Description

The search for extraterrestrial life has improved since the discovery of water fountain plumes emanating from icy moons such as Enceladus and Europa. These water jets produce micron and sub-micron ice grains that, according to the Cassini probe contain possible elements indicative of life.nbsp;Under prior NASA support, we have discovered that hypervelocity ice grain impacts into aerogel create a rearward ejecta of water vapor through the impact cone into the surrounding vacuum. Ice seeded with organic molecules survives this impact and can be detected in-situ mass spectrometrically. Unpublished work at the Ames vertical gun range has shown that oblique angle impacts with bacteria can allow the bacteria to survive morphologically. The ability to image with a light microscope and/or SEM in-situ aboard a spacecraft passing through an ice plume would complement any molecular indication of life. nbsp;nbsp;
