A NASA airborne instrument captured this false-color image of areas burned by the Eaton fire in Altadena as of January 11, 2025. Burnt trees and buildings in developed areas appear brown; burned wildland areas are orange. go.nasa.gov/3CbCL28

Destination: Moon Our biggest commercial lunar delivery yet is on @fireflyspace’s Blue Ghost lander, set to launch on a @SpaceX Falcon 9 rocket at 1:11am ET (0611 UTC). The science aboard will help prepare for future human missions to the lunar surface. xitter.cf/i/broadcasts/1dRKZdEPo…

We’re delivering loads of cutting-edge science and technology to the Moon aboard @fireflyspace's Blue Ghost 1 mission. Learn more about one of the payloads, NASA’s Lunar PlanetVac, our “lunar vacuum” system designed to transform how we collect and analyze soil samples in space.
A technology demonstration being delivered to the @NASAMoon as part of @NASA’s CLPS initiative could change how teams collect and study soil and rock samples on other planetary bodies. Read more about this lunar vacuum cleaner, known as Lunar PlanetVac >> go.nasa.gov/427hWQ6

Satellites unite on the ocean! 🌊 PACE and SWOT see the ocean differently. But when their data comes together — the physics from SWOT and the biology from PACE — we get a better understanding of what’s happening in the sea.

What didn’t seem possible a few years ago is now within reach. As we celebrate three years since @POTUS issued the Federal Sustainability Plan, we are unlocking the path to cutting the U.S. Government’s emissions and reaching net zero by 2050. tinyurl.com/57t4fvmr
