Starship is on the launch tower at Elon Musk’s Starbase spaceport in Boca Chica, Texas, as we count down to its third test flight.
The launch is due to take off in the early morning local time, providing there are no last minute delays, or 12pm UK time.
The livestream should begin roughly 30 minutes before lift-off, when we should get more details on the mission ahead. We will feature the livestream right here in our live blog, but you can also watch it on SpaceX’s website.
All being well, the rocket should launch around midday. The rocket booster, which is designed to be reusable, will separate and fly back to earth.
Then, the main stage should carry on to the edge of space, before performing a series of tests including opening its payload hatch.
It should then reenter above the Indian Ocean before splashing down into the sea for an “exciting landing”, SpaceX says.
