An update just in tonight from Spacecraft Operations Manager Andrea Accomazzo in the Rosetta Dedicated Control Room at ESOC.

The 'GO' telecommand, which starts the ball rolling on board Rosetta for final automated sequence for hibernation entry, was sent yesterday evening at 21:47 UTC (23:47 CEST). The team at ESOC saw it execute on board the spacecraft about one hour later, at 00:47 CEST, which confirms satellite is on track for hibernation later today.

Basically, the entire sequence to command entering into hibernation is loaded on board and will start automatically, stopping only to wait for the final (manual) command to complete shut-down, due after 13:00 CEST.

Next big event? The spin up manoeuvre at 10:00 CEST today. -- Daniel
