The atmospheres of the terrestrial planets have evolved                    markedly over the past 4.5 billion years since the solar system                 formed out of a cloud of interstellar dust and gas.  Venus                      appears to have lost an ocean of water by thermal escape from the               planet, leaving behind traces of water highly enriched in                       Deuterium.  The influx of small comets is a source of water for                 Venus, EArth, and Mars, and measurements of the present water                   content of the Martian atmosphere places severe limits on the                   influx rate of such comets.  This award is for studies of                       evolution of the atmosphere of the terrestrial planets, including               spectroscopic observations of hydrogen escaping from the Earth                  and from cometary nuclei.
