Heyman Service to America Medals, also known as the Sammies, recognizing outstanding federal employees who are addressing many of our country’s greatest challenges.
Rich Burns of NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and John Blevins of Marshall Space Flight Center in Huntsville, Alabama, were selected out of 350 nominees and are among 23 individuals and teams honored for their achievements as federal employees. They will be recognized at a ceremony in Washington on Tuesday, June 17, that also will be live streamed on the Sammies website. The honorees will be commended via videos and presenter remarks and receive medals for their achievements.
Named after the founder of the Partnership for Public Service, the 2025 Service to America Medals awards celebrate federal employees who provided critical public services and made outstanding contributions to the health, safety, and national security of our country.
“Rich and John exemplify the spirit of exploration and service that defines NASA and our nation’s civil servants,” said acting NASA Administrator Janet Petro. “Their leadership, ingenuity, and dedication have not only advanced America’s space program but also inspired the next generation of innovators. We are proud to see their achievements recognized among the very best of federal service.”
Richard Burns, project manager for the Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer (OSIRIS-REx) at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and honoree of the 2025 Samuel J. Heyman Service to America MedalsCredit: NASA Burns was the project manager of the Origins, Spectral Interpretation, Resource Identification, and Security – Regolith Explorer (OSIRIS-REx) mission to collect a sample from an asteroid and oversaw operations from the developmental stage to the successful landing of the spacecraft’s Sample Return Capsule.
The mission launched on Sept. 18, 2016, and after a nearly four-year journey, the OSIRIS-REx spacecraft successfully collected a sample from the asteroid Bennu on Oct. 20, 2020, which returned to Earth on Sept. 24, 2023, providing scientists with 120 grams of pristine material to study, the largest amount ever collected from an asteroid. Working to solidify OSIRIS-REx as a success, Burns set up multiple partnerships and communicated frequently with scientists, large and small businesses, NASA centers, and others to ensure the mission’s vision was carried out though each phase.
During the mission, Burns had to handle unique challenges that required adapting to new situations. These included improving flight software to help the spacecraft avoid hazardous parts of Bennu’s rocky surface and working with NASA leaders to find a way to best protect the sample collected from Bennu after a large stone propped the collection canister open. Finally, when the sample was set to return to Earth, Burns worked extensively with NASA and military partners to prepare for the landing, focusing on the safety of the public along with the integrity of the sample to ensure the final part of the mission was a success.
Burns helped OSIRIS-REx exceed its objectives all while under the original budget, allowing NASA to share a portion of the sample with more than 80 research projects and make new discoveries about the possible origins of life on our planet. The spacecraft, now known as Origins, Spectral Interpretation, Resource Identification and Security – Apophis Explorer, is scheduled to rendezvous with the asteroid Apophis in 2029.
“It’s humbling to accept an award based on the achievements of the amazingly talented, dedicated, and innovative OSIRIS-REx team,” Burns said. “I consider myself privileged to be counted among a team of true explorers who let no obstacle stand in the way of discovery.”

This included calculating structural needs, thermal analyses of the effects, and studies of vibrations, acoustics, propulsion integration, among other work.
Artemis I, the first test flight of the SLS rocket, successfully launched from NASA’s Kennedy Space Center in Florida on Nov. 16, 2022. In the time leading up to and during launch, Blevins led the team integrating the hardware for the mission working to address unexpected events while SLS was on the pad prior to launch. This included significant lightning storms and two hurricanes impacting Kennedy Space Center in Florida.
Blevins built a working coalition of engineering teams across the agency that previously did not exist. His ability to forge strong relationships on the various teams across the agency allowed for the successful launch of Artemis I. He continues to lead the engineering team behind SLS as they prepare for Artemis II, the second flight of SLS and the first crewed lunar mission of the 21st century.
“This is a reflection on the hard work and dedication of the entire Artemis Team,” Blevins said. “I am working with an incredibly competent, dedicated team agencywide that goes above and beyond to promote the space exploration goals of our nation. I am honored to accept the award on their behalf.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
By Beth Ridgeway
NASA’s Student Launch competition celebrated its 25th anniversary on May 4, just north of NASA’s Marshall Space Flight Center in Huntsville, Alabama, bringing together more than 980 middle school, high school, college, and university students from across the U.S. to showcase and launch their high-powered rocketry designs.
The event marked the conclusion of the nine-month challenge where teams designed, built, and launched more than 50 rockets carrying scientific payloads—trying to achieve altitudes between 4,000 and 6,000 feet before executing a successful landing and payload mission.
