NOTE TO EDITORS:
The Mariner 9 spacecraft at Mars will resume transmis-
sion to Earth of Mars photographs and other science data on
Friday, October 13.
The photographs will be displayed on TV monitors, as
received, in the Von Karman press room at the Jet Propulsion
Laboratory, 4800 Oak Grove Drive, Pasadena, from 12:30 p.m.
thru 4:30 p.m.
This will be one of the last picture playbacks from
Mariner as it is estimated that sufficient attitude control gas
remains for only a few playbacks. The next playback, gas per-
mitting, is scheduled for October 17.
Mariner 9 reached Mars on November 13, 1971, completed
its assigned 90 days at the planet and has continued to operate
well beyond the time alloted.
The spacecraft has mapped the entire planet, returning
7,273 photographs. The photographs revealed an unexpected sur-
face with huge volcanoes, 2 mile deep canyons and what appears
to be ancient streambeds carved by running water.
A 35-foot long mosaic of thousands of pictures showing
the canyons and volcanoes is on exhibit in the press room.
