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.

Our Beautiful Water World
This Jan. 30, 2012 image of Earth was created from photographs taken by the Visible/Infrared Imager Radiometer Suite (VIIRS) instrument aboard the Suomi NPP satellite. Many features of North America and the Western Hemisphere are particularly visible. The composite was created from the data collected during four orbits of the robotic satellite taken earlier in January 2012 and digitally projected onto the globe.
VIIRS collects visible and infrared imagery along with global observations of Earth’s land, atmosphere, cryosphere, and ocean, extending observational records collected by similar instruments aboard previously launched satellites, such as NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) and NOAA’s Advanced Very High Resolution Radiometer (AVHRR).

Six mind-blowing facts about Galileo
Did you know Galileo was born in the Netherlands in the 1990s? Europe’s own global navigation satellite system was developed in ESA’s technological heart, ESTEC, in Noordwijk, almost three decades ago. Since then, it has grown to become one of the most complex and critical infrastructures ever built in Europe, as well as the largest European satellite constellation and ground segment.

A tool developed at NASA’s Advanced Supercomputing division provides researchers with a global view of their ocean simulation in high resolution. In this part of the global visualization, the Gulf Stream features prominently. Surface water speeds are shown ranging from 0 meters per second (dark blue) to 1.25 meters (about 4 feet) per second (cyan). The video is running at one simulation day per second. The data used comes from the Estimating the Circulation and Climate of the Ocean (ECCO) consortium. Credits: NASA/Bron Nelson, David Ellsworth“Every time I help with visualizing [ocean] simulation data, I learn about an entirely new area of ocean or climate research, and I’m reminded of how vast and rich this area of research is. And…the real magic happens at the intersection and interaction of simulated and observed data.
It is a great honor – and a thrill – to collaborate with devoted, world-class scientists doing such important, cutting-edge research and sometimes to even help them learn something new about their science.”

