ejected from a dying red giant star. The star eventually collapses to an ultra-dense and hot white dwarf. A planetary nebula is unrelated to planets, but have that name because astronomers in the 1700s using low-power telescopes thought this type of object resembled a planet.
M76 is composed of a ring, seen edge-on as the central bar structure, and two lobes on either opening of the ring. Before the star burned out, it ejected the ring of gas and dust. The ring was probably sculpted by the effects of the star that once had a binary companion star. This sloughed off material created a thick disk of dust and gas along the plane of the companion’s orbit. The hypothetical companion star isn’t seen in the Hubble image, and so it could have been later swallowed by the central star. The disk would be forensic evidence for that stellar cannibalism.
The primary star is collapsing to form a white dwarf. It is one of the hottest stellar remnants known at a scorching 250,000 degrees Fahrenheit, 24 times our Sun’s surface temperature. The sizzling white dwarf can be seen as a pinpoint in the center of the nebula. A star visible in projection beneath it is not part of the nebula.
Pinched off by the disk, two lobes of hot gas are escaping from the top and bottom of the “belt,” along the star’s rotation axis that is perpendicular to the disk. They are being propelled by the hurricane-like outflow of material from the dying star, tearing across space at two million miles per hour. That’s fast enough to travel from Earth to the Moon in a little over seven minutes! This torrential “stellar wind” is plowing into cooler, slower-moving gas that was ejected at an earlier stage in the star’s life, when it was a red giant. Ferocious ultraviolet radiation from the super-hot star is causing the gases to glow. The red color is from nitrogen, and blue is from oxygen.
Given our solar system is 4.6 billion years old, the entire nebula is a flash in the pan by cosmological timekeeping. It will vanish in about 15,000 years.
Hubble’s Star Trekking
Since its launch in 1990 Hubble has made 1.6 million observations of over 53,000 astronomical objects. To date, the Mikulski Archive for Space Telescopes at the Space Telescope Science Institute in Baltimore, Maryland holds 184 terabytes of processed data that is science-ready for astronomers around the world to use for research and analysis. Since 1990, 44,000 science papers have been published from Hubble observations. The space telescope is the most scientifically productive space astrophysics mission in NASA history. The demand for using Hubble is so high it is currently oversubscribed by a factor of six-to-one.
Most of Hubble’s discoveries were not anticipated before launch, such as supermassive black holes, the atmospheres of exoplanets, gravitational lensing by dark matter, the presence of dark energy, and the abundance of planet formation among stars.
Hubble will continue research in those domains and capitalize on its unique ultraviolet-light capability on such topics as solar system phenomena, supernovae outbursts, composition of exoplanet atmospheres, and dynamic emission from galaxies. And Hubble investigations continue to benefit from its long baseline of observations of solar system objects, stellar variable phenomena and other exotic astrophysics of the cosmos.
NASA’s James Webb Space Telescope was designed to be meant to be complementary to Hubble, and not a substitute. Future Hubble research also will take advantage of the opportunity for synergies with Webb, which observes the universe in infrared light. The combined wavelength coverage of the two space telescopes expands on groundbreaking research in such areas as protostellar disks, exoplanet composition, unusual supernovae, cores of galaxies and chemistry of the distant universe.

Pushing the Limits of Sub-Kilowatt Electric Propulsion Technology to Enable Planetary Exploration and Commercial Mission Concepts
NASA has developed an advanced propulsion technology to facilitate future planetary exploration missions using small spacecraft. Not only will this technology enable new types of planetary science missions, one of NASA’s commercial partners is already preparing to use it for another purpose—to extend the lifetimes of spacecraft that are already in orbit. Identifying the opportunity for industry to use this new technology not only advances NASA’s goal of technology commercialization, it could potentially create a path for NASA to acquire this important technology from industry for use in future planetary missions.
The New TechnologyPlanetary science missions using small spacecraft will be required to perform challenging propulsive maneuvers—such as achieving planetary escape velocities, orbit capture, and more—that require a velocity change (delta-v) capability well in excess of typical commercial needs and the current state-of-the-art. Therefore, the #1 enabling technology for these small spacecraft missions is an electric propulsion system that can execute these high-delta-v maneuvers. The propulsion system must operate using low power (sub-kilowatt) and have high-propellant throughput (i.e., the capability to use a high total mass of propellant over its lifetime) to enable the impulse required to execute these maneuvers.
After many years of research and development, researchers at NASA Glenn Research Center (GRC) have created a small spacecraft electric propulsion system to meet these needs—the NASA-H71M sub-kilowatt Hall-effect thruster. In addition, the successful commercialization of this new thruster will soon provide at least one such solution to enable the next generation of small spacecraft science missions requiring up to an amazing 8 km/s of delta-v. This technical feat was accomplished by the miniaturization of many advanced high-power solar electric propulsion technologies developed over the last decade for applications such as the Power and Propulsion Element of Gateway, humanity’s first space station around the Moon.

