Spirit rover takes detour for winter

NASA’s Spirit rover is being forced to winter in an alternate location because a broken wheel has slowed the Martian vehicle down so much that it can’t reach its intended spot before winter hits, according to NASA. The rover needs to spend the planet’s dark, cold winter months on a north-facing slope so its solar panels can get enough energy to power it. And with the Martian winter approaching, getting the rover to a safe location has taken precedence over scientific research, principal investigator and Cornell University geologist Steve Squyres said in a statement.
