Preparations for Next Moonwalk Simulations Underway (and Underwater)
Earth scientist Compton J. Tucker has been elected to the National Academy of Sciences for his work creating innovative tools to track the planet’s changing vegetation from space. It’s research that has spanned nearly 50 years at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, where he is a visiting scientist after retiring in March.
Tucker’s research began with identifying wavelengths of light that are absorbed or reflected as plants undergo photosynthesis, and has evolved into calculating the health and productivity of vegetation over time with satellites.
“I’m honored and surprised,” Tucker said of his election. “There were opportunities at the Goddard Space Flight Center that have enabled this work that couldn’t be found elsewhere. There were people who built satellites, who understood satellite data, and had the computer code to process it. All the work I’ve done has been part of a team, with other people contributing in different ways. Working at NASA is a team effort of science and discovery that’s fun and intellectually rewarding.”
Earth scientist Compton Tucker, who has studied remote sensing of vegetation at NASA Goddard for 50 years, has been elected to the National Academy of Sciences.Courtesy Compton Tucker Tucker earned his master’s and doctoral degrees from Colorado State University, where he worked on a National Science Foundation-funded project analyzing spectrometer data of grassland ecosystems. In 1975, he came to NASA Goddard as a postdoctoral fellow and used what he learned in his graduate work to modify the imager on National Oceanic and Atmospheric Administration (NOAA) meteorological satellites and modify Landsat’s thematic mapper instrument.
He became a civil servant at the agency in 1977, and continued work with radiometers to study vegetation – first with handheld devices, then with NOAA’s Advanced Very High Resolution Radiometer satellite instruments. He has also used data from Landsat satellites, Moderate Resolution Imaging Spectroradiometer instruments, and commercial satellites. His scientific papers have been cited 100,000 times, and one of his recent studies mapped 10 billion individual trees across Africa’s drylands to inventory carbon storage at the tree level.
“The impact of Compton Tucker’s work over the last half-century at Goddard is incredible,” said Dalia Kirschbaum, director of the Earth Sciences Division at NASA Goddard. “Among his many achievements, he essentially developed the technique of using satellites to study photosynthesis from plants, which people have used to monitor droughts, forecast crop shortages, defeat the desert locust, and even predict disease outbreaks. This is a well-deserved honor.”

Each year, up to 120 new members are elected “in recognition of their distinguished and continuing achievements in original research,” according to the organization.
In addition his role as a visiting scientist at Goddard, Tucker is also an adjunct professor at the University of Maryland and a consulting scholar at the University of Pennsylvania’s University Museum. He was awarded the National Air and Space Collins Trophy for Current Achievement in 1993 and the Vega Medal by the Swedish Society of Anthropology and Geography in 2014. He is a fellow of the American Association for the Advancement of Science and the American Geophysical Union, and won the Senior Executive Service Presidential Rank Award for Meritorious Service in 2017, among other honors.

