Royal Mail have released six stamps to celebrate 50 years since Britain's first satellite, Ariel 1, was launched. This stamps shows the Lutetia asteroid.
The satellite was launched on 26 April 1962 and took 100 minutes to orbit the earth. This stamp shows a crater on mars with ice in it.
All the images on the stamps are from missions run by the European Space Agency. This shows the rings surrounding the planet Saturn.
The UK was the third country to launch a satellite and it was a big deal because it was the first time Britain had launched something into space. Here on this first class stamp, the intensity of the Sun is shown.
On board the satellite were six experiments with equipment to measure radiation from the sun. This stamp shows the green glow on Titan, which is the largest moon of Saturn.
Ariel 1 travelled around the planet until April 1976, when it crashed to Earth. All of the stamps, including this one of the planet Venus go on sale in Post Offices on 16 October.
