Hubble Captures Young Stars Changing Their Environments
This NASA/ESA Hubble Space Telescope image features the nearest star-forming region to Earth, the Orion Nebula (Messier 42, M42), located some 1,500 light-years away. ESA/Hubble, NASA, and T. Megeath This NASA/ESA Hubble Space Telescope image peers into the dusty recesses of the nearest massive star-forming region to Earth, the Orion Nebula (Messier 42, M42). Just 1,500 light-years away, the Orion Nebula is visible to the unaided eye below the three stars that form the ‘belt’ in the constellation Orion. The nebula is home to hundreds of newborn stars including the subject of this image: the protostars HOPS 150 and HOPS 153.
These protostars get their names from the Herschel Orion Protostar Survey, conducted with ESA’s Herschel Space Observatory. The object visible in the upper-right corner of this image is HOPS 150: it’s a binary star system where two young protostars orbit each other. Each star has a small, dusty disk of material surrounding it. These stars gather material from their respective dust disks, growing in the process. The dark line that cuts across the bright glow of these protostars is a cloud of gas and dust falling in on the pair of protostars. It is over 2,000 times wider than the distance between Earth and the Sun. Based on the amount of infrared light HOPS 150 is emitting, as compared to other wavelengths it emits, the protostars are mid-way down the path to becoming mature stars.
Extending across the left side of the image is a narrow, colorful outflow called a jet. This jet comes from the nearby protostar HOPS 153, which is out of the frame. HOPS 153 is significantly younger than its neighbor. That stellar object is still deeply embedded in its birth nebula and enshrouded by a cloud of cold, dense gas. While Hubble cannot penetrate this gas to see the protostar, the jet HOPS 153 emitted is brightly and clearly visible as it plows into the surrounding gas and dust of the Orion Nebula.
The transition from tightly swaddled protostar to fully fledged star will dramatically affect HOPS 153’s surroundings. As gas falls onto the protostar, its jets spew material and energy into interstellar space, carving out bubbles and heating the gas. By stirring up and warming nearby gas, HOPS 153 may regulate the formation of new stars in its neighborhood and even slow its own growth.

A collage of artist concepts highlighting the novel approaches proposed by the 2025 NIAC awardees for possible future missions.Credit: NASA/Left to Right: Saurabh Vilekar, Marco Quadrelli, Selim Shahriar, Gyula Greschik, Martin Bermudez, Ryan Weed, Ben Hockman, Robert Hinshaw, Christine Gregg, Ryan Benson, Michael Hecht NASA selected 15 visionary ideas for its NIAC (NASA Innovative Advanced Concepts) program which develops concepts to transform future missions for the benefit of all. Chosen from companies and institutions across the United States, the 2025 Phase I awardees represent a wide range of aerospace concepts.
The NIAC program nurtures innovation by funding early-stage technology concept studies for future consideration and potential commercialization. The combined award for the 2025 concepts is a maximum of $2.625M in grants to evaluate technologies that could enable future aerospace missions.
“Our next steps and giant leaps rely on innovation, and the concepts born from NIAC can radically change how we explore deep space, work in low Earth orbit, and protect our home planet” said Clayton Turner, associate administrator for NASA’s Space Technology Mission Directorate in Washington. “From developing small robots that could swim through the oceans of other worlds to growing space habitats from fungi, this program continues to change the possible.”
The newly selected concepts include feasibility studies to explore the Sun’s influence on our solar system, build sustainable lunar habitats from glass, explore Saturn’s icy moon, and more. All NIAC studies are in the early stages of conceptual development and are not considered official NASA missions.
Ryan Weed, Helicity Space LLC in Pasadena, California, proposes a constellation of spacecraft powered by the Helicity Drive, a compact and scalable fusion propulsion system, that could enable rapid, multi-directional exploration of the heliosphere and beyond, providing unprecedented insights on how the Sun interacts with our solar system and interstellar space. Demonstrating the feasibility of fusion propulsion could also benefit deep space exploration including crewed missions to Mars.
