Crashed and burned again due to only one of the 2 engines reigniting.


Wouldn't it be better to start all 3 raptor engines and turn off 1 that they don't need?
You won't be able to land on Mars without better landing gear than that. Far to small and unable to cope with ground movement.

I watched a few videos after the 1st one that talked to rocket engineers and the issue isn't the engines themselves the problem is supplying the fuel to them.

Due to the nature of the landing, the fuel moves and pools at the side of the tank rather than the bottom. Then getting the fuel back to where it need to be for the engines to use it properly.

I assume they are going to have to create some sort of smaller fuel tanks for landing that can start the engines before fuel tanks have settled and can be used to feed the engines properly again. but im sure they know better ways.

they will get there eventually.

Undoubtedly. A true rocket engineering problem.
It will be interesting to see what happens in zero g or low g because the fuel isn't going to move under gravity.

I think Musk will be expected to take on NASA, at least part fund it.

I'm all for space exploration but I'm not sure Biden wants to pump taxpayers money into it at this moment in time.

echoes of the Mk1 Spitfire - one of its drawbacks over the ME109 was that unlike the Messerschmidt which was fuel injected the Spitfire Mk1 had a carb so when you went inverted the fuel supply cut off and the engine stuttered - can you imagine the heart in mouth moment was you try and out manoeuvre an enemy who knew exactly what he had to do to cause it to happen and hoping that when you did it the plane would cough back into life? Its not like you could ask Binky and Strangely Brown to hop out of their Spits and bump start you at 12,000 feet is it lol?

great fix though

yeah its an interesting issue, im sure they will sort it.

the zero G stuff must have been fixed years ago mind you as we have had ships in space for ages.

Im wondering if they need to have some sort of fuel take that can compress as it empties to force the fuel to the right place.

And the merry go round starts again. Roads closed today for possible SN10 tests

SN11 nose cone fitted so I guess may make an appearance

Perseverance slams into Mars tonight. Good luck little fella, hope I’m not reading your obituary in the morning
