Earth-Based Telescopes Search for Martian Water
SUMMARY: Astronomers are searching for evidence of past water on Mars from the comfort of an observatory in Hawaii. They're using the United Kingdom Infrared Telescope (UKIRT) to map the spectral signature given off of minerals on the Red Planet's surface. They're looking for minerals, such as hydrated clay, which would indicate the past presence of liquid water. NASA's two Mars Exploration Rovers will be searching for similar signs on Mars when they arrive in January 2004.