Martin Bermudez, Skyeports LLC in Sacramento, California, presents the concept of constructing a large-scale, lunar glass habitat in a low-gravity environment. Nicknamed LUNGS (Lunar Glass Structure), this approach involves melting lunar glass compounds to create a large spherical shell structure. This idea offers a promising solution for establishing self-sustaining, large-scale habitats on the lunar surface.
Justin Yim, University of Illinois in Urbana, proposes a jumping robot appropriately named LEAP (Legged Exploration Across the Plume), as a novel robotic sampling concept to explore Enceladus, a small, icy moon of Saturn that’s covered in geysers, or jets. The LEAP robots could enable collection of pristine, ocean-derived material directly from Enceladus’s jets and measurement of particle properties across multiple jets by traveling from one to another.
“All advancements begin as an idea. The NIAC program allows NASA to invest in unique ideas enabling innovation and supporting the nation’s aerospace economy,” said John Nelson, program executive for NASA’s Innovative Advanced Concepts in Washington.
The NIAC researchers, known as fellows, will investigate the fundamental premise of their concepts, identify potential challenges, and look for opportunities to bring these concepts to life.
In addition to the projects mentioned above, the following selectees received 2025 NIAC Phase I grants:
Michael Hecht, Massachusetts Institute of Technology, Cambridge: EVE (Exploring Venus with Electrolysis) Selim Shahriar, Northwestern University, Evanston, Illinois: SUPREME-QG: Space-borne Ultra-Precise Measurement of the Equivalence Principle Signature of Quantum Gravity Phillip Ansell, University of Illinois, Urbana: Hy2PASS (Hydrogen Hybrid Power for Aviation Sustainable Systems) Ryan Benson, ThinkOrbital Inc., Boulder, Colorado: Construction Assembly Destination Gyula Greschik, Tentguild Engineering Co, Boulder, Colorado: The Ribbon: Structure Free Sail for Solar Polar Observation Marco Quadrelli, NASA’s Jet Propulsion Laboratory in California’s Silicon Valley: PULSAR: Planetary pULSe-tAkeRv Ben Hockman, NASA’s Jet Propulsion Laboratory in California’s Silicon Valley: TOBIAS: Tethered Observatory for Balloon-based Imaging and Atmospheric Sampling Kimberly Weaver, NASA’s Goddard Space Flight Center in Greenbelt, Maryland: Beholding Black Hole Power with the Accretion Explorer Interferometer John Mather NASA’s Goddard Space Flight Center in Greenbelt, Maryland: Inflatable Starshade for Earthlike Exoplanets Robert Hinshaw, NASA’s Ames Research Center in Moffett Field, California: MitoMars: Targeted Mitochondria Replacement Therapy to Boost Deep Space Endurance Christine Gregg, NASA’s Ames Research Center in Moffett Field, California: Dynamically Stable Large Space Structures via Architected Metamaterials Saurabh Vilekar, Precision Combustion, North Haven, Connecticut: Thermo-Photo-Catalysis of Water for Crewed Mars Transit Spacecraft Oxygen Supply NASA’s Space Technology Mission Directorate funds the NIAC program, as it is responsible for developing the agency’s new cross-cutting technologies and capabilities to achieve its current and future missions.

5 Min Read NASA and Italian Space Agency Test Future Lunar Navigation Technology
The potentially record-breaking Lunar GNSS Receiver Experiment (LuGRE) payload will be the first known demonstration of GNSS signal reception on and around the lunar surface. Credits: NASA/Dave Ryan As NASA celebrates 55 years since the historic Apollo 11 crewed lunar landing, the agency also is preparing new navigation and positioning technology for the Artemis campaign, the agency’s modern lunar exploration program.
A technology demonstration helping pave the way for these developments is the Lunar GNSS Receiver Experiment (LuGRE) payload, a joint effort between NASA and the Italian Space Agency to demonstrate the viability of using existing GNSS (Global Navigation Satellite System) signals for positioning, navigation, and timing on the Moon.
