Hello Universe: NASA’s Next-Gen Space Processor Undergoes Testing

NASA’s High Performance Spaceflight Computing project aims to dramatically improve the computing power of spacecraft. Missions need processors that can withstand the harsh space environment, so they use chips developed years ago that are hardy and reliable. But upgraded chips are needed to enable the development of autonomous spacecraft, accelerate the rate of scientific discovery through faster data analysis, and support astronauts on missions to the Moon and Mars.

“Building on the legacy of previous space processors, this new multicore system is fault-tolerant, flexible, and extremely high-performing,” said Eugene Schwanbeck, program element manager in NASA’s Game Changing Development program at the agency’s Langley Research Center, in Hampton, Virginia. “NASA’s commitment to advancing spaceflight computing is a triumph of technical achievement and collaboration.”

The centerpiece of the High Performance Spaceflight Computing project is a new radiation-hardened, high-performance processor, designed to provide up to 100 times the computational capacity of current spaceflight computers while enduring a barrage of challenges in space. NASA’s Jet Propulsion Laboratory in Southern California has been conducting various tests that replicate those challenges.

“We are putting these new chips through the wringer by carrying out radiation, thermal, and shock tests while also evaluating their performance through a rigorous functional test campaign,” said Jim Butler, High Performance Space Computing project manager at JPL.

The processor must endure myriad tests to prove it can survive the rigors of spaceflight, including electromagnetic radiation and extreme temperature swings, both of which can degrade electronics. High-energy particles from the Sun and interstellar space can cause errors that send a spacecraft into “safe mode,” where nonessential operations are shut down until mission operators resolve the issue.

There are also unique challenges associated with landing on planetary bodies. “To simulate real-world performance, we are using high-fidelity landing scenarios from real NASA missions that would typically require power-intensive hardware to process huge volumes of landing-sensor data,” said Butler. “This is an exciting time for us to be working on hardware that will enable NASA’s next giant leaps.”

Testing at JPL, which began in February, will continue for several months. Results have been promising: The processor is working as designed and indications show it operating at 500 times the performance of the radiation-hardened chips currently in use. In a symbolic milestone, the team sent an email at the start of testing with the subject line “Hello Universe” — a nod to the test message that was popular in early computer development.

Computing superpowers

Built by Microchip Technology Inc., headquartered in Chandler, Arizona, the High Performance Spaceflight Computing processor is being developed by the company and JPL through a commercial partnership. Samples have been provided to early access partners in the broader defense and commercial aerospace industry. The technology will enable autonomous spacecraft to use artificial intelligence to respond in real time to complex situations and environments where human input isn’t possible. It will help deep space missions analyze, store, and transmit troves of data to Earth, accelerating the rate of science discoveries. It could also support future human missions to the Moon and Mars.

Known as a system-on-a-chip (or SoC), the processor can fit in the palm of a hand and includes all the key components of a computer, such as central processing units, computational offloads, advanced networking units, memory, and input/output interfaces. Compact and energy-efficient, SoCs are commonly found in smartphones and tablets. But only the SoCs JPL is testing are built to survive for years, millions (or even billions) of miles from the nearest repair technician, enduring conditions that even the toughest home user couldn’t replicate. 

Once certified for spaceflight, NASA will incorporate the chip into the computing hardware for many of the agency’s Earth orbiters, rovers exploring planetary surfaces, crewed habitats, and deep-space missions. The technology will be adapted by Microchip for Earth-based industries too, such as aviation and automotive manufacturing. The versatility of High Performance Spaceflight Computing supports NASA’s continued advancements in space exploration while providing transformative tools for numerous fields on Earth. 

The project is managed by the Space Technology Mission Directorate’s Game Changing Development (GCD) program based at NASA Langley. The GCD program and JPL, a division of Caltech in Pasadena, California, led the end-to-end maturation of the High Performance Spaceflight Computing technology by developing mission requirements, funding industry studies, and guiding the project life cycle to delivery. NASA JPL selected Microchip as a partner in 2022, and the company funded its own research and development of the processor.

