Any minute now, US space agency NASA will send its first Orion space capsule thousands of miles above Earth before it descends into the Pacific Ocean. The event will pave the way for manned missions deep into space.
It is envisaged that this means astronauts could be zooming from Earth to Mars by the 2030s.
Today’s Flight, called Exploration Flight Test-1 (EFT-1), will travel 5,800 kilometres (3,600 miles) from Earth before rocketing back and descending into the Pacific Ocean, where NASA will hopefully retrieve the capsule.
The purpose of the mission is to test the capsule’s heat shield, avionics and other systems.
And you can watch it live, here.
