By Air and by Sea: Validating NASA’s PACE Ocean Color Instrument

In autumn 2024, California’s Monterey Bay experienced an outsized phytoplankton bloom that attracted fish, dolphins, whales, seabirds, and – for a few weeks in October – scientists. A team from NASA’s Ames Research Center in Silicon Valley, with partners at the University of California, Santa Cruz (UCSC), and the Naval Postgraduate School, spent two weeks […]

NASA Tech to Use Moonlight to Enhance Measurements from Space

NASA will soon launch a one-of-a-kind instrument, called Arcstone, to improve the quality of data from Earth-viewing sensors in orbit. In this technology demonstration, the mission will measure sunlight reflected from the Moon— a technique called lunar calibration. Such measurements of lunar spectral reflectance can ultimately be used to set a high-accuracy, universal standard for […]

NASA Launching Rockets Into Radio-Disrupting Clouds

NASA is launching rockets from a remote Pacific island to study mysterious, high-altitude cloud-like structures that can disrupt critical communication systems. The mission, called Sporadic-E ElectroDynamics, or SEED, opens its three-week launch window from Kwajalein Atoll in the Marshall Islands on Friday, June 13. The atmospheric features SEED is studying are known as Sporadic-E layers, […]

NASA Kennedy Digs Latest Robot Test

NASA’s RASSOR (Regolith Advanced Surface Systems Operations Robot) undergoes testing to extract simulated regolith, or the loose, fragmental material on the Moon’s surface, inside of the Granular Mechanics and Regolith Operations Lab at the agency’s Kennedy Space Center in Florida on May 27. Ben Burdess, mechanical engineer at NASA Kennedy, observes RASSOR’s counterrotating drums digging […]

How Do We Do Research in Zero Gravity? We Asked a NASA Expert: Episode 62

How do we do research in zero gravity? Actually when astronauts do experiments on the International Space Station, for instance, to environment on organisms, that environment is actually technically called microgravity. That is, things feel weightless, but we’re still under the influence of Earth’s gravity. Now, the very microgravity that we’re trying to study up […]

NASA’s Dragonfly Mission Sets Sights on Titan’s Mysteries

When it descends through the thick golden haze on Saturn’s moon Titan, NASA’s Dragonfly rotorcraft will find eerily familiar terrain. Dunes wrap around Titan’s equator. Clouds drift across its skies. Rain drizzles. Rivers flow, forming canyons, lakes and seas.  But not everything is as familiar as it seems. At minus 292 degrees Fahrenheit, the dune […]

What NASA Is Learning from the Biggest Geomagnetic Storm in 20 Years

One year on, NASA scientists are still making huge discoveries about the largest geomagnetic storm to hit Earth in two decades, the Gannon storm. The findings are helping us better understand and prepare for the ways in which the Sun’s activity can affect us. One year ago today, representatives from NASA and about 30 other […]