I Am Artemis: Kathleen Harmon

Listen to this audio excerpt from Kathleen Harmon, the Artemis II Mission Interface Manager for NASA’s Deep Space Network:

Captivated by Apollo launches on her television as a child, Kathleen Harmon now plays a key role in NASA’s Artemis program.

Harmon serves as the Artemis II mission interface manager for NASA’s Deep Space Network, an international array of giant radio antennas which are used to communicate with spacecraft. Managed by the agency’s Jet Propulsion Laboratory in Southern California, the Deep Space Network is the largest scientific telecommunications system in the world, supporting more than 40 missions exploring deep space. The network is also a key component of NASA’s Moon-bound Artemis missions.

“If you’re in a car and you’re going somewhere and you don’t have GPS or a cellphone, you might get lost, or you might not be able to tell someone that you’re lost,” said Harmon, illustrating how the Deep Space Network “talks” to spacecraft. “The network provides that lifeline to spacecraft across the solar system, and even interstellar space, so that they can talk to Earth and send back amazing science data, images, and videos from Mars rovers, space telescopes, orbiters, and more.”

In her role as a mission interface manager, and with her background as a systems engineer and decades of experience with NASA, Harmon prepares missions for launch and operations. This role requires careful coordination and collaboration across international partners, as the Deep Space Network’s radio antennas are spread around the world. She was responsible for ensuring the Deep Space Network was prepared to support the Artemis II spacecraft before launch.

You could not get any of that information back without the network. It’s a critical asset that also lets spacecraft know where they are.

“The network has three complexes equally spaced around the world so, as the Earth rotates, one is always in view to communicate with spacecraft wherever they are in the solar system,” said Harmon.

At any given moment, the Deep Space Network complex that is currently experiencing daylight is “in control” of the entire network to ensure consistent spacecraft connectivity, an operational approach the network team calls “follow the Sun.”

While the network supports NASA’s return to the Moon, working in partnership with the Near Space Network, it will continue to maintain a close watch on NASA’s fleet of spacecraft at the Moon and beyond.

“We supported Artemis II 24 hours a day, seven days a week for the entire mission with two antennas — a prime and a backup,” Harmon said. She added that while the network was supporting Artemis II, it also communicated with robotic rovers and spacecraft throughout the solar system.

While Harmon’s work has supported missions from Juno to Voyager, her contributions to the Artemis program remind her of what first inspired her to join to NASA.

“I was a very small child when the Apollo missions happened,” said Harmon. “Apollo was my earliest memory.”

Just thinking that I can be part of not only the Apollo generation but now also the Artemis generation — it’s very exciting to bridge that gap. This is a Golden Age of exploration.

New Ultra-Black Coating Could Enable the Search for Life on Exoplanets 

A recently developed ultra-black coating not only efficiently absorbs light, but is also extremely thin and durable, enabling its potential use on starshades that could someday support the imaging of exoplanets and potentially facilitate the detection of life beyond our solar system.

What is a Starshade and What Could it Do? 

The light emitted by a star can be billions of times brighter than the light reflected from its surrounding planets. This bright starlight makes it very difficult for a space telescope to image an exoplanet — it’s like trying to find the light reflected from a gnat that is flying near a spotlight. In addition, the light from our Sun scatters off spacecraft surfaces and back into the telescope, contributing even more light “pollution” that can easily obscure the dim light reflected from an exoplanet.  

A starshade is a giant, flower-shaped spacecraft (roughly half the size of a football field) that is designed to be positioned between a space telescope and a distant star so that it casts a shadow from the distant star onto the telescope. A starshade can block unwanted light from the parent star to the extent that less than one part per billion of the starlight is observable, while allowing the much fainter light from an orbiting exoplanet to pass around the starshade and reach the telescope, thereby enabling its detection. But to enable a telescope to distinguish an exoplanet, a starshade must create an extremely pristine shadow on the telescope. Not only must it block the starlight from the parent star, it must also suppress the stray light from our Sun that scatters from the starshade’s “petal” edges into the telescope. 

