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.

The Japanese/US X-ray astronomy mission ASCA was launched in 1993.Its advanced detectors continue to provide high resolution spectra ofmany classes of astronomical objects.The long list of ASCA discoveriesinclude the detection of broad, heavily distorted, iron linesfrom some Active Galactic Nuclei. These red-shifted lines providedirect evidence for the presence of massive black holes at thecenters of these galaxies.

The third inflight checkout of the Huygens Probe was successfully completed over the Christmas period. All systems and experiments performed as expected. Huygens can now sleep on for the next 8.5 months, until its next wake up call in mid-September 1999. Checking of the Cassini's spacecraft continues throughout the month of January.