“This is really about mirroring the NASA engineering design process,” Kevin McGhaw, director of NASA’s Office of STEM Engagement Southeast Region, said. “It gives students hands-on experience not only in building and designing hardware, but in the review and testing process. We are helping to prepare and inspire students to get out of classroom and into the aerospace industry as a capable and energizing part of our future workforce.”
NASA announced James Madison University as the overall winner of the agency’s 2025 Student Launch challenge, followed by North Carolina State University, and The University of Alabama in Huntsville. A complete list of challenge winners can be found on the agency’s Student Launch webpage.
Participants from James Madison University – the overall winner of the 2025 NASA Student Launch competition – stand around their team’s high-powered rocket as it sits on the pad before launching on May 4 event. NASA/Krisdon Manecke Each year, a payload challenge is issued to the university teams, and this year’s task took inspiration from the agency’s Artemis missions, where NASA will send astronauts to explore the Moon for scientific discovery, economic benefit, and to build the foundation for the first crewed missions to Mars. Teams were challenged to include sensor data from STEMnauts, non-living objects representing astronauts. The STEMnaut “crew” had to relay real-time data to the student team’s mission control, just as the Artemis astronaut crew will do as they explore the lunar surface.
Student Launch is one of NASA’s seven Artemis Student Challenges – activities that connect student ingenuity with NASA’s work returning to the Moon under Artemis in preparation for human exploration of Mars.
The competition is managed by Marshall’s Office of STEM Engagement. Additional funding and support are provided by the Office of STEM Engagement’s Next Generation STEM project, NASA’s Marshall Space Flight Center, the agency’s Space Operations Mission Directorate, Northrup Grumman, National Space Club Huntsville, American Institute of Aeronautics and Astronautics, National Association of Rocketry, Relativity Space, and Bastion Technologies Inc.

2 Min Read NASA Seeks Commercial Feedback on Space Communication Solutions
An illustration of a commercial space relay ecosystem. Credits: NASA / Morgan Johnson NASA is seeking information from U.S. and international companies about Earth proximity relay communication and navigation capabilities as the agency aims to use private industry satellite communications services for emerging agency science missions.
“As part of NASA’s Communications Services Project, the agency is working with private industry to solve challenges for future exploration,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN Program. “Through this effort, NASA missions will have a greater ability to command spacecraft, resolve issues in flight, and bring home more data and scientific discoveries collected across the solar system.”
In November 2024, NASA announced the TDRS (Tracking and Data Relay Satellite) system, the agency’s network of satellites relaying communications from the International Space Station, ground controls on Earth, and spacecraft, will support only existing missions.
NASA, as one of many customers, will obtain commercial satellite services rather than owning and operating a replacement for the existing satellite system. As NASA transitions to commercial relay services, the agency will leverage commercial capabilities to ensure support for future missions and stimulate private investment into the Earth proximity region. Commercial service offerings could become available to NASA missions as early as 2028 and will continue to be demonstrated and validated through 2031.
NASA’s SCaN issued a Request for Information on May 30. Responses are due by 5 p.m. EDT on Friday, July 11.
NASA’s SCaN Program serves as the management office for the agency’s space communications and navigation. More than 100 NASA and non-NASA missions rely on SCaN’s two networks, the Near Space Network and the Deep Space Network, to support astronauts aboard the International Space Station and future Artemis missions, monitor Earth’s weather, support lunar exploration, and uncover the solar system and beyond.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Students from Tropico Middle School in Rosamond, California, build their own paper planes as part of a project during NASA Aero Fair on April 9, 2025.NASA/Genaro Vavuris A new generation of aerospace explorers will soon embark on a hands-on summer experience focusing on careers in science, mathematics, engineering, and technology (STEM). This month, NASA’s Armstrong Flight Research Center in Edwards, California, and the Flight Test Museum Foundation will launch the 2025 Junior Test Pilot School.
Held at Blackbird Airpark and Joe Davies Heritage Airpark in Palmdale, California, this six-week program invites elementary-aged students to step into the shoes of test pilots and engineers from 9 a.m. to 2 p.m. Mondays through Fridays, June 16 through July 25. Registration is free through participating school districts and the Flight Test Museum. Students will have direct access to legendary aircraft such as A-12, SR-71, U-2, F-86 Sabre, and NASA Boeing 747 Space Shuttle Carrier Aircraft.
