A word from ESA's Director General
At a post-launch conference held between Kourou, Paris and ESOCDarmstadt, the Director General Of ESA Antonio Rodota said:"The launch of XMM represents a success for Europe. We are veryproud of our satellite, and of the Ariane-5 launcher. The flight hasfurther demonstrated the potential of the new vehicle and we expectmore successes of this kind.So you understand we really are proud tohave been on this first Ariane-5 commercial launch".

SOHO set for a return to normal operations
SOHO is performing maneuvres in preparation for a return toNormal Mode this evening. All instruments are in a safeconfiguration for the maneuvres.Yesterday, a momentum management was performed prior to aroll back to the nominal pointing position. The spacecraft was left inRoll Maneuvre Wheels mode for the night.

Mars Express to learn lessons from Polar Lander loss
"Our hearts go out to our colleagues at NASA's Jet Propulsion Laboratory over the probable loss of Mars Polar Lander," Rudi Schmidt, Mars Express project manager said today. "But risk will always be part of any space mission. We at Mars Express will forge ahead, taking on board all the lessons that we can from the polar lander failure."

Mars Express leaps approval hurdle
The technical design for Mars Express took an important step towards approval last month. A team of 15 space engineers from ESTEC, who are not involved in the project, gave the design the thumbs up after spending a week scrutinising it at the prime contractor's, Matra Marconi Space (MMS), Toulouse. "The team went to Matra to turn the design upside down and find weak points. They didn't find any show stoppers," says Rudi Schmidt, Mars Express Project Manager.

SOHO in CRP mode until 8 December
SOHO is in Coarse Roll Pointing (CRP) mode at a roll angle of -76degrees. The current plan is to leave the spacecraft in thatconfiguration until Wednesday 8 December. Some instruments (MDI, EIT,LASCO and SWAN) are performing observations with some precautionary procedures (so-called 'safing flags') in place.

Eta Carinae - ISO tells the true story
In 1843 the stellar system Eta Carinae suffered a violent explosion which caused it to become, in just a few decades, an amazingly beautiful nebula with two huge round blobs of material symmetrically distributed. For years astronomers have been looking for the cause of the explosion, and to explain the strange hourglass shape. A team of astronomers using ESA's infrared space telescope, ISO, have now succeeded, putting the blame firmly on a previously undetected very massive 'donut' of dust which squeezes the nebula at its centre. They publish their discovery in the current issue of the journal Nature (2 December).

Europe prepares its own Mars mission, as NASA's probe lands on Mars
Just before NASA's Mars Polar Lander bounces to a gentle halt on Mars tomorrow, it will jettison two small probes that will crash into the planet and penetrate its surface. Four years later, in December 2003, another probe will land on the red planet to take a look underground. Called Beagle 2, it will hitch a ride to Mars on Europe's Mars Express mission. NASA's probes will be looking mainly for water and ice, but Beagle 2 will also be searching for the signs of life.

SOHO recovery actions continue
On Tuesday 1 December at 18:46 UT another SOHO spacecraftemergency was declared in order to secure Deep Space Network (DSN) contact with 34-metre antennas, after amanual triggering of the Emergency Sun Reacquisition (ESR) mode at about 18:40 UT.At about 18:10 UT, SOHO was in the middle of astationkeeping (orbit trim) manoeuvreRoll Pointing (CRP) mode was invoked automatically and the thruster burns were aborted. The cause of this anomaly is yet to be determined.

SOHO ESR ends
As of Monday 29 November, 18:35 UT, SOHO is no longer in Emergency SunReacquisition (ESR) mode. The SOHO spacecraft emergency that was declaredto ensure adequate Deep Space Network (DSN) coverage has officiallyended. Instruments are in safe configuration and appear to beunscathed from the episode.

SOHO recovery continues
Recovery of the SOHO spacecraft to normal science operations is proceeding with maneuvres to compensate for stay of about 21 hours in ESR mode, which perturbed the angularmomentum, orbit and roll of the spacecraft.

SOHO in safe mode
Over the Thanksgiving weekend the joint ESA/NASA SOHO recovery team stepped into action once again when the SOHO spacecraft switched to Emergency Sun Reacquisition mode(ESR) on Sunday 28 November. ESR is the safe mode that is automatically triggered to protect the spacecraft in the event of any unforeseen circumstance.
