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.
If you ask Andy Ingersoll how Caltech has contributed to our understanding of the universe, he'll tell you, "Caltech invented planetary science!" Since the field's origins 50 years ago, Caltech has become one of the top planetary-science research centers.
A Caltech-led team of Mars Science Laboratory scientists has found that a surprisingly Earth-like martian rock offers new insight into the history of Mars's interior and suggests parts of the red planet may be more like our own than we ever knew.
Bruce Churchill Murray, Caltech Professor of Planetary Science, Emeritus, and former head of NASA's Jet Propulsion Laboratory (JPL), succumbed to complications of Alzheimer's disease on August 29, 2013. He was 81.
John Grotzinger, Caltech’s Fletcher Jones Professor of Geology and project scientist for Curiosity—JPL’s newest Mars rover, exploring the floor of Gale Crater—will describe its discoveries so far during a free public lecture on Wednesday, April 24.
An ankle- or hip-deep stream once flowed with force across the surface of Mars in the very spot where the Curiosity rover is currently exploring. The finding provides new information about a once wet environment in Gale Crater.
