Twenty years have now passed since a seven-man rocketed into the night to begin the second servicing mission to the $1.5 billion Hubble Space Telescope (HST). Coming on the heels of the ambitious STS-61 shuttle flight in December 1993—during […]

A Martian Paradox: Curiosity Rover Findings Raise New Questions About Water on Ancient Mars

View from Curiosity of the Yellowknife Bay rock formation. Drilled samples here and elsewhere provided evidence that this region used to be at the bottom of a lake, but also that there are little or no carbonate mineral deposits, which should have been produced if the carbon dioxide atmosphere was thicker and warmer billions […]
