The Hubble Space Telescope has completed observations of Mars using the
Space Telescope Imaging Spectrograph. Observations were made of the highly
extended upper atmosphere and the UV airglow of Mars - something that has
not been studied by any in situ spacecraft since Mariner 9 in 1972. The
present-day D/H ratio gives vital information leading to understanding the
evolution of Mars' atmosphere, the historic escape of water into space, and
potentially the remaining water abundance on Mars.
