One of the front wheels on the Mars rover Spirit has stopped working
The Mars rover Spirit project has been going very well for NASA, but one of Spirit’s front wheels has stopped working. Researchers believe that the motor that rotates the wheel is no longer working. The motors that rotate the wheels have worked much longer than the initial mission expected, which may be a reason one of the wheels has failed. The same wheel had problems five months after landing, when it started drawing too much current five months after landing on the Red Planet.
Spirit is again dragging the wheel as it tries to reach a position where it can get as much sunlight as possible during winter, but although the point of minimum sunshine is more than 100 days away, there is already only enough to power about one hour of driving on flat ground per day, JPL said.
The Spirit landed on Mars in January of 2004, and has done a great job gathering information for NASA.
