Should be amazing to see - is this the largest amount of rocket power ever unleashed?  Think so.

Apparently a successful test firing will entail not blowing up the launch pad which has cost in the region of $1B!!

If they get this machine to work and land it’ll be amazing. What a rocket!

I thought this was another mockup like the hopper etc but I just realised that it's the booster that's officially, theoretically, possibly going to carry the orbital test flight. It just looks like a bin, is all.

What time?

That is a really tedious channel. They clearly have no idea what is going on and are just guessing. But, given there's no official stream from SpaceX I suppose that's all we have.

What time?

Hours off yet, they've not even loaded the propellant.

Le Fridman had Tim Dodd on his podcast this week, a five hour marathon.

Rocket science,  turns out it's pretty tricky.   The scale of what they're doing is pretty mind boggling.

It's not something I'm into,  and didn't expect to find it so interesting,  but the whole thing is fascinating.

Impressive also how routine the launches and landing of existing rockets has become.

It's like golf, except hopefully with a big whoosh/boom at the end. Especially compared to launches this one's lacking info, they don't have the usual countdowns etc and because nothing's flying they don't need the same clearances etc. Basically if you tune in hours before the test, you're going to watch hours of pre-test

They still need certain clearances.... Road closures, possibly airspace also.

There's a lot of guesswork involved re the timings as they don't publish them.

The guys at NSF have created a timeline based on certain things happening so can usually nail it down to a 30 minute window if so goes according to plan.

Big buildup for two seconds of action.... A bit like sex really!

31 engines fired. 1 out before start and 1 cut out join firing.

Promising first test then. With so many engines, anyone know if there's any redundancy? I'd assume they'd need all firing correctly for a full launch

They did say in the commentary 31 would be enough to put it into orbit and they did fire it for the full duration that was planned.

Yep I think they have a little margin for error and can afford to lose an engine or two.  I know F9 has launched previously and lost an engine without any orbit issues.

that is a big cloud of dust!  I'm excited to see more than a two second burst, raptor plus booster to orbit is going to be INCREDIBLE!!!!!!

very excited. 🚀🚀🚀🚀