The Junior Test Pilot School combines authentic NASA-designed curriculum, immersive aerospace activities, and direct engagement with engineers, test pilots, and scientists to inspire future aerospace professionals in the Antelope Valley – home to one of the nation’s highest concentrations of STEM careers.
“This program offers more than a glimpse into aerospace, it provides students a hands-on opportunity to solve real-world problems and see themselves in future STEM roles,” said Dr. Amira Flores, program integration manager for NASA’s California Office of STEM Engagement.
Daily lessons cover eight core modules: flight principles, stealth engineering, altitude effects, speed and g-force, payload impact, maneuverability, reconnaissance design, and jet engine systems.
Additionally, in collaboration with NASA Armstrong’s Aero Fair program, students will be guided through the program’s Wildfire Design Challenge by a NASA volunteer. Following the engineering design process, students will collaborate to design and build a prototype of an aerial vehicle that suppresses wildfires.
“Our junior test pilots learn to analyze the aircraft to figure out why they were designed the way they are and think like an engineer,” said Lisa Sheldon Brown, director of education at the Flight Test Museum. “Research shows that academic trajectory is set by fifth grade, making this the critical window to inspire STEM interest and career awareness.”
The program is delivered in partnership with the City of Palmdale and is supported by industry sponsors, including Lockheed Martin and Northrop Grumman. These partners not only provide funding and volunteers but also elevate career exposure by introducing students to diverse aerospace professionals within the region.
NASA Armstrong is a hub of aeronautical innovation and STEM workforce development in the Antelope Valley. Through programs like Aero Fair and partnerships like Junior Test Pilots School, Armstrong inspires and equips the next generation of engineers, pilots, and scientists.
The Flight Test Museum Foundation preserves the legacy and promotes the future of aerospace through education programs and historical preservation at the Blackbird Airpark and forthcoming Flight Test Museum at Edwards Air Force Base in Edwards, California.

NASA’s TROPICS Mission: Offering Detailed Images and Analysis of Tropical Cyclones
Introduction
Tropical cyclones represent a danger to life, property, and the economies of communities. Researchers who study tropical cyclones have focused on remote observations using space-based platforms to image these storms, inform forecasts, better predict landfall, and improve understanding of storm dynamics and precipitation evolution – see Figure 1.
Figure 1. TROPICS imagery of Typhoon Kong-rey observed on October 29, 2024 near 205 GHz revealing a large and well-defined eye. Figure credit: U.S. Naval Research Laboratory The tropical cyclone community has leveraged data from Earth observing platforms for more than 30 years. These data have been retrieved from numerous instruments including: the Advanced Baseline Imager (ABI) on the National Oceanic and Atmospheric Administration’s (NOAA) Geostationary Operational Environmental Satellite (GOES)–Series R satellites; the Tropical Rainfall Measuring Mission (TRMM) Microwave Imager (TMI); the Global Precipitation Measurement (GPM) Microwave Imager (GMI); the Special Sensor Microwave Imager/Sounder (SSMIS) on the Defense Meteorological Satellite (DSMP) satellites; the Advanced Microwave Scanning Radiometer (AMSR-E) on Aqua; AMSR2 on the Japan Aerospace Exploration Agency’s (JAXA) Global Change Observation Mission–Water (GCOM-W) mission; the Advanced Microwave Sounding Unit (AMSU) on Aqua and the Advanced Technology Microwave Sounder (ATMS) on the NASA–NOAA Suomi National Polar-Orbiting Partnership (Suomi NPP), NOAA-20, and NOAA-21; the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua Platform; and the Visible Infrared Imaging Radiometer Suite (VIIRS) on Suomi NPP, as well as on the first two Joint Polar Satellite System (JPSS) missions (i.e., NOAA-20 and NOAA-21).
Despite having decades of data at their disposal, scientists lack data from instruments placed in low-inclination orbits that provide more frequent views within tropical regions. This limitation is especially pronounced in the tropical and subtropical latitudes, which is where tropical storms develop and intensify.
The NASA Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) grew from the Precipitation and All-weather Temperature and Humidity (PATH) to address a need for obtaining three-dimensional (3D) temperature and humidity measurements as well as precipitation with a temporal revisit rate of one hour or better – see Figure 2. TROPICS uses multiple small satellites flying in a carefully engineered formation to obtain rapid revisits of measurements of precipitation structure within the storms, as well as temperature and humidity profiles, both within and outside of the storms, including the intensity of the upper-level warm core. In addition, the instruments provide a median revisit time of about one hour. The data gathered also informs changes in storm track and intensity and provides data to improve weather prediction models.
