Mars Rover
Fun Irish Humour - Sexy Irish Women Humour
LOS ANGELES - They’re old and dirty, but NASA’s Mars rovers are back in the exploration business after enduring a lengthy Red Planet dust bowl that blocked most of the sunlight they need for power.
With skies gradually brightening, the solar-powered rovers Spirit and Opportunity recently resumed driving and other operations that had been suspended during the dust storm.
“The rovers are in good health and in good shape,” said John Callas, the rover project manager at NASA’s Jet Propulsion Laboratory in Pasadena. “Things have improved from the more dire conditions that were existing previously due to the dust storm on Mars.”
During the storm, each of the rovers spent a couple of weeks sleeping most of the time.
“They were in sort of a hibernation state where we were only communicating with them every few days,” Callas said Friday. “The rovers would only be awake a very short amount of time each day to save power.”
