Three central Arkansas researchers are working to develop a mobile laboratory system to help NASA search for water on Mars. University of Arkansas at Little Rock professor Gary Anderson and Harding University professor Edmond Wilson received a small grant from the Arkansas Space Grant Consortium to build small robots. The research team now has a few more members and 670 thousand dollars from NASA to work on the nuts and bolts of the project: developing equipment capable of detecting water vapor. The researchers use a robot-mounted spectrometer (spec-TROM`-uh-ter), an instrument that detects chemicals. The researchers aren`t working on a specific NASA mission but they are hoping they can develop technology that NASA can use in the future.
