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.

Integral and Rosetta on show in Turin
In Turin today the Italian satellite builder Alenia Aerospazio presented two ESA spacecraft that will explore the near and far Universe: Integral, the gamma-ray observatory, will gather the most energetic radiation coming from distant objects. Rosetta, the comet chaser, will bring new insights in the formation of our solar system.

Living the Leonids
"From here the peak was around 2200 meteors at 02:13", reported an excited Michael Schmidhuber, ESA's man aboard the international plane at 03:08 UT, calling in from somewhere over Greece to the waiting scientists gathered at ESTEC. First pictures from the two ESA science teams in Spain began to arrive at 02:39 UT. At 02:00 UT Jo Zender reported from Calar Alto: "We are now seeing more than 250 meteors per hour, more than one every half minute."

The Leonids are back: is a storm brewing?
For updates throughout the night see Leonids 99 including new video interviews and the sound of the meteors. You can also put your questions direct to ESA's experts in a live chat forum this evening!Will the night sky be illuminated with thousands of shooting stars - known to scientists as the Leonid meteors - on the night of 17/18 November? No-one knows for sure, but some experts are predicting a dramatic display over Western Europe which will rival any millennium celebrations.

INFO 16-1999: Cluster II quartet take the stage together
Visitors to the test and integration facilities at IABG near Munich, Germany, on 24 November may be excused for thinking they are suffering from multiple vision. On display there, in a giant clean room, will be not one but four identical cylindrical spacecraft. This is the only occasion on which all four of ESA's Cluster II spacecraft will be on display together in Europe.

Europe is going to the Moon
A highly innovative and budget-priced mission to explore the moon has formally been approved by the European Space Agency. Meeting in Paris 9 and 10 November the Agency's Science Programme Committee has finalised all aspects of the SMART-1 project. This small lunar orbiter is the first in a new line of Small Missions for Advanced Research in Technology to demonstrate new key technologies for future deep space missions.

SOHO prepares to weather the Leonid's meteor storm
The Earth will have another close encounter with Comet Tempel-Tuttle's dust trail in the early hours of 18 November, and the resulting meteor storm, called the Leonids, could be spectacular.But the storm so eagerly awaited by astronomers is also making spacecraft controllers take precautions. Like a ship caught in a tempest, ESA's Solar and Heliospheric Observatory (SOHO) will try to stay as safe as possible during the meteor storm.

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).
