No. 120 - Payload check-out 10

Report for Period 26 September to 2 October 2009The reporting period covers the second week of the payload check-out 10 (PC10). Instruments were activated, tested, and calibrated and software updated as planned. Both the spacecraft and the ground segment are behaving nominally.

Mission operations have been conducted with support of the ESA New Norcia (NNO) ground station.

PC10 - Philae lander and COSIMA

At the end of the reporting period (DoY 275) Rosetta was at 37.94 million km from Earth (0.25 AU) and the one-way signal travel time was 127 seconds. The distance to the Sun was 183.97 million km (1.23 AU).

Spacecraft

Payload
Many of the instruments were activated as part of the ongoing payload check-out activities. The Standard Radiation Environment Monitor (SREM) continues to run in the background.

ALICE
The instrument is currently OFF. The planned PC10 activities were completed.

CONSERT
The instrument is currently ON for a last test planned shortly after the end of the reporting period. Several interference and ping-pong tests were conducted during the reporting period. Tests are focused on achieving a good understanding of the mutual behaviour of the orbiter and lander part of the instrument.

COSIMA
The instrument is currently OFF. All the PC10 activities planned in the reporting period were nominal.

GIADA
The instrument is currently OFF.

MIDAS
The instrument is OFF. All the PC10 activities planned in the reporting period were nominal.

MIRO
The instrument is currently OFF. A software patch was performed on DoY 270 and the preliminary analysis indicates a successful result.

OSIRIS
The instrument is OFF.

ROSINA
The instrument is OFF. All planned PC10 activities have been successfully conducted on DoY 271. The instrument behaviour is nominal.

RPC
The instrument is OFF. All planned PC10 activities were successfully concluded.

RSI
The instrument is muted. The PC10 activities will be conducted during next reporting period.

VIRTIS
The instrument is currently OFF.

LANDER Philae
The lander will remain ON for the next days in support of the CONSERT tests. After the successful patches and low level tests carried out last week, this week was dedicated to more in depth tests and combined operations between the instruments. A few replanning exercises also took place (PTOLEMY, CIVA-P).

SREM
Since DoY 251/2009 the accumulation settings are configured for active cruise mode.

Future Milestones

The payload check-out number 10 will be completed within the next week. After this densely packed operational phase, focus will shift to the navigation campaign for the mission's third and last Earth swing-by to take place on 13 November 2009. In the month preceding the Earth swing-by a re-lubrication of reaction wheel B will be performed.
