No. 94 - Cruise Phase
19 February 2008 12:00Report for Period 19 January to 15 February 2008
Rosetta is continuing its 4th orbit around the Sun as part of its interplanetary journey. The spacecraft distance from the Sun will now increase to reach a maximum of ca. 2.26 AU in December 2008.
Activities had a relatively low profile during the reporting period and performance of the mission has been nominal. Support was provided by NASA DSN stations when ESA New Norcia station was down for maintenance.
At the end of the reporting period (DoY 046) Rosetta was at 56.53 million km from Earth (0.37 AU) and the one-way signal travel time was 188 seconds. The distance to the Sun was 168.97 million km (1.129 AU).
SpacecraftDuring the reporting period a major OBSM activity was conducted on the OSIRIS instrument
The cruise phase continues towards asteroid Steins that will be encountered early September 2008. During the next weeks Rosetta will complete the Steins observation campaign and start the reconfiguration of the various spacecraft subsystems for intermediate Sun distances. The reconfiguration will be completed in March before the entry in Near Sun Hibernation Mode. The second leg of the post-Earth Swing-by trajectory correction is planned for 21 February 2008.