Why is Methane Seeping on Mars? NASA Scientists Have New Ideas
Maksym Bocharov
The most surprising revelation from NASA’s Curiosity Mars Rover — that methane is seeping from the surface of Gale Crater — has scientists scratching their heads.
Living creatures produce most of the methane on Earth. But scientists haven’t found convincing signs of current or ancient life on Mars, and thus didn’t expect to find methane there. Yet, the portable chemistry lab aboard Curiosity, known as SAM, or Sample Analysis at Mars, has continually sniffed out traces of the gas near the surface of Gale Crater, the only place on the surface of Mars where methane has been detected thus far. Its likely source, scientists assume, are geological mechanisms that involve water and rocks deep underground.
If that were the whole story, things would be easy. However, SAM has found that methane behaves in unexpected ways in Gale Crater. It appears at night and disappears during the day. It fluctuates seasonally, and sometimes spikes to levels 40 times higher than usual. Surprisingly, the methane also isn’t accumulating in the atmosphere: ESA’s (the European Space Agency) ExoMars Trace Gas Orbiter, sent to Mars specifically to study the gas in the atmosphere, has detected no methane.
Why do some science instruments detect methane on the Red Planet while others don’t?
“It’s a story with a lot of plot twists,” said Ashwin Vasavada, Curiosity’s project scientist at NASA’s Jet Propulsion Laboratory in Southern California, which leads Curiosity’s mission.
Methane keeps Mars scientists busy with lab work and computer modeling projects that aim to explain why the gas behaves strangely and is detected only in Gale Crater. A NASA research group recently shared an interesting proposal.
Reporting in a March paper in the Journal of Geophysical Research: Planets, the group suggested that methane — no matter how it’s produced — could be sealed under solidified salt that might form in Martian regolith, which is “soil” made of broken rock and dust. When temperature rises during warmer seasons or times of day, weakening the seal, the methane could seep out.
Led by Alexander Pavlov, a planetary scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the researchers suggest the gas also can erupt in puffs when seals crack under the pressure of, say, a rover the size of a small SUV driving over it. The team’s hypothesis may help explain why methane is detected only in Gale Crater, Pavlov said, given that’s it’s one of two places on Mars where a robot is roving and drilling the surface. (The other is Jezero Crater, where NASA’s Perseverance rover is working, though that rover doesn’t have a methane-detecting instrument.)
Pavlov traces the origin of this hypothesis to an unrelated experiment he led in 2017, which involved growing microorganisms in a simulated Martian permafrost (frozen soil) infused with salt, as much of Martian permafrost is.
Pavlov and his colleagues tested whether bacteria known as halophiles, which live in saltwater lakes and other salt-rich environments on Earth, could thrive in similar conditions on Mars.
The microbe-growing results proved inconclusive, he said, but the researchers noticed something unexpected: The top layer of soil formed a salt crust as salty ice sublimated, turning from a solid to a gas and leaving the salt behind.
Permafrost on Mars and Earth
“We didn’t think much of it at the moment,” Pavlov said, but he remembered the soil crust in 2019, when SAM’s tunable laser spectrometer detected a methane burst no one could explain.
“That’s when it clicked in my mind,” Pavlov said. And that’s when he and a team began testing the conditions that could form and crack hardened salt seals.
Pavlov’s team tested five samples of permafrost infused with varying concentrations of a salt called perchlorate that’s widespread on Mars. (There’s likely no permafrost in Gale Crater today, but the seals could have formed long ago when Gale was colder and icier.) The scientists exposed each sample to different temperatures and air pressure inside a Mars simulation chamber at NASA Goddard.
Periodically, Pavlov’s team injected neon, a methane analog, underneath the soil sample and measured the gas pressure below and above it. Higher pressure beneath the sample implied the gas was trapped. Ultimately, a seal formed under Mars-like conditions within three to 13 days only in samples with 5% to 10% perchlorate concentration.
This is a sample of mock Martian regolith, which is “soil” made of broken rock and dust. It’s one of five samples that scientists infused with varying concentrations of a salt called perchlorate that’s widespread on Mars. They exposed each sample to Mars-like conditions in the Mars simulation chamber at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. The brittle clumps in the sample above show that a seal of salt did not form in this sample because the concentration of salt was too low. NASA/Alexander Pavlov This image is of another sample of mock Martian “soil” after it was removed from the Mars simulation chamber. The surface is sealed with a solid crust of salt. Alexander Pavlov and his team found that a seal formed after a sample spent three to 13 days under Mars-like conditions, and only if it had 5% to 10% perchlorate salt concentration. The color is lighter in the center where the sample was scratched with a metal pick. The light color indicates a drier soil underneath the top layer, which absorbed moisture from the air as soon as the sample was removed from the simulation chamber, turning brown. NASA/Alexander PavlovThat’s a much higher salt concentration than Curiosity has measured in Gale Crater. But regolith there is rich in a different type of salt minerals called sulfates, which Pavlov’s team wants to test next to see if they can also form seals.
Curiosity rover has arrived at a region believed to have formed as Mars’ climate was drying.
Improving our understanding of methane generation and destruction processes on Mars is a key recommendation from the 2022 NASA Planetary Mission Senior Review, and theoretical work like Pavlov’s is critical to this effort. However, scientists say they also need more consistent methane measurements.
SAM sniffs for methane only several times a year because it is otherwise busy doing its primary job of drilling samples from the surface and analyzing their chemical makeup.
In 2018, NASA announced that the Sample Analysis at Mars chemistry lab aboard the Curiosity Rover discovered ancient organic molecules that had been preserved in rocks for billions of years. Findings like this one help scientists understand the habitability of early Mars and pave the way for future missions to the Red Planet.Credit: NASA’s Goddard Space Flight Center

“Methane experiments are resource intensive, so we have to be very strategic when we decide to do them,” said Goddard’s Charles Malespin, principal investigator for SAM.
Yet, to test how often methane levels spike, for instance, would require a new generation of surface instruments that measure methane continuously from many locations across Mars, scientists say.
“Some of the methane work will have to be left to future surface spacecraft that are more focused on answering these specific questions,” Vasavada said.
