No. 74 - Ongoing Preparations for Mars Swing-by
29 January 2007Report for Period 13 January to 26 January 2007
The reporting period covers a period of 2 weeks with minor preparatory activities for the Mars swing-by phase.
During the reporting period the following activities have been conducted:
All activities have been conducted according to the plan without any major problem. The navigation campaign for the Mars swing-by is proceeding according to the plan with radiometric data acquired by ESA (NNO: New Norcia) and DSN stations.
At the end of the reporting period (DOY 026) Rosetta was at 316.3 million km from Earth (2.11 AU; one-way signal travel time was 17 minutes 35 seconds). The distance to the Sun was 198.2 million km (1.32 AU).

The Mars swing-by phase formally started on 28 July 2006. The actual swing-by will take place on 25 February 2007, followed by a Deep Space Manoeuvre in April 2007. Preparation activities for the Mars swing-by will continue in the coming weeks with the following plan:
The navigation campaign will continue its most dense phase with several tracking passes per week and DDOR measurements, both with ESA and DSN stations.
The ground segment has started the formal validation campaign for the Mars swing-by scenario with the first simulation, 4 additional ones are foreseen in the next weeks.
