4 min read NASA Satellites Reveal Abrupt Drop in Global Freshwater Levels Earth (ESD) Earth Home Explore Climate Change Science in Action Multimedia Data For Researchers GRACE satellites measure gravity as they orbit the planet to reveal shifting levels of water on the Earth (artist’s concept). NASA/JPL-Caltech An international team of scientists using observations from NASA-German satellites found evidence that Earth’s total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. Reporting in Surveys in Geophysics, the researchers suggested the shift could indicate Earth’s continents have entered a persistently …

Parallels between spaceflight and the aging process may extend to encompass frailty. Figure Left: Venn diagram of differentially expressed frailty genes in rodent and human samples shows the common differentially expressed genes between the two species. Figure Right: Schematic of the Inspiration4 experiments and samples. This study relied on data from the OSDR, including 7 rodent spaceflight datasets, 2 human space analog datasets, astronaut data from the Japan Aerospace Exploration Agency (JAXA) and Inspiration4. Data on sarcopenia were mined from National Center for Biotechnology Information’s Gene Expression Omnibus. Spaceflight accelerates the symptoms of aging in a…

Credit: NASA NASA, on behalf of the National Oceanic and Atmospheric Administration (NOAA), has selected Southwest Research Institute of San Antonio to build three coronagraphs for the Lagrange 1 Series project, part of NOAA’s Space Weather Next program. Once operational, the coronagraphs will provide critical data to NOAA’s Space Weather Prediction Center, which issues forecasts, warnings, and alerts that help mitigate space weather impacts, including electric power outages and interruption to communications and navigation systems. This cost-plus-fixed-fee contract is valued at approximately $60 million, and the anticipated period of performance is from this No…

In the unforgiving lunar environment, the possibility of an astronaut crewmember becoming incapacitated due to unforeseen circumstances (injury, medical emergency, or a mission-related accident) is a critical concern, starting with the upcoming Artemis III mission, where two astronaut crewmembers will explore the Lunar South Pole. The Moon’s surface is littered with rocks ranging from 0.15 to 20 meters in diameter and craters spanning 1 to 30 meters wide, making navigation challenging even under optimal conditions. The low gravity, unique lighting conditions, extreme temperatures, and availability of only one person to perform the rescue, further complicate any rescue eff…

In November 1969, Apollo 12 astronauts Commander Charles “Pete” Conrad, Command Module Pilot (CMP) Richard F. Gordon, and Lunar Module Pilot (LMP) Alan L. Bean completed the second crewed lunar landing mission. Conrad and Bean achieved a pinpoint landing in the Ocean of Storms within walking distance of the Surveyor 3 spacecraft that landed there in April 1967. While Gordon conducted science from lunar orbit, Conrad and Bean completed two spacewalks on the lunar surface, deploying science instruments, collecting geology samples, and inspecting Surveyor including retrieving several of it parts for study back on Earth. Preparations continued for the next two missions, Apoll…

As the agency continues to explore for the benefit of all, NASA is in the process of searching for a new headquarters facility in Washington or the immediate surrounding area. The current NASA Headquarters lease expires in August 2028, and the agency already has evaluated multiple options including leasing or purchasing within the District of Columbia. Through a request for information published Thursday, NASA took a small step in a longer process to determine the best outcome for the agency and U.S. taxpayers. “With a new facility on the horizon, NASA has a unique opportunity to better meet the needs of a new generation of explorers, discoverers, and public serva…
