NASA Names Scientists to Support Lunar South Pole Science

NASA Names Scientists to Support Lunar South Pole Science

NASA has selected 10 participating scientists to help shape a science plan for astronauts to complete on the lunar surface under the Artemis program – including deploying scientific instruments, making critical observations of the landing site, and collecting Moon rocks.

“Congratulations to the scientists selected to participate in this important Artemis lunar surface science team,” said Joel Kearns, deputy associate administrator for exploration, Science Mission Directorate, NASA Headquarters in Washington. “The selected scientists will bring a wealth of expertise to this team to ensure we are supporting crews on the Moon to achieve the missions’ science objectives. Exploring the lunar surface and executing the U.S.’s science objectives is a major step toward sustained operations at the Moon and preparation for human exploration of Mars.”

The selected scientists are:

  • Kristen Bennett, Northern Arizona University in Flagstaff
  • Aleksandra Gawronska, The Catholic University of America in Washington
  • Timothy Glotch, State University of New York, Stony Brook
  • Paul Hayne, University of Colorado, Boulder
  • Erica Jawin, Smithsonian Institution in Washington
  • Jeannette Luna, Tennessee Technological University in Cookeville
  • Sabrina Martinez, NASA’s Johnson Space Center in Houston
  • Jamie Molaro, Planetary Science Institute in Tucson, Arizona
  • Hanna Sizemore, Planetary Science Institute
  • Catherine Weitz, Planetary Science Institute

The participating scientists will join the first Artemis lunar surface science team, led by Noah Petro, project scientist, at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and Padi Boyd, deputy project scientist, at NASA Headquarters. In this role, they will support the inaugural Artemis geology team, led by Brett Denevi of the Johns Hopkins University Applied Physics Laboratory in Laurel, Maryland. The larger team also includes deployed instrument teams and the Artemis internal science team.

“Artemis is enabling the kind of scientific work that will reshape our understanding of the Moon and open the door to discoveries we’ve only imagined,” said Lakiesha Hawkins, acting deputy associate administrator, Exploration Systems Development Mission Directorate at NASA Headquarters. “The work these scientists will contribute before, during, and after the mission will help us make the most of every step astronauts take on the lunar surface and ensure we’re learning as much as possible from this new era of human exploration.”

During the mission, astronauts will land near the Moon’s South Pole, a landscape of extremes with dark craters that contain may contain ice and mountain peaks in near-constant illumination. The scientific research during the first crewed Artemis lunar landing mission will provide critical data to support further exploration while digging deeper into questions that have intrigued scientists since the Apollo era – such as the impact history of the Moon or the locations of shallow ice deposits. In addition, the processes that the science team develops and tests during the first Artemis landed lunar mission will provide the framework for science operations during increasingly difficult missions to explore more of the Moon’s surface and subsurface.

The selected participants will engage in pre-mission planning, science mission operations, and work preparing the post-mission reports to address these questions.  

Through Artemis, NASA will address high priority science questions in a Golden Age of exploration and discovery, focusing on those best accomplished by human explorers on and around the Moon and by using the unique attributes of the lunar environment. The Artemis missions will send astronauts to explore the Moon for scientific discovery, economic benefits, and build the foundation for the first crewed missions to Mars.

I Am Artemis: Michael Guzman

Portrait of Mike Guzman in front of the Launch Control Center at Kennedy Space Center.

Listen to this audio excerpt from Michael Guzman, Artemis II main propulsion systems engineer:

0:00 / 0:00

A clue to what Mike Guzman, main propulsion systems engineer at NASA’s Kennedy Space Center in Florida, loves most can be found in the signature of his work email: a complex string of equations for rocket thrust, specific impulse, and the physics behind cooling liquid oxygen with helium bubbles.

I’m a huge nerd. I love math, science, and physics. Even in my free time, I’ll find myself watching physics lectures.

Artemis II main propulsion systems engineer

Born in New York to a family from the Dominican Republic, Guzman moved to Florida where he earned a bachelor’s degree in mechanical engineering at Florida International University and a master’s degree in space systems from the Florida Institute of Technology. His path to NASA Kennedy began after being handpicked for a summer internship in 2013, an opportunity that would ultimately change the course of his career.

During his internship, Guzman was inspired to build his own rocket. He purchased a textbook and began building a model rocket in his free time. The drive and passion he put into the project did not go unnoticed. Just three days after the model rocket launched, he was offered a job and has worked for America’s space agency ever since.

Mike Guzman, main propulsion systems engineer, participates in a wet dress rehearsal for the Artemis II mission on Monday, Feb. 2, 2026, inside Firing Room 1 at the Rocco A. Petrone Launch Control Center at NASA’s Kennedy Space Center in Florida. The wet dress rehearsal allows the Artemis II launch team to run through operations to load propellant, conduct a full launch countdown, demonstrate the ability to recycle the countdown clock, and drain the tanks to practice timelines and procedures for launch.

Guzman began his work with a model rocket, and now, as part of Exploration Ground Systems, is part of the team launching the rocket that will carry astronauts around the Moon for the first time in more than 50 years: the SLS (Space Launch System) rocket for Artemis II.

Guzman joined the propulsion team in 2019. Early in his role, he focused on hydrogen systems at Launch Pad 39B, including the large liquid hydrogen sphere at the pad and the piping that delivers propellant to the rocket. Today, he works on the main propulsion system inside the rocket itself, a role that will put him in the firing room for the Artemis II test flight, at the center of launch operations.

