Comet provides a wealth of new X-ray data
Most of their time is spent frozen in the outer reaches of the solar system. But when these balls of ice and dust, which we know as comets, decide to make an appearance, the spectacle is often grandiose. This is mainly caused by their warming up as they approach the Sun. Astronomers then have a chance to investigate comets closely, including at X-ray wavelengths, as XMM-Newton did at the end of January 2001.

ESA's solar system missions to get star billing in Nice
Geophysicists attending next week's General Assembly of the European Geophysical Society in Nice won't just be discussing the latest scientific research about the Earth. They will also be turning their attention to other bodies within our solar system and the missions Europe is sending to explore them.

Prime Contractor selected for ESA's Herschel and Planck space satellites
On 14 March, in Paris, ESA's Industrial Policy Committee approved the awarding of the main contract for the manufacture of the Herschel and Planck scientificsatellites. This contract, the largest so far for a space science project undertaken by ESA, has been awarded to a European industrial consortium led by Alcatel Space Industries of France, with Astrium GmbH of Germany and Alenia Spazio of Italy also as main contractors.

SMART-1 structural model takes shape
Last week marked the start of the integration campaign for ESA's SMART-1 mission. On 13 March, SMART-1 began to take shape as assembly of the structural model (STM) began at the APCO integration facility in Vevey, Switzerland.

Chilly test for INTEGRAL's spectrometer
The centre of attention was not a fashion model. But, as in a haute-couture fashion house, it was being dressed for the big day. Nimble fingers cut and trimmed, and dazzling gold-coloured material was delicately pinned and attached.

A night to remember: the Giotto flyby of Halley's comet
Exactly 15 years after the intrepid Giotto spacecraft swept past the nucleus of Halley's Comet, ESA scientist Gerhard Schwehm shared his memories of past triumphs while looking forward to new revelations from the Rosetta mission.

Mars Express completes its first journey - from Zurich to Stevenage
If youre travelling on Europe's roads this year, you may spot a very large vehicle (5m long and 3.5m wide), bearing the Mars Express logo. It will be making slow progress and will be accompanied by a police escort. Inside the clean, air-conditioned environment will be the Mars Express spacecraft in transit between industrial contractors in Switzerland, the UK, Italy or France.

Call for ideas for the re-use of the MARS EXPRESS platform
To be launched in 2005Note that the briefing for the Call for Ideas for the re-use of the Mars Express platform will take place on 23 March 2001, in Paris Headquarters, room Cinema, from 13h00 to 15h00.The search for more efficiency is a constant concern of the Science Directorate since the initiation of the Horizon 2000 programme. As shown to ESA's SSAC and SPC, a number of scientific missions have led to considerable savings achieved by adopting newmanagement procedures, exploiting cheaper industrial costs (especially the re-using platforms or subsystems developed for the other missions), and accessing cheaper launchers.

Bush fire scare at Perth ground station
Whilst XMM-Newton delves into the hottest places in the Universe, life down on planet Earth can sometimes also be too warm for comfort. Pictures have become available of a bush fire that recently threatened the X-ray observatory's tracking station near Perth. Science operations were unaffected.

Hubble spies huge clusters of stars formed by ancient encounter [heic0103]
Beautiful, detailed Hubble images of the centre of the prototypical starburst galaxy M82 point to a violent past. An ancient burst of star formation that gave birth to more than 100 super star clusters is linked to a violent encounter with the galaxy's large neighbour, M81.

"First Convention of LUNAR explorers" - Invitation to the media
Will the Moon be the ultimate travel destination? Can we harness energy from the Moon? How and when can we build a lunar base or a lunar village? Will it be possible to transform that barren landscape 384 000 kmaway into a thriving hub of scientific research and industrialization? These and other questions will be discussed during the first Convention of Lunar Explorers (LUNEX) in Paris, at the Palais de la Dicouvertefrom 8 to 10 March.

New findings on amino-acids in meteorites show the potential of Rosetta for astrobiology
An object that fell to Earth more than 136 years ago has revealed new clues about the origin of meteorites in space and new information about how life may have risen on the early Earth. The new study by astrobiologist Pascale Ehrenfreund and collaborators shows that the Orgueil meteorite, which fell in France in 1864, may be the first meteorite traced to a comet, rather than to an asteroid, the source widely believed to produce meteorites. The contents within Orgueil, the study says, may have been just the type of fundamental ingredients necessary to help generate life on Earth. Scientists have generally believed that a wide variety of amino acids were required for the origin of life on Earth. "Recent research suggests, however, that only a few types of simple amino acids may have been required, and that is exactly what was found to be present in Orgueil" .

Astronomers scramble to use INTEGRAL
The Call for Proposals to use guest observer time on ESA's forthcoming gamma-ray observatory has resulted in 291 individual proposals. These represent approximately 323 million seconds - more than 10 years - of observing time! This is 19 times greater than all the open time available during the first half of the nominal two-year mission.

"Stop monster! Show us your spectrum!"
One must admit that spectra, the many-varied curves that plot the number of photons and their energy, appear to be rather uninspiring to the layman; nothing worse than a graph. But like one's body temperature curve, they mean a lot.

Hubble Zooms In on Bar of Favourite Spring Spiral Galaxy [heic0102]
Astronomers have long suspected that the bar systems that dominate the appearance of some spiral galaxies provide an efficient mechanism for fuelling star births at their centres. New results from the NASA/ESA Hubble Space Telescope provide evidence that this is indeed the case.

SOHO analyses a kamikaze comet
A comet that fell into the Sun on 7 February was tracked by twodifferent instruments on the ESA-NASA SOHO spacecraft, enablingscientists to characterize it quite precisely. This was just one ofnearly 300 comets discovered by SOHO since 1996, thanks mainly to theprivileged view of the sky around the Sun given by the visible-lightcoronagraph LASCO. On this occasion SOHO's ultraviolet coronagraph UVCSalso observed the comet repeatedly. It gave valuable additionalinformation, both about the comet and about the solar wind close to theSun.
