SOHO recovery continues
01 Dec 1999Recovery of the SOHO spacecraft to normal science operations is proceeding with maneuvres to compensate for stay of about 21 hours in ESR mode, which perturbed the angular momentum, orbit and roll of the spacecraft.
Yesterday, 30 November, SOHO was returned to its nominal roll position and pointing, and the solid state recorder (SSR) was turned on overnight before the scheduled gap in Deep Space Network (DSN) contact.
Planned recovery activities for today are several momentum management and station keeping segments (orbit trims) to return SOHO to its nominal configuration. Fuel consumption for today is estimated to be around 800 grams.
The spacecraft will be returned to Normal Mode at the end of the day, and instrument recovery operations are scheduled for 2 and 3 December.
