The Apollo 1 Hills are three hills on Mars named to memorialize the crew of Apollo 1. The three hills were some of the first landmarks sighted following the January 7, 2004, landing of the Spirit rover on Mars.

Background

NASA astronauts Gus Grissom, Roger Chaffee, and Ed White perished in a flash fire which engulfed their command module on January 27, 1967, while training for the first of the crewed Apollo missions, initially designated as Apollo Saturn-204 (AS-204). The craft was set to launch three weeks later, on February 21, 1967.

Location

The three vastly separated hills are located in the Gusev crater, part of the Aeolis quadrangle on Mars.

The hills are named in memory of the three Apollo 1 astronauts.
