“Houston, Tranquility Base here, the Eagle has landed.” “That’s one small step for [a] man, one giant leap for mankind.” “Magnificent desolation.” Three phrases that recall humanity’s first landing on and exploration of the lunar surface. In July 1969, Apollo 11 astronauts Neil A. Armstrong, Michael Collins, and Edwin E. “Buzz” Aldrin completed humanity’s first landing on the Moon. They fulfilled President John F. Kennedy’s national goal, set in May 1961, to land a man on the Moon and return him safely to the Earth before the end of the decade. Scientists began examining the first Moon rocks two days after the Apollo 11 splashdown while the astronauts began a three-week postflight quarantine.

      Steve Platnick Steps Down from NASA After 34 Years of Service
      By NASA
      Dr. Steven “Steve” Platnick took the NASA agency Deferred Resignation Program (DRP). His last work day was August 8, 2025. Steve spent more than three decades at, or associated with, NASA. While he began his civil servant career at the NASA’s Goddard Space Flight Center (GSFC) in 2002, his Goddard association went back to 1993, first as a contractor and then as one of the earliest employees of the Joint Center for Earth Systems Technology (JCET), a cooperative agreement between the University of Maryland, Baltimore County (UMBC) and GSFC’s Earth Science Division. At JCET Steve helped lead the development of the Atmosphere Physics Track curricula. Previously, he had held an NRC post-doctoral fellow at the NASA’s Ames Research Center. Along with his research work on cloud remote sensing from satellite and airborne sensors, Steve served as the Deputy Director for Atmospheres in GSFC’s Earth Sciences Division from January 2015–July 2024.
      Dr. Steve Platnick Image credit: NASA During his time at NASA, Steve played an integral role in the sustainability and advancement of NASA’s Earth Observing System platforms and data. In 2008, he took over as the Earth Observing System (EOS) Senior Project Scientist from Michael King. In this role, he led the EOS Project Science Office, which included support for related EOS facility airborne sensors, ground networks, and calibration labs. The office also supported The Earth Observer newsletter, the NASA Earth Observatory, and other outreach and exhibit activities on behalf of NASA Headquarter’s Earth Science Division and Science Mission Directorate (further details below). From January 2003 – February 2010, Steve served as the Aqua Deputy Project Scientist.
      Improving Imager Cloud Algorithms
      Steve was actively involved in the Moderate Resolution Imaging Spectroradiometer (MODIS) Science Team serving as the Lead for the MODIS Atmosphere Discipline Team (cloud, aerosol and clear sky products) since 2008 and as the NASA Suomi National Polar-orbiting Partnership (Suomi NPP)/JPSS Atmosphere Discipline Lead/co-Lead from 2012–2020. His research team enhanced, maintained, and evaluated MODIS and Visible Infrared Imaging Radiometer Suite (VIIRS) cloud algorithms that included Level-2 (L2) Cloud Optical/Microphysical Properties components (MOD06 and MYD06 for MODIS on Terra and Aqua, respectively) and the Atmosphere Discipline Team Level-3 (L3) spatial/temporal products (MOD08, MYD08). The L2 cloud algorithms were developed to retrieve thermodynamic phase, optical thickness, effective particle radius, and derived water path for liquid and ice clouds, among other associated datasets. Working closely with longtime University of Wisconsin-Madison colleagues, the team also developed the CLDPROP continuity products designed to bridge the MODIS and VIIRS cloud data records by addressing differences in the spectral coverage between the two sensors; this product is currently in production for VIIRS on Suomi NPP and NOAA-20, as well as MODIS Aqua. The team also ported their CLDPROP code to Geostationary Operational Environmental Satellites (GOES) R-series Advanced Baseline Imager (ABI) and sister sensors as a research demonstration effort.
      Steve’s working group participation included the Global Energy and Water Exchanges (GEWEX) Cloud Assessment Working Group (2008–present); the International Cloud Working Group (ICWG), which is part of the Coordination Group for Meteorological Satellites (CGMS), and its original incarnation, the Cloud Retrieval Evaluation Working (CREW) since 2009; and the NASA Observations for Modeling Intercomparison Studies (obs4MIPs) Working Group (2011–2013). Other notable roles included Deputy Chair of the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Science Definition Team (2011–2012) and membership in the Advanced Composition Explorer (ACE) Science Definition Team (2009–2011), the ABI Cloud Team (2005–2009), and the Climate Absolute Radiance and Refractivity Observatory (CLARREO) Mission Concept Team (2010-2011).
      Steve has participated in numerous major airborne field campaigns over his career. His key ER-2 flight scientist and/or science team management roles included the Monterey Area Ship Track experiment (MAST,1994), First (International Satellite Cloud Climatology Project (ISCCP) Regional Experiment – Arctic Cloud Experiment [FIRE-ACE, 1998], Southern Africa Fire-Atmosphere Research Initiative (SAFARI-2000), Cirrus Regional Study of Tropical Anvils and Cirrus Layers – Florida Area Cirrus Experiment (CRYSTAL-FACE, 2002), and Tropical Composition, Cloud and Climate Coupling (TC4, 2007).
      Supporting Earth Science Communications
      Through his EOS Project Science Office role, Steve has been supportive of the activities of NASA’s Science Support Office (SSO) and personally participated in many NASA Science exhibits at both national and international scientific conferences, including serving as a Hyperwall presenter numerous times.
      For The Earth Observer newsletter publication team in particular, Steve replaced Michael King as Acting EOS Senior Project Scientist in June 2008, taking over the authorship of “The Editor’s Corner” beginning with the May–June 2008 issue [Volume 20, Issue 3]. The Acting label was removed beginning with the January–February 2010 issue [Volume 22, Issue 1]. Steve has been a champion of continuing to retain a historical record of NASA science team meetings to maintain a chronology of advances made by different groups within the NASA Earth Science community. He was supportive of the Executive Editor’s efforts to create a series called “Perspectives on EOS,” which ran from 2008–2011 and told the stories of the early years of the EOS Program from the point of view of those who lived them. He also supported the development of articles to commemorate the 25th and 30th anniversary of The Earth Observer. Later, Steve helped guide the transition of the newsletter from a print publication – the November–December 2022 issue was the last printed issue – to fully online by July 2024, a few months after the publication’s 35th anniversary. The Earth Observer team will miss Steve’s keen insight, historical perspective, and encouragement that he has shown through his leadership for the past 85 issues of print and online publications.
      A Career Recognized through Awards and Honors
      Throughout his career, Steve has amassed numerous honors, including the Goddard William Nordberg Memorial Award for Earth Science in 2023 and the Verner E. Suomi Award from the American Meteorological Society (AMS) in 2016. He was named an AMS Fellow that same year. He received two NASA Agency Honor Awards – the Exceptional Achievement Medal in 2008 and the Exceptional Service Medal in 2015.
      Steve received his bachelor’s degree and master’s degree in electrical engineering from Duke University and the University of California, Berkeley, respectively. He earned a Ph.D. in atmospheric sciences from the University of Arizona.

