| Starship is, essentially, Space Shuttle done right: fully reusable booster without solid boosters (avoids Challenger disaster) and orbiter stacked on top instead of on the side (avoid Columbia disaster). The original designs for the Space Shuttle had the booster (with wings!) return to the launch site, but the cost for two new crewed vehicles was too large, so they scaled it back to the compromised version. Even more revolutionary, compared to Shuttle, Starship is built on an assembly line. They can build a booster ever 4 weeks and a ship every 2 weeks. The future we were promised in the 1970s is about to become real. |

| Space shuttle was a reliable recovery vehicle too. I see a need for maintenance crews and large payload recovery in the future. Starship doesn't seem like the tool for that, and no tool is in development for it TMK? |
| |
| ▲ | nickff 10 minutes ago | parent | next [-] | | Recovery never paid dividends for Shuttle, due to satellites' degradation in orbit, and SPCX seems to have driven the industry even further from 'exquisite systems'. I love the idea of in-orbit servicing, but I am not sure it will ever work for unmanned objects. | | |
| ▲ | Rapzid 2 minutes ago | parent [-] | | The economics and use cases have and are evolving. I don't see this as "space shuttle done right" as a vehicle or "program" without the ability to carry out maintenance and recovery missions. As expensive as it was, for various reasons, it was actually used for those missions. For example I don't think "space data centers" are going to work I'd the upgrade path for the hardware is vaporize is all and replace it vs recover and recycle/resell. |

| ▲ | colechristensen 17 minutes ago | parent | prev [-] | | no reason you couldn't make a starship with a cargo bay for recovery, it would just cost a considerable amount of payload mass |

| The Space Shuttle took 2 people into orbit on its first launch and returned them safely to earth. On the first attempt. On the first test of any of the hardware into space. In 1981. Starship did not and has not done that and until it does I will continue to hold reservations. I do not see this Starship and its mission profile ever being a human-rated system in this incarnation, ever. A really cheap way to launch mass into LEO? Sure, I'll give it that. |

| ▲ | nsoonhui 35 minutes ago | parent | next [-] | | > I do not see this Starship and its mission profile ever being a human-rated system in this incarnation, ever. May I know why ? And if the feat was done by NASA or China, would you change your conclusion? | | |
| ▲ | mk_stjames 19 minutes ago | parent | next [-] | | It would not change my conclusion at all. If you asked me if I wanted to return to earth on something that glides like a plane and lands on a runway with no propulsion... or a pressure vessel that needs it's engines to work perfectly to get you back to a single spot at the pad, within a few meters, to be 'caught', and if that doesn't happen, you hit the ground vertically and explode... I know which one I'm taking. Yes I know the shuttle had no 'go-around' as a glider. But wings and wheels and a big runway in the desert.... versus the insane acrobatics of Starship... We haven't seen how Starship would deal with crosswinds in the atmosphere being predicted wrong. What happens when it knows it is off course on the way down and can't make it back to the pad? If there where people onboard? I assume there would be a contingency where it just vents fuel and hits the ground and hopes to act as a crush-can at terminal velocity but I don't know how people survive that. By comparison, ditching the shuttle like a plane with an engine-out failure seems easy by comparison. I am not demeaning the amazing achievement of the Starship and its booster and this ability to catch it and reuse it. I think that is indeed an amazing achievement that should be celebrated. But I don't see this as being a thing to put people on that can somehow be intrinsically safer than the Shuttle, just yet. These are just my basic opinions, I think they are opinions with some merit, and I don't feel that deserves downvotes. | | |
| ▲ | emkoemko 11 minutes ago | parent [-] | | that's not going to happen, Artemis is using Orion with parachutes to land in the ocean |
| |
| ▲ | echoangle 26 minutes ago | parent | prev | next [-] | | The system architecture seems to be more fragile than simple capsules with parachutes or even the shuttle (which was already pretty dangerous). There’s no parachute, if you don’t hit the tower during landing you’re in a lot of trouble (unless they can soft-land the ship without the tower and without the bottom exploding?). | | |
| ▲ | xixixao 20 minutes ago | parent [-] | | “the system is more complicated” is not a good argument for it never working. A passenger airliner is vastly more complicated than a parachute, yet both work. (You’re also in a lot of trouble if you don’t hit the runway in an airliner) | | |
| ▲ | echoangle 14 minutes ago | parent [-] | | The problem isn’t “it’s more complicated” but more “if something goes wrong there’s not a lot you can do”. There’s basically no redundancy and a lot of single points of failure. Having two sets of Parachutes is a lot harder to screw up than a powered landing. With a normal capsule, you have multiple fuel tanks and redundant RCS thrusters so you’ll practically always be able to deorbit and land (since you also have redundant parachutes). If starship has a fuel leak, how are you going to land, even if you’re able to deorbit? |

