NASA announced 10 winning teams for its latest TechLeap Prize — the Space Technology Payload Challenge — on June 26. The winners emerged from a record-breaking field of more than 200 applicants to earn cash prizes worth up to $500,000, if they have a flight-ready unit. Recipients may also have the opportunity to flight test their technologies.
NASA’s Biological and Physical Sciences (BPS) division is supporting the emerging space economy through challenges like TechLeap. The projects receive funding through the Commercially Enabled Rapid Space Science (CERISS) initiative, which pairs government research goals with commercial innovation.
Two awardees’ capabilities specifically address BPS research priorities, which include conducting investigations that inform future space crops and advance precision health.
Ambrosia Space Manufacturing Corporation is developing a centrifuge system to separate nutrients from cell cultures — potentially creating space-based food processing that could turn algae into digestible meals for astronauts.
Helogen Corporation is building an automated laboratory system that can run biological experiments without requiring astronaut involvement and may be able to transmit real-time data to researchers on Earth without having to wait for physical samples to return.
“The innovations of these small- and midsize businesses could enable NASA to accelerate the pace of critical research,” says Dan Walsh, BPS’s program executive for CERISS. “It’s also an example of NASA enabling the emerging space industry to grow and thrive beyond big corporations.”
Small Packages with Big Ambitions
Every inch and ounce counts on a spacecraft, which means the winning teams have to think small while solving big problems.
Commercial companies play a pivotal role in enabling space-based research — they bring fresh approaches to ongoing challenges. But space missions demand a different kind of innovation, and TechLeap teams face both time and size constraints for their experiments.
Winners have six to nine months to demonstrate that their concepts work. That’s a significant contrast from traditional space technology development, which can stretch for years.
The research serves a larger purpose as well. The technology helps NASA “know before we go” on longer, deep-space missions to the Moon and Mars. Understanding how technologies behave in microgravity or extreme environments can prevent costly failures when astronauts are far from Earth.
Small investments in proof-of-concept technologies can bring in a high ROI. With the TechLeap Prize, BPS is betting that big ideas will come in small packages.

As an administrative assistant in the Safety and Mission Assurance Office at NASA’s White Sands Test Facility in Las Cruces, New Mexico, Juliana Barajas approaches her work with one clear mission: to help others succeed.
Juliana Barajas stands in front of the Super Guppy at the El Paso Forwarding Operations Location (EPFOL) in El Paso, Texas. Being courteous, helpful, resourceful, and always willing to learn new things is what led me to NASA.
Juliana Barajas
Administrative Assistant
For over two decades, she has supported NASA’s mission with a career grounded in service, perseverance, and gratitude. Whether coordinating tasks, solving problems, or lending a listening ear, Barajas plays a vital role in helping her team maintain safety and excellence.
“When I was young, I never imagined working at NASA,” said Barajas “I dreamed of studying mechanical engineering but never got the opportunity.”
Instead, she pursued a degree in computer secretarial studies. “I am grateful for the opportunity to prove I could do just about any job given to me,” she said.
Juliana Barajas received a Secretarial Excellence Award in 2009 at NASA’s Johnson Space Center in Houston. In 2009, Barajas earned the Secretarial Excellence Award, a recognition she calls a highlight of her career. But for Barajas, pride is not reserved for big moments alone. “I take pride in everything I do every day,” she said. “If I can help those around me succeed, then I have fulfilled my duty.”
Her career has also taught her invaluable personal lessons. “I’ve learned to be a good listener and to be myself,” she said. “I’ve also learned to be resourceful and to not give up. I am grateful for having wonderful people around me who don’t look down on me when I reach out for answers.”

Scientists predict one of the major surveys by NASA’s upcoming Nancy Grace Roman Space Telescope may reveal around 100,000 celestial blasts, ranging from exploding stars to feeding black holes. Roman may even find evidence of some of the universe’s first stars, which are thought to completely self-destruct without leaving any remnant behind.
This simulation showcases the dynamic universe as NASA’s Nancy Grace Roman Space Telescope could see it over the course of its five-year primary mission. The video sparkles with synthetic supernovae from observations of the OpenUniverse simulated universe taken every five days (similar to the expected cadence of Roman’s High-Latitude Time-Domain Survey, which OpenUniverse simulates in its entirety). On top of the static sky of stars in the Milky Way and other galaxies, more than a million exploding stars flare into visibility and then slowly fade away. To highlight the dynamic physics happening and for visibility at this scale, the true brightness of each transient event has been magnified by a factor of 10,000 and no background light has been added to the simulated images. The video begins with Roman’s full field of view, which represents a single pointing of Roman’s camera, and then zooms into one square.Credit: NASA’s Goddard Space Flight Center and M. Troxel Cosmic explosions offer clues to some of the biggest mysteries of the universe. One is the nature of dark energy, the mysterious pressure thought to be accelerating the universe’s expansion.
