AMAZING!!
HTF can people be so clever to work out how to nail the return to the launch tower basically to perfection?
I am in absolute awe .... And a little disappointed there was no massive RUD which I thought was pretty much guaranteed!
I feel conflicted over SpaceX. They do some incredible science and engineering but are owned and led by a grade A ****er.
I can’t believe That just happened, absolutely amazing.
Very impressive.
Missed it live but I'll remember that I was driving home from work on the m66 when it happened for the rest of my life. Winky eye emoji.
Hopefully the ship has an equally impressive landing.

Yeah, AI-generated video is pretty impressive sometimes! 😉

I ignore the latter and just focus on the former!!
End of the day he has the basic idea but he's not the one doing the physics, maths and coding.
its not that impressive. Gerry Anderson was doing it in the '60s
Clever stuff, just saw it !
It’s brilliant. The Saturn 5 rockets cost the equivalent of 2.2billion dollars per launch. The cost was one of the main reasons, along with the dodgy decisions leading to fatalities, the US cut back on funding space exploration and why we haven’t been back to the moon since 1972. If they can make it more affordable then it’s got to help the space exploration cause.
Roll on moonbase alpha and a mission to Mars. If I live to see it.

I dont think its just Musk. Ego driven and they achieve a lot, and you'll probably find most at that level are complete 4r5eholes. I think narcissism probably comes with the territory.
The science, engineering and ambition is incredible! I do agree though, Elon = weapons grade ?
It's good stuff, but thrust vector control has been moving in leaps and bounds over the past generation due to computing advances, it's opening up a lot of design improvements across many fields.
I was expecting a near-failure, and tbh thought that was what we were getting right up til the last moments, really impressed. I love how <unconvincing> it is. Like, it's real but it looks fake as ****, just like the falcon landings (and especialyl the twinned ones)
I wonder what the environmental consequences are?
There was a massive cloud of crap hanging around in the air after it took off which it then added to on the way back down, plus it was venting something after it landed
Are they planning on landing crewed rockets like this, or is it 'just' the boosters? Previous results and the margin for error/time from detecting a problem to a massive explosion don't seem compatible with having people balanced on the top. But maybe it's no worse than the launch once they've tested enough? I suppose you have to do something like that for mars/moon missions or no one's getting back to orbit, but they at least have lower gravity.
The cost was one of the main reasons, along with the dodgy decisions leading to fatalities, the US cut back on funding space exploration and why we haven’t been back to the moon since 1972.
We haven't been back to the moon because the entire reason for going there in the first place was political. In short, there's no point.
What fatalities are you referring to? Apollo 1?
My main problem with musk is that the spacemen look like they are going to a fancy dress party and have had to use a pair of wellies for space boots.
Spacemen should look ****ing epic.

It burns methane if that's any help.
Apparently it's environmental impact is miniscule compared to other modes of transport.... Such as shipping and cruise liners.
Dunno.
I think Muskrat is allowed to play with toy rockets and look at all the whizzy equipment and gloat about his company, while being kept as far away from the real things that might fall down, go boom as is humanly possible!
The ability to actually catch a descending rocket stage, with what is effectively a giant pair of kitchen tongs is astonishing, certainly not something I ever expected to see happen. Synchronised rocket stages landing on a floating platform, hmm, maybe not beyond the realm of possibility, but using giant tweezers, nope!
It is impressive, but the rocket had pretty much landed anyway* and the tongs just seemed to kind grap/guide it that last bit.
*Which is a hell of a feat in itself, it was pretty much just hovering in the right place before it was 'grabbed'.
But also it's Musk... the guy is a proper ****ing loony, and not in a good way.

