The British Beagle 2 spacecraft landed successfully on Mars' surface, David Parker, the chief executive of the UK Space Agency has confirmed.
The probe was thought lost after attempting a Christmas Day landing on the planet in 2003.
Artist Damien Hirst has shared his delight at hearing the Beagle 2 has been found and said he "can't believe" that the painting he had on board the missing spacecraft is now residing on Mars.
Hirst tweeted: "I have a painting on Mars! It's amazing!"
For 12 years Beagle 2 was feared lost but today it has been hailed after images showed the probe successfully landed on Mars in 2003.