| ▲ | Retric 25 minutes ago | parent | prev [-] | | Starship’s been in development for over two decades and the design keeps being changed and failing. Soyuz has a very impressive record, Starship has been horrifically mismanaged by comparison. The falcon heavy flew 14 times and SpaceX is all in on a heavy launch vehicle because what? Even if they hit every target perfectly from now on it was a wasteful project. | | |
| ▲ | xixixao 13 minutes ago | parent | next [-] | | The design changing and the development _failing to meet its stated deadlines_ is not a good argument for the system never working. Especially given we know the deadlines were unrealistic to begin with, yet significant milestones have been achieved in (deadline-ignoring) impressive time frame - like landing a second stage rocket from orbit within 8 years of development (by a private company, not a national effort). | |
| ▲ | bluescrn 10 minutes ago | parent | prev [-] | | Falcon 9 had numerous landing failures early on. They're averaging over 2 successful launches+landings per week now, and it's so routine that nobody cares. |
|
| |
| ▲ | GMoromisato 26 minutes ago | parent | prev | next [-] | | Huh? Space shuttle killed 14 astronauts. It was a flawed design from the beginning and never delivered on its original promise. Starship has its own design trade-offs, as any engineered object does, but it has the benefit of 50 years of technological development since Shuttle. I'm not as certain as you about whether or not Starship will ever be human rated. But if successful, it will be launching a couple of hundred times per year. Talk to me in five years and we'll see where we are then. | | |
| ▲ | cucumber3732842 8 minutes ago | parent [-] | | I don't think it makes sense to make starship human rated. They'd likely give up too much. Probably better to have a different cheaper rocket for the people. Like you don't build a barge to ferry standards, it would defeat the point of the barge. |
| |
| ▲ | Quarrelsome 21 minutes ago | parent | prev | next [-] | | isn't the whole "we put a human into space" symbolic anyway? There's no air up there. If we had a full supply chain of robots that brought us back regolith from the moon wouldn't that be more useful than being able to send a person up there? | | |
| ▲ | colechristensen 10 minutes ago | parent [-] | | nah humans going is the point. the science is interesting but not of that tremendous value. we don't view archaeology as the highest human endeavor do we? |
| |
| ▲ | xixixao 23 minutes ago | parent | prev [-] | | How is incremental development and testing related to human-rated flight? As is, your comment has a bold claim backed by seemingly unrelated fact. | | |
| ▲ | mk_stjames 2 minutes ago | parent [-] | | My comment was in reply to the parent comment saying "Starship is, essentially, Space Shuttle done right"
, and my claim is that this is not the case, that comparing Starship to the Space Shuttle is a category error, in that I don't see Starship actually being replacement for the Shuttle as a human-transport vehicle, and thus it cannot be considered 'Space Shuttle done right'. |

Note that they are also scaling up production in a big way, because they want to launch weekly soon, and then daily. Not sure if we will get to the latter anytime soon but I'm also not going to bet against Elon. |
| |
| ▲ | bluescrn 8 minutes ago | parent [-] | | When Falcon 9 was making its early landing attempts, I'm sure people would have struggled to believe that they'd soon be doing over 120 launches+landings per year with very few mishaps. |

| "fully reusable" is highly aspirational. They have barely reflown a handful of tiles, and have not reflown any engines. Essentially, the two things you'd expect to break will probably still break. |

| ▲ | pokstad 16 minutes ago | parent | next [-] | | Landing the damn thing (and almost landing the booster) seems to point in the general direction of full reusability. | |
