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.

At 17:49 UTC on 21 December, the SOHO Spacecraft went intoEmergencySun Reacquisition (ESR). Following a successful gyro calibrationmanoeuvre,prior to a planned orbit correction and momentum wheel managementactivities,the last of SOHO's gyros (Gyro B) failed to give the expected output.This occurred during transition from normal mode to momentum dumping mode,and resulted in the spacecraft transitioning into ESR-10.

The fifth large MUSICOS (Multi-site continuous spectroscopy) campaign has just finished, lasting from 20 November to 14 December 1998. It involved 13 telescopes mostly equipped with cross-dispersedechelle spectrographs in Haute Provence, Pic du Midi, La Palma, SouthAfrica, ESO La Silla, Brazil, Kitt Peak, Xinglong, Mt Stromlo, Catania,Caucasus SAO. The campaign was coordinated daily by B.H. Foing and J. Oliveira (Space Science Department of ESA).Although some sites suffered snow and winds, the overall coverage was successful. S. Orlando (SSD) observed from Xinlong observatory near Beijing in Siberian winter, with temperatures of -15 deg.!

After a four-hour road journey from Lihge in Belgium, the three flight model mirror modules, the most powerful X-ray optics in the world, have arrived today at ESTEC, ESA's technical centre in Noordwijk, The Netherlands. It was the last road journey for the 'eyes' of ESA's X-ray space observatory. Early next year, the three mirror modules will be assembled on the spacecraft, ready for launch in January 2000.

The Rosetta comet rendezvous mission has passed another significantmilestone. According to ESA's usual practice for major projects, a Rosetta Mission System Design Review took place at ESTEC in The Netherlands on 10 December 1998. Duringthe review an independent team of engineers and ESA officials closelyscrutinised all theelements of the mission, including the ground stations, the spacecraft, thepayload ofscientific instruments and the launcher.
