Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA’s Lucy spacecraft has its next flyby target, the small main belt asteroid Donaldjohanson, in its sights. By blinking between images captured by Lucy on Feb. 20 and 22, this animation shows the perceived motion of Donaldjohanson relative to the background stars as the spacecraft rapidly approaches the asteroid.
NASA’s Lucy spacecraft’s first views of the asteroid Donaldjohanson. The asteroid is circled on the left to guide the eye.NASA/Goddard/SwRI/Johns Hopkins APL Lucy will pass within 596 miles (960 km) of the 2-mile-wide asteroid on April 20. This second asteroid encounter for the Lucy spacecraft will serve as a dress-rehearsal for the spacecraft’s main targets, the never-before-explored Jupiter Trojan asteroids. Lucy already successfully observed the tiny main belt asteroid Dinkinesh and its contact-binary moon, Selam, in November 2023. Lucy will continue to image Donaldjohanson over the next two months as part of its optical navigation program, which uses the asteroid’s apparent position against the star background to ensure an accurate flyby.
Donaldjohanson will remain an unresolved point of light during the spacecraft’s long approach and won’t start to show surface detail until the day of the encounter.
From a distance of 45 million miles (70 million km), Donaldjohanson is still dim, though it stands out clearly in this field of relatively faint stars in the constellation of Sextans. Celestial north is to the right of the frame, and the 0.11-degree field of view would correspond to 85,500 miles (140,000 km) at the distance of the asteroid. In the first of the two images, another dim asteroid can be seen photobombing in the lower right quadrant of the image. However, just as the headlights of an approaching car often appear relatively stationary, Donaldjohanson’s apparent motion between these two images is much smaller than that of this interloper, which has moved out of the field of view in the second image.
These observations were made by Lucy’s high-resolution camera, the L’LORRI instrument — short for Lucy LOng Range Reconnaissance Imager — provided by the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.
Asteroid Donaldjohanson is named for anthropologist Donald Johanson, who discovered the fossilized skeleton — called “Lucy” — of a human ancestor. NASA’s Lucy mission is named for the fossil.
Lucy’s principal investigator, Hal Levison, is based out of the Boulder, Colorado, branch of Southwest Research Institute, headquartered in San Antonio. NASA’s Goddard Space Flight Center in Greenbelt, Maryland, provides overall mission management, systems engineering, and safety and mission assurance. Lockheed Martin Space in Littleton, Colorado, built the spacecraft. Lucy is the 13th mission in NASA’s Discovery Program. NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Discovery Program for the Science Mission Directorate at NASA Headquarters in Washington.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
The Project F.I.R.E. team, part of Falcon Research Labs and current students at Cerritos Community College in California, is researching the use of drones to extinguish fires as part of a NASA research award called the University Student Research Challenge. From left, Logan Stahl, Juan Villa, Angel Ortega, Larisa Mayoral, Jenny Escobar, and Paola Mayoral-Jimenez.Falcon Research Labs Great ideas, and the talent and passion that bring them to life, can be found anywhere.
In that spirit, NASA’s University Student Research Challenge (USRC) in 2024 selected its first group of community college students to contribute original research to the agency’s transformative vision for 21st century aviation.
The student-led group, from Cerritos Community College in California, is researching a new method of safely extinguishing wildfires using eco-friendly pellets dropped from uncrewed drones they call Project F.I.R.E. (Fire Intervention Retardant Expeller).
“Wildfires are a major problem we’re facing today,” said Angel Ortega, project technical director and lead research engineer for Project F.I.R.E. at Cerritos Community College. “The goal of our research is to demonstrate that our prototype drone with biodegradable fire retardant can successfully put out a controlled fire.”
A Community College First
Until now, USRC has only selected participants from traditional four-year institutions, compared to a two-year community college. This award exemplifies the activity’s goal of giving all of tomorrow’s aeronautical innovators a shot at NASA support for their research ideas.
“The University Innovation (UI) project provides a number of different avenues for students to contribute to aeronautics,” said Steven Holz, who manages the USRC award process. “All of the opportunities are different and help build knowledge and skills that would be advantageous to those wanting to continue working on UI opportunities or within NASA.”
This award is one of two from NASA’s USRC selected in 2024. The team received the USRC award prior to the devastating Los Angeles fires of January 2025.
