- MARS OBSERVER MISSION STATUS
- January 25, 1993
-
- The Mars Observer spacecraft team reports that all
- spacecraft and science operations are performing well.
-
- The Mars Observer camera, magnetometer/electron
- reflectometer and gamma ray spectrometer were turned on Jan. 18
- for instrument calibration activities, and began returning data
- the following day. The camera focus tests were completed at noon
- today, while data-gathering by the two other instruments
- continues this week.
-
- Data from the magnetometer recorded near the Earth's geotail
- -- that region of space in which the solar wind is blocked as the
- Earth orbits the sun -- will be played back from tape recorders 1
- and 3 on Jan. 26 and 27. Meanwhile, a telecommunications
- experiment, called the "Ka Band Link Experiment," is being
- performed to test the quality of ground-to-spacecraft
- communications using a very short, 9-millimeter (36/100ths of an
- inch) wavelength and a low-power transmitter on board the
- spacecraft. All other uplink and downlink activities are now
- performed using the spacecraft's high-gain antenna.
-
- Today the spacecraft is about 64 million kilometers (40
- million miles) from Earth, traveling at a speed of about 47,000
- kilometers per hour (31,000 miles per hour) with respect to
- Earth. The spacecraft is traveling at a heliocentric velocity of
- about 93,500 kilometers per hour (58,000 miles per hour). One-
- way light time is roughly 195 seconds.
