NASA Uses New Technology to Understand California Wildfires

NeRD

3 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) The Compact Fire Infrared Radiance Spectral tracker, or C-FIRST, is managed an operated by NASA’s Jet Propulsion Laboratory, and supported by NASA’s Earth Science Technology Office. Combining state-of-the-art imaging technology with a compact design, C-FIRST enables scientists to gather data about fires and their impacts on ecosystems with greater accuracy and speed than other instruments. C-FIRST was developed as a spaceborne instrument, and flew onboard NASA’s B200 aircraft in January 2025 to conduct an airborne test. NASA/JPL-Caltech The January…

Meet NASA Women Behind World’s Largest Flying Laboratory

NeRD

5 min read Preparations for Next Moonwalk Simulations Underway (and Underwater) NASA’s DC-8 aircraft – the world’s largest flying science laboratory – began its science missions in 1987 and since then, has flown in service of the science community over places like Antarctica, Greenland, and Thailand. Aircraft like the DC-8 have enabled scientists to ask questions about life on Earth and explore them in a way that only NASA’s Airborne Science program can make happen. After 37 years, the DC-8 will retire to Idaho State University, where it will serve…

Can Volcanic Super Eruptions Lead to Major Cooling? Study Suggests No

NeRD

Some 74,000 years ago, the Toba volcano in Indonesia exploded with a force 1,000 times more powerful than the 1980 eruption of Mount St. Helens. The mystery is what happened after that – namely, to what degree that extreme explosion might have cooled global temperatures. Crew aboard the International Space Station photographed the eruption of Mount Etna in Sicily in October 2002. Ashfall was reported more than 350 miles away. When it comes to explosive power, however, no eruption in modern times can compare with a super eruption – which…