“Whether you want to explore dark energy, dying stars, galactic powerhouses, or probably even entirely new things we’ve never seen before, this survey will be a gold mine,” said Benjamin Rose, an assistant professor at Baylor University in Waco, Texas, who led a study about the results. The paper is published in The Astrophysical Journal.
Called the High-Latitude Time-Domain Survey, this observation program will scan the same large region of the cosmos every five days for two years. Scientists will stitch these observations together to create movies that uncover all sorts of cosmic fireworks.
Chief among them are exploding stars. The survey is largely geared toward finding a special class of supernova called type Ia. These stellar cataclysms allow scientists to measure cosmic distances and trace the universe’s expansion because they peak at about the same intrinsic brightness. Figuring out how fast the universe has ballooned during different cosmic epochs offers clues to dark energy.
This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA’s new James Webb Space Telescope, this image reveals for the first time previously invisible areas of star birth.Credit: NASA, ESA, CSA, and STScI In the new study, scientists simulated Roman’s entire High-Latitude Time-Domain Survey. The results suggest Roman could see around 27,000 type Ia supernovae—about 10 times more than all previous surveys combined.
Beyond dramatically increasing our total sample of these supernovae, Roman will push the boundaries of how far back in time we can see them. While most of those detected so far occurred within approximately the last 8 billion years, Roman is expected to see vast numbers of them earlier in the universe’s history, including more than a thousand that exploded more than 10 billion years ago and potentially dozens from as far back as 11.5 billion years. That means Roman will almost certainly set a new record for the farthest type Ia supernova while profoundly expanding our view of the early universe and filling in a critical gap in our understanding of how the cosmos has evolved over time.
“Filling these data gaps could also fill in gaps in our understanding of dark energy,” Rose said. “Evidence is mounting that dark energy has changed over time, and Roman will help us understand that change by exploring cosmic history in ways other telescopes can’t.”
But type Ia supernovae will be hidden among a much bigger sample of exploding stars Roman will see once it begins science operations in 2027. The team estimates Roman will also spot about 60,000 core-collapse supernovae, which occur when a massive star runs out of fuel and collapses under its own weight.
That’s different from type Ia supernovae, which originate from binary star systems that contain at least one white dwarf — the small, hot core remnant of a Sun-like star — siphoning material from a companion star. Core-collapse supernovae aren’t as useful for dark energy studies as type Ias are, but their signals look similar from halfway across the cosmos.
“By seeing the way an object’s light changes over time and splitting it into spectra — individual colors with patterns that reveal information about the object that emitted the light—we can distinguish between all the different types of flashes Roman will see,” said Rebekah Hounsell, an assistant research scientist at the University of Maryland-Baltimore County working at NASA’s Goddard Space Flight Center in Greenbelt, Maryland and a co-author of the study.
“With the dataset we’ve created, scientists can train machine-learning algorithms to distinguish between different types of objects and sift through Roman’s downpour of data to find them,” Hounsell added. “While searching for type Ia supernovae, Roman is going to collect a lot of cosmic ‘bycatch’—other phenomena that aren’t useful to some scientists, but will be invaluable to others.”
Hidden Gems
Thanks to Roman’s large, deep view of space, scientists say the survey should also unearth extremely rare and elusive phenomena, including even scarcer stellar explosions and disintegrating stars.
Upon close approach to a black hole, intense gravity can shred a star in a so-called tidal disruption event. The stellar crumbs heat up as they swirl around the black hole, creating a glow astronomers can see from across vast stretches of space-time. Scientists think Roman’s survey will unveil 40 tidal disruption events, offering a chance to learn more about black hole physics.
The team also estimates Roman will find about 90 superluminous supernovae, which can be 100 times brighter than a typical supernova. They pack a punch, but scientists aren’t completely sure why. Finding more of them will help astronomers weigh different theories.
Even rarer and more powerful, Roman could also detect several kilonovae. These blasts occur when two neutron stars — extremely dense cores leftover from stars that exploded as supernovae — collide. To date, there has been only one definitive kilonova detection. The team estimates Roman could spot five more.
NASA’s Roman Space Telescope will survey the same areas of the sky every few days following its launch in May 2027. Researchers will mine these data to identify kilonovae – explosions that happen when two neutron stars or a neutron star and a black hole collide and merge. When these collisions happen, a fraction of the resulting debris is ejected as jets, which move near the speed of light. The remaining debris produces hot, glowing, neutron-rich clouds that forge heavy elements, like gold and platinum. Roman’s extensive data will help astronomers better identify how often these events occur, how much energy they give off, and how near or far they are.Credit: NASA, ESA, J. Olmsted (STScI) That would help astronomers learn much more about these mysterious events, potentially including their fate. As of now, scientists are unsure whether kilonovae result in a single neutron star, a black hole, or something else entirely.
Roman may even spot the detonations of some of the first stars that formed in the universe. These nuclear furnaces were giants, up to hundreds of times more massive than our Sun, and unsullied by heavy elements that hadn’t yet formed.