At the heart of Guzman’s work is the “brain book,” a comprehensive binder that contains every drawing, requirement, procedure, and launch commit criteria an engineer might need. It’s a roadmap for efficiency. By studying it in advance, Guzman and his colleagues know exactly where to find what they need and how to respond to unexpected issues.

The key to a successful launch relies on teamwork. On launch day, hundreds of engineers come together in the firing room to monitor every system on the spacecraft. Each console operator’s actions influence the others’, creating a constant interplay where observation, communication, and anticipation are key to mission success.

It has to be a team sport. We’re all sitting in different parts of a whole, that ‘one whole’ being the spacecraft. We all have to work together. We all must have a sense of what the other individuals are doing and what their roles are, because at the end of the day, it’s all interconnected.

For Guzman, Artemis II represents the culmination of years of preparation, study, and collaboration.

“It’s not something that happens every day, and it’s not something that you get to be a part of every day,” Guzman said. “To see it finally happen, it’s going to be incredible.”

NextSTEP-3 E: Network Extension for User Continuity and Sustainability (NEXUS) Ka-Band Backward-Compatible Relay Broad

NextSTEP-3 E: Network Extension for User Continuity and Sustainability (NEXUS) Ka-Band Backward-Compatible Relay Broad

Synopsis | 03/23/26

https://sam.gov/workspace/contract/opp/e33cd0cc61064a6497a55fca8e9b30c6/view

NASA intends to release a BAA under Next Space Technologies for Exploration Partnerships (NextSTEP-3), Appendix E, for Project NEXUS, Ka-band Backward- Compatible Relay. As the aging Tracking and Data Relay Satellite System (TDRS) declines, NASA’s objective is to acquire an end-to-end Ka-band relay service, including space, ground, launch, integration, and operations elements, that is backward compatible with legacy TDRS users for a minimum of fifteen years. This capability is needed to support select on-orbit missions that cannot feasibly modify flight hardware or transition to non-compatible commercial services. To reduce growing continuity risk in the 2029- 2031 timeframe, industry is asked to develop and demonstrate this end-to-end capability. The BAA will be a phased competitive Research and Development (R&D) acquisition. NASA anticipates multiple initial Firm-Fixed-Price (FFP) awards with progressive downselects based on demonstrated performance, technical credibility, and commercial viability. NASA does not anticipate being the sole commercial customer and anticipates proposed solutions to be supported by a broader commercial business case beyond NASA. 

NASA seeks to accelerate maturation of commercially viable capabilities through competitive research demonstrations to support transition to future operational services, while preserving full and open competition for those services. All proposed satellite orbit solutions are acceptable notwithstanding that the proposed solutions will be expected to include all elements necessary for industry to develop, deliver and sustain the end-to-end relay service capability, including, but not limited to: Space segment, associated launch services, as applicable, ground and network infrastructure, and service operations and maintenance. Accordingly, NASA may use knowledge gained through this BAA, including demonstration results, technical data, and operational insight, to inform future acquisition strategies for operational services.

Satellite Spots a Spawn

Satellite Spots a Spawn

Spawning season has sprung for Pacific herring (Clupea pallasii) in the waters off British Columbia, Canada. From mid-February through early May each year, thousands of the small, silvery fish congregate in shallow coastal areas around Vancouver Island and create a spectacle sometimes visible to satellites.

Sheltered waters in Barkley Sound, on the southwestern side of Vancouver Island, are regular sites for spawn events. On February 19, 2026, the Landsat 9 satellite caught a glimpse of early-season activity underway along the shore near Forbes Island. In these events, female herring produce eggs that stick to a variety of materials, from kelp and seagrass to rock surfaces. Males release a sperm-containing fluid called milt into the water, giving it a cloudy green or turquoise look.

Spawns near Forbes Island have been observed most years since the 1970s, according to Fisheries and Oceans Canada (DFO) records. “Herrings prefer spawning locations that are more protected, have rocky substrate, and allow them to select areas with reduced salinity,” said Jessica Moffatt, biologist with the Island Marine Aquatic Working Group (IMAWG), which works to strengthen First Nations fisheries through traditional knowledge, modern science, and management guidance. “Barkley Sound hits the sweet spot” in many of these regards, she said, adding that collective memory, predation pressure, and other factors also play a role in spawn size and location.

Spawning events last from several hours to several days. At Forbes Island in 2026, local observers saw that fish were staging in the area by February 13 (schools can arrive up to two weeks before spawning, Moffatt noted), and activity was reported to IMAWG from February 19 to February 21.

Along with changes in water color, spawns often come with increased wildlife presence, which can include whales and sea lions swimming nearby and eagles, wolves, and bears lurking on shore. After spawning, the fish will migrate back to summer feeding areas in deeper, more nutrient-rich waters, sometimes sticking with their same large school for several years.

Records of spawn activity have historically been constrained by the timing of aerial and dive surveys, the availability of reports from remote locations, and fisheries priorities. But observations by satellites, including Landsat, can help monitor herring activity over larger areas and longer periods of time. Researchers at the University of Victoria in Canada have used decades of satellite observations to augment historical spawn records and develop methods to streamline future detections.

Herring and their roe are valuable both as a cultural food source and harvest practice by First Nations and for British Columbia’s commercial fisheries. As a forage fish species, Pacific herring are vital to salmon and other marine life, and a fuller picture of the locations of spawning areas could provide clues about changes in the marine ecosystem.
