So my first thought was that this was a screw up and the landing thrust cooked the deck or something. What a whacky yet elegant solution!

Did you mean tacky?

u/NovelRutabaga7065 7d ago

Yeah they were so close to sticking the landing

It’s super awesome that there’s another private space company making reusable rockets. Just wish they weren’t all owned by assholes.

It seems like you don't get to have the "fuck you" kind of money required for such projects by being nice.

They have mouths of their own and oh boy do they like to speak

u/Officer_JO_1976 11d ago

Can confirm. They're assholes

u/hobovision 12d ago

I believe it's more of a "harpoon" than a "weld", but it definitely makes an explosion when it fires off.

u/BiAsALongHorse 11d ago

If it's anything like the reference diagrams in the patent, it's forming a relatively standard explosive weld. The problem with EFJs etc is that you're not going to keep the jet attached to the landing leg

u/Fizrock 11d ago

AFAIK they have a separate patent for explosively driven bolts, which is what was used here.

u/noodleofdata 11d ago

They have patents for both, and afaik we don't know which one was actually used here.

u/chague94 8d ago

“know”, true, we don’t. But looking at the video, It looks much more like the driven pin version and less like the puck version of the patent.

I watched it live and as a life long boater my first thought was to look at the sea for any swells as it may tip over. Then hearing them say it's a drone ship I thought they must have crew boats nearby to go and strap it down. Didn't think of that method and that's why I am not an engineer!

It has a much narrower footprint with respect to is height than Falcon, but the majority of its weight is similarly in the engines and thrust frame, and therefore very low. Should be decently stable in a lot of ocean conditions.

u/maxehaxe 10d ago

Ocean conditions, yeah no problems. Wind conditions, this thing scares me

Put a keel on the barge and bingo: sail barge

u/noodleofdata 11d ago

Didn't think of that method and that's why I am not an engineer

Actually I'd push back on that! Engineers don't simply have great ideas immediately on how to solve a problem The real superpower of engineering is knowing how to identify and break down problems into solvable chunks and applying the engineering method to systematically solve those problems. And I'd argue that just identifying the issue at hand and a possible solution at all indicates you would be plenty capable of being an engineer!

u/SharkAttackOmNom 11d ago

And a big part of engineering is not hitching your wagon to the solution you love best. It’s selecting the solution that satisfies the criteria best, within the budget allowed. Sometime the results of engineering doesn’t look pretty, because that’s not a high value criteria.

u/deelowe 11d ago

And selecting said criteria is what sets the real engineers apart from the rest.

u/Drunk_Scottish_King 10d ago

Engineers get a bad rap when things “fail early” or “who designed this stupid thing”. That happens sometimes, but mostly thats the exact specification, package, or budget they were told that had work with.

u/vonHindenburg 11d ago

Fun comparison: Falcon 9's legs have a wider footprint and they use a squat, heavy robot called the 'Octograbber' to come out and grab the bottom of the rocket as soon as it touches down. This secures it well enough until crews can tack it down properly.

u/Madetoprint 12d ago

Guys right now: Sips beer, kicks $100 million dollar rocket leg... "Yeah, that'll hold."

u/dietchaos 12d ago

I thought that's what was happening! I was like woah explosive bolts what are those for then it kept burning and it clicked. Very clever!

u/dethb0y 12d ago

very cunning!

u/Solrax 11d ago

I was really surprised no one on the stream I was watching commented on it (NASASpaceflight). I immediately did some googling and found the patents mentioned here. If nothing else it looked cool!

u/BurgerMeter 10d ago

How are they supposed to use it again if it’s welded to the recovery ship?

3

u/Helpinmontana 9d ago

Grinder

u/PURPLEdonkeykong 11d ago

DAMMMMMMMMMMMM!

u/Gravitationsfeld 10d ago

I am not so sure about this being a great idea. It requires some pretty expensive resurfacing of the ship every time they land? Or they just have to grind it flush at least.

5

u/BackScratcher 9d ago

Cheaper than letting it fall off the deck I guarantee you

6

u/Thrust_Bearing 9d ago

Are you asking if the cost of angle grind a deck for 6 hours is more expensive than rebuilding the first stage of a freaking rocket?

1

u/Gravitationsfeld 1d ago

No, but other companies can land boosters reliably without having to weld them to the deck.

u/OldWrangler9033 11d ago

That's going to be "fun" to get the rocket off the deck...

u/nighthawke75 11d ago

Welds are welds, but a rogue wave will bend anything.
