A few small steps for Tim Peake as he walks into history...

Tim Peake's historic spacewalk outside the International Space Station had to be cut short for safety reasons.

Former Army Major Peake became the first official UK astronaut to go on a spacewalk and was due to fix a broken solar shunt, which transfers electricity generated by solar panels.

The mission was ended after four of the scheduled six hours because fellow astronaut Tim Kopra reported seeing a water bubble in his helmet.

The walk was still a major landmark for British space exploration and was watched live from Tim's primary school in Emsworth, Hampshire.

Our reporter Sam Holder watched Tim start his walk with pupils at Westbourne Primary School.

History was made today - as Sussex army major, Tim Peake, became the first official British astronaut - to walk in space where he fixed a power unit, outside the International Space Station. His space mission was expected to last six and a half hours but was terminated early because of problems with the helmet of his fellow spacewalker, Tim Kopra. But for schoolchildren across the South East the spacewalk provided a 'live' science lesson that was, out of this world. Wellesley House School at Broadstairs in Kent was one school where pupils were watching with great interest. Andrea Thomas has been speaking to some of them, along with teacher Kerry Sabin-Dawson.
