>>16082861
you have read the words too, not just be dazzled by the pretty colors

reminder that ift3 failed. no mid flight relight which means no orbital flights from here on out until they actually do a mid flight relight, 4 months from now at the earliest. If the booster made it all the way to splashdown or soemthing i would have said it was an overall sucess. but really this flight only made marginal unimportant gains over flight 2.

true, I would argue this was a complete failure, not even a partial failure
every single objective starship needs to to be viable for Artemis has failed so far,

>>16082885
we arent even talking about recovery, we are talking about the basic objectives of a disposable launch vehicle such as getting to orbit and out of orbit in a controlled way, and maintaining control through flight.

>>16082895
disposable launch vehicles need to get out of orbit in a controlled way? this is news to me

>>16082895
If we treat Starship as an expendable rocket then IFT-3 was a almost a full success. Controlled deorbit is optional.

>>16082901
how would it deploy the payload optimally if it was spinning out of control?
>>16082899
unless you are chinks then yes, you typically deorbit used stages

So has there been any new footage?
Like the booster coming down?

>>16082912
Deploying a payload was not a goal.

Ding ding ding. Chortler

>>16082776

>Starship will colonize ma-
No.
The real colonization is building modular spacecrafts using on-orbit assembly and the use of the 'Cislunar Highway', a term coined by ULA CEO Tory Bruno, where ACES/Centaur depots are positioned strategically in deep space for refueling operations.

>>16082981
I won't say it's impossible but it does sound ambitious. Pad 1 has been "technically done" for months and it hasn't seen any launches yet.

>>16082983
If they were using a new system instead of a tried and tested approach, that makes it more understandable that they developed problems and less of a problem that it failed.

The main thing IFT3 showed was that hot-staging works just great.
Lots of people thought it wouldn't, and demonstrating that it does work is plenty for one test.

>>16082776
I can't wait to see this launching brilliant pebbles.

>>16083005
We also saw the boostback burn work without exploding the booster and got turbo kino Starlink video of Starship in space.

>>16083000
The CZ-8 production rate that would necessitate pad 1 might not have been achieved yet. CZ-8 can launch from the 2016 pad, and that pad is nowhere near full utilization. The next CZ-8 launch in a few days will be just the third.

>>16082991
judeo-herpetological buzzwords

>>16082935
to prove that they can get to probit and deploy a payload safely they need to demosntrate that, regardless of if they are carrying a payload.

>>16082983
Yeah guess what: he is not an engineer

>>16083039
Getting to orbit wasn't a problem, only attitude control that will most likely be fixed beforet the next flight.

>>16083025
better?

Starlink sats are now 60% of all satellites in orbit

>>16082991
The one real issue with Tory's bullshit ACES plans is that he never explains just how he's going to get all of that hydrogen to all of those deep space depots. Vulcan isn't a big rocket. It can't lift that much to high energy trajectories.

>>16083059
Lunar/NEA ice mining was the plan.

https://spacenews.com/peregrine-payloads-returned-useful-data-despite-no-lunar-landing/
>Griffin and VIPER were set to launch as soon as this November, but Kearns, speaking at a Planetary Science Advisory Committee meeting March 5, said that will likely slip. “It is extremely unlikely they will fly before the end of this year,” he said, because of not just the Peregrine investigation but also other work to prepare the rover and lander for launch. He said NASA would wait to set a new date until after the Peregrine investigation is complete.

>>16083066
And that's an even bigger job than lifting hundreds of tons of hydrogen to a lunar orbit. This is the problem. The cislunar highway is a nonstarter because the things you need to make it possible also make it completely unnecessary.

>>16083122
It's what the Chinese call it. The name of the launch site is 海南商业航天发射场, Hainan Commercial Space Launch Site, often abbreviated as 海商. The word 商业 means commerce/commercial. 海商 is a distinct launch site from 文昌航天发射场, Wenchang Space Launch Site, which is the old launch site just to the north with two pads that were completed in 2016.

The company that runs 海商 is called 海南国际商业航天发射有限公司, Hainan International Commercial Aerospace Launch Limited Company (HICAL), which is a joint venture between Hainan province and three SOEs.

A key difference with 海商 is that HICAL is building a universal pad (no. 2) which is designed to allow any propellant combination and be compatible with any tank diameter between 3.35m and 5m diameter, thus being compatible with 19 different rockets from 10 different companies. This pad will be made available for any launch company to use, unlike the other state-run liquid pads, which are reserved for CASC. HICAL will also have two solid pads.

