Shuttle Discovery’s last docking at the ISS

America's longest serving space shuttle, Discovery, has docked with the International Space Station for the last time.

­This trip to space is set to be the ship’s last, as the US retires its quarter-of-a-century-old fleet.

The shuttle delivered tens tons of cargo and scientific equipment to the ISS.

It also presented a rare photo-op, as six different spaceships are now docked at the ISS.

Upon its return to Earth, it will be ferried off to a museum, where it will soon be joined by its sister ships Endeavour and Atlantis.

The decommissioning will effectively end manned US spaceflight.
