SOHO Recovery Updates |
The DHSS problem found the day before yesterday was not a hardware issue, but due to the uplink of Mode 3 commands a little bit too fast. Once the timing of this commands was sligthly changed, the script to transition the spacecraft from ESR mode to RMW (through ISA and FSA modes) was run again yesterday morning without a glitch. The spacecraft is in RMW mode, using a 4.7 magnitude star, since 16:58 UT, yesterday. While on FSA, both SSUs were successfully checked out.
Other activities accomplished were the uplinking of ACU patches 5 and 6, and the warm start up recovery using the nominal recovery procedure, so DHSS is now back in the nominal branch.
