HST’s 10th anniversary – ESA and Hubble : changing our vision

To mark the Hubble Space Telescope’s tenth anniversary, ESA is hosting a press conference at the Space Telescope-European
Coordinating Facility (ST-ECF) in Munich on Thursday April 27.

With the astronauts who took part in the most recent Servicing Mission (SM3A) in attendance, ESA is taking the opportunity to give
a – first – complete overview of Europe’s major contribution to the HST mission. It will also review the first ten years of operations
and the outstanding results that have “changed our vision” of the cosmos. A new fully European outreach initiative – the “European
Space Agency Hubble Information Centre” – will be presented and officially launched; it has been set up by ESA to provide
information on Hubble from a European perspective.

A public conference will take place in the afternoon to celebrate Hubble’s achievements midway through its life.

Ten years of outstanding performance

Launched on 24 April 1990, Hubble is now midway through its operating life and it is considered one of the most successful space
science missions ever. So far more than 10,000 scientific papers based on Hubble results have been published and European
scientists have contributed to more than 25% of these.

Not only has Hubble produced a rich harvest of scientific results, it has impressed the man in the street with its beautiful images of the
sky. Thousands of headlines all over the world have given direct proof of the public’s great interest in the mission – ‘The deepest
images ever’, ‘The sharpest view of the Universe’, ‘Measurements of the earliest galaxies’ and many others, all reflecting Hubble’s
performance as a top-class observatory.

The Servicing Missions that keep the observatory and its instruments in prime condition are one of the innovative ideas behind
Hubble. Astronauts have serviced Hubble three times, and ESA astronauts have taken part in two of these missions. Claude Nicollier
(CH) worked with American colleagues on the First Servicing Mission, when Hubble’s initial optical problems were repaired. On the
latest, Servicing Mission 3A, both Claude Nicollier and Jean-François Clervoy (F) were members of the crew.

Over the next 10 years European scientists still plan to use Hubble as one of their prime research tools, but they also expect to benefit
from synergy between Hubble and the ground-based 8-metre class telescopes that are becoming available to scientists in Europe.

Notes for editors

The Hubble Space Telescope is an international cooperation project between the National Aeronautics and Space Administration
(NASA) and the European Space Agency (ESA).

The partnership agreement between ESA and NASA was signed on 7 October 1977. ESA has provided, among other items, two
pairs of solar panels and one of Hubble’s scientific instruments (the Faint Object Camera). 15 European scientists are contributing to
the science operation of the Hubble Observatory and are currently working at the Space Telescope Science Institute in Baltimore
(STScI). In return for this contribution, European astronomers have guaranteed access to 15% of Hubble’s observing time.

Scientific operation of the Hubble Observatory is the responsibility of the Space Telescope Science Institute, which is run for NASA
by the Association of Universities for Research in Astronomy (AURA).

The Space Telescope European Coordinating Facility (ST-ECF), hosted by the European Southern Observatory (ESO) in Garching
near Munich, Germany, provides support to European Hubble users. ESA and ESO jointly operate ST-ECF.
