Shuttle Discovery: Review of 39 missions
The US shuttle Discovery has launched from the Kennedy Space Center for the last time.
First launched in 1984, this is its 39th outing. When it lands back on Earth in nearly two weeks' time it will have covered a cumulative career distance of 230m km (143m miles).
That is further than the distance from the Earth to the Sun (149m km).
Andy Gallacher looks back at the missions performed by the orbiter.
