“Starship Overview

SpaceX’s Starship spacecraft and Super Heavy rocket – collectively referred to as Starship – represent a fully reusable transportation system designed to carry both crew and cargo to Earth orbit, the Moon, Mars and beyond. Starship will be the world’s most powerful launch vehicle ever developed, capable of carrying up to 150 metric tonnes fully reusable and 250 metric tonnes expendable.”

Size comparison with Apollo.

The first attempt at a full launch is due tomorrow evening our time. It is planned to orbit, re-enter, “fly” down to near the surface, rotate to vertical and try to “land” vertically on the surface of the ocean. It will then fall over and likely be recovered.

There are many modes of failure, rocket science is hard. It would be very unlikely that it worked first time, but we can only hope for the best.

“ 150 metric tonnes “

Ugh, really?

It’s also completely unsuitable for going any further than Mars or Venus. Chemical rockets don’t have anywhere near enough performance to make them a viable system of going further.

Great to know that he still has some friends. :-)

One of the mathematical discoveries that I made while looking into rocket design is that for a well-designed rocket, the longer the rocket, the further it can go. The diameter of the rocket is almost irrelevant, ditto its total mass, it just has to have a large enough diameter to stop the rocket from bowing like a banana.

This design is exceptionally long.

It will go far.

They are saying it was a deliberate test.

That would help back it up.

The SpaceX Starship explosion was deliberate
https://mashable.com/article/spacex-starship-flight-test-explosion-on-purpose

Seems they left off 7 of the rocket cones deliberately.

How easily do they fall off?

from the link

In a statement(opens in a new tab) released after the incident, SpaceX said Starship climbed to about 26 miles over the ocean before beginning to lose altitude and tumble. Then, self-destruct commands were sent to the booster and ship, which hadn’t separated as planned, the company said.

In terms of the explosive ending, Dumbacher said spaceport safety officers are required to terminate a flight if a rocket meanders into an area where the risk of debris hitting someone on the ground could exceed a probability of one in 30 million.

“People ought to be looking at this as good — the flight termination system, if it was needed, actually worked,” he said.

To test the flight termination system.

Which worked.

Have you missed the many photos of the launch pad being nearly destroyed? At least one engine was out very shortly after lift-off, I couldn’t see all of them but there was one for sure. The other engines failing happened later.

ok.

I guess we will have to wait for the cause/s.

I still maintain that the flip maneuver should be been tested on a much smaller rocket.

One thing they were particularly hoping for in this test launch was that the launch pad itself wouldn’t be damaged, much less destroyed.

So no, it wasn’t part of the plan.

I hear a car got damaged too.

You know that if you make the rocket small enough then it spontaneously executes Brownian flips right¿
