A scientist from the University of Leicester has led a 2.5 billion dollar mission to land a spacecraft on Mars.
Dr John Bridges led the team from Leicester, the Open University and the French National Centre for Scientific Research.
The six-wheeled robot, Curiosity, landed safely on the surface of Mars at 06.33 am.
It will now begin two years of scientific work, to try to find clues as to whether there could be life on the Red Planet.
To the entire team & fans back on Earth, thank you, thank you. Now the adventure begins. Let's dare mighty things together! #MSL
From 10:00 this morning, The National Space Centre will be showing live coverage from NASA, and there will be live interviews from the US and UK with scientists working on the project, including Dr John Bridges.