      Small Companies Win Big in NASA’s TechLeap Challenge
      By NASA
      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.

      NASA’s Apollo Samples, LRO Help Scientists Predict Moonquakes

      NASA’s Apollo Samples, LRO Help Scientists Predict Moonquakes
      This mosaic of the Taurus-Littrow valley was made using images from the Narrow Angle Cameras onboard NASA’s Lunar Reconnaissance Orbiter. The orbiter has been circling and studying the Moon since 2009. The ancient-lava-filled valley is cut by the Lee-Lincoln thrust fault, visible as a sinuous, white line extending from South Massif (mountain in the bottom left corner) to North Massif (mountain in the top center) where the fault abruptly changes direction and cuts along the slope of North Massif. The Lee-Lincoln fault has been the source of multiple strong moonquakes causing landslides and boulder falls on both North and South massifs. The approximate location of the Apollo 17 landing site is indicated to the right of the fault with a white “x”. NASA/ASU/Smithsonian As NASA prepares to send astronauts to the surface of the Moon’s south polar region for the first time ever during the Artemis III mission, scientists are working on methods to determine the frequency of moonquakes along active faults there.
      Faults are cracks in the Moon’s crust that indicate that the Moon is slowly shrinking as its interior cools over time. The contraction from shrinking causes the faults to move suddenly, which generates quakes. Between 1969 and 1977, a network of seismometers deployed by Apollo astronauts on the Moon’s surface recorded thousands of vibrations from moonquakes.
      Moonquakes are rare, with the most powerful ones, about magnitude 5.0, occurring near the surface. These types of quakes are much weaker than powerful quakes on Earth (magnitude 7.0 or higher), posing little risk to astronauts during a mission lasting just a few days. But their effects on longer-term lunar surface assets could be significant. Unlike an earthquake that lasts for tens of seconds to minutes, a moonquake can last for hours, enough time to damage or tip over structures, destabilize launch vehicles on the surface, or interrupt surface operations.
      “The hazard probability goes way up depending on how close your infrastructure is to an active fault,” said Thomas Watters, senior scientist emeritus at the Smithsonian’s National Air & Space Museum in Washington.
      Watters is a long-time researcher of lunar geology and a co-investigator on NASA’s LRO (Lunar Reconnaissance Orbiter) camera. Recently, he and Nicholas Schmerr, a planetary seismologist at the University of Maryland in College Park, developed a new method for estimating the magnitude of seismic shaking by analyzing evidence of dislodged boulders and landslides in an area, as the scientists reported on July 30 in the journal Science Advances. Studies like these can help NASA plan lunar surface assets in safer locations.
      Unlike an earthquake that lasts for tens of seconds to minutes, a moonquake can last for hours, enough time to damage or tip over structures, destabilize launch vehicles on the surface, or interrupt surface operations.


