The next Starship megarocket to fly is stuck on Earth for a little while longer.
SpaceX aimed to launch the eighth test flight of Starship — the biggest and most powerful rocket ever built — from its Starbase site in South Texas on Monday evening (March 3).
That didn't happen, however. The company encountered issues with both of the vehicle's elements — its Super Heavy booster and Ship upper stage — and called the launch off after holding the countdown clock at T-40 seconds.
SpaceX didn't specify during its launch webcast what the issues were, and it wasn't immediately clear when the company would try again to launch Flight 8.
"Standing down from today’s flight test attempt. Starship team is determining the next best available opportunity to fly," SpaceX wrote this evening via X, the social media platform owned by company founder and CEO Elon Musk.
On Tuesday morning (March 4), SpaceX announced via X that it's targeting Wednesday evening for the liftoff, during a window that opens at 6:30 p.m. EST (2330 GMT). You can watch the action live here at Space.com, courtesy of SpaceX.

Starship Die Cast Rocket Model Now $47.99 on Amazon.
If you can't see SpaceX's Starship in person, you can score a model of your own. Standing at 13.77 inches (35 cm), this is a 1:375 ratio of SpaceX's Starship as a desktop model. The materials here are alloy steel and it weighs just 225g.
SpaceX is developing the fully reusable Starship to help humanity settle the moon and Mars, among other spaceflight feats. The giant rocket debuted in April 2023 and now has seven test flights under its belt.
Its most recent mission, which occurred on Jan. 16, featured both successes and failures. For example, SpaceX caught the returning Super Heavy back at Starbase with the launch tower's "chopstick" arms, but Ship was lost after developing propellant leaks less than 10 minutes into flight.
The upper stage ended up exploding over the Atlantic Ocean, providing a dramatic sky show for people in the Turks and Caicos Islands and nearby areas.
Ship was supposed to deploy a set of dummy Starlink satellites on Flight 7. SpaceX will try again to do this on Flight 8; the goals of the mission are similar to those of Flight 7.
If all goes according to plan, Super Heavy will nestle into the launch tower's inviting arms once again, and Ship will fly much of the way around Earth before making a soft splashdown in the Indian Ocean off Western Australia.

m4n8tpr8b SpaceX didn't specify during its launch webcast what the issues were
Lack of transparency, as usual. I would also be curious how the decision to delay came about (how much interference there was from Elon). -

Seriously?! Musk did not seem to have any involvement in the launch process. And the announcers specified the various problems were in the booster or the Ship. I expect the actual problem explanation would take a lot of education that the public does not have in order to be usefully understood. So, the various issues are not likely to be something that can be clearly communicated to the public in real time during a countdown. We will probably get some better explanations later, if anybody asks.m4n8tpr8b said:Lack of transparency, as usual.

I just came to this story to see if the next launch attempt has been scheduled. -

If Musk wasn't present and the engineers could decide on their own, that's actually a positive.
I'm sorry but the public consists of people with different levels of expertise and they could very well have given an explanation, like other launchers do. "Various problems both in the booster & the second stage" is not an explanation, it just indicates that there was more than one problem. It is very much of public interest to know what kind of multiple problems could escape attention until shortly before launch. -

With the amount of fuel on board, if it slams to the ground before burning up most of its fuel, the blast radius would be huge. If it ever blows up on the launch pad, it will demolish everything in a large radius. Read up on the Nedelin disaster; a Starship+Superheavy explosion would be much bigger, the same level as a small nuclear weapon.Brad said:<<Removed by moderator>> -
Unclear Engineer SpaceX has actually given the public much more information, and much faster, than other launchers. For one thing, this is a development process, not the scientific missions that NASA typically showcases. And, we get to see in-flight video of both the booster and the Ship, including flap burn-throughs, etc. NASA does not even have the Starlink capability to do that unless SpaceX provides it for them. And, we see real-time graphics of propellant levels, altitude, velocity, vehicle attitudes, etc.Reply
Complaining that we don't get real-time explanations of every potential hold issue is ridiculous. And, if you were listening to the engineering and launch crews radio coms, you would probably not understand nearly all of the jargon and equipment references, anyway. There will probably be some explanation of the actual cause for the scrub, later. You don't have any reason to get involved in anything else.
As for the blast radius of an on-pad explosion of a fully fueled Super Heavy + StarShip, see the discussion at https://www.quora.com/How-big-would-the-explosion-be-if-a-fully-fueled-StarShip-Super-Heavy-exploded-on-launch . I am not going to get involved in doing those calcs, myself, because I expect that the FAA has already done that, and probably NASA and the Air/Space force for the Florida launch sites. -
