Frontier II was the name of the NASA mission that achieved the first-ever human landing on the surface of Mars, launching from the Amarillo Space Center in Amarillo, Texas on June 8th, 2002 and arriving in Mars' orbit on March 15, 2003. After 15 days in orbit, astronauts Owen Wilson, Ted Collins, Samantha Arbiter and Ethan McGrady piloted the landing craft Voyage I down to the surface of Mars, where they spent days collecting samples and attaching the craft to the rocket that would propel them back into Mars' orbit on April 3rd. On December 19th, 2003, the Frontier II returned to Earth's orbit, and the Voyage I reentered the atmosphere with all seven astronauts on the mission aboard and successfully landed in the Indian Ocean.
