BBC News, Science and Environment: Majestic shuttle in unique station image
The picture was taken by Italian astronaut Paulo Nespoli as he left the International Space Station in May in a Soyuz capsule to return to Earth.

Safety procedures mean the Russian vehicle would never normally be in transit when a shuttle is present.

It makes this the first-ever image of an American orbiter docked to the ISS.

Endeavour sits firmly on the bow of the station, which is moving across the surface of the Earth at a speed of 27,000km/h (17,000mph) and at an altitude of approximately 355km (220 miles).

Nespoli's camera is looking along the ISS's truss, or backbone, which carries the four sets of giant solar wings. The stern is occupied by Europe's robotic freighter - the Johannes Kepler ship.

The pictures were acquired on 23 May but were only released by the US space agency (Nasa) on Tuesday. They had been eagerly awaited by space fans.

Nespoli had spent a lot of time during his 159-day stay at the station taking pictures of Earth and life aboard the international outpost. Many of these images were posted on his mission Flickr account. It was widely expected therefore that the European Space Agency astronaut would get some excellent shots during the unique departure.

The timing and subject is also perfect. Endeavour is seen here making her final sortie into orbit, making the last big US assembly item delivery - a $2bn particle physics experiment known as the Alpha Magnetic Spectrometer. The seven-tonne machine now sits on top of the platform.

Endeavour was also the orbiter chosen to take up the first American segment of the platform when the project had just got started in the late 1990s.

The youngest of Nasa's shuttles returned to Earth on 1 June and will now be prepared for public display at a science museum in California. Sister ship Atlantis stands ready on the launch pad in Florida for a swansong of her own in July. Once her mission is done, no orbiter will ever fly again.

Nespoli's crewmates in the Soyuz were Russian cosmonaut and Expedition 27 commander Dmitry Kondratyev; and Nasa astronaut Cady Coleman.

Their replacements blasted off from Kazakhstan on Tuesday in another Soyuz vehicle. Nasa astronaut Mike Fossum, Russian cosmonaut Sergei Volkov and Japanese astronaut Satoshi Furukawa are scheduled to arrive at the ISS on Thursday, raising its complement once again to six individuals.

The venerable Soyuz will be the only way for astronauts and cosmonauts to reach the platform in the years following the retirement of the shuttle fleet.

Nasa hopes some US commercial carriers will become available in the middle of the decade.
