SPACE, SPACE: This image released 28 February, 2004 by NASA shows a rock called "Humphrey" , taken by the navigational camera on the Mars Exploration Rover Spirit on Mars. The rock's name was inspired by Humphries Peak - the tallest peak in Arizona and part of the San Francisco volcanic complex. Standing approximately .6 meters (about 2 feet) tall, "Humphrey" is one of the largest blocks of what scientists believe is ejected material from one of the rover's long-term targets, the crater dubbed "Bonneville." Likely a basaltic rock, the fractures in "Humphrey" are thought to have been caused by the impact as it was hurled from the crater to its current resting place.
