Key moments from first non-professional spacewalk

Billionaire businessman Jared Isaacman has become the first non-professional astronaut to walk in space during the Polaris Dawn mission.

“Back at home we all have a lot of work to do, but from here Earth sure looks like a perfect world,” he said as he stepped out into space for the first time.

Carrying four private citizens, the SpaceX’s Falcon 9 rocket launched into space on Tuesday and will spend up to five days in orbit.

Mr Isaacman funded the mission, which is the second privately-crewed mission from SpaceX – the spaceflight company founded by Elon Musk.

Their spacecraft, called Resilience, will go into an orbit that will eventually take them up to 870 miles (1,400km) above the planet. No human has been that far since Nasa’s Apollo programme ended in the 1970s.
