First U.S. Spacecraft on Mars

Posted on Mon, November 28 2016

Viking 1 and 2 were the first U.S. spacecraft to successfully land on Mars. The two landers were equipped to complete Viking’s core mission: search for life on Mars. The landers were essentially laboratories, and could run tests on site. Though no evidence of Martian life was found, the wealth of planetary data and photographs the Viking spacecraft sent to back Earth made a great impact on planetary science.
