No. 133 - Start of payload check-out 12
28 April 2010 11:40
Report for Period 17 April to 23 April 2010
The reporting period covers one week of Rosetta mission operations and saw the start of the spacecraft check-out 11 and the active payload check-out 12 (PC12).
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 113) Rosetta was at 222 million km from Earth (1.48 AU) and the one-way signal travel time was 740 seconds. The distance to the Sun was 312.6 million km (2.09 AU).
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 the next three weeks, during which most of the 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.