During its voyage on an upcoming delivery to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative, LuGRE would demonstrate acquiring and tracking signals from both the U.S. GPS and European Union Galileo GNSS constellations during transit to the Moon, during lunar orbit, and finally for up to two weeks on the lunar surface itself.
The Lunar GNSS Receiver Experiment (LuGRE) will investigate whether signals from two Global Navigation Satellite System (GNSS) constellations, the U.S. Global Positioning System (GPS) and European Union’s Galileo, can be tracked at the Moon and used for positioning, navigation, and timing (PNT). The LuGRE payload is one of the first demonstrations of GNSS signal reception and navigation on and around the lunar surface, an important milestone for how lunar missions will access navigation and positioning technology. If successful, LuGRE would demonstrate that spacecraft can use signals from existing GNSS satellites at lunar distances, reducing their reliance on ground-based stations on the Earth for lunar navigation.
Today, GNSS constellations support essential services like navigation, banking, power grid synchronization, cellular networks, and telecommunications. Near-Earth space missions use these signals in flight to determine critical operational information like location, velocity, and time.
NASA and the Italian Space Agency want to expand the boundaries of GNSS use cases. In 2019, the Magnetospheric Multiscale (MMS) mission broke the world record for farthest GPS signal acquisition 116,300 miles from the Earth’s surface — nearly half of the 238,900 miles between Earth and the Moon. Now, LuGRE could double that distance.
“GPS makes our lives safer and more viable here on Earth,” said Kevin Coggins, NASA deputy associate administrator and SCaN (Space Communications and Navigation) Program manager at NASA Headquarters in Washington. “As we seek to extend humanity beyond our home planet, LuGRE should confirm that this extraordinary technology can do the same for us on the Moon.”
NASA, Firefly, Qascom, and Italian Space Agency team members examine LuGRE hardware in a clean room.Firefly Aerospace Reliable space communication and navigation systems play a vital role in all NASA missions, providing crucial connections from space to Earth for crewed and uncrewed missions alike. Using a blend of government and commercial assets, NASA’s Near Space and Deep Space Networks support science, technology demonstrations, and human spaceflight missions across the solar system.
“This mission is more than a technological milestone,” said Joel Parker, policy lead for positioning, navigation, and timing at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “We want to enable more and better missions to the Moon for the benefit of everyone, and we want to do it together with our international partners.”

The data-gathering LuGRE payload combines NASA-led systems engineering and mission management with receiver software and hardware developed by the Italian Space Agency and their industry partner Qascom — the first Italian-built hardware to operate on the lunar surface.
Any data LuGRE collects is intended to open the door for use of GNSS to all lunar missions, not just those by NASA or the Italian Space Agency. Approximately six months after LuGRE completes its operations, the agencies will release its mission data to broaden public and commercial access to lunar GNSS research.
Firefly Aerospace’s Blue Ghost Mission One lander is carrying 10 NASA science and technology instruments to the Moon as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative and Artemis campaign.Firefly Aerospace “A project like LuGRE isn’t about NASA alone,” said NASA Goddard navigation and mission design engineer Lauren Konitzer. “It’s something we’re doing for the benefit of humanity. We’re working to prove that lunar GNSS can work, and we’re sharing our discoveries with the world.”
The LuGRE payload is one of 10 NASA-funded science experiments launching to the lunar surface on this delivery through NASA’s CLPS initiative. Through CLPS, NASA works with American companies to provide delivery and quantity contracts for commercial deliveries to further lunar exploration and the development of a sustainable lunar economy. As of 2024, the agency has 14 private partners on contract for current and future CLPS missions.
Demonstrations like LuGRE could lay the groundwork for GNSS-based navigation systems on the lunar surface. Bridging these existing systems with emerging lunar-specific navigation solutions has the potential to define how all spacecraft navigate lunar terrain in the Artemis era.

Funding and oversight for the LuGRE payload comes from the agency’s SCaN Program office. It was chosen by NASA as one of 10 funded research and technology demonstrations for delivery to the lunar surface by Firefly Aerospace Inc, a flight under the agency’s CLPS initiative.

