PR 51-1993: Hubble refurbished and ready for release
The Hubble Space Telescope spread its wings this morning clearing the way for the release of the orbiting observatory. The telescope's twin European solar arrays slowly unfurled as shuttle Endeavour passed 593 kilometres above the Atlantic and Indian oceans.

PR 50-1993: Hubble gets new ESA-supplied solar arrays
The Hubble Space Telescope was fitted with a new set of solar arrays after a 6.5-hour spacewalk by Tom Akers and Kathy Thornton. These unique power-generating wings, supplied by the European Space Agency, will power the telescope for at least the remainder of the decade.

PR 49-1993: Hubble Space Telescope Servicing begins
The servicing of the Hubble Space Telescope(*) began today with an eight-hour spacewalk. One of the telescope's twin solar arrays was successfully rolled-up at the end of the day but the second array, which had one supporting beam that was bowed and twisted, failed to retract. The astronauts will jettison the troublesome right-hand wing and then proceed with replacement of the arrays as normal.

PR 48-1993: Endeavour blasts-off on ambitious mission
The space shuttle Endeavour blasted off in a blaze of light this morning on the Hubble Space Telescope servicing mission(*). The spectacular pre-dawn lift-off, visible for hundreds of miles, occurred at 09:27 UT. The launch was delayed from yesterday due to high crosswinds but the weather co-operated today and the shuttle lifted off on time into a clear, moon-lit sky.

Hubble Space Telscope Deep-sky Survey Finds Interacting Galaxies in a Cluster
In one of the deepest celestial surveys yet made by NASA's Hubble Space Telescope, astronomers have discovered a small group of previously unknown, interacting galaxies estimated to be three billion light-years away.*Hubble caught the galaxies in an early stage of evolution, and so they offer new clues to developing a much clearer understanding of how galaxies have changed over time.

PR 43-1993: ESA confirms ROSETTA and FIRST
At its 68th meeting on 4/5 November 1993, ESA's Science Programme Committee endorsed the recommendation of the Space Science Advisory Committee to implement Rosetta, a comet rendezvous mission, as the third cornerstone and FIRST (the Far Infrared Space Telescope) as the fourth cornerstone of the Horizon 2000 programme. The launch dates will be 2003 and 2006, respectively. However, FIRST would return its scientific data earlier than Rosetta, as the travel time to the comet is rather long.

PR 37-1993: Hipparcos - Mission Accomplished
After more than three years of efficient and successful operations, communications with ESA's scientific satellite Hipparcos were terminated on 15 August 1993. The Hipparcos satellite, a purely European undertaking, and the first space experiment dedicated to the highly accurate measurements of star positions, distances, and space motions, was launched in August 1989. Targeted for an operational lifetime of two and a half years, more than three years of high quality star measurements were eventually accumulated, and all of the original scientific goals of the mission have been fully accomplished.

Hubble Space Telescope Finds a Double Nucleus in the Andromeda Galaxy
A team of astronomers using the NASA/ESA Hubble Space Telescope has discovered a "double nucleus" in the center of the neighboring spiral galaxy M31, located in the constellation Andromeda."Hubble shows that the M31 nucleus is much more complex than previously thought," says Dr. Tod R. Lauer of the National Optical Astronomy Observatories, Tuscon, Arizona.A nucleus is a dense clustering of stars at the very center of a galaxy.

PR 30-1993: Ulysses breaks latitude record
On 9 June 1993, ESA's Ulysses spaceprobe became the first spacecraft to reach a latitude of more than 32 degrees relative to the Sun's equator. In doing so, Ulysses broke the existing record held by Voyager 1, which is currently exploring the depths of space beyond the solar system at a distance of more than 50 AU from the Sun (1 astronomical unit (AU) = 150 million km).

PR 28-1993: INTEGRAL confirmed as next scientific mission
ESA's Science Programme Committee, meeting at the European Space Research and Technology Centre, ESTEC, in Noordwijk (the Netherlands) on 3 and 4 June 1993, has accepted the recommendations of the Space Science Advisory Committee and confirmed INTEGRAL (International Gamma-Ray Astrophysics Laboratory) as the second medium-sized mission (M2) within the framework of the Horizon 2000 scientific programme.

What Happens When Galaxies Collide? Hubble Space Telescope Finds New Surprises
The NASA/ESA Hubble Space Telescope (HST) has discovered a new population of exceptionally bright and young star clusters at the heart of a head-on collision between two galaxies.The orbiting telescope also discovered a rotating, pinwheel-shaped disk at the center of the collision. In the Hubble photo, the disk resembles a full spiral galaxy, seen face on. Yet the disk is only ten thousand light-years across, about 1/20 the diameter of the whole galaxy.

PR 13-1993: Searching for gravity waves in space
Three interplanetary spacecraft, ESA's Ulysses and NASA's Mars Observer and Galileo, now quietly heading towards separate destinations (the poles of the Sun, Mars and Jupiter respectively), may soon prove the existence of waves in the universe's gravitational field by bobbing on ripples in space like corks bobbing on ripples in a pond.

PR 12-1993: Space science experiments on board the Space Shuttle
With the countdown for the forthcoming D-2 mission on the Space Shuttle still running, ESA and European scientists are already preparing for ATLAS-2, the Shuttle's next mission. ESA sees its participation in this second flight of the "Atmospheric Laboratory for Applications and Science" as a further step in preparing for utilisation of the Columbus Attached Laboratory.

Dark Matter Found in a Typical Cluster of Galaxies
Astronomer John S. Mulchaey, of the Space Telescope Science Institute (STSCI) and fellow team members announced today the discovery of a huge concentration of mysterious "dark matter" with the ROSAT X-ray observatory satellite. ROSAT is an acronym for Roentgen Satellite, a joint project of Germany, NASA, and the U.K.)

Protoplanetary Disks Around Newly Formed Stars
The NASA/ESA Hubble Space Telescope has uncovered the strongest evidence yet that many stars form planetary systems.Dr. C. Robert O'Dell of Rice University, Houston, Texas and colleagues have used Hubble to discover extended disks of dust around 15 newly formed stars in the Orion Nebula, a starbirth region 1500 light-years away.

Peering Far Back in Time to Uncover the Secrets of Galaxy Evolution
Looking far away and far back in time, NASA's Hubble Space Telescope (HST) has found some suspected ancestors of today's galaxies. The Hubble pictures reveal that star-forming galaxies were far more prevalent in the clusters of the younger universe than in modern clusters of galaxies near us today.

Hubble Space Telescope Discovers a Disk Fueling a Possible Black Hole
Astronomers using the NASA/ESA Hubble Space Telescope (HST) have gotten their best look yet at the disk of material that surrounds and is being pulled into a suspected black hole. The disk is at the core of a galaxy in the Virgo Cluster 45 million light-years from Earth. Dr. Walter Jaffe of Leiden Observatory in The Netherlands said the disk is tipped about 60 degrees - enough to provide astronomers with a clear view of the galaxy's bright hub.