The Problem of Stray Sunlight 

Over the past decade, NASA-sponsored engineers have explored various methods to address the issue of stray sunlight. For example, they developed a way to make a starshade’s edges razor sharp by crafting blades from amorphous metals. The edges of these blades were only 300 nanometers thick, but data showed that even such thin metal edges would still scatter too much sunlight into the telescope.  

Researchers also tried applying black coatings to the starshade edges to reduce the reflected light. Unfortunately, the existing black coatings were far too thick; they made the starshade edges thicker (duller), which actually increased the scatter. Carbon nanotube coatings, for instance, are several microns thick — much thicker than the 300-nm starshade edge. Other existing coatings that rely on three-dimensional microstructures to trap light were also too thick. 

A New Kind of Black Coating 

In 2004, David Sheikh, founder of the small business ZeCoat Corporation, was researching the concept of a “black mirror” — a mirror that absorbs nearly all incident light instead of reflecting it. He came across a methodology used decades ago to make light-absorbing, smooth surfaces.  

Sheikh used modern computing techniques and more accurate material property data to improve this methodology, and developed a breakthrough method for manufacturing an ultra-black coating using a unique, motion-controlled, physical vapor deposition process also developed at ZeCoat. The coating design uses extremely thin, partially transparent metal layers that are separated by dielectric glass layers to form multiple light-absorbing, nanoscale cavities. When the thicknesses of the layers are tuned precisely with the aid of a computer, incoming light resonates as a standing wave inside the cavities, where the metals absorb it. The principle is similar to the Fabry–Perot cavity used in lasers — except instead of amplifying light, the light is trapped and absorbed. This new coating turned out to be 100 times thinner than those previously tested for use on starshades. 

In 2020, NASA’s Exoplanet Exploration Program at the agency’s Jet Propulsion Laboratory (JPL) in Southern California chartered a Starshade Science and Industry Partnership (SIP) to maximize the technology readiness level of starshades to enable potential future exoplanet science missions. As part of this initiative, the new coating developed by Zecoat was applied to prototype starshade edges, and engineers at JPL used a custom-built laser scatterometer to measure scatter from coated and uncoated 50-cm long amorphous metal blades. These tests demonstrated that the new coating reduced the reflected light by a factor of about 20 — enough to enable a telescope to image an exoplanet. (The results of this effort were published here in the SPIE digital Library).

Beyond the Edge: Coating Starshade Membranes 

Building on the success of the edge coating demonstration and supported by a 2021 NASA Small Business Innovative Research (SBIR) contract, ZeCoat developed a novel thin film deposition process to coat large sheets of polyimide film with a similar ultra-black finish. The process uses multiple electron beam evaporators to apply thin, uniform films to a moving membrane substrate in a roll-to-roll coating process. These large coated membranes (~ 1-meter wide and many meters long) could be patched together to form a starshade’s central disk section, as well as its petal surfaces, which would remove even more stray light and further improve the quality of images a space telescope could produce. (For additional details, see the entry for this project on NASA TechPort and this article in the SPIE digital Library.) 

Additional Applications 

Besides use on starshades, durable black coatings have a wide variety of science, military, and commercial applications. For example, they could be used to darken constellations of satellites so they are less visible from the ground, or to darken surfaces near the camera on a cell phone.   

In addition, ZeCoat recently was awarded a NASA SBIR Phase I contract and is applying the thin-film roll-to-roll coating process described above to develop thermal control coatings that are resilient enough to mitigate damage from micrometeorite strikes. These coatings could be potentially used on future space vehicles such as the Habitable Worlds Observatory.

For additional details, see the entry for this project on NASA TechPort.

Australia’s Cloudy Beauty

It’s autumn in the Southern Hemisphere, which means it’s fog season in the Victorian Alps. NASA’s Terra satellite captured this view of morning fog filling valleys in several national parks across the mountains of eastern Victoria in May.  

