UPDATE Feb. 11, 2025: The second rocket of the GIRAFF mission launched on Saturday, Feb. 8, at 11:35 p.m. Alaska Standard Time, through pulsating aurora over Venetie, Alaska. The principal investigator reported that all of the instruments looked healthy. The Black…
For decades, scientists have tried in vain to accurately predict solar flares — intense bursts of light on the Sun that can send a flurry of charged particles into the solar system. Now, using NASA’s Solar Dynamics Observatory, one team…
Firefly's Blue Ghost 3 lander will deliver six NASA science payloads to the Gruithuisen Domes.
NASA's DAVINCI probe will be first in the 21st century to brave Venus’ atmosphere as it descends from above the planet down to its surface.
Scientists find that cometary dust affects interpretation of spacecraft measurements, reopening the case for comets like 67P as potential sources of water for early Earth. Researchers have found that water on Comet 67P/Churyumov–Gerasimenko has a similar molecular signature to the…
A.63 Ecohydrology is a special program element of the NASA Terrestrial Hydrology Program in recognition of the need for holistic, interdisciplinary approaches to evaluate and refine modeled coupled water, energy and carbon cycle process representation in a manner that more…