Right: Dr. Jonathan Mackey tuning the thrust stand prior to closing and pumping down the test facility. Benefits of This Technology for Planetary ExplorationSmall spacecraft using the NASA-H71M electric propulsion technology will be able to independently maneuver from low-Earth orbit (LEO) to the Moon or even from a geosynchronous transfer orbit (GTO) to Mars. This capability is especially remarkable because commercial launch opportunities to LEO and GTO have become routine, and the excess launch capacity of such missions is often sold at low cost to deploy secondary spacecraft. The ability to conduct missions that originate from these near-Earth orbits can greatly increase the cadence and lower the cost of lunar and Mars science missions.
This propulsion capability will also increase the reach of secondary spacecraft, which have been historically limited to scientific targets that align with the primary mission’s launch trajectory. This new technology will enable secondary missions to substantially deviate from the primary mission’s trajectory, which will facilitate exploration of a wider range of scientific targets.
In addition, these secondary spacecraft science missions would typically have only a short period of time to collect data during a high-speed flyby of a distant body. This greater propulsive capability will allow deceleration and orbital insertion at planetoids for long-term scientific study.
Furthermore, small spacecraft outfitted with such significant propulsive capability will be better equipped to manage late-stage changes to the primary mission’s launch trajectory. Such changes are frequently a top risk for small spacecraft science missions with limited onboard propulsive capability that depend on the initial launch trajectory to reach their science target.
Commercial ApplicationsThe megaconstellations of small spacecraft now forming in low-Earth orbits have made low-power Hall-effect thrusters the most abundant electric propulsion system used in space today. These systems use propellant very efficiently, which allows for orbit insertion, de-orbiting, and many years of collision avoidance and re-phasing. However, the cost-conscious design of these commercial electric propulsion systems has inevitably limited their lifetime capability to typically less than a few thousand hours of operation and these systems can only process about 10% or less of a small spacecraft’s initial mass in propellant.
By contrast, planetary science missions benefiting from the NASA-H71M electric propulsion system technology could operate for 15,000 hours and process over 30% of the small spacecraft’s initial mass in propellant. This game-changing capability is well beyond the needs of most commercial LEO missions and comes at a cost premium that makes commercialization for such applications unlikely. Therefore, NASA sought and continues to seek partnerships with companies developing innovative commercial small spacecraft mission concepts with unusually large propellant throughput requirements.
One partner that will soon use the licensed NASA electric propulsion technology in a commercial small spacecraft application is SpaceLogistics, a wholly owned subsidiary of Northrop Grumman. The Mission Extension Pod (MEP) satellite servicing vehicle is equipped with a pair of Northrop Grumman NGHT-1X Hall-effect thrusters, whose design is based on the NASA-H71M. The small spacecraft’s large propulsive capability will allow it to reach geosynchronous Earth orbit (GEO) where it will be mounted on a far larger satellite. Once installed, the MEP will serve as a “propulsion jet pack” to extend the life of its host spacecraft for at least six years.
Northrop Grumman is currently conducting a long duration wear test (LDWT) of the NGHT-1X in GRC’s Vacuum Facility 11 to demonstrate its full lifetime operational capability. The LDWT is funded by Northrop Grumman through a fully reimbursable Space Act Agreement. The first MEP spacecraft are expected to launch in 2025, where they will extend the life of three GEO communication satellites.
Collaborating with U.S. industry to find small spacecraft applications with propulsive requirements similar to future NASA planetary science missions not only supports U.S. industry in remaining a global leader in commercial space systems but creates new commercial opportunities for NASA to acquire these important technologies as planetary missions require them.

Sols 4161-4163: Double Contact Science
2 min read
Sols 4161-4163: Double Contact Science This image was taken by Mast Camera (Mastcam) onboard NASA’s Mars rover Curiosity on Sol 4159 (2024-04-18 13:24:29 UTC). NASA/JPL-Caltech/MSSSEarth planning date: Friday, April 19, 2024
Curiosity has a three-sol weekend plan coming up as it makes progress along the edge of upper Gediz Vallis ridge. We have observations planned to investigate multiple bedrock targets with interesting rippled textures, dark-toned float, and the ridge. With two contact science targets, lots of targeted and untargeted remote observations, and a drive scheduled, Curiosity will have a busy three-sol plan ahead!
On the first sol of the plan, we have two contact science bedrock targets for MAHLI and APXS to analyze. MAHLI will image these targets up close, and APXS will acquire spectra from the targets for analysis of their elemental compositions. One of these bedrock targets (“Florence Lake”) is light-toned with laminations and will be brushed first to remove the dust on its surface. The other contact science target (“Mist Falls”) is a block of unbrushed, light-toned bedrock with a rippled texture. MAHLI also has a rotational stereo observation of “Castle Rock Spire” (a light-toned block of bedrock) and observations of the REMS UV sensor. In addition to bedrock observations by MAHLI and APXS, ChemCam has a LIBS observation of dark-toned float target “Silver Peak” on the first sol of this plan. ChemCam will also acquire long-distance RMIs of the rim of upper Gediz Vallis ridge and Fascination Turret to document stratigraphy. Mastcam will acquire mosaics to document exposed bedding, Kukenan butte, and Pinnacle Ridge.
Observations of Pinnacle Ridge by Mastcam will complement the ChemCam long-distance RMI observation of it on the second sol of the plan. This sol also has a ChemCam LIBS observation of “Needle Lake” to document different degrees of erosion of bedrock across laminations and a ChemCam passive dark test. Mastcam will image the two LIBS targets and will also acquire several mosaics of “Pahoa Island”, “Quail Flat”, and “The Nose” to document light-toned laminated bedrock, ripple structures, and characteristics of a dark float rock, respectively. On the second sol Curiosity will drive away. The third sol of the plan features untargeted remote observations, including ChemCam Passive Sky activities, dust devil observations, and Mastcam tau measurements.

