NASA engineers are set to take a second go at extricating thestuck rover Spirit from its sandy trap on Mars.
New commands for the rover to attemptto drive out of the sand it is stuck in will be sent up early in themorning on Thursday, according to a NASA report releasted late Wednesday.
Spirit has been mired in the sand pit, dubbed "Troy," since April.
The first attempt to free Spirit, which took place onTuesday, hita snag when the rover sensed it was tilting too much and stopped after lessthan one second of wheel spin.
The new commands have taken the rover's attitude intoaccount. They will again instruct Spiritto drive ahead in two 8.2-feet (2.5-meter) steps. Those distances are theamount of wheel spin the rover will use; the rover is not expected to move verymuch.
The results from this second drive attempt will be beameddown via a Mars orbiter relay later on Thursday. But the relay pass has alimited downlink volume, so the rover team will likely be unable to completetheir analysis that same day.