This is something I want to see in action. The only other launch complexes I can think of that accommodated multiple kinds of rocket had vehicles from the same specific family; SLC-17 for Delta II and Delta III, LC-39 for Saturns or Falcons, etc.

What?

Lets be honest /sfg/, we all know in the bottom of our heart that the moon landings were kinda... Fake right? I mean how can you explain we did it 6 times 50 years ago and now days we cant cause "space is le difficult". During this time we landed two huge rovers on mars, plobes to jupiter and pluton, James webb, hubble, ISS etc but now NASA cant replicate something they did so many years ago? "Bu but they got a way bigger budget back then" ok I kinda get it but its not supposed to be cheaper and easier now with all technology and experience we got today? And dont forget NASA already spent 30 billions dollars on Artemis and all we had was a uncrew capsule flyby (not even a orbit like apollo 8)

After all I think if we use logic... Apollo missions were a complete fraud and we believed it...

>>16083320

Because NASA is no longer filled with spirited young men of dubious national origin in a race against commies. It's a pile of diversity hires whose sole job is to redirect money to the maximum number of congressional districts without normies realizing how badly they're being fleeced.

If you're thinking "so all that money went to waste with nothing to show for it?" consider how many trillions have been spent on aid for Africa.

>>16083680
May 4, Starship RCS will get fixed, they will try and succeed with in space engine burn and Starship will enter the atmosphere without spinning in the correct attitude, probably still burn up

Reusables are still a meme and practically every space agency on Earth recognize that.

Reusables are stupid for the vast majority of circumstances. They're even stupider considering how few heavy payloads are being lifted.

>>16083934
The whole point of reusability falls apart when you realize that there aren't nearly enough fucking payloads to justify it you dumb smooth brained tard. That's why they came up with Starlink because they would get single digit launches per year with the normal market.

But then your tooling and infrastructure just sits idly by while a single rocket does an entire year's worth of launches. You SpaceX brainlets don't seem to understand that rockets are trucks to deliver payloads. That is their only function. You don't build a fleet of trucks for a handful of payloads.

Get it now? If you don't like there are plenty of circlejerks on Reddit waiting for you.


In fact, there are actually fewer customers for satellites compared to 10 years ago so there's even less incentive for a reusable rocket unless you're doing constellations.

Rocket companies launching their own payloads doesn't mean anything.

>>16083905
post the color version

There are fewer customers today than there were 10 years ago. Hence why rocket companies have shifted to launching their own payloads. I invite you to point at any payloads that are only in space right now specifically because SpaceX was marginally cheaper in one of the cheapest parts of spaceflight.

Even then, Vulcan, a brand expendable (the horror) already has 70 launches sold and earned ULA more launches from the Space Force than SpaceX while being cheaper than the F9.


You can jerk off to your fantasies all you want, but you can't get around 70+ launches sold. Cope.
Being reusable compromises it's ability to missions outside of LEO.

The conventional market is still a bit too small to take advantage of something like Falcon 9. The "If you build it, they will come" principle is still largely correct, but they're not going to show up anywhere near quick enough to match SpaceX's goals or pace.

Cubesats can move a lot quicker than everyone else because they're built with the cheapest grade of parts and aren't concerned with maximizing satellite lifespan. Most full size satellites are still using buses built by Boeing or Airbus. I'm actually a bit surprised that SpaceX didn't move harder to get into that market segment.

>>16083992
Rocket Lab is jumping on that train and SpaceX decided that their engineering resources would be better spent on internal projects like Starlink instead of trying to make something universally applicable

For better or for worse. Maybe there's some sort of way out if you can create a causal disconnect between what you want to go FTL and the rest of the universe, but without that, there doesn't seem to be any way of doing it. And I don't think there's any path to inducing casual disconnect through quantum electrodynamics.

There will be a blood bath once starship gets rolling. All the other companies will drop like flies.

Also SpaceX confirmed comitting genocidal bloodbath

>>16084246
ULA's advocates remain convinced that reusability isn't all it's cracked up to be and Vulcan will have a strong long term outlook on its own merits. It's going to be interesting to see how it shakes out.

>>16084246
Any company (aside from whoever the DoD allows to be Spacex's Designated Competitor) that's currently dedicated to launch services has its days numbered. Starship will lay waste to the launch market.
Existing companies should be pivoting to payloads if they want to live.

