Spirit Moves on Mars by 1/2 Inch

The Mars Exploration Rover (MER) Spirit moved forward by a mere one-half inch in seeking to gain freedom from a sand trap in which it has been lodged the past six months after commands were sent to from Earth Monday to attempt to extricate itself from sand. The rover wheels are up to the hubcaps in the Martain sand. Mission scientists believe progress has been made in getting the rover free with a one-half inch movement but further analysis is deemed required prior to the next attempted move.