NASA Invites Media to Learn About New Tech Mission Powered by the Sun
A new NASA mission is testing a new way to navigate our solar system by hoisting its sail into space – not to catch the wind, but the propulsive power of sunlight.
NASA’s Advanced Composite Solar Sail System is led by the agency’s Ames Research Center in California’s Silicon Valley. The microwave oven-sized CubeSat is scheduled to launch aboard a Rocket Lab Electron rocket from the company’s Launch Complex 1 on the Mahia Peninsula of New Zealand. The launch window opens at 3 p.m. PDT on Tuesday, April 23 (10 p.m. UTC). Successful deployment and operation of the solar sail’s lightweight composite booms will prove the capability and open the door to larger scale missions to the Moon, Mars, and beyond.
Once it arrives in its orbit, roughly 600 miles above Earth, the CubeSat will deploy a lightweight sunlight-powered composite solar sail system that measures more than 800 square feet. Much like a sailboat uses wind to traverse the ocean, the solar sail technology will use the pressure of sunlight to travel through space and perform a series of maneuvers to demonstrate orbit raising and lowering. Throughout the demonstration, the spacecraft may be visible to the naked eye in the night sky.
Media interested in scheduling an interview with one of the NASA Ames engineers involved with the development of the CubeSat should email the NASA Ames Office of Communications at arc-dl-newsroom@mail.nasa.gov.
A media resource reel including animated clips of the solar sail system is available here.

NASA Nurtures Promising Tech Ideas from Small Businesses
New space technology ideas emerge every day from innovators across the country, and NASA’s Small Business Innovation Research (SBIR) program on Monday selected more than 100 projects for funding. This program offers small businesses in the United States early-stage funding and support to advance the agency’s goals of exploring the unknown in air and space while returning benefits to Earth.
Specifically, NASA’s SBIR program awarded $93.5 million in Phase II contracts to bring 107 new ideas to life from 95 selected small businesses. Of these businesses, nearly 80% have less than 50 employees, and 21% are receiving their first Phase II award, valued at up to $850,000 each. Each small business was also eligible to apply for up to $50,000 in Technical and Business Assistance program funding to help find new market opportunities and shape their commercialization roadmap.
“We are thrilled to support this diverse set of companies as they work diligently to bring their technologies to market,” said Jenn Gustetic, director of Early Stage Innovation and Partnerships with NASA’s Space Technology Mission Directorate (STMD) at the agency’s headquarters in Washington. “Inclusive innovation is integral to mission success at NASA, and we’re excited to see that 29% of the awardees are from underrepresented groups, including 11% women-owned businesses.”
In Phase II, awardees will build on their success from the program’s first phase to bring their technologies closer to real-world use. The companies have 24 months to execute their plans, which focus on their technologies’ path to commercialization.
For example, NASA selected women-owned and first-time NASA Phase II awardee nou Systems, Inc. in Huntsville, Alabama, for its genetic testing instrument. While portable genetic sequencing already exists, field sequencing – that would allow DNA analysis anywhere on Earth or off planet – remains unfeasible as the preparation of the DNA Library remains an intensely manual process, needing a trained wet lab technician and several pieces of laboratory equipment. The Phase II technology takes advantage of several cross-enabling technologies, creating an instrument to automate the genetic sequencing process.
“Our program works directly with small businesses to forge innovative concepts and technologies that drive impact for NASA projects as well as a myriad of commercial endeavors,” said Jason L. Kessler, program executive for NASA’s SBIR and Small Business Technology Transfer (STTR) program at NASA Headquarters. “This collaboration results in realized opportunities not only for NASA but all of humanity.”
This includes technologies aiming to reduce astronaut workload and improve robotic scientific endeavors on the Moon and Mars. PickNik Inc. based in Boulder, Colorado, will use its Phase II award to continue developing a hardware-agnostic platform for supervised autonomy that empowers humans to command a remote robot to complete complex tasks with minimal input, which could support the Artemis program. Outside of NASA, PickNik’s software product may be of interest to commercial space customers working on low Earth orbit destinations, in-space servicing, and more, as well as on Earth in areas like warehouse management, oil rig maintenance, and deep-sea exploration.
The NASA SBIR program is open to U.S. small businesses to develop an innovation or technology. The program is part of STMD and managed by NASA’s Ames Research Center in California’s Silicon Valley.