The imagery is focused on inner storm structure (near 91 and 205 GHz), temperature soundings (near 118 GHz), and moisture soundings (near 183 GHz). Spatial resolution at nadir is approximately 24 km (16.8 mi) for temperature and 17 km (10.6 mi) for moisture and precipitation, covering a swath of approximately 2000 km (1243 mi) in width. Researchers can use TROPICS data to create hundreds of high-resolution images of tropical cyclones throughout their lifecycle.
Figure 2. TROPICS space vehicle showing the CubeSat bus, radiometer payload, and deployed articulated solar array. Figure credit: Blue Canyon Technologies and MIT Lincoln Laboratory This article provides an overview of the two years of successful science operations of TROPICS, with a focus on the suite of geophysical Level-2 (L2) products (e.g., atmospheric vertical temperature and moisture profiles, instantaneous surface rain rate, and tropical cyclone intensity) and the science investigations resulting from these measurements. The complete article, available in the Proceedings Of The IEEE: Special Issue On Satellite Remote Sensing Of The Earth, provides more comprehensive details of the results.
From Pathfinder to Constellation
A single TROPICS satellite was launched as a Pathfinder vehicle on June 30, 2021, aboard a SpaceX Falcon 9 rideshare into a Sun-synchronous polar orbit. TROPICS was originally conceived as a six-satellite constellation, with two satellites launched into each of three low-inclination orbits. Regrettably, the first launch, on June 22, 2022 aboard an Astra Rocket 3.3, failed to reach orbit. While unfortunate, the mission could still proceed with four satellites and meet its baseline revisit rate requirement (with no margin), with the silver lining of an extra year of data gathered from TROPICS Pathfinder that allowed the tropical cyclone research community to prepare and test communications systems and data processing algorithms before the launch of the four remaining constellation satellites. These satellites were deployed on two separate launches – May 8, 2023 and May 26, 2023 aboard a Rocket Lab launch vehicle. The early testing accelerated calibration and validation for the constellation.
Collecting Data Critical to Understanding Tropical Cyclones
Tropical cyclone investigations require rapid quantitative observations to create 2D storm structure information. The four radiance data products in the TROPICS constellation [i.e., antenna temperature (L1a), brightness temperature (L1b), unified brightness temperature, and regularized scan pattern and limb-adjusted brightness temperature (L1c)] penetrate below the cloud top to gather data at greater frequency for a lower cost than current operational systems. The constellation data has been used to evaluate the development of the warm core and evolution of the ice water path within storms – two indicators of storm formation and subsequent changes in intensity.
The upper-level warm core is key to tropical cyclone development and intensification. Precipitation may instigate rapid intensification through convective bursts that are characterized by expanding cold cloud tops, increasing ice scattering, lightning, and towers of intense rain and ice water that are indicative of strong updrafts. TROPICS frequencies provide a wealth of information on scattering by precipitation-sized ice particles in the eyewall and rainbands that will allow for researchers to track the macrostructure of convective bursts in tropical cyclones across the globe. In addition, TROPICS data helps clarify how variations in environmental humidity around tropical cyclones affect storm structure and intensification.
Upper-level Warm Core
Analysis of the upper-level warm core of a tropical cyclone reveals valuable information about the storm’s development. The tropical cyclone community is using data from TROPICS to understand the processes that lead to precipitating ice structure and the role it plays in intensification – see Figure 3. While the warm core has been studied for decades, TROPICS provides a new opportunity to get high-revisit rate estimates of the atmospheric vertical temperature profile. By pairing the temperature profile with the atmospheric vertical moisture profile, researchers can define the relative humidity in the lower-to-middle troposphere, which is critical to understanding the impact of dry environmental air on storm evolution and structure.
