Two astronauts have completed the first commercial spacewalk and tested slimmed-down spacesuits designed by SpaceX, in one of the boldest attempts yet to push the boundaries of privately funded spaceflight.
Hundreds of miles above Earth and orbiting at close to 30,000km/h (18,600mph), the billionaire Jared Isaacman, 41, who chartered the Polaris Dawn mission, exited the space capsule at 11.52am BST on Thursday.
