ESA provides personnel to the Space Telescope Science Institute (STScI) as part of its collaboration with NASA onthe Hubble Space Telescope (HST). Some of this personnel are funded from the Space Telescope Division,Directorate of the Scientific Programme of ESA, through a contract with the STScI.

The closest approach during the sole targeted flyby of Hyperion occurs on Monday, 26 September, at 02:25 UT at an altitude of 514 km above the surface and at a speed of 5.6 kilometres per second. Hyperion, roughly 1/3 the size of its round neighbour Tethys, is one of the smaller moons of Saturn and is shaped like a potato with the diameter of the long axis being 360 km and diameter of the short axis are around 250 km.

The Tethys flyby is technically non-targeted (meaning there are no manoeuvres solely designed to control the flyby trajectory); however, through efforts recently made by the Cassini navigation team, this encounter was able to be lowered to allow for a close study of the icy moon.

The Millennium Star Atlas is to be reprinted in a soft cover version. The Atlas contains 1548 sky charts, depicting the heavens with unprecedented information on the nature of our Galaxy using the stellar information drawn from ESA's Hipparcos and Tycho Catalogues.

On 27 December 2004, radiation from the biggest starquake on a neutron star ever recorded reached Earth. Unique data obtained by Double Star TC-2 and Cluster satellites enabled a group of European scientists to find the first observational evidence of cracks in the neutron star crust, during the initial phase of the starquake. This result, published 16 June 2005 in the Astrophysical Journal, dicriminates between current theories on the physical origin of such massive starquakes.

Observations with the Hubble Space Telescope have revealed the presence of a compact disk of young stars at the heart of the Andromeda galaxy surrounding the central black hole.

A large study of quasars conducted with Hubble and the VLT has resulted in the first observation of a unique type of quasar, one with no readily observable host galaxy.

Titan-7 is the eighth targeted encounter of Saturn's largest moon. The flyby occurs on Wednesday 7 September at 08:12 UTC. The closest approach will be at an altitude of 1075 km above the surface at a speed of 5.9 km s-1. Titan has a diameter of 5150 km, so the spacecraft passes just a Titan radii. The phase on approach is approximately 50°, reaching 85° at closest approach, and is approximately 128° outbound. The lower phase angles are good for the Cassini cameras.

On 9 August 1975 ESA's first scientific satellite, Cos-B, was launched. Cos-B was ESA's first foray into producing a spacecraft with a single payload: a high-energy gamma-ray telescope. The mission was a remarkable success and returned the first detailed observations of gamma-ray emission from within our galaxy.

Titan-6 is the sixth close flyby, and seventh targeted encounter of Saturn's largest moon. The flyby occurs on Monday 22 August at 08:54 UTC. The closest approach will be at an altitude of 3669 km above the surface at a speed of 5.9 kms-1. The latitude at closest approach is -59°.