“Our thoughts are with everyone affected by this tragedy,” members of the team said in a statement. “As a team, we are deeply committed to advancing innovative solutions to enhance safety and resilience, working toward a future where communities are better protected against such disasters.”
Innovating a Solution
The six team members of Project F.I.R.E. are driven by an ethic of public service. As fires continue to affect communities in their native southern California, they are applying their skills to finding a way to help.
“We want to get the public inspired that there are possible solutions at hand,” Ortega said. “And the work we’re doing now can hopefully build towards that bigger goal of a widespread solution.”
The research they are pursuing involves dropping biodegradable pellets into fires from uncrewed, autonomous drones. The pellets, upon reaching the ground, combine chemical ingredients which create a foamlike solution of fire retardant that will not contaminate the environment after the fire is extinguished.
Project F.I.R.E.’s innovative idea for fire suppression involves releasing eco-friendly foam pellets from uncrewed drones.Falcon Research Labs The team is keen to support firefighters and wildland fire managers and keep them safe while managing these natural disasters. The group has met with firefighters, discussed the idea with them, and received useful feedback on how to make the technology work best in the field.
Though the group is only at the outset of the research, their idea has existed for longer.
Blue Skies Forever
Prior to applying for a USRC, Project F.I.R.E. also presented at NASA’s 2024 Gateway to Blue Skies competition, in which they won the “Future Game-Changer” award.
Through Gateway to Blue Skies, NASA challenges college students to research climate-friendly technologies and applications related to the future of aviation and present them at an annual forum.
Following Project F.I.R.E.’s participation in the forum, they applied for a USRC grant to begin turning their vision into reality.
“Our experience with NASA has been incredibly supportive and inspiring,” said Logan Stahl, the project’s operations director. “We thought competing against some of the other schools would be intimidating, but the experience we’ve had is the complete opposite. Everyone was very welcoming, and the NASA representatives communicated with us and asked questions.”
The USRC support will allow the team to build on their earlier foundations, they said.
“Because Gateway to Blue Skies is more conceptual, it let us bring our idea to the table. Now through USRC, we can start building hands-on and make our idea come to life,” said Larisa Mayoral, chemical engineer and laboratory operations manager.

“We’re very appreciative of our college and NASA providing us this opportunity,” said Paola Mayoral Jimenez, laboratory coordinator and safety manager. “By doing this project, we hope to shine a light on community colleges, their students, and what they have to offer.”
Complete details on USRC awardees and solicitations, such as what to include in a proposal and how to submit it, are available on the NASA Aeronautics Research Mission Directorate solicitation page.

6 Min Read NASA’s PUNCH Mission to Revolutionize Our View of Solar Wind
Earth is immersed in material streaming from the Sun. This stream, called the solar wind, is washing over our planet, causing breathtaking auroras, impacting satellites and astronauts in space, and even affecting ground-based infrastructure.
NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) mission will be the first to image the Sun’s corona, or outer atmosphere, and solar wind together to better understand the Sun, solar wind, and Earth as a single connected system.
Launching no earlier than Feb. 28, 2025, aboard a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California, PUNCH will provide scientists with new information about how potentially disruptive solar events form and evolve. This could lead to more accurate predictions about the arrival of space weather events at Earth and impact on humanity’s robotic explorers in space.
“What we hope PUNCH will bring to humanity is the ability to really see, for the first time, where we live inside the solar wind itself,” said Craig DeForest, principal investigator for PUNCH at Southwest Research Institute’s Solar System Science and Exploration Division in Boulder, Colorado.

The PUNCH mission’s four suitcase-sized satellites have overlapping fields of view that combine to cover a larger swath of sky than any previous mission focused on the corona and solar wind. The satellites will spread out in low Earth orbit to construct a global view of the solar corona and its transition to the solar wind. They will also track solar storms like coronal mass ejections (CMEs). Their Sun-synchronous orbit will enable them to see the Sun 24/7, with their view only occasionally blocked by Earth.
Typical camera images are two dimensional, compressing the 3D subject into a flat plane and losing information. But PUNCH takes advantage of a property of light called polarization to reconstruct its images in 3D. As the Sun’s light bounces off material in the corona and solar wind, it becomes polarized — meaning the light waves oscillate in a particular way that can be filtered, much like how polarized sunglasses filter out glare off of water or metal. Each PUNCH spacecraft is equipped with a polarimeter that uses three distinct polarizing filters to capture information about the direction that material is moving that would be lost in typical images.
