Report for Period 1 May to 7 May 2010The reporting period covers the third week of the active payload check-out 12 (PC12) for Rosetta. All the planned PC12 activities were successfully conducted according to plan.

During the reporting period, mission operations have been conducted with support of the ESA New Norcia (NNO) ground station.

At the end of the reporting period (DOY 127) Rosetta was at 272 million km from Earth (1.75 AU) and the one-way signal travel time was 874 seconds. The distance to the Sun was 321.6 million km (2.2 AU).

Spacecraft

Payload

ALICE
The instrument is currently OFF. It was activated several times as part of the PC12 activities, which included a boresight alignment with OSIRIS.

CONSERT
The instrument is currently OFF.

COSIMA
The instrument is currently OFF.

GIADA
The instrument is currently OFF.

MIDAS
The instrument is currently ON for final checks as part of the PC12 activities. The new software version 6.5.2 was successfully tested on DoY 123.

MIRO
The instrument is currently OFF.

OSIRIS
The instrument is currently OFF. It was activated between DOY 119 and DOY 121 for a boresight alignment with ALICE and for obtaining a light curve of asteroid Vesta.

ROSINA
The instrument is currently OFF. It was activated on DOY 125 to apply software version 7.7 to the redundant side.

RPC
The instrument is currently OFF. A passive check-out was successfully run between DOY 121 and DOY 122.

RSI
The ultra-stable oscillator is ON/muted since DOY 032/2010.

VIRTIS
The instrument is currently OFF. It was activated on DOY 121 in parallel to OSIRIS for the light curve measurements of asteroid Vesta.

LANDER Philae
The instrument is currently OFF. It was activated between DOY 123 and DOY 126 as part of the PC12 activities.

SREM
The instrument is ON with standard settings since DOY 032/2010.

Future Milestones

Rosetta continues cruising towards asteroid Lutetia. The Rosetta spacecraft is configured in normal mode, in which it will nominally remain until the deep space hibernation entry in June 2011.

The payload check-out (PC12) activities will continue for one more week, during which several instruments will be activated for a final check/update before the flyby of asteroid Lutetia.

The navigation campaign for the Lutetia flyby will begin at the end of May 2010. The closest approach to the asteroid, on 10 July 2010, is currently expected at 15:44:53 UTC.
