Assuming no issues with the flying debris SN10 should fly before the end of the month, according to the host on the SpaceX livestream.

Another launch and I'll bet money they stick the landing. You have to have data so you can fix what is wrong. I applaud the engineers working for space x.

Also to note it crashed on the landing pad so it was where it was supposed to be.

I am no rocket surgeon but I am wondering if it's possible for one engine to land it safely. I would think it could generate enough lift.

Obviously there are controls to get it on target and to throttle up and down. Maybe some failsafe kicks in to let the one engine do more work?

I am sure they will figure something out, just something I thought of.

If do wonder if they started that Crazy Elon flip maneuver at a higher altitude whether that would give them enough extra time to take helpful actions in the event of engine problems.

I think right now its just to much velocity coming down for one engine. They said the plan is to not land at all but to hover long enough for a landing arm to grapple Starship on earth. They do plan to land for a Lunar and Mars version.

A good landing is one where you can walk away from the airplane. A great landing is one where you can reuse the airplane. That was neither.

Was that in Texas or somewhere else? I think I would have heard that explosion if it were here at KSC.

Yall have to bear in mind that a vehicle like this has never been attempted in the history of spaceflight. There's going to be many more Starship test articles lost before they get this right and I'm not referring to just hopping and landing successfully. They have to test the re-entry profile with the tiles, orbital re-fueling (never been done before), design new landing legs (Elon has alluded to this previously), test the software, PID, and state space controllers in all phases of flight, Environmental Systems (Because designing a rocket to support humans in deep space is VERY different from designing one for simply LEO) when they eventually do have crewed launches, etc.

BTW, what you're seeing now is only the 2nd stage. They also have to test the Super Heavy Booster and everything else associated with that, which will place Starship on a sub-orbital trajectory. At the end of the day, this thing will be bigger than a Saturn V. Below is a graphic drawn to scale demonstrating the sheer size of this vehicle.

Actually, it can't land on one engine. With only one engine Starship loses roll control and doesn't have enough thrust to slow down in time.

You can see here in this footage of SN8 how the 2 engines are working together, gimballing like crazy place to keep it stable:

They launch out of Boca Chica, TX, way down at roughly the southernmost tip of Texas bordering the Gulf of Mexico.
