Mission
Following launch using a Titan/Centaur launch vehicle on August 20, 1975 and a 10-month cruise to Mars, the orbiter began returning global images of Mars about 5 days before orbit insertion. The Viking 1 Orbiter was inserted into Mars orbit on June 19, 1976 and trimmed to a 1513 x 33,000 km, 24.66 h site certification orbit on June 21. Landing on Mars was planned for July 4, 1976, the United States Bicentennial, but imaging of the primary landing site showed it was too rough for a safe landing. The landing was delayed until a safer site was found. The lander separated from the orbiter on July 20 08:51 UTC and landed at 11:53:06 UTC. It was the first attempt by the United States at landing on Mars.

Famous quotes containing the word mission:

—Umberto Eco (b. 1932)
“I cannot be a materialist—but Oh, how is it possible that a God who speaks to all hearts can let Belgravia go laughing to a vicious luxury, and Whitechapel cursing to a filthy debauchery—such suffering, such dreadful suffering—and shall the short years of Christ’s mission atone for it all?”
—D.H. (David Herbert)
“The mission of men there seems to be, like so many busy demons, to drive the forest all out of the country, from every solitary beaver swamp and mountain-side, as soon as possible.”