This team from University High School in Irvine, California, won the 2025 regional Oceans Science Bowl, hosted by NASA’s Jet Propulsion Laboratory. From left: Nethra Iyer, Joanne Chen, Matthew Feng, Avery Hexun, Angelina Yan, and coach David Knight.NASA/JPL-Caltech The annual regional event puts students’ knowledge of ocean-related science to the test in a fast-paced academic competition.
A team of students from University High School in Irvine earned first place at a fast-paced regional academic competition focused on ocean science disciplines and hosted by NASA’S Jet Propulsion Laboratory in Southern California.
Eight teams from Los Angeles and Orange counties competed at the March 29 event, dubbed the Los Angeles Surf Bowl. It was the last of about 20 regional competitions held across the U.S. this year in the lead-up to the virtual National Ocean Sciences Bowl finals event in mid-May.
Santa Monica High School earned second place; Francisco Bravo Medical Magnet High School in Los Angeles came in third. With its victory, University repeated its winning performance from last year. The school also won the JPL-hosted regional Science Bowl earlier this month.
Teams from all eight schools that participated in the JPL-hosted 2025 regional Ocean Sciences Bowl pose alongside volunteers and coaches.NASA/JPL-Caltech For the Ocean Sciences Bowl, teams are composed of four to five students and a coach. To prepare for the event, team members spend months answering multiple-choice questions with a “Jeopardy!”-style buzzer in just five seconds. Questions come in several categories, including biology, chemistry, geology, and physics along with related geography, technology, history, policy, and current events topics.
A question in the chemistry category might be “What chemical is the principal source of energy at many of Earth’s hydrothermal vent systems?” (It’s hydrogen sulfide.) Other questions can be considerably more challenging.
When a team member buzzes in and gives the correct answer to a multiple-choice question, the team earns a bonus question, which allows teammates to consult with one another to come up with an answer. More complicated “team challenge questions” prompt students to work together for a longer period. The theme of this year’s competition is “Sounding the Depths: Understanding Ocean Acoustics.”
University High junior Matthew Feng, a return competitor, said the team’s success felt like a payoff for hours of studying together, including on weekends. He keeps coming back to the competition partly for the sense of community and also for the personal challenge, he said. “It’s nice to compete and meet people, see people who were here last year,” Matthew added. “Pushing yourself mentally — the first year I was shaking so hard because I wasn’t used to that much adrenaline.”
Since 2000, JPL’s Public Services Office has coordinated the Los Angeles regional contest with the help of volunteers from laboratory staff and former Ocean Sciences Bowl participants in the local community. JPL is managed for NASA by Caltech.
The National Ocean Sciences Bowl is a program of the Center for Ocean Leadership at the University Corporation for Atmospheric Research, a nonprofit consortium of colleges and universities focused in part on Earth science-related education.

On Dec. 19, 2024, NASA released two amendments to the NASA Research Announcement Research Opportunities in Space and Earth Sciences (ROSES) 2024 (NNH24ZDA001N) to announce the E.9 Space Biology: Research Studies and E.12 Physical Sciences Research Studies program elements.
Space Biology Proposals
The research emphases of E.9 Space Biology: Research Studies fall under two broad categories: Precision Health and Space Crops
For Precision Health-focused studies, investigators may propose to use any non-primate animal model system and any appropriate cell/tissue culture/microphysiological system/organoid or microbial models that are supported by the chosen platform. For Space Crop-focused studies, applicants may propose to use any plant, relevant microbe, and/or plant and microbe model system(s) that is (are) supported by the chosen platform. The E.9 Space Biology: Research Studies opportunity includes five different Project Types: Research Investigations, Early Career Research Investigations, New NASA Investigators, OSDR Analytical Investigations, and Tissue Sharing Investigations. Specific requirements for each of these Project Types are described in the program element text. Questions concerning E.9 Space Biology: Research Studies may be directed to Lynn Harrison (for Precision Health) and Elison Blancaflor (for Space Crops) at nasa-spacebiology@mail.nasa.gov.
Physical Sciences Proposals
E.12 Physical Sciences: Research Studies solicits proposals to investigate physical phenomena in the absence of gravity and fundamental laws that describe the universe, and applied research that contributes to the basic understanding of processes underlying space exploration technologies.
The Physical Sciences program is divided into two key goals: Foundations and Quantum Leaps. Foundations focuses on understanding the behavior of fluids, combustion, soft matter, and materials in the spaceflight environment. Quantum Leaps aims to probe the very nature of the universe using exquisitely precise space-based quantum sensors to test the Einstein equivalence principle, dark sector physics, and the nature of fundamental physical constants.
The E.12 Physical Sciences: Research Studies opportunity will include four different Project Types: Research Investigations, New NASA Investigators, Physical Sciences Informatics, and Fundamental Physics Investigations. Specific requirements for each of these Project Types are described in detail in the program element text. Questions concerning E.12 Physical Sciences Research Studies may be directed to Brad Carpenter (regarding Foundations and PSI) or Mike Robinson (regarding Quantum Leaps) by writing to BPS-PhysicalSciences@nasaprs.com.
Town Hall
A pre-proposer’s townhall for applicants interested in submitting a proposal to these program elements will be held virtually on Jan. 22, 2025, at 3 p.m. Eastern Time. Meeting information will be posted on the NSPIRES page for each of the program elements under “Other Documents.”
Proposals to these program elements shall be submitted via a two-step process
Step-1 proposals must be submitted by Feb. 4, 2025 Step-2 proposals are due on May 6, 2025 Related Resources:
