Preparations for Next Moonwalk Simulations Underway (and Underwater)
NASA now is accepting proposals from student teams for a contest to design, build, and test rovers for Moon and Mars exploration through Sept. 15.
Known as the Human Exploration Rover Challenge, student rovers should be capable of traversing a course while completing mission tasks. The challenge handbook has guidelines for remote-controlled and human-powered divisions.
The cover of the HERC 2026 handbook, which is now available online. “Last year, we saw a lot of success with the debut of our remote-controlled division and the addition of middle school teams,” said Vemitra Alexander, the activity lead for the challenge at NASA’s Marshall Space Flight Center in Huntsville, Alabama. “We’re looking forward to building on both our remote-controlled and human-powered divisions with new challenges for the students, including rover automation.”
This year’s mission mimics future Artemis missions to the lunar surface. Teams are challenged to test samples of soil, water, and air from sites along a half-mile course that includes a simulated field of asteroid debris, boulders, erosion ruts, crevasses, and an ancient streambed. Human-powered rover teams will play the role of two astronauts in a lunar terrain vehicle and must use a custom-built task tool to manually collect samples needed for testing. Remote-controlled rover teams will act as a pressurized rover, and the rover itself will contain the tools necessary to collect and test samples onboard.
“NASA’s Human Exploration Rover Challenge creates opportunities for students to develop the skills they need to be successful STEM professionals,” said Alexander. “This challenge will help students see themselves in the mission and give them the hands-on experience needed to advance technology and become the workforce of tomorrow.”
Seventy-five teams comprised of more than 500 students participated in the agency’s 31st rover challenge in 2025. Participants represented 35 colleges and universities, 38 high schools, and two middle schools, across 20 states, Puerto Rico, and 16 nations around the world.
The 32nd annual competition will culminate with an in-person event April 9-11, 2026, at the U.S. Space & Rocket Center near NASA Marshall.
The rover challenge is one of NASA’s Artemis Student Challenges, reflecting the goals of the Artemis campaign, which seeks to explore the Moon for scientific discovery, technology advancement, and to learn how to live and work on another world as we prepare for human missions to Mars. NASA uses such challenges to encourage students to pursue degrees and careers in the fields of science, technology, engineering, and mathematics.
Since its inception in 1994, more than 15,000 students have participated in the rover challenge – with many former students now working at NASA or within the aerospace industry.

Hubble Examines Low Brightness, High Interest Galaxy
This NASA/ESA Hubble Space Telescope image features a portion of the spiral galaxy NGC 45. ESA/Hubble & NASA, D. Calzetti, R. Chandar; Acknowledgment: M. H. Özsaraç This NASA/ESA Hubble Space Telescope image zooms in on the feathery spiral arms of the galaxy NGC 45, which lies just 22 million light-years away in the constellation Cetus (the Whale).
The portrait uses data drawn from two complementary observing programs. The first took a broad view of 50 nearby galaxies, leveraging Hubble’s ability to observe ultraviolet through visible into near-infrared light to study star formation in these galaxies. The second program examined many of the same nearby galaxies as the first, narrowing in on a particular wavelength of red light called H-alpha. Star-forming nebulae are powerful producers of H-alpha light, and several of these regions are visible across NGC 45 as bright pink-red patches.
These observing programs aimed to study star formation in galaxies of different sizes, structures, and degrees of isolation — and NGC 45 is a particularly interesting target. Though it may appear to be a regular spiral galaxy, NGC 45 is a remarkable type called a low surface brightness galaxy.
Low surface brightness galaxies are fainter than the night sky itself, making them incredibly difficult to detect. They appear unexpectedly faint because they have relatively few stars for the volume of gas and dark matter they carry. In the decades since astronomers serendipitously discovered the first low surface brightness galaxy in 1986, researchers have learned that 30–60% of all galaxies may fall into this category. Studying these hard-to-detect galaxies is key to understanding how galaxies form and evolve, and Hubble’s sensitive instruments are equal to the task.

Dr. Steven “Steve” Platnick stepped down from his role at NASA on August 8, 2025, after more than three decades of public service. Steve began his career at NASA as a physical scientist at Goddard Space Flight Center in 2002. He moved to the Earth Science Division in 2009, where he has served in various senior management roles, including as the Earth Observing System (EOS) Senior Project Scientist. In this role, he led the EOS Project Science Office and continued periodic meetings of the EOS Project Scientists, initiated by Michael King during his tenure. Steve expanded these meetings to include representatives of non-EOS Earth observing missions and representatives from Earth Science Mission Operations (ESMO). In addition, Steve was named Deputy Director for Atmospheres in the Earth Science Division in January 2015 and served in this position until July 2024.
Dr. Steve Platnick Image credit: NASA During his time at NASA, Steve played an integral role in the development, sustainability, and advancement of NASA’s Earth Observing System platforms. From January 2003 – February 2010, Steve served as Deputy Project Scientist for Aqua. In this role, he applied his expertise in theoretical and experimental studies of satellite, aircraft, and ground-based cloud remote sensing to improve algorithms to benefit the data gathered from remote observing systems.
Taking the Lead to Improve Algorithms
Steve was actively involved in the Moderate Resolution Imaging Spectroradiometer (MODIS) Science Team, serving as the MODIS Atmosphere Team Lead. Steve helped advance several key components of the MODIS instrument, which flies on NASA’s Terra and Aqua platforms. He led a team that enhanced, maintained, and evaluated MODIS algorithms that support the Level-2 (L2) Cloud Optical/Microphysical Properties components (e.g., COD06 and MYD06) for MODIS on Terra and Aqua. The algorithms were designed to retrieve thermodynamic phase, optical thickness, effective particle radius, and water path for liquid and ice clouds. The team’s work also contributes to L3 products that address cloud mask, aerosols, clouds, and clear sky radiance for data within 1° grids over one-day, eight-day, and one-month repeat cycles. Under Steve’s leadership, the team also developed L2 products (e.g., MODATML2 and MYDATML2) that include essential atmosphere datasets of samples collected at 5–10 km (3–6 mi) that is consistent with L3 products to ease storage requirements of core atmospheric data.
Steve is also a member of the Suomi-National Polar-orbiting Partnership (Suomi NPP) Atmosphere Team, working on operational cloud optical and microphysical products. In this role, he contributed to algorithm development and refinement for the Cloud Product. In particular, he helped address a critical gap in the Visible Infrared Imaging Radiometer Suite (VIIRS) spectral channel, which was not designed to collect information for carbon dioxide (CO2) slicing and water vapor data in the same way as MODIS. Steve and his colleagues developed a suite of L2 algorithms for the spectral channels that were common to both MODIS and VIIRS to address cloud mask and cloud optical/microphysical properties. Through these efforts, the project has established a continuous cloud data record gathered from both instruments from 2017 to the present.
Steve also participated in numerous other working groups during the past 30 years. He participated in the Global Energy and Water Exchanges (GEWEX) Cloud Assessment Working Group (2008–present), Arctic Radiation-Cloud-Aerosol-Surface Interaction Experiment (ARCSIX) Science Team (2023–present), ObseRvations of Aerosols above CLouds and their intEractionS (ORACLES) Earth–Venture Suborbital (EVS)-2 Science Team (2014–2023), Deep Space Climate Observatory (DSCOVR) Science Team (2014–present), Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Science Team (2014–2023), PACE Science Definition Team, Deputy Chair (2011–2012), Glory Science Team (2010–2014) NASA Observations for Modeling Intercomparison Studies (obs4MIPs) Working Group (2011), Advanced Composition Explorer (ACE) Science Definition Team (2009–2011), and Geostationary Operational Environmental Satellites (GOES) R-series Advanced Baseline Imager (ABI) Cloud Team (2005–2009).
Steve has also participated in numerous major airborne field campaigns in various roles, including: GSFC Lidar Observation and Validation Experiment (GLOVE, 2025), PACE Postlaunch Airborne eXperiment (PAX, 2024), the Westcoast & Heartland Hyperspectral Microwave Sensor Intensive Experiment (WH2yMSIE, 2024), ORACLES Science Team (2015–2019), Studies of Emissions and Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys (SEAC4RS) Science Team (2011–2015), Tropical Composition, Cloud and Climate Coupling (TC4) Management Team (2007), Cirrus Regional Study of Tropical Anvils and Cirrus Layers – Florida Area Cirrus Experiment (CRYSTAL-FACE) Science Management Team (2002), Southern Africa Fire-Atmosphere Research Initiative (SAFARI, 2000), First ISCCP Regional Experiment (FIRE) Arctic Cloud Experiment (ACE) (1998), Mikulski Archive for Space Telescopes (MAST, 1994), and ACE (1992).
Supporting Earth Science Communications
Through his senior leadership roles within ESD Steve has been supportive of the activities of NASA’s Science Support Office (SSO). He has participated in many NASA Science exhibits at both national and international scientific conferences, including serving as a Hyperwall presenter numerous times. He has met with task leaders frequently and has advocated on behalf of the SSO to management at NASA Headquarters, GSFC, and Global Sciences & Technology Inc.
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 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 newsletterfrom 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 Robert H. Goddard Award for Science: MODIS/VIIRS Cloud Products Science Team (2024) and the William Nordberg Memorial Award for Earth Science in 2023. He received the Verner E.

Credit: NASA/Jef Janis This summer, NASA’s Glenn Research Center in Cleveland hosted the NASA Glenn High School Engineering Institute, a free, work-based learning experience designed to prepare rising high school juniors and seniors for careers in the aerospace workforce.
“The institute immerses students in NASA’s work, providing essential career readiness tools for future science, technology, engineering, and mathematics-focused academic and professional pursuits,” said Jerry Voltz of NASA Glenn’s Office of STEM Engagement.
Throughout the five-day sessions (offered three separate weeks in July), students used authentic NASA mission content and collaborated with Glenn’s technical experts. They gained a deeper understanding of the engineering design process, developed practical engineering solutions to real-world challenges, and tested prototypes to address key mission areas such as:
Acoustic dampening: How can we reduce noise pollution from jet engines? Power management and distribution: How can we develop a smart power system for future space stations? Simulated lunar operations: Can we invent tires that don’t use air? NASA Glenn Research Center High School Engineering Institute participants, left to right: Adriana Pudloski, Anadavel Sakthi, Aditya Rohatgi, and Alexa Apshago, make modifications to the control system program for their rover on Friday, July 18, 2025. Credit: NASA/Jef Janis Voltz said he hoped students left the program with three key takeaways: a deeper curiosity and excitement for STEM careers, firsthand insight into how cutting-edge technology developed in Cleveland contributes to NASA’s most prominent missions, and most importantly, a feeling of empowerment gained from engaging with some of NASA’s brightest minds in the field.