They were so massive that scientists think they exploded differently than modern massive stars do. Instead of reaching the point where a heavy star today would collapse, intense gamma rays inside the first stars may have turned into matter-antimatter pairs (electrons and positrons). That would drain the pressure holding the stars up until they collapsed, self-destructing in explosions so powerful they’re thought to leave nothing behind.
So far, astronomers have found about half a dozen candidates of these “pair-instability” supernovae, but none have been confirmed.
“I think Roman will make the first confirmed detection of a pair-instability supernova,” Rose said — in fact the study suggests Roman will find more than 10. “They’re incredibly far away and very rare, so you need a telescope that can survey a lot of the sky at a deep exposure level in near-infrared light, and that’s Roman.”
A future rendition of the simulation could include even more types of cosmic flashes, such as variable stars and active galaxies. Other telescopes may follow up on the rare phenomena and objects Roman discovers to view them in different wavelengths of light to study them in more detail.
“Roman’s going to find a whole bunch of weird and wonderful things out in space, including some we haven’t even thought of yet,” Hounsell said. “We’re definitely expecting the unexpected.”

Curiosity Blog, Sols 4584 – 4585: Just a Small Bump
NASA’s Mars rover Curiosity acquired this image using its Left Navigation Camera on June 27, 2025 — Sol 4582, or Martian day 4,582 of the Mars Science Laboratory mission — at 05:28:57 UTC. NASA/JPL-Caltech Written by Abigail Fraeman, Deputy Project Scientist at NASA’s Jet Propulsion Laboratory
Earth planning date: Friday, June 27, 2025
We weren’t able to unstow Curiosity’s robotic arm on Wednesday because of some potentially unstable rocks under Curiosity’s wheels, but we liked the rocks at Wednesday’s location enough that we decided to spend a sol repositioning the rover so that we’d have another chance today to analyze them. The small adjustment of the rover’s position, or “bump,” as we like to call it during tactical planning, was successful, and we found ourselves in a nice stable pose this morning which allowed us to use our highly capable robotic arm to observe the rocks in front of us.
We will be collecting APXS and MAHLI observations of two targets today. The first, “Santa Elena,” is the bumpy rock that caught our eye on Wednesday. The second, informally named “Estancia Allkamari,” is a patch of nearby sand. We’ll analyze this target to understand if and how the sand composition has changed as we’ve driven across Mount Sharp, and to better help us understand how sand may be contributing to future compositional measurements that cover mixtures of sand and rock. MAHLI and ChemCam will team up to observe a third target named “Ticatica,” which is another bumpy rock nearby that looks like it might have a dark patch on its side.
This is the final weekend of this Martian year when temperature and relative humidity in Gale crater hit the sweet spot where conditions are right for frost to form in the pre-dawn hours. We’re taking this last opportunity to see if we can catch any evidence of frost with the ChemCam laser, shooting a sandy (and hopefully cold) portion of the ground in the pre-dawn hours on a target named “Rio Huasco.” Other activities in the plan include atmospheric monitoring, Mastcam mosaics, including a 20 x 3 mosaic of the large boxwork structures in the distance, and a short drive to the southwest to check out a rocky raised ridge.

Hubble Studies Small but Mighty Galaxy
This NASA/ESA Hubble Space Telescope features the nearby galaxy NGC 4449. ESA/Hubble & NASA, E. Sabbi, D. Calzetti, A. Aloisi This portrait from the NASA/ESA Hubble Space Telescope puts the nearby galaxy NGC 4449 in the spotlight. The galaxy is situated just 12.5 million light-years away in the constellation Canes Venatici (the Hunting Dogs). It is a member of the M94 galaxy group, which is near the Local Group of galaxies that the Milky Way is part of.
NGC 4449 is a dwarf galaxy, which means that it is far smaller and contains fewer stars than the Milky Way. But don’t let its small size fool you — NGC 4449 packs a punch when it comes to making stars! This galaxy is currently forming new stars at a much faster rate than expected for its size, which makes it a starburst galaxy. Most starburst galaxies churn out stars mainly in their centers, but NGC 4449 is alight with brilliant young stars throughout. Researchers believe that this global burst of star formation came about because of NGC 4449’s interactions with its galactic neighbors. Because NGC 4449 is so close, it provides an excellent opportunity for Hubble to study how interactions between galaxies can influence the formation of new stars.
Hubble released an image of NGC 4449 in 2007. This new version incorporates several additional wavelengths of light that Hubble collected for multiple observing programs. These programs encompass an incredible range of science, from a deep dive into NGC 4449’s star-formation history to the mapping of the brightest, hottest, and most massive stars in more than two dozen nearby galaxies.
The NASA/ESA/CSA James Webb Space Telescope has also observed NGC 4449, revealing in intricate detail the galaxy’s tendrils of dusty gas, glowing from the intense starlight radiated by the flourishing young stars.