Figure 3. TROPICS-3 imagery of Typhoon Kong-rey observed on October 29, 2024, a Category-5 storm that formed in the Pacific Ocean basin. Data gathered near 118 GHz was used to characterize temperature while data gathered near 205 GHz [right] revealed more about the inner structure of the storm. These data are used to define the warm core of the well-defined eye, located at 18.5° N. Figure Credit: U.S. Naval Research Laboratory Ice Water Path and Precipitation
Another variable that helps to provide insight into the development of tropical cyclones is the ice water path, which details the total mass of ice present in a vertical column of the atmosphere and is therefore useful for characterizing the structure and intensity of these storms. Increasing ice water path can reflect strengthening convection within a storm and thereby be an indicator of likely intensification – see Figure 4. TROPICS is the first spaceborne sensor equipped with a 205-GHz channel that, along with the traditional 89, 118, and 183 GHz channels, is more sensitive to detecting precipitation-sized ice particles. In addition, the TROPICS Precipitation Retrieval and Profiling Scheme (PRPS) provides an estimate of precipitation. This scheme is based solely on the satellite radiances linked to precipitation rates, which can be used to generate products across time scales, from near-real-time to climatological scales.
Figure 4. Global precipitation ice water path (PIWP) retrievals derived from TROPICS [top] compared to those derived using data from the GPM Dual-frequency Precipitation Radar (GPM DPR) [bottom] The strong agreement between the two datasets is further validated through case studies over hurricanes, where TROPICS observations correspond well with known storm characteristics. Figure Credit: Blackwell, W. J. et al. (2025) Collaborations and TROPICS Data in Action
To evaluate and enhance the data gathered by TROPICS, the TROPICS application team enlisted the assistance of operational weather forecasters that formed the TROPICS Early Adopters program. In 2018, the program connected the application team to stakeholders interested in using TROPICS data for research, forecasting, and decision making. This collaboration improved approaches to diagnose and predict tropical cyclones. For example, the National Hurricane Center (NHC) found that the new TROPICS channel at 204.8 GHz offered the best approach to capture convective storm structure, followed by the more traditionally used 91-GHz channel. In addition, the U.S. Joint Typhoon Warning Center (JTWC) has been using TROPICS data to center-fix tropical cyclones and identify cloud formations. In particular, the JTWC team found that the 91-GHz channel was most useful for identifying cloud structure. Both NHC and JTWC found the TROPICS high revisit rate to be beneficial.
In 2024, the TROPICS applications team developed the TROPICS Satellite Validation Module as part of the NOAA Hurricane Research Division’s annual Advancing the Prediction of Hurricanes Experiment (APHEX). The module coordinated data collection from NOAA’s Hurricane Hunter aircraft beneath TROPICS satellite overpasses to provide data to calibrate and validate TROPICS temperature, moisture, and precipitation measurements. Using this approach, the Hurricane Hunter team tracked Hurricane Ernesto over the central North Atlantic on August 15 and 16, 2024 and used the data to characterize the environment of Ernesto’s rain bands – see Figure 5.
Figure 5. Brightness temperature (K) measured at 205 GHz from TROPICS-5 [right] and TROPICS-6 [left and center] from Hurricane Ernesto on August 15 and 16, 2024. The shaded circles denote 850–700 hPa relative humidity (%). Wind barbs are 850–700 hPa layer averaged winds (kt). Dropsonde data within 30 minutes of the TROPICS overpass times are plotted. Figure Credit: Blackwell, W. J. et al. (2025) In addition, the team used TROPICS observations in combination with GPM constellation precipitation estimates to characterize the lifecycle of Hurricane Franklin, which formed on August 19, 2023 and underwent a period of rapid intensification about eight days later. Intensification of the storm, in particular the period of rapid intensification (45 knot increase in maximum winds in 24 hours), occurred in association with a decrease in environmental vertical wind shear, a contraction of the radius of maximum precipitation, and an increase in the precipitation rate. Intensification ended with the formation of secondary rainbands and an outward shift in the radius of maximum precipitation.
Conclusion
TROPICS data offer the potential for improving forecasts from numerical weather prediction models and operational forecasts using its high spatial resolution and high revisit rates that enable enhanced characterization of tropical cyclones globally. To date, the TROPICS mission has produced a high-quality aggregate data record spanning 10 billion observations and 10 satellite years, using relatively low-cost microwave sounder constellations. All L1 (i.e., radiances) and L2 (i.e., geophysical products) data products and Algorithm Theoretical Basis Documents are available to the general public through the Goddard Earth Sciences Data and Information Services Center (GES DISC). The GES DISC data discussed in this article include L1 and L2 products for TROPICS-1, TROPICS-3, TROPICS-5, and TROPICS-6.
TROPICS data has aided hurricane track forecasting for multiple storms as forecasters have used the data at multiple operational tropical cyclone forecast centers. Data gathered by TROPICS will soon be complemented by multiple commercial constellations that are coming online to improve the revisit rate and performance.