      There are thousands of faults across the Moon that may still be active and producing quakes. Watters and his team have identified these faults by analyzing data from LRO, which has been circling the Moon since 2009, mapping the surface and taking pictures, providing unprecedented detail of features like faults, boulders, and landslides.
      For this study, Watters and Schmerr chose to analyze surface changes from quakes generated by the Lee-Lincoln fault in the Taurus-Littrow valley. NASA’s Apollo 17 astronauts, who landed about 4 miles west of the fault on Dec. 11, 1972, explored the area around the fault during their mission.
      By studying boulder falls and a landslide likely dislodged by ground shaking near Lee Lincoln, Watters and Schmerr estimated that a magnitude 3.0 moonquake — similar to a relatively minor earthquake — occurs along the Lee Lincoln fault about every 5.6 million years.
      “One of the things we’re learning from the Lee-Lincoln fault is that many similar faults have likely had multiple quakes spread out over millions of years,” Schmerr said. “This means that they are potentially still active today and may keep generating more moonquakes in the future.”
      The authors chose to study the Lee-Lincoln fault because it offered a unique advantage: Apollo 17 astronauts brought back samples of boulders from the area. By studying these samples in labs, scientists were able to measure changes in the boulders’ chemistry caused by exposure to cosmic radiation over time (the boulder surface is freshly exposed after breaking off a larger rock that would have otherwise shielded it).
      This cosmic radiation exposure information helped the researchers determine how long the boulders had been sitting in their current locations, which in turn helped inform the estimate of possible timing and frequency of quakes along the Lee-Lincoln fault.
      This 1972 image shows Apollo 17 astronaut Harrison H. Schmitt sampling a boulder at the base of North Massif in the Taurus-Littrow valley on the Moon. This large boulder is believed to have been dislodged by a strong moonquake that occurred about 28.5 million years ago. The source of the quake was likely a seismic event along the Lee-Lincoln fault. The picture was taken by astronaut Eugene A. Cernan, Apollo 17 commander. NASA/JSC/ASU Apollo 17 astronauts investigated the boulders at the bases of two mountains in the valley. The tracks left behind indicated that the boulders may have rolled downhill after being shaken loose during a moonquake on the fault. Using the size of each boulder, Watters and Schmerr estimated how hard the ground shaking would have been and the magnitude of the quake that would have caused the boulders to break free.
      The team also estimated the seismic shaking and quake magnitude that would be needed to trigger the large landslide that sent material rushing across the valley floor, suggesting that this incident caused the rupture event that formed the Lee-Lincoln fault.
      A computer simulation depicting the seismic waves emanating from a shallow moonquake on the Lee-Lincoln fault in the Taurus-Littrow valley on the Moon. The label “A17” marks the Apollo 17 landing site. The audio represents a moonquake that was recorded by a seismometer placed on the surface by astronauts. The seismic signal is converted into sound. Both audio and video are sped up to play 10 times faster than normal. The background image is a globe mosaic image from NASA’s Lunar Reconnaissance Orbiter’s Wide-Angle Camera. Red and blue are positive (upward ground motion) and negative (downward ground motion) polarities of the wave. Nicholas Schmerr Taking all these factors into account, Watters and Schmerr estimated that the chances that a quake would have shaken the Taurus-Littrow valley on any given day while the Apollo 17 astronauts were there are 1 in 20 million, the authors noted.
      Their findings from the Lee-Lincoln fault are just the beginning. Watters and Schmerr now plan to use their new technique to analyze quake frequency at faults in the Moon’s south polar region, where NASA plans to explore.
      NASA also is planning to send more seismometers to the Moon. First, the Farside Seismic Suite will deliver two sensitive seismometers to Schrödinger basin on the far side of the Moon onboard a lunar lander as part of NASA’s CLPS (Commercial Lunar Payload Services) initiative. Additionally, NASA is developing a payload, called the Lunar Environment Monitoring Station, for potential flight on NASA’s Artemis III mission to the South Pole region. Co-led by Schmerr, the payload will assess seismic risks for future human and robotic missions to the region.
