      NASA The Moon’s light is refracted by Earth’s atmosphere in this April 13, 2025, photograph from the International Space Station as it orbited into a sunset 264 miles above the border between Bolivia and Brazil in South America.
      Understanding the Moon helps us understand other planets, how they have evolved and the processes which have shaped their surfaces. It also helps us understand the influence the Moon has had on Earth, the record of the ancient Sun, and it serves as a platform to study the rest of the universe. By using the Moon as our closest testing ground for robotics and instrument systems, we can further human exploration to not only the Moon, but the rest of the solar system.
      Through Artemis missions, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars.

      NASA’s X-59 quiet supersonic research aircraft sits on the ramp at Lockheed Martin Skunk Works in Palmdale, California during sunrise, shortly after completion of painting in December 2023.Credit: NASA/Steve Freeman As we observe National Aviation Day Tuesday – a tribute to Orville Wright’s birthday – let’s reflect on both America’s and NASA’s aviation heritage and share how we are pushing the boundaries of flight for the nation’s future. Modern NASA grew from the National Advisory Committee for Aeronautics (NACA), an agency created by Congress in 1915 to advance U.S. aviation. When President Eisenhower signed the National Aeronautics and Space Act of 1958, NACA was dissolved and its people, laboratories and research programs became the foundation of NASA. These intrepid men and women are the cornerstone of the world’s most capable aerospace industry and their legacy lives on today across all facets of the agency.
      The most significant aviation milestones in the twentieth century were achieved through both NASA and NACA research and through the courage of pioneering test pilots. In 1947, the joint NACA/U.S. Army Air Forces (later the U.S. Air Force, or USAF) developed Bell X‑1 flew faster than the speed of sound, shattering the mythical “sound barrier.” This breakthrough, enabled by NACA wind-tunnel data and high-speed aerodynamic expertise, made supersonic flight a reality and led directly to NACA Test Pilot Scott Crossfield being the first human to reach Mach 2, twice the speed of sound, in the Douglass DD558-II a mere six years later. During the X‑15 program of the 1960s, legendary NASA Test Pilots Joe Walker, John McKay, Neil Armstrong, Milt Thompson, and Bill Dana piloted nearly half of the program’s sorties and flew the rocket-powered research plane at altitudes up to 354,200 feet and speeds of 4,520 mph (Mach 6.7).
      The NASA/USAF-developed North American X‑15 became the world’s first reusable hypersonic aerospace vehicle, reaching space (above 50 miles altitude) on 11 separate missions; it provided essential data on materials, flight control and pilot physiology that helped shape the agency’s Mercury, Gemini, Apollo and Space Shuttle programs. These milestones remind us that our nation’s accomplishments are the result of visionary NASA, Department of Defense, industry engineers, and test pilots working together to achieve audacious goals.
      NASA’s commitment to aviation innovation did not stop with early experimental high-speed aircraft. In the 1990s, the U.S. general aviation industry faced a steep decline – production fell from 18,000 aircraft in 1978 to fewer than 1,000 in 1993. NASA saw an opportunity: we envisioned a Small Aircraft Transportation System in which safe, efficient general aviation planes could revitalize a critical industry. To enable that vision, NASA partnered with the Federal Aviation Administration, industry, universities, and non‑profits to create the Advanced General Aviation Transport Experiments (AGATE) consortium in 1994. The AGATE consortium developed safer cockpit displays, crashworthiness improvements, efficient airfoils, and modern manufacturing techniques. These innovations transformed U.S. general aviation, helping spawn industry successes like the Cirrus SR20 and SR22 family of aircraft, which incorporate NASA-derived composite structures and safety features.
      In 2004, NASA’s unmanned X‑43A Hyper-X broke world speed records for air‑breathing aircraft, flying at Mach 6.8 and later Mach 9.6. Those flights demonstrated practical scramjet propulsion and proved that hypersonic cruise flight is achievable.
