The fate of the Universe depends on the total amount of existing matter.New clues on this value have been obtained by an international team ofastronomers using the European Infrared Space Observatory, ISO, bymeasuring for the first time the abundance of a particular chemicalelement, deuterium, in a very active star-forming region in the Orionnebula. Their result confirms that the total amount of normal matter isnot enough to stop the expansion of the Universe and cause it to collapseinto a Big Crunch in the future.

The XMM Upper Module, bearing the Focal Plane Assembly, is currently being tested in the Large Space Simulator (LSS) at ESTEC. Before closing the chamber and starting the pump-down for theThermal-Balance/Thermal Vacuum (TB/TV) tests, some final checks were made on the facility motion system. The TB/TV tests are scheduled to lastten days.

Researchers who feel they have an astronomical scoop based on data from the European infrared space telescope, ISO, must now work against the clock. They risk being overtaken by other groups, especially now that the ISO Data Archive, a goldmine of discoveries filled with nearly 30 000 scientific  ISO observations, is open and easily...

If you want an asteroid named after you, make a valuable scientific contribution to the study of these rocky mini-planets of the Solar System. That is what 32 year old ESA astronomer Thomas Müller did, and now the International Astronomical Union has rewarded him by giving the name 'Thomasmüller' to asteroid number 8793.

On Saturday 13 February 1999, the Space Science Department (SSD) of ESA hosted the "Meteorendag 1999", the annual meeting of the 'Werkgroep Meteoren'. About 40 people participated in this highly successful meeting, which concentrated on reports from the Leonid observations last year. Members of the Werkgroep, the Dutch Meteor Society, and the German ArbeitskreisMeteore presented results from their expeditions to South Korea, China, and Mongolia.

XMM passed an important milestone on 9 February, with the arrival at ESTEC of the upper half of the spacecraft, from Dornier, Friedrichshafen, Germany. The journey from southern Germany to the Netherlands, with the Black Forest pass deep in snow, was quite an adventure in itself for the two extra-wide trucks carrying the upper module and the delicate high-tech imaging camera built by European scientists.

Like water gushing through cracks in a dam, scientists observed "fountains" of electrified gas, called the solar wind, flowing around magnetic regions on the Sun to begin their 3-million-kilometre-per-hour rush into space. Scientists have identified regions on the Sun where the high speed solar wind - a stream of electrified gas affecting Earth's space environment - originates.

On 2 February, the Astrophysics Division's S-CAM instrument saw 'firstlight' at the 4.2m William Herschel Telescope on La Palma, observing thepulsar at the centre of the Crab nebula.S-CAM, a totally new instrument concept, is equipped with an array of'superconducting tunnel junctions' (STJ), small chips of the metaltantalum, cooled with the help of a bath of liquid helium to a temperaturewithin a degree of absolute zero.The Crab Pulsar provides an ideal target for verifying the camera's photoncounting and timingcapabilities. The figure shows the characteristic 'light curve' signatureof the pulsar: two beams of light which shine out, like a lighthouse, oneweak and long the other bright and short, in each revolution. These datawere obtained from just one of the 36 tantalum chips in S-CAM in a fourminute exposure.

New photographs and details of the dual launches involving the four Cluster spacecraft have now been posted on the Cluster web site. The new pages include information on launch preparations, the launch site, the spacecraft orbits and the Soyuz launcher with its newly developed Fregat upper stage which will boost the Cluster spacecraft into their preliminary parking orbit.

For the second time in six months, engineers have revitalised ESA's orbiting solar observatory SOHO, and have also set a space record.The spacecraft went into a self-protection mode (called Emergency Sun Reacquisition - or ESR) on 21 December, when the last of its three gyroscopes failed. Having lost a fundamental orientation system, SOHO continually fired onboard jets to keep its sensors pointed toward the sun.

As part of a four-day American tour on current European/US cooperative projects, Prof. R.M. Bonnet, ESA's Director of Science, today visited NASA Goddard Spaceflight Center (GSFC). During the visit he met with the SOHO management and operations teams, both to review forthcoming operations on SOHO and, more importantly, to offer his personal congratulations for the extraordinary efforts they put into the recovery of SOHO in the period June to October last year.
