SpaceX has confirmed that the four-hour window for the spacewalk will take place at 05:58 ET (10:58 BST ) 'Back home we have a lot of work to do, but from here Earth sure looks like a perfect world,' said billionaire Jared Isaacman as he stepped out into space.

Isaacman and mission specialist Sarah Gillis have both now exited their spacecraft.

The hatch has now been closed and pressure has began to return to the Dragon capsule.

This needs to be done extremely slowly so that the huge changes in pressure do not cause any health complications for the astronauts.

When astronauts enter the vacuum of space the sudden drop in pressure can cause dissolved nitrogen in the blood to expand into bubbles.

These bubbles can cause a condition called decompression sickness, otherwise known as the Bends , which can be fatal in severe cases.

None of the crew except for Isaacman have ever been in space before.
