- GALILEO MISSION STATUS
- July 22, 1992
-
- The Galileo spacecraft is more than 204 million kilometers
- (about 127 million miles) from Earth, and some 269 million
- kilometers from the Sun; its speed in orbit is 20,651 meters per
- second or 46,194 miles per hour. The spacecraft has flown about
- 2.13 billion kilometers (1.32 billion miles) since launch.
-
- This week Galileo is conducting exploratory activities with
- the high-gain antenna deployment motors and retracting its rear-
- view low-gain antenna. On Monday, the flight team sent the mini-
- sequence for these operations to the spacecraft.
-
- Tuesday, the spacecraft turned to a warming attitude (31
- degrees off the Sun) and turned on the antenna-deploy motors for
- less than 2 seconds, and today, Wednesday, the motors are being
- turned on for another 2 seconds after 24 hours of warming. (The
- first deploy-motor pulse was done April 29, when the antenna
- tower region was somewhat cooler).
-
- Thursday, July 23, the spacecraft's second low-gain antenna,
- which pivots down on a long mast from one of the RTG booms, will
- be driven back up to its stowed position. This action will exert
- small forces on the spacecraft, which will be measured using the
- spacecraft gyros.
-
- Engineering telemetry for these events will be captured on
- the spacecraft tape recorder and played back each day. The
- engineers believe these activities may provide a better under-
- standing of the antenna situation to support future action.