      Today, we are building on this legacy and pushing the envelope with the X-59. Later this year, NASA Test Pilot Nils Larson will usher in a new era of quiet supersonic flight when he pilots the X‑59 Quesst’s first flight out of NASA’s Armstrong Flight Research Center in Edwards, California. The experimental aircraft, designed to fly at 1.4 times the speed of sound while producing only a gentle sonic “thump” instead of the traditional loud sonic boom, will provide data vital to achieving the vision in President Donald J. Trump’s Executive Order “Leading the World in Supersonic Flight.”
      Hypersonics research is another pillar to our 21st‑century vision. Lessons from the X‑15, X‑43, and Space Shuttle inform our study of high-temperature materials, flight controls and propulsion. These technologies will not only bolster national security but will also spur the development of ultrafast civil transports, shrinking the world even further. We are also investing in 21st century propulsion, additive manufacturing, and autonomy for light aircraft while also developing advanced air traffic control systems. Partnering with U.S. aerospace industry and the FAA, we will bring true 21st century technology into light general aviation aircraft, ensuring America remains at the forefront of aviation innovation.
      I am continually inspired by the ingenuity of our past and the promise of our future. Our roots in NACA remind us that a small group of dedicated men and women can change the world. From the Wright brothers’ pioneering work to the supersonic and hypersonic records set by NASA pilots and vehicles, we have consistently expanded the boundaries of what is possible in flight. Looking ahead, our pursuit of quiet supersonic aircraft, hypersonic technologies, and revitalized general aviation will keep the U.S. aviation industry strong and sustainable for decades to come. On National Aviation Day, we celebrate not only our history but also the teamwork and vision that will carry us into the next century of flight.
      Higher, Farther, Faster!

      A collaboration between NASA and the small business Aloft Sensing produced a new compact radar system that will enable researchers to leverage High Altitude Long Endurance (HALE) platforms to observe dynamic Earth systems. This new radar is small, provides highly sensitive measurements, and doesn’t require GPS for positioning; eventually, it could be used on vehicles in space.
      HALE InSAR flies aboard a high-altitude balloon during a test-flight. This lightweight instrument will help researchers measure ground deformation and dynamic Earth systems. Credit: Aloft Sensing Long before a volcano erupts or a mountainous snowpack disappears, millimeter-scale changes in Earth’s surface indicate larger geologic processes are at work. But detecting those minute changes, which can serve as early warnings for impending disasters, is difficult.
      With support from NASA’s Earth Science Technology Office (ESTO ) a team of researchers from the small aerospace company Aloft Sensing is developing a compact radar instrument for observing Earth’s surface deformation, topography, and vegetation with unprecedented precision.
      Their project, “HALE InSAR,” has demonstrated the feasibility of using high-altitude, long-endurance (HALE) vehicles equipped with Interferometric Synthetic Aperture Radar (InSAR) to observe changes in surface deformation mere millimeters in size and terrain information with centimetric vertical accuracy.
      “It’s a level of sensitivity that has eluded traditional radar sensors, without making them bulky and expensive,” said Lauren Wye, CEO of Aloft Sensing and principal investigator for HALE InSAR.
      HALE vehicles are lightweight aircraft designed to stay airborne for extended periods of time, from weeks to months and even years. These vehicles can revisit a scene multiple times an hour, making them ideal for locating subtle changes in an area’s geologic environment.
      InSAR, a remote sensing technique that compares multiple images of the same scene to detect changes in surface topography or determine structure, is also uniquely well-suited to locate these clues. But traditional InSAR instruments are typically too large to fly aboard HALE vehicles.
      HALE InSAR is different. The instrument is compact enough for a variety of HALE vehicles, weighing less than 15 pounds (seven kilograms) and consuming fewer than 300 watts of power, about as much energy as it takes to power an electric bike.
      HALE InSAR leverages previously-funded NASA technologies to make such detailed measurements from a small platform: a novel electronically steered antenna and advanced positioning algorithms embedded within an agile software-defined transceiver. These technologies were developed under ESTO’s Instrument Incubation Program (IIP) and Decadal Survey Incubation (DSI) Program, respectively.
