Starship launch latest: SpaceX set to fire up world's biggest rocket ...

SpaceX has begun the broadcast of its live stream for today’s Starship launch attempt.

If you’re just joining us, you can watch a replay of the lift off right here:

You can hear the SpaceX staff cheering in the background. It’s an impressive sight, with SpaceX’s live stream commentator describing it as a “phenomenal test”.

Starship is ticking off objectives as it coasts around the planet. The latest is the opening of a hatch that will one day be used to deliver satellites into orbit.

It’ll be another 40 minutes or so before we see any major action from the rocket, with T+50 minutes the scheduled time for reentry into the Earth’s atmosphere.

“We’re farther than we’ve ever been before,” a SpaceX commentator says on the live stream.

“We did lose the booster... but wow, a ship in space. We’ve got a bunch of ambitious objectives over the next hour. We’re going to try and learn as much as possible.”

The Super Heavy booster appears to have been lost, shortly after it was meant to splash down in the Gulf of Mexico.

The upper stage is still continuing on its planned flight path.

Starship has successfully separated from the Super Heavy booster, which was the point the test flight failed on the first attempt.

The second stage is continuing to follow its flight plan, and has made it further than the second attempt, which failed shortly after a successful stage separation.

SpaceX says this third test has been a “phenomenal test so far”.

We have lift off!

It looks like winds aren’t going to prevent the launch today. SpaceX says they’re “cooperating”.

The countdown is less than 1 minute.

We’re hopefully entering the final stages of the countdown, as the clock passes 10 minutes.

It’s a lot lighter out there than it was an hour ago, when Starship was originally scheduled to launch. That means we’ll hopefully get a better view of the launch, so long as the fog doesn’t get in the way too much.

Speaking of views, this camera at the top of Starship shows just how tall it is. Measuring 120 metres, it’s 24 metres taller than Big Ben’s tower in London.
