OperationsThe Huygens Mission Operations Report was prepared by the Flight Control Team and was released in March. The analysis shows that the probe was in good health during the mission and all main events occurred as, and when, expected.

Mission StatusThe spacecraft status is nominal, with the High Gain Antenna (HGA) Z-axis in a fixed position. On 22 March a nominal manoeuvre (station keeping, momentum management and roll) was performed and 0.1003 kg of fuel was used. The remaining hydrazine is 118 kg. The solar array degradation after 112 months of flight is 17.5%, which...

ISO featured prominently in the third (and final) demonstration of the Astrophysical Virtual Observatory project, which was successfully held at ESAC on 25-26 January 2005. The stellar science case "The transition from AGB stars to Planetary Nebulae" made extensive use of ISO data, accessible via VO-compliant tools in creative...

Mission StatusThe spacecraft and its scientific payload are in good health, and no anomalies have occurred during the reporting period. The situation concerning the budget for NASA's contribution to the mission remains a concern.

Mission StatusFrom the operational point of view, the Hubble spacecraft is operating nominally, with the exception of the Space Telescope Imaging Spectrograph (STIS), one of the five on-board science instruments, which failed on August 3rd, 2004.

Overall StatusSMART-1 is approaching the conclusion of its commissioning activities. Sometime in the next few weeks the spacecraft will be handed over to the science teams for full operational activities.

Report for period 8 to 22 April 2005The main activity in the reporting period was the successful first in-flight test of the Near Sun Hibernation Mode (NSHM), during which the spacecraft spent five days in this special low activity mode, with attitude controlled via Star Tracker and thrusters only (gyroscopes and reaction wheels are inactive).
Published: 25 April 2005
Overall StatusThe issue reported in the previous status report (No. 36) concerning EDAC has been ongoing with another error occurring on 4 April 2005. Following discussions between ground control and industry a new procedure was developed, tested and executed on 7 April 2005. As a result a decision was made to only upload Flight Dynamic profiles...

Report for the period 25 March to 7 April 2005The reporting period covers the last instrument observation in Rosetta's Earth swing-by 1 mission phase, the first Payload Passive Checkout and preparation of the Near Sun Hibernation Mode (NSHM) in-flight test.
Published: 8 April 2005
Report for the period 11 to 25 March 2005The reporting period covers the last few post-Earth swing-by spacecraft configuration activities and some delta-commissioning operations on the payload as agreed in the CommissioningReview of December 2004.
Published: 31 March 2005
Overall StatusThe spacecraft is in good health with all functions working nominally. The only noticeable event was an anomaly with the mass memory caused by a double EDAC (Error Detection and Correction). The spacecraft software responded accordingly and invalidated those errors in memory. Ground operations are investigating the cause of the...

Report for the period 25 February to 11 March 2005The reporting period covers the critical activities around the first Earth swing-by of the Rosettamission. All activities were successfully carried out, including operations of the spacecraft andpayload in proximity of the Earth and the first in-flight test of the Asteroid Flyby Mode using...

On 27 February, as planned, SMART-1 entered its final lunar orbit [full details below]. During the transfer trajectory the payload instruments had undergone a commissioning phase to enable observations of the Moon to take place. In order to maximise the results from lunar orbit it is, however, necessary to recalibrate the instruments. This...

During the largest geomagnetic storm of 2004, the redundant attitude computer failed on TC-1 spacecraft. Now both spacecraft have non functioning attitude computers. The consequences are no attitude control of the spacecraft. Fortunately, both spacecraft are spinning at 15 rpm and are therefore stable. A slow drift of the spin axis is observed...

With the successful completion of spacecraft and payload commissioning, the management of the Rosetta mission was transferred from the Scientific Projects Department to the Research and Scientific Support Department.

Mission StatusThe last quarter of 2004 was largely a very productive period of science data taking, except for a 1-week period around early-December, during which an anomaly with the Solid State Mass Memory (SSMM) prevented nominal operations, and some antenna problems towards end-December. The SSMM anomaly, which occurred twice in a row, is...

INTEGRAL operations continue smoothly with the spacecraft, instruments and ground segment performing well. A total of 108 proposals were received in response to the third Announcement of Opportunity for observing proposals (AO-3). The AO covers 18 months of observations from February 2005 onward and the over-subscription in requested time is...
Published: 10 March 2005
Mission StatusThe spacecraft and instruments are operating nominally. An anomaly on one of the CIS (ion) detectors has been observed on spacecraft-2. The problem seems to be on the MCP high voltage. Further investigation is on-going. Ion measurements are being performed on this spacecraft by the second CIS detector. An on-board computer...

Mission StatusXMM-Newton operations continue to run smoothly. The XMM-Newton ground stations were used in support of the launch of Helios and the orbit insertion manoeuvres of Smart-1 at the Moon. This caused the loss of some 40 hours of science time. The upgrade of the overall ground segment from SCOS-1b to SCOS-2000 is continuing. Recently...

Mission StatusThe spacecraft status is nominal, with the High Gain Antenna (HGA) Z-axis in a fixed position. On 8 December 2004 the spacecraft transitioned into Emergency Sun Re-acquisition mode (ESR-24). The reason was a false trigger of the Coarse Sun Pointing Attitude Anomaly Detector (CSPAAD), most likely caused by a particle crossing the...