Free MemberI wonder what the environmental consequences are?
I mean, not great, they burn a load of hydrocarbons and occasionally blow one up. And the local damage around boca chica has been pretty bad (it is barking mad that they were allowed to build there tbf). In particular some of the emissions are high atmosphere which is believed to have a more significant and lasting effect.
But in the grand scheme of things, the commercial aviation industry emits more in a few hours than all our space launches do in a year. I hereby donate my reduced air travel emissions since 2019 to cool rockets.
(stuff like this test should actively reduce the environmental impact, we can reuse more stuff rather than burning it up or throwing it in the sea... On the other hand of course is there's a cost saving too so we'll probably fly more launches. Starship if it realises even half its potential basically makes it possible to launch stuff that we just wouldn't today so that'll be impactful. On the other, third hand, it will also enable us to launch more stuff in a single launch. Complicated. Without a doubt our space emissions are going up but there's tweaking in there)
I wonder how much money is saved by having these reusable rockets. Probably millions but it surely must be peanuts compared to the total cost of R&D and all the non reusable elements.
Cougar2 I was referring to the space shuttle Challenger and the dodgy decision to launch in cold conditions with a known issue with the o rings on the solid boosters. NASA had a Boeing moment and although more shuttle missions were flown the funding was gradually reduced.
The political will to beat the commies fizzled out in 1972 with Apollo 17 but the scientific will still remains. Now we are in the private/ public era with Space X and others at least things are moving again. It’s amazing that man hasn’t travelled out of earth orbit since 1972. What happened to our George Malllory spirit of adventure.

These are properly reusable rather than the pretend resuable Shuttle SRBs. Many active boosters have now done over 20 missions each. Seems like production/service will be making an increasing impact against the R&D figures

What happened to our George Malllory spirit of adventure.
We've ticked off the moon (sort of), and after that choices become rather limited.
The R&D has already been spent, if the plan is to do this activity a lot, then reusing components is always good to do, but safety then comes into it with appropriate lifing of these components.
The SpaceX development reminds me a bit of the Harrier vs the F35B, both had Thrust Vector Control, but the harrier was mandrolic, compared to F35, which has 21st century technology running the TVC and monitoring everything, so is amazingly precise.
Nothing special. Autopark unit, duct tape and soldering is all. Reverse parallel parking has been a feature of Tesla cars for a while 🙂
The US X-37B automated space plane is on its seventh flight, its elliptical orbit dips into the earth's atmosphere to either burn up some unwanted modules or act as a brake to change its orbit. It does that without using extra fuel, which is handy when you launched it last year and need to watch your mpg 🙂
Landing means you need a landing system, this is just reinforced gridfins for capture. In essence, you’ve move the landing system to the toward which saves weight. Every kg of weight launched needs around 150kg of fuel to LEO.
Cost savings for reusability are only a small part of it. ASL believe that the cost savings vs disposal are 20-30% max as the reusable rocket is both more expensive and heavier and requires rework. Launch cadence is the real benefit. You can simply do more and it’s the cadence, not the cost which hammers your competitors.
Apparently it’s environmental impact is miniscule compared to other modes of transport…. Such as shipping and cruise liners.
Dunno.
Are they comparing 1,2 or 3 launches with the hundreds of thousands of flights made every year?
i refuse to beluieve that thing is more fuel economical than a passenger jet. isnt methane the worst greenhouse gas? i had pressumed it would be burning something like hydrogen.
and without wanting to be a naysayer, as its undoubtebly incredible, i wonder what the energy cost is to have the fuel to park it like that, and the fuel to take that extra fuel up, vs an unpowered splashdown, and recovery with a boat.

Is the data available? The first methane-fuelled rocket to make earth orbit did so barely a year ago. Methane's bonus is that it leaves a cleaner engine ready for re-use

