NASA is inviting the public to choose an area in northern Arizona where explorers will conduct part of the annual Desert Research and Technology Studies, known as Desert RATS. "Desert RATS is an annual test where NASA takes equipment and crews into the field to simulate future planetary exploration missions," said Joe Kosmo, Desert RATS manager at NASA's Johnson Space Center in Houston. "We want the public to be a part of this."

From July 27 through Aug. 8, space enthusiasts can vote where to send the Desert RATS team, which includes engineers, scientists and astronauts. To cast your vote, visit: http://desertrats2010.arc.nasa.gov

The website features interactive panoramic images of lava, rocks and desert for the public to choose as the most interesting destination to explore. The location that receives the most votes will be announced Aug. 16. Astronauts will visit that site to perform field geology and collect rock samples.
