Britain's Tim Peake Begins Spacewalk

Tim Peake said it was a "privilege" when he became the first Briton to walk in space after venturing outside the International Space Station (ISS) to fix a broken power unit.The spacewalk, which began just after 12.55pm GMT, will last almost six-and-a-half hours.
As he prepared to exit the air lock, one of Major Peake's colleagues, Commander Scott Kelly, remarked it was "really cool" to see the Union flag outside.
Mr Kelly said: "The Union Jack has explored all over the world, now it's exploring space."
Major Peake replied: "It's great to be wearing it. A privilege, a proud moment."
His wife, Rebecca Peake, left a short message for her husband as he left the ISS.
"@astro--timpeake thank you for taking our boys with you into the vacuum of space," she wrote on Twitter.
Back on earth, well-wishers also took to Twitter to express amazement and wish the astronauts good luck.