Methane is worse than CO2 (but far from the strongest greenhouse gas) but they will be aiming to burn it rather than release it unburned into the atmosphere. In which case you end up with CO2 and water.
(Water accounts for about 50% of the greenhouse effect - but its cycle is not really comparable to CO2, Methane etc).
You don't need Thunderbirds or Jame Bond villains. Proving that nothing is really new or innovative, The US Navy were looking at vertical capture back in the 1950's. Must be a bunch easier with computers doing all the thinking these days
Landing means you need a landing system, this is just reinforced gridfins for capture.
It lands on itty-bitty little feet that stick out from the side, not the grid fins.
an unpowered splashdown, and recovery with a boat.
AFAIK that was a major cost with the SRBs, dropping a red hot rocket full of all sorts of corroding materials, electronics, hydraulics etc from several miles up into a huge salty sea, letting it sink and then recover, requires a *massive* clean up and refurbishment.
Not that the SpaceX refurbs are cheap. Just bugger all thermal shock and salt damage to deal with.
Superheavy is still supersonic when the engines relight. An unpowered 'splashdown' would result in thousands of little bits. alternatively, a HUGE set of parachutes with all the weight that entails.
But, what they really want is cadence, launch, land, fuel up, launch, land, and repeat. That's never going to happen if it lands in the sea.
Once you get over how crazy this is, it makes a lot of sense.
Musks mars mission just reminds me of the "Golgafrinchan Ark Fleet Ship B" from Hitch Hikers. Will Mars just end up as some kind of MAGA colony??
Quite an incredible concept. I believe Musk came up with the idea while lying in bed one night ...
Will Mars just end up as some kind of MAGA colony??
I love that idea! Pack the rockets with MAGAs, Flerfs, anti-vaxxers, covid deniers etc and just punt them up to Mars. Or better, Venus. Cheers guys, good luck! Don’t let the door smack you on the arse… etc etc

In 50 years time, Musk will be used in the same breath as Einstein or Newton
It looks to me like it’s on the primary connective structure to the grid fins, which would make sense as they have some of the major structural loads during descent and control until the engines take the strain.
Been all over Twitter today- apparently it’s just caught on two hooks on the booster! The arms don’t grab it at all!! [insert shocked face]
https://twitter.com/seventhmeal/status/1845610000179159524?s=12&t=EQoHg-RGok071Fjc15ZHKw
I can’t see that as not on Twitter, but are the catch pins still attached to the corrugated bit that also holds the grid fins? Or are they further down? If it’s on the corrugated bit, that’s the staging ring which is heavily reinforced for booster sep. if it’s further down, that’ll mean a unique price of structure or something attached to the tank support, but I think the tank support is also part of the staging ring as Starship’s engines don’t protrude from the fairing. The Tower is still doing the catch either way, but it’d be interesting to know if there’re a few catch pins (to allow it to rotate axially and still be caught) or if it’s just two and they’re that precise. If it’s the latter, that’s very impressive.
AFAIK there's just two catch pins and they're defo for the chopsticks and not part of the staging ring (which will not be part of future builds anyway).
It certainly isn't supposed to land on the grid fins now.
I can’t see that as not on Twitter,
You can. Just click on it. I'm not on Twitter/X and I can.
It invites you to log in or register on the site - but you can see the photos.
The thing that struck most was just how much they were able to manoeuvre the booster when it had already descended to almost tower level. I'd pictured it coming in hot from immediately above the tower but the trajectory they used allows an abort up until the last few seconds. I just didn't envisage the booster going sideways.
As regards the two pins, I guess this means that they can rotate the booster along it's long axis too..

Ford or Edison maybe, he's an industrialist with a more than passing interest in some subjects. As one software engineer noted;
"I know nothing about rockets, so when Musk talks about them, I assume he knows what he's talking about, however I do know coding, and in relation to Twitter's code, I do know what I talking about, and Musk talks the most absolute total shite I've ever heard"

Odd - I get this. Not sure if it's because I'm on a computer not my phone or something.
Did YouTube just ban the space x channel during the latest live stream due to Elon pushing crypto?
No chopsticks this time....went for a water landing. Be interesting to hear why
Did YouTube just ban the space x channel during the latest live stream due to Elon pushing crypto?
Ah no. It was a site showing a stream of the launch and then they edited in some video of Elon doing a speech with the audio changed so people would send crypto to a certain site and he would then send back double the money. It was very well done indeed (although of course you would have been mad not to ask the question why)
Tower called go for catch so I guess a booster issue?
That's what it looked like
Although it seems to still do an on target soft landing anyway.
