The spacecraft is now flying its 288th orbit, in good status and with all functions performing nominally. The new thrusting strategy is well in progress with thrust arcs around perigee for about one third of every revolution. Presently the thrust arcs last for about 15 hours of every 42 hour-orbit. The thrust duration will progressively increase...

Overall Mission StatusThe overall operational performance of all spacecraft subsystems is good. Following difficulties encountered with the Solid State Mass Memory (SSMM) in the March-April timeframe, the upload of a new Solid State Mass Memory software version took place successfully in mid-April. No science operations were possible during the...

Report for week 30 April to 7 MayPayload commissioning activities continued in the reporting period. For the first time a scientific activity was executed: the observation of comet Linear. Four remote sensing instruments, MIRO, ALICE, VIRTIS and OSIRIS took measurements and images during this special pointing operation.

Report for week 23 to 30 April 2004Payload commissioning activities continued in the reporting period. For the first time the spacecraft was rotated such that the payload could point towards the Earth. This gave MIRO and VIRTIS the opportunity to take calibration measurements using the Earth as a target.

The spacecraft is now in its 278th orbit, in good status and with all functions performing nominally. The new thrusting strategy is well in progress with thrust arcs around perigee for about one third of every revolution. Presently the thrust arcs last for about 13 hours of every 36 hour-orbit. The thrust duration will increase to 18 hours when...

Report for week 9 to 16 April 2004Payload commissioning activities continued in the reporting period. The main activity was the second commissioning slot of the Lander, mainly dedicated to Lander payload operations. All activities were successfully completed, with the exception of a few procedures that will have to be repeated in Lander slot 3...

The spacecraft is now flying its 264th orbit, in good status and with all functions performing nominally. After the eclipse season, the new thrusting strategy is progressing well with long thrust arcs around perigee occurring every orbit for about 10.5 hours. During the coming month this will be increased to 14 hours per orbit.

The spacecraft has completed over 250 orbits, is in good status and with all functions performing nominally. The eclipse season is now over, with the last eclipse occurring on 21 March. The longest eclipse occurred on 13 March (lasted for 2 hours and 15 minutes) and stressed the power systems to their maximum limit. The spacecraft performed...

SummaryThe spacecraft and ground segment continue to operate well. All activities planned for the initial, critical phase after launch have been successfully completed ahead of schedule. In the early morning of 5 March the Mission Control Team at ESOC has moved from the Main Control Room to the Rosetta Dedicated Control Room to commence the...

Overall Mission StatusThe mapping orbit of Mars Express was reached on 28 January 2004. All manoeuvres leading to that orbit were executed with very high accuracy. The operational performance of the spacecraft and payload is excellent, and all instruments have been successfully checked out. Remaining commissioning activities will be performed...