“This new perspective will allow scientists to discern the exact trajectory and speed of coronal mass ejections as they move through the inner solar system,” said DeForest. “This improves on current instruments in two ways: with three-dimensional imaging that lets us locate and track CMEs which are coming directly toward us; and with a broad field of view, which lets us track those CMEs all the way from the Sun to Earth.”
All four spacecraft are synchronized to serve as a single “virtual instrument” that spans the whole PUNCH constellation.
Crews conduct additional solar array deployment testing for NASA’s PUNCH (Polarimeter to Unify the Corona and Heliosphere) satellites at Astrotech Space Operations located on Vandenberg Space Force Base in California on Wednesday, Jan. 22, 2025. USSF 30th Space Wing/Alex Valdez The PUNCH satellites include one Narrow Field Imager and three Wide Field Imagers. The Narrow Field Imager (NFI) is a coronagraph, which blocks out the bright light from the Sun to better see details in the Sun’s corona, recreating what viewers on Earth see during a total solar eclipse when the Moon blocks the face of the Sun — a narrower view that sees the solar wind closer to the Sun. The Wide Field Imagers (WFI) are heliospheric imagers that view the very faint, outermost portion of the solar corona and the solar wind itself — giving a wide view of the solar wind as it spreads out into the solar system.
“I’m most excited to see the ‘inbetweeny’ activity in the solar wind,” said Nicholeen Viall, PUNCH mission scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “This means not just the biggest structures, like CMEs, or the smallest interactions, but all the different types of solar wind structures that fill that in between area.”
When these solar wind structures from the Sun reach Earth’s magnetic field, they can drive dynamics that affect Earth’s radiation belts. To launch spacecraft through these belts, including ones that will carry astronauts to the Moon and beyond, scientists need to understand the solar wind structure and changes in this region.
Building Off Other Missions
“The PUNCH mission is built on the shoulders of giants,” said Madhulika Guhathakurta, PUNCH program scientist at NASA Headquarters in Washington. “For decades, heliophysics missions have provided us with glimpses of the Sun’s corona and the solar wind, each offering critical yet partial views of our dynamic star’s influence on the solar system.”
When scientists combine data from PUNCH and NASA’s Parker Solar Probe, which flies through the Sun’s corona, they will see both the big picture and the up-close details. Working together, Parker Solar Probe and PUNCH span a field of view from a little more than half a mile (1 kilometer) to over 160 million miles (about 260 million kilometers).
Additionally, the PUNCH team will combine their data with diverse observations from other missions, like NASA’s CODEX (Coronal Diagnostic Experiment) technology demonstration, which views the corona even closer to the surface of the Sun from its vantage point on the International Space Station. PUNCH’s data also complements observations from NASA’s EZIE (Electrojet Zeeman Imaging Explorer) — targeted for launch in March 2025 — which investigates the magnetic field perturbations associated with Earth’s high-altitude auroras that PUNCH will also spot in its wide-field view.

NASA’s Goddard Space Flight Center Conceptual Image Lab As the solar wind that PUNCH will observe travels away from the Sun and Earth, it will then be studied by the IMAP (Interstellar Mapping and Acceleration Probe) mission, which is targeting a launch in 2025.
“The PUNCH mission will bridge these perspectives, providing an unprecedented continuous view that connects the birthplace of the solar wind in the corona to its evolution across interplanetary space,” said Guhathakurta.
The PUNCH mission is scheduled to conduct science for at least two years, following a 90-day commissioning period after launch. The mission is launching as a rideshare with the agency’s next astrophysics observatory, SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization and Ices Explorer).
“PUNCH is the latest heliophysics addition to the NASA fleet that delivers groundbreaking science every second of every day,” said Joe Westlake, heliophysics division director at NASA Headquarters in Washington. “Launching this mission as a rideshare bolsters its value to the nation by optimizing every pound of launch capacity to maximize the scientific return for the cost of a single launch.”
The PUNCH mission is led by Southwest Research Institute’s offices in San Antonio, Texas, and Boulder, Colorado. The mission is managed by the Explorers Program Office at NASA Goddard for NASA’s Science Mission Directorate in Washington.
