Landed right next to a flying drone. How much more perfect X marks the spot could you get?

NSF just mentioned the "Gateway to Mars" sign took some damage.

I think they said it only says "Gate to Mars"


Correction, only says "Gat way "

That was a cool view of the underneath side before it exploded.


Those tiles looked pretty good

Either by design changes or because they finally didn't intentionally create failed points, the fins didn't have any burn through issues.

Awesome landing.

Just the idea of being in the Indian Ocean an hour after leaving South Padre is wild.

That was fun. Curious on the booster failure, though. I thought they had that mostly set at this point. No?

All new Raptor 3 engines, completely new fuel management plumbing inside.

This rocket system "looks" mostly the same, but everyone has said it's a complete clean sheet redesign of Version 2.

Blue stars to SpaceX for a very successful test flight. They overcame some anomalies and still achieved their goals. This is important right before the stock goes public. Let's all get rich!

Big difference in power it seems.
1001 km/h vs 817 km/h
5.1km alt vs 4.3 km alt

Time to velocity would suggest ~20% increase in TWR

I wonder if that flip didn't result in fuel flow disruption. The down comer for the methane fuel is the diameter of a Falcon 9 fuselage!

Was that flip and specifically the exact execution, fully by design or did the thrust reaction from ship push booster off nominal?

So basically the same?

Haha, thanks for the response.

The sweet, sweet mushroom cloud of success!

I honestly didn't expect that they'd hit the drone bouy target with the early loss of the R Vac. That was a very impressive, unintentional, demonstration of their engine out capability.

Yes, but it's more complicated than that.
1. The Raptor 3s shed a lot of weight off the booster.
2. They add ~10% more thrust, currently.
3. SpaceX used the weight savings and the integrated hot stage ring to move the common dome up and move the top of the LCH4 tank up into the hot stage ring. They added 400 tons of fuel doing this.
4. They had significantly more payload mass in this stack than in any previous.
5. The real big difference in jump off the pad is largely this.... The flame trench and new deluge system allowed for a redesign of the hold down clamps as an active system. They're now holding the full stack to the pad until all 33 Raptors are at full thrust, then they loose it. Before, they had to let it go because the hold downs had to release before ignition and the pad couldn't take the beating of waiting for the Raptors to throttle up to full thrust.

I have to assume the majority of those young engineers based out of California are pretty far left. Its good to see them chanting USA.

I really want to get down there to see one of these launches. We are in CS, guess I need to plan a week vacation around the next one. Do we have any idea when they will be?

Not many are worried. I dont think we should be frightened by that.

Don't believe the algorithm, Americans are way more similar than we are different.
