The Juno satellite, which left Earth five years ago, had to fire a rocket engine in a tricky and precise manoeuvre in order to brake and become ensnared by Jupiter's gravity. Fran Baganal is a mission scientist for Juno and tells Adam Rutherford what measurements Juno is now in position to make.Space is full of junk left over from past space missions: from flecks of paint to used rockets, dead satellites, also debris from past collisions of space junk. This junk is speeding around the Earth at several thousand miles per hour. At those speeds even small pieces of rubbish just fractions of a millimetre across can damage communication satellites which are vital for the web, mobile phones, and satellite navigation on earth. The Surrey Space centre team are preparing to launch the world's first space litter-picking mission. The RemoveDebris team share their clean up designs with Adam.Researchers have had success growing b