Modular Assembled Radiators for Nuclear Electric Propulsion Vehicles, or MARVL, aims to take a critical element of nuclear electric propulsion, its heat dissipation system, and divide it into smaller components that can be assembled robotically and autonomously in space. This is an artist’s rendering of what the fully assembled system might look like.NASA The trip to Mars and back is not one for the faint of heart. We’re not talking days, weeks, or months. But there are technologies that could help transport a crew on that round-trip journey in a relatively quick two years.
One option NASA is exploring is nuclear electric propulsion, which employs a nuclear reactor to generate electricity that ionizes, or positively charges, and electrically accelerates gaseous propellants to provide thrust to a spacecraft.
Researchers at NASA’s Langley Research Center in Hampton, Virginia, are working on a system that could help bring nuclear electric propulsion one significant, technology-defining step closer to reality.
Modular Assembled Radiators for Nuclear Electric Propulsion Vehicles, or MARVL, aims to take a critical element of nuclear electric propulsion, its heat dissipation system, and divide it into smaller components that can be assembled robotically and autonomously in space.
“By doing that, we eliminate trying to fit the whole system into one rocket fairing,” said Amanda Stark, a heat transfer engineer at NASA Langley and the principal investigator for MARVL. “In turn, that allows us to loosen up the design a little bit and really optimize it.”
Loosening up the design is key, because as Stark mentioned, previous ideas called for fitting the entire nuclear electric radiator system under a rocket fairing, or nose cone, which covers and protects a payload. Fully deployed, the heat dissipating radiator array would be roughly the size of a football field. You can imagine the challenge engineers would face in getting such a massive system folded up neatly inside the tip of a rocket.
The MARVL technology opens a world of possibilities. Rather than cram the whole system into an existing rocket, this would allow researchers the flexibility to send pieces of the system to space in whatever way would make the most sense, then have it all assembled off the planet.
Once in space, robots would connect the nuclear electric propulsion system’s radiator panels, through which a liquid metal coolant, such as a sodium-potassium alloy, would flow.
While this is still an engineering challenge, it is exactly the kind of engineering challenge in-space-assembly experts at NASA Langley have been working on for decades. The MARVL technology could mark a significant first milestone. Rather than being an add-on to an existing technology, the in-space assembly component will benefit and influence the design of the very spacecraft it would serve.
“Existing vehicles have not previously considered in-space assembly during the design process, so we have the opportunity here to say, ‘We’re going to build this vehicle in space. How do we do it? And what does the vehicle look like if we do that?’ I think it’s going to expand what we think of when it comes to nuclear propulsion,” said Julia Cline, a mentor for the project in NASA Langley’s Research Directorate, who led the center’s participation in the Nuclear Electric Propulsion tech maturation plan development as a precursor to MARVL. That tech maturation plan was run out of the agency’s Space Nuclear Propulsion project at Marshall Space Flight Center in Huntsville, Alabama.
NASA’s Space Technology Mission Directorate awarded the MARVL project through the Early Career Initiative, giving the team two years to advance the concept. Stark and her teammates are working with an external partner, Boyd Lancaster, Inc., to develop the thermal management system. The team also includes radiator design engineers from NASA’s Glenn Research Center in Cleveland and fluid engineers from NASA’s Kennedy Space Center in Florida. After two years, the team hopes to move the MARVL design to a small-scale ground demonstration.
The idea of robotically building a nuclear propulsion system in space is sparking imaginations.
“One of our mentors remarked, ‘This is why I wanted to work at NASA, for projects like this,’” said Stark, “which is awesome because I am so happy to be involved with it, and I feel the same way.”
Additional support for MARVL comes from the agency’s Space Nuclear Propulsion project. The project’s ongoing effort is maturing technologies for operations around the Moon and near-Earth exploration, deep space science missions, and human exploration using nuclear electric propulsion and nuclear thermal propulsion.