      “All of the design features that we’ve built into the instrument are starting to showcase themselves and highlight why this payload in particular is distinct from what other small radars might be looking to achieve,” said Wye.
      One of those features is a flat phased array antenna, which gives users the ability to focus HALE InSAR’s radar beam without physically moving the instrument. Using a panel about the size of a tablet computer, operators can steer the beam electronically, eliminating the need for gimbles and other heavy components, which helps enable the instrument’s reduced size and weight.

Credit: Aloft Sensing “SAR needs to look to the side. Our instrument can be mounted straight down, but look left and right on every other pulse such that we’re collecting a left-looking SAR image and a right-looking SAR image essentially simultaneously. It opens up opportunities for the most mass-constrained types of stratospheric vehicles,” said Wye.
      Using advanced positioning algorithms, HALE InSAR also has the unique ability to locate itself without GPS, relying instead on feedback from its own radar signals to determine its position even more accurately. Brian Pollard, Chief Engineer at Aloft Sensing and co-investigator for HALE InSAR, explained that precise positioning is essential for creating high-resolution data about surface deformation and topography.
      “SAR is like a long exposure camera, except with radio waves. Your exposure time could be a minute or two long, so you can imagine how much smearing goes on if you don’t know exactly where the radar is,” said Pollard.
      Navigating without GPS also makes HALE InSAR ideal for field missions in austere environments where reliable GPS signals may be unavailable, increasing the instrument’s utility for national security applications and science missions in remote locations.
      The Aloft Sensing team recently achieved several key milestones, validating their instrument aboard an airship at 65,000 feet as well as small stratospheric balloons. Next, they’ll test HALE InSAR aboard a fixed wing HALE aircraft. A future version of their instrument could even find its way into low Earth orbit on a small satellite.
      Wye credits NASA support for helping her company turn a prototype into a proven instrument.
      “This technology has been critically enabled by ESTO, and the benefit to science and civil applications is huge,” said Wye. “It also exemplifies the dual-use potential enabled by NASA-funded research. We are seeing significant military interest in this capability now that it is reaching maturity. As a small business, we need this hand-in-hand approach to be able to succeed.”

      The weight of the gods was crushing, their toil beyond endurance. Let the burden pass to humankind! So speak the oldest verses carved into clay, a fragment from the Atrahasis tale of Mesopotamia. Yet what if these divine figures were not simply legends? What if the stories hint at something far older and stranger than we have allowed ourselves to believe? The name Anunnaki comes from the etched symbols of Sumerian records, their lines recounting the deeds of deities who shaped the world and watched over the Earth. 

      From the cradle of ancient Mesopotamia comes a story older than any empire, etched into clay tablets and whispered through time: the tale of the Anunnaki. Were they gods, symbols, or something far stranger visitors from beyond the stars who shaped human civilization? The myths of Sumer speak of creation, rebellion, giants, and a great flood. But when paired with the ancient astronaut theory, these legends take on a new dimension, one that could rewrite human history.  
      Who were the Anunnaki? In the ancient Sumerian texts of Mesopotamia, they are described as the offspring of An, the sky god, and Ki, the earth goddess. Their names appear across the Atrahasis epic, the Enuma Elish, the Epic of Gilgamesh, and the Sumerian King List, etched into clay tablets more than 4,000 years ago. 
      To mainstream historians, the Anunnaki are mythological gods. Yet in the ancient astronaut theory, they were real beings, extraterrestrial visitors who shaped early civilization. 
      Author Zecharia Sitchin popularized the idea that the Anunnaki came from Nibiru, a hidden “twelfth planet” on a long, elliptical orbit. According to his interpretation of Sumerian records, the Anunnaki faced an environmental crisis. Their planet’s atmosphere was failing, and the solution they sought was gold, which could be ground into particles and suspended as a shield. 
      This quest for survival brought them to Earth more than 400,000 years ago. They mined resources, altered life, and may even have engineered humanity itself. 
      The tablets describe how the lesser gods, the Igigi, were forced into back-breaking labor until they rebelled. To replace them, the Anunnaki created humans. 
