After successfully landing on Mars, NASA rover Curiosity had its first test drive last week, sending back footage which some believed showed aliens. Curiosity moved forward just 15 feet, rotated 120 degrees and reversed 8 feet during its 16 minute test drive.
The footage sent back by Curiosity contained some blurry images and unidentified moving objects which some observers speculated might be aliens. Some experts explained later that the dust cloud was in fact generated when Curiosity landed, and the unidentified objects were probably dirt on the camera.
