XMM in safe hands
During the first hours after XMM's acquisition by the Perth groundstation, the spacecraft control teams at ESOC nursed their babythrough its initial in-orbit sequences. Triggered by the onboardtimer, the two wings of the solar array opened faultlessly, thetelescope sunshield equally well. The star trackers were switched onand the spacecraft's reaction wheels were spun up.

XMM takes pictures of itself!
The XMM spacecraft, launched on 10 December from Kourou, has sent back pictures of itself in space.The photographs were taken by two micro-cameras placed on the exterior of the spacecraft's focal plane assembly. Provided by Optronic Instruments and Products (OIP) - Delft Sensor Systems, and IMEC, Belgium, the two cameras (10 x 6 x 6cm) each weigh but 430 grams.

PR 53-1999: Europe's latest space telescope is off to a good start
The world's most powerful observatory for X-ray astronomy, the European Space Agency's XMM satellite, set off into space from Kourou, French Guiana, at 14:32 UTC on 10 December. The mighty Ariane 5 launcher, making its very first commercial launch, hurled the 3.9-tonne spacecraft into a far-ranging orbit. Within one hour of lift-off the European Space Operations Centre at Darmstadt, Germany, confirmed XMM was under control with electrical power available from the solar arrays.

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".

INFO 19-1999: Lifting the veil on the X-ray universe
X-ray astronomy is a relatively young branch of astrophysics which today is one of the most competitive and popular. In the few decades since the discovery of X-ray radiation from cosmic X-ray sources, this field has grown at an astonishing rate leading to the identification of numerous exciting new phenomena.

XMM System Verification Test 3
Thursday 14th October, day four of SVT-3. The object of the third and final XMM Systems Verification Test before launch is to command the spacecraft at a distance, as if it were in orbit, and particularly to control the reception of information from its science payload. It is the first time that the six cameras and radiation monitor installed on the spacecraft provide their data to the XMM Science Operations Centre (SOC).

PR 43-1999: Reaching out to youth. And the winners are.....
In recent weeks ESA has been actively promoting a series of activities addressing the younger generation, in a concerted effort to stimulate their interest in space and involve as many young Europeans as possible in the Agency's activities. To celebrate the launch of ESA's XMM X-ray telescope in December, for instance, two competitions for European schools were announced in September: "Draw me a Telescope" and "What's new, Mr Galileo ?"

X-ray study of the 'Winking Demon' reveals its flaring secrets
An X-ray observation of the 'Winking Demon', one of the sky's nearest and X-ray brightest stars, has revealed that its huge X-ray explosions take place in structures similar in relative size to those of our own Sun - contrary to what had been previously suggested. The study by J|rgen Schmitt at Hamburg University and Fabio Favata at the ESA-ESTEC Space Science Department has just been published by the magazine 'Nature' (dated 1 September 1999) and in 'Astronomy and Astrophysics' (currently in press).
