- A few days ago, I mentioned the plans had for trying to unstick the high gain
- antenna on Galileo (this in the context of a discussion of Uri Geller).
- Someone was skeptical of my description, and was under the impression that what
- I was describing had been cancelled, replaced by something else.
- Unfortunately, I don't remember who that person was. So I post to the group
- an excerpt from a bulletin issued by the Galileo Project manager today:
-
- =Forwarded from Bill O'Neil, Galileo Project Manager
-
- = GALILEO STATUS REPORT
- = December 28, 1992
-
- = Today, December 28, 1992, the HGA (High Gain Antenna) warming to a 45
- =degree off Sun angle is scheduled in preparation for the DDA-5 (Dual Drive
- =Actuator #5) windup hammering activities. Real-time commands are scheduled
- =to update the system fault protection response and to modify attitude control
- =fault protection precision level in support of the motor acuation activity.
- =Tracking is scheduled over DSS-43 and DSS-63.
-
- = Tomorrow, after approxiamately 28 hours at warming attitude, real-time
- =motor windup hammering commands are scheduled to be sent beginning at approx
- =6:56 AM PST for a period of up to 20 hours. Tracking is scheduled over DSS-14,
- =DSS-43 and DSS-63.
-
- Translating that from NASA-speak, they're planing to turn the motor that's
- supposed to deploy the antenna on and off repeatedly, hoping that it will
- eventually manage to free the stuck pins.
-
- I wonder whether Uri will actually claim credit if this succeeds?
