FOR RELEASE: THURSDAY, OCTOBER 14, 1971
The Mariner 9 spacecraft, in its 137th day of travel to
Mars, has covered 209,860,000 million miles since launch on May
30 from Cape Kennedy.
The arrival date at Mars for the 2200 pound spacecraft
is November 13, when a 15 minute burn of its 300-pound thrust
rocket engine will place Mariner 9 into a twice-daily Mars orbit.
Relative to Earth, the spacecraft is currently
traveling at 34,897 mph and is 51,016,000 miles from Earth as it
slowly closes towards the orbital path of Mars.
The basic objective of the mission is 90 days in Mars
orbit and mapping about 70% of the Martian surface with two
television cameras. Other experiments will record atmospheric
and surface data.