>>16084256
good. That's how it should be. Launch services should simply be a solved problem and everyone should be focusing on infrastructure, science, and destinations.

>>16084256
Actually I think Stoke has a good chance at living, there will still definetly be space for other fully reusable launch vehicles. They plan to take the small launch sector I think so if some companies just want to pay to launch up one smaller thing and not have to wait for a Transport rideshare mission OR instead pay for a full Starship then there is that method. And its not like thats a tiny share of the market, cubesats can be a good business especially since there will be more private companies looking to send them up once launch prices are significantly reduced. Other than that though, yeah basically everything that isnt fully reusable is dead in the water unless they manage to get something bigger than Sea Dragon for expendable launches to send up entire fucking space stations in one go to Jupiter or Mars. Only then would I see some extremely niche use case for expendable rockets.

>>16084269
Also on the idea of fully reusable being cheaper in some ways, for non US-based companies there is still the matter of transport between countries, continents, etc. that SpaceX can't do anything about. Coupled with the fact that these are delicate payloads they would probably need to pay a premium to these other shipping methods. This leaves space for competitors native to other countries or continents to take up that 'reusable rocket' spot in the economy that would be cheaper than shipping if half way across the globe. Now this is all thinking that SpaceX doesn't somehow expand to other countries but considering they work with the DoD and USSF on some top secret shit that they would probably not want other countries outside of their jurisdiction getting ahold of its fairly possible for this to happen.

>>16084281
Somewhat retarded, this is saying a colony ship would be a Starship based model. Equivalent to saying in the early 1900s that modern semi-trucks crossing the country would be based off of the Ford Model T. Like they're the same type of transport vehicle but theyre just not built for that.

>>16084209
if for you, the traveler, only 10 hours pass while you travel 10 light years, isn't that, effectively, traveling faster than light? Even if to an outside observer it took you 100 years to travel that 10 light years. If time can be slowed for the traveler then faster than light travel will be possible (for the traveler).

>>16084288
don't be so pedantic

>>16084296
In this hypothetical case, it's like traveling through another dimension, where the intermediate space does not exist.

>>16084297
It's not pedantic it's just logical. I fucking adore Starship and I think it's going to do exactly what the Model T did to the auto industry but I don't think it's going to be a colony ship.

>>16084321
Making the journey at 10% the speed of light rather than 99% saves you from being zapped by everything upshifting at you, and allows a drastic reduction in the energy need to start/stop (not to mention the extreme dangers inherent to the destination from accidental relativistic traveler impacts).Therefore efforts should be made to slow the passage of time for the traveler rather than to increase the speed of the traveler. A traveler who experiences 10 hours pass while making his uneventful 10 light year trip (in 100 years) is a happy traveler.

but can you insert it into a circular orbit in one impulse?

>>16084502
>extra maneuver
you're over thinking it and it's a theoretical possibility not like you're actually going to aim precisely enough to achieve it, just fucking accept it as something that can happen on a low gravity sphere with no atmosphere and get over it already

no conventional gun can achieve lunar orbital velocity
>>16084555

>>16084559
are you a fucking retard? of course you can achieve a circular orbit by firing a projectile horizontally on a sphere with no atmosphere as long as terrain doesn't get in the way at any point along its path

>>16084561
>no conventional gun can achieve lunar orbital velocity

Wrong. No conventional sidearm fired from anywhere on the moon is capable of orbital velocity, and even if the moon was perfect sphere with no obstacles. it would follow a ballistic trajectory

yes, that's what an orbit is, an object free falling in vacuum, always missing the ground.

orbital velocity around the moon is 1.68 km/s

>>16084605
they arent able to carry a payload to orbit because they havent demonstrated relight capability after a coast in space. that whe whole reason why all these flights have been suborbital and will continue to be until they do that

>>16084615
Sorry dude, not an orbit. Bad information you're spreading

>>16084502
if you're:
A. on a mountain
and
B. shooting at just above orbital speed
you can absolutely hit in your own vicinity with a bullet
fortunately B is not true for most firearms, I think you can hit that speed with saboted smoothbore tank cannons though

>>16084634
You can't kill astronauts when you don't launch with any, concern troll-kun.

>>16084649
luckily pic related (5500 fps is 1.68 km/s) so it's definitely possible, but you need to use a saboted smoothbore round, which will be difficult to stabilize without an atmosphere
