Mars Pathfinder Mission Status
January 3, 1997
Mission planners report that NASA's Mars Pathfinder remains
in good health as they plan an adjustment of the spacecraft's
flight path to be executed January 9.
The trajectory correction maneuver, originally scheduled to
take place tonight, is one of four such flight path adjustments
that will take place over the course of Pathfinder's journey to
Mars. The maneuver was delayed to allow time for reprogramming
of some of Pathfinder's attitude control software. Tests showed
that the spacecraft would have obtained erroneous attitude
estimates during the maneuver in response to readings from
Pathfinder's Sun sensors.
Today, Pathfinder is about 8.2 million kilometers (about 5.1
million miles) from Earth and about 162 million kilometers (about
101 million miles) from Mars and traveling at about 32.4
kilometers per second (about 72,646 miles per hour). It will
land on Mars on July 4.
