The launch of Atlas Centaur 121 and the SOHO spacecraft was scrubbed just prior to tower rollback at approximately 03:45 UT 23 November due to a malfunction of an Atlas booster precision regulator, which will require removal, replacement and failure analysis of the probable cause. The regulator provides reference pressure to control booster engine thrust. No decision on rescheduling has been made at this time.

The hydrazine thrusters on ESA's Infrared Space Observatory have successfully raised the perigee Of ISO's orbit from 518 km to the operational altitude of 1030 km above the Earth. Commands to he spacecraft's thrusters were sent from ESA's Control Center ESOC in Darmstadt Germany at 13: 10 UT on 19 November. The thrusters were used for a total of 111 minutes and the burn finished at 15:01 UT.

The European Space Agency's Infrared Space Observatory (ISO) has a rendezvous with the unknown on 2 November 1995. The 2.5 tonnes satellite will be launched by an Ariane 44P from Kourou, French Guiana on 11 November 1995 at 01:42 UT. Its task will be long-duration observation of celestial radiation sources in the invisible and cool light of infrared radiation, as yet largely unexplored.

The Sun, our nearest star, will be studied in unprecedented detail when the European Space Agency's SOHO spacecraft is launched by NASA later this year. The name SOHO is an acronym for the SOlar and Heliospheric Observatory. SOHO was also a medieval Anglo-French hunting cry; but this time the hunt is for answers to basic questions about the sun.

The International Ultraviolet Explorer (IUE) spacecraft, launched in January 1978, is one of the longest living and most successful spacecraft ever launched. For 18 years the IUE spacecraft was operated jointly by ESA and NASA, where spacecraft control and science operations were distributed with 16 hours science operations from the NASA IUE observatory at GSFC in Maryland and 8 hours from the ESA IUE Observatory at VILSPA near Madrid, Spain.

That mission is now set to start on 8 November. Rising into the Kourou sky, launched by Ariane, will be a satellite keenly awaited by astronomers wound the world: ISO, the first real infrared space observatory, built and launched under the responsibility of ESA. its task will be long-duration observation of celestial radiation sources, studying them with unparalleled sensitivity and precision. It will view them in the invisible and cool light of infrared radiation, as yet very largely unexplored. ISO will provide an entirely fresh perspective on the universe. This should provide a major and significant boost to scientists working in many areas of astrophysics, from nearby planets to the most distant quasars, taking in star formation, the dark matter of the universe and superluminous galaxies.

One of the European Space Agency's most remarkable scientific missions, Hipparcos, completed a significant milestone in its triumphant progress last week, when the group of European scientists responsible for it met with ESA representatives in Paris for a comprehensive review of the project's scientific progress. Just two years after termination of satellite operations they have announced, to their joint satisfaction, that the lengthy process of compiling the largest and most accurate catalogue of star positions ever has been completed.

This picture taken by the European Space Agency's faint object camera on-board the Hubble Space Telescope resolves, for the first time, one of the smallest stars in our Milky Way galaxy. Called G1623b the diminutive star (right of center) is ten times less massive than the Sun, and 60 000 times fainter. (If it were as far away as the Sun it would only be eight times brighter than the Full Moon).