As nights lengthen with the season, the atmosphere has more time to cool and approach the dew point—the temperature at which the air becomes saturated and water vapor can condense into radiation fog. Because cold air is denser than warm air, it sinks and drains into valleys, allowing fog to develop there first. In low-elevation areas, radiation fog usually fades as the Sun warms the ground, but it tends to linger in mountain valleys because they remain shaded longer. On this day, geostationary satellite imagery shows the fog persisting for about two hours.

Fog is a low-lying type of cloud composed of tiny water droplets suspended in the air. The main difference between a cloud and fog is that the base of fog reaches the ground, while the base of a cloud is generally well above the surface. Radiation fog forms in clear, calm conditions at night. In this case, a blast of cold, soggy weather primed the region by moistening land surfaces a few days prior to the arrival of a slow-moving high that brought calmer, warmer conditions that were conducive to fog formation. 

Many valleys in the mountains also have rivers, streams, and lakes, which amplified the process by providing a ready supply of water vapor. In the image above, zones of fog have formed along several water bodies, including the Mitta Mitta River, Buffalo River, Livingston Creek, Lake Dartmouth, and Snowy River.  

The same conditions fueled another noteworthy cloud a few hundred kilometers to the southwest. At about 8:19 a.m. local time (22:19 Universal Time), the Terra satellite captured an arch-shaped cloud over Port Phillip Bay, roughly stretching from St. Leonards on the bay’s western shore to Mount Eliza on the eastern side.

The feature likely formed as converging land and sea breezes interacted with the horseshoe-shaped terrain that defines the bay. Geostationary satellite imagery shows the arch-shaped cloud moving southward across the bay as the valley fog to the northeast faded.

Curiosity Blog, Sols 4886-4892: Ingenuity and Perseverance, Curiosity Style

Written by Michelle Minitti, MAHLI Deputy Principal Investigator

Earth planning date: Friday, May 8, 2026

While we know the monikers Ingenuity and Perseverance are attached to our sister helicopter and rover on the Mars 2020 mission, those characteristics were in full force with Curiosity over the past week. The science we achieved this week was enabled by the ingenuity of the Curiosity engineers and scientists manifested in this extraordinary time lapse. It demonstrates the careful dance of arm motions employed — each one diligently planned by the team — to free Curiosity’s drill from the “Atacama” target. Watch the arm twist, bend, and turn with a rock slab attached, and be amazed. 

The highest-priority activities after liberating the drill included imaging the drill with Mastcam and ChemCam RMI, and imaging into the now-empty drill hole with MAHLI (the image above). The science team made the most of the freshly-broken surfaces created when Atacama fell back to Mars, and the freshly-exposed sand once hidden underneath Atacama. ChemCam targeted one of the clean fracture faces with two LIBS rasters at “Tamarugal” and “Tamarugo,” and followed with another raster on a light-toned patch of bedrock formerly under Atacama at “Colchane.”  MAHLI and APXS analyzed sand near Colchane at the target “Yerba Loca.” Beyond Atacama, Mastcam and ChemCam imaged the large buttes towering above our current and future drive paths. Mastcam also imaged two exposures of the polygonal fractures present in this area (targets “Cerro Elefantes” and “Azul Pampa”) and looked for wind-induced changes in the sand (“Playa los Metales”). ChemCam planned a passive spectroscopy observation of light-toned features on the “Paniri” butte and checked out a potential meteorite with a LIBS raster at “Isla Mocha.”  

As engineering assessments continued, Curiosity drove uphill to study a contact between two different rock types, which can indicate a change in formation conditions, a break in time, or both. MAHLI, APXS, and ChemCam teamed up to study both rock types at the lighter-toned, layered “Toro” target and the darker, flaky “Inca de Oro” target. Mastcam planned multiple mosaics capturing different structures and transitions exposed along the contact. Across the plans during the week, REMS, RAD, and DAN regularly measured the environment above and below the rover, and Navcam and Mastcam teamed up to look for clouds, dust devils, and dust in the atmosphere.

With the health of the drill and arm confirmed by the engineers, Curiosity exhibited perseverance by heading toward a new workspace with a promising (larger) block for a new drill attempt. Our Martian exploration continues undaunted.
