Caltech and JPL researchers identify a process involving UV light from the sun that helps explain how a moderately dense martian atmosphere 3.8 billion years ago could have evolved into the current thin one without invoking a missing carbon reservoir.
On its way to higher layers of the mountain where it is investigating how Mars' environment changed billions of years ago, NASA's Curiosity Mars rover will take advantage of a chance to study some modern Martian activity at mobile sand dunes.
Charles Elachi has announced his intention to retire as director of the Jet Propulsion Laboratory on June 30, 2016 and move to campus as professor emeritus. A national search is underway to identify his successor.
Using data from the W. M. Keck Observatory's OSIRIS spectrometer and maps from NASA's Galileo probe, researchers have mapped what may be salt deposits from the ocean below the ice onto the Jovian moon's surface.
If microbial life exists elsewhere in the solar system, wouldn't we like to actually see it on the move? Bioengineers are already testing a new scope—in extreme environments a bit closer to home—that could capture the 3D videos to make that possible.
In September, the NASA/JPL Cassini mission began the last two years of the Solstice Mission. We recently spoke with JPL director Charles Elachi to gain his unique perspective on Cassini's achievements—and what will come next.
Ken Farley, the project scientist for NASA's next Mars rover, a mission called Mars 2020, and the W.M. Keck Foundation Professor of Geochemistry at Caltech, talks about how the Mars 2020 landing site selection process is shaping up.
