Ohio lab tests generators for Mars rovers


DAYTON, Ohio (AP) — A research laboratory in Ohio is simulating extreme day and night temperatures in Mars to test the power generators used in NASA'S Mars rover.

Researchers at the University of Dayton were chosen to test to the performance of the generators on the Curiosity Mars rover as part of an ongoing five-year, $3.75 million contract with the U.S. Department of Energy.

The Dayton Daily News (http://bit.ly/1jHnG4m ) reports that the two Multi-Mission Radioisotope Thermoelectric Generators being tested at UD's Research Institute lab are the only ones on Earth. A third is powering the Curiosity rover on Mars.

The generator is the power system used to recharge the batteries on the Curiosity rover.

University officials dedicated the new testing laboratory on Tuesday.
