He's saying that a serial killer is worried about another serial killer that has moved next door.

In much of the world, the US is the devil for pretty legit reasons.

The US rocket program was Kickstarted by kidnapped nazi scientists.

The fascists were more imaginative than your so called democracy and the communists even sent the first satellite and man into space. You overrate democracy and migration too much.

Garbage.. Interesting that NATO Caucasians complain of Chinese colonization of the continent more than Africans.

The equipment cloud curse is real.

It's impossible to 100% 3D print one. Alot of that weight is in things like electrical cables, computer components, rubbers, and fasteners and fittings.

That 85-90% is all the main component mass. That's impressive.

considering the sun is becoming more active (peaking in 2024) there might be more solar storms coming

space X reuses Falcons a lot.

SpaceX's first 3D-printed rocket engine part already launched on the Falcon 9 rocket in January for the THAICOM 6 mission. One of the rocket's Merlin 1D engines contained a 3D-printed main oxidizer valve (MOV) body. The valve operated correctly with high-pressure liquid oxygen, withstanding high vibration and cryogenic temperatures. The printed valve body has better strength, fracture resistance, and ductility than a part made with traditional casting, as well as lower variability in material properties. It was also a lot faster to make, being printed in two days instead of several months. The valve is now qualified to fly on all Falcon 9 flights.

I still want the nuclear reactor-powered cars I was promised.

>Since repeatability is not great for printed parts that means each piece has to be thoroughly tested before use which adds expense of its own, or risk if you don't follow a full test program. I think we will see that reliability is a challenge with their approach.

85% printed by mass, including the engines. they fuse metal powder with lasers.

the only reason spaceX can turn a falcon9 around so quick is because they DO NOT need to test parts... they make many precise copies quickly.. no leaky fuel valves please.

i don't think so.. I suspect this booster is still flying.

Saturday’s mission marked the first time a Falcon 9 booster flew for a 12th time and brought the total number of Starlink satellites launched to over 2,300.

Relativity unveils Stargate 4th Generation metal 3D printer with horizontal printing capability

https://www.tctmagazine.com/additive-manufacturing-3d-printing-news/metal-additive-manufacturing-news/relativity-unveils-stargate-4th-generation-metal-3d-printer-/

Relativity says that its new Stargate printer technology ‘defies traditional printing constraints’ by moving horizontally as it feeds multiple wires into a single print head. The company is also confident that the Stargate 4th Generation technology are capable of printing a rocket with 100x fewer parts in a matter of months, while customised software and machine learning techniques are being developed to support the printing of more complex and larger metal products.

Cloudy Nights has some very good tips and tech.

We just got hit with these here in Finnish Lappland, very cool how they started with blue colors. Having worked previously in Kiruna, i agree you get used to them fast, but they are always beautiful

KP projected to be 6s both friday and saturday night. Projected 4 tonight. So, tomorrow night and saturday night are the heavy hitters.

And their not so stealth anymore colonisation of Central and Southern Africa

That's very close to the mark for the primary issue in their use for launch vehicles. Since repeatability is not great for printed parts that means each piece has to be thoroughly tested before use which adds expense of its own, or risk if you don't follow a full test program. I think we will see that reliability is a challenge with their approach.

Why doesn't the article make any mention of Max-Q? Why doesn't the article make any mention of what Relativity Space had to say about it, perhaps on their social media? Why does the article appear rife with language like "fails just three minutes into flight", "far short of orbit", "as it turned out, the first stage did it's job...", and "although the upper stage malfunctioned and didn't reach orbit", when there's actually major milestone, and a lot of successes you can point to from this launch event.

From Relativity Space's Twitter - "Today’s launch proved Relativity’s 3D-printed rocket technologies that will enable our next vehicle, Terran R. We successfully made it through Max-Q, the highest stress state on our printed structures. This is the biggest proof point for our novel additive manufacturing approach. Today is a huge win, with many historic firsts. We also progressed through Main Engine Cutoff and Stage Separation. We will assess flight data and provide public updates over the coming days. #GoodLuckHadFun"

Why is that the AP is framing this is a loss when this is a pretty big milestone in their work?

Is this NOT exciting!?

I think you can do better.

did the layers delaminate as usual for 3d printed parts?

Also, if you want to pretend to be an American, you probably should erase your post history which is literally nothing but pro-China propaganda. lol.

Look at his post history. This guy is about as American as chairman Mao.

What a ridiculous comparison. If a person who murdered their last 10 neighbors moves in next door, you have a reasonable fear that they will murder you and if you have an ounce of logical, you will take precautions against that happening. If a random person, who has never murdered someone, moves in, it would be silly to fear being murdered by them.

You are saying that the person with the neighbor murderer next door is as unreasonable as the person who is paranoid for no reason.

The entire South China Sea

"First 3d printed rocket hits major milestone" or "one step closer to first 3d printed rocket reaching orbit". Come on, AP. Do better

I mean… their main goal was to make it past max Q because it was the rocket’s first-ever flight and they got all the way to stage separation before the second stage engine failed… All told it was a pretty successful flight.

A rocket made almost entirely of 3D-printed parts made its launch debut Wednesday night, lifting off amid fanfare but failing three minutes into flight — far short of orbit.

There was nothing aboard Relativity Space’s test flight except for the company’s first metal 3D print made six years ago. It was the third launch attempt from what once was a missile site. Relativity Space came within a half-second of blasting off earlier this month, with the rocket’s engines igniting before abruptly shutting down.