      In myth, mankind was formed from clay mixed with divine blood. In Sitchin’s interpretation, this was genetic engineering: the fusion of Anunnaki DNA with Homo erectus. The first prototype was Adamu, a name that echoes the biblical Adam. 
      The Sumerian “Edin,” later mirrored in the Hebrew Eden, may not have been a paradise garden but an Anunnaki laboratory outpost. 
      Two Anunnaki brothers shaped humanity’s destiny: Enki – the god of wisdom and waters, often seen as humanity’s ally, granting knowledge. Enlil – stern and authoritarian, seeking control and fearing that humans might grow too powerful. Their rivalry runs through Mesopotamian myth, influencing stories of divine punishment, survival, and human struggle. 
      Over time, some Anunnaki defied the rules and took human women as partners. Their offspring were the Nephilim, giants and “mighty men of renown.” The Book of Enoch calls their fathers the Watchers, led by Shemyaza.  
      According to the stories, these hybrids grew violent, corrupted the world, and became uncontrollable. The solution was drastic: a great flood to wipe the Earth clean. 
      The Atrahasis epic, the story of Utnapishtim in the Epic of Gilgamesh, and the biblical Noah all describe the same event: a chosen man warned by a god, a vessel built to preserve life, animals carried aboard, and birds released to find land. Humanity survived, but weaker, with shorter lifespans, and forever changed. 
      Supporters of the ancient astronaut theory believe the Anunnaki left traces in stone: 
      Mesopotamian ziggurats – described as “bonds between heaven and earth,” possibly landing platforms. 
      The Great Pyramid of Giza – aligned to true north, massive in scale, theorized as a power plant or beacon rather than a tomb. 
      Megalithic monuments worldwide – stone circles, cyclopean walls, and sacred sites possibly linked to Anunnaki influence. 
      The Sumerian King List also suggests a divine legacy, describing rulers with lifespans of thousands of years, perhaps evidence of semi-divine hybrids. 
      Mainstream archaeology sees the Anunnaki as symbolic deities, metaphors for cosmic order and human struggle. But in alternative history, they were real beings, extraterrestrial visitors from Nibiru, who shaped civilization, taught astronomy, metallurgy, agriculture, and law, and left their mark in myths and monuments that endure to this day. 
      Explore the mystery of the Anunnaki—Sumerian gods, Nibiru, genetic engineering, Nephilim, the Great Flood, and the ancient astronaut theory in the video below.

      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. Suomi Award from the American Meteorological Society (AMS) in 2016 and was named an AMS Fellow that same year.
      Steve has received numerous NASA Group Achievement Awards, including for the Cloud, Aerosol and Monsoon Processes Philippines Experiment (CAMP2Ex) Field Campaign Team (2020), Fire Influence of Regional to Global Environments and Air Quality (FIREX-AQ) Field Campaign Team (2020), ORACLES Field Campaign Team (2019), obs4MIPs Working Group (2015), SEAC4RS Field Campaign Team (2015), Advanced Microwave Scanning Radiometer for EOS (AMSR-E) Instrument Recovery Team (2013), Climate Absolute Radiance and Refractivity Observatory (CLARREO) Mission Concept Team (2012), Earth Science Constellation Red Team (2011), Science Mission Directorate ARRA Team (2011), TC4 Team (2009), MODIS Science Data Support Team (2007), Aqua Mission Team (2003), CRYSTAL-FACE Science Team (2003), and SAFARI 2000 International Leadership Team (2002).
      Steve received two NASA Agency Honor Awards – the Exceptional Service Medal in 2015 and the Exceptional Achievement Medal in 2008. He was also part of the NASA Agency Team Excellence Award in 2017 for his work with the Satellite Needs Assessment Team. The Laboratory for Atmospheres honored him with the Best Senior Author Publication Award in 2001 and the Scientific Research Peer Award in 2005.
      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. He began his career at the Joint Center for Earth Systems Technology (JCET) at University of Maryland Baltimore County in 1996 as a research associate professor. He held this appointment until 2002.
