One (future) Starship's payload bay alone has more volume than the ISS—that's not counting the fuel tank volume that shares a common bulkhead. The payload bay takes up just ~1/3rd of the spacecraft length.
- "The Starship spacecraft is 50.3 m (165 ft) tall and 9 m (30 ft) in diameter. It uses 6 Raptor engines, three of which are optimized for use in vacuum.[6][22] The engines produce 14,700 kN (3,300,000 lbf) of thrust.[17] The vehicle's payload bay is planned to measure 17 m (56 ft) tall and 8 m (26 ft) in diameter with an internal volume of 1,000 m3 (35,000 cu ft); slightly larger than the ISS's pressurized volume.[23]"

- WWLink 3y agoI remember a common talking point for space shuttle haters (aka people who use the word "boondoggle" way too damn much) was that it's a truck and we don't need a space truck. If it was a truck what is starship?
- DiggyJohnson 3y agoA much much much cheaper truck.
- perihelions 3y agoIt's a very good point! From one perspective, you can view Starship as a challenge that SpaceX can implement the STS (Shuttle) concept much better than the original STS itself. (And doing so, become cheap enough to create a high-volume orbital launch market). It's correct to be skeptical, even with SpaceX' track record. (Was it pg or whoever on HN who kept railing on that point about YC startups, that the implementation is everything—high-level ideas and concepts come cheap). If Starship's proven a lot of things, there's still major show-stopping uncertainties remaining, like if they can execute well on the reentry heat-shield tiles. That was overwhelmingly difficult for STS. I'm not knowledgeable enough to guess if SpaceX is on a promising track with those or not—I'm looking forward to finding out what happens! (Here's an open-ended question: if the modern SpaceX were asked to build a reusable spacecraft with (broadly) the same design choices as STS, would the outcome be closer to the dismal failure of the original, or to the success of Falcon 9? That is to say: how much of SpaceX' success do they owe to smart high-level design choices, vs. effective low-level execution?)
- Yossarrian22 3y agoBy same design choices do you mean that it is mandated that an essentially reusable cargo truck be mounted to the side(s) of booster(s)/tank? Because that was the shuttle's damning sin. Besides the collapse of the USSR there's a reason the Buran wasn't further pursued, and commercial space hasn't pursued a similar form factor.
- somenameforme 3y agoIt's using the same engine as the Space Shuttle (literally - it's using refurbished engines from the Space Shuttle [1]), exact same solid rock boosters with all their flaws, and so on. One difference from the Shuttle is that the SLS doesn't even have a pretext of reuse. It's a single-use only rocket. One other big difference is that it's also obsolete before it's even complete. It can lift about 50% more than a Falcon Heavy for what will be orders of magnitude greater cost, to say nothing of comparisons to Starship. So there's no viable use case for it to ever actually be used, except for corruption. So it will be used, but it's just been a monumental waste of money that could have instead been directed towards meaningful progress in space. The entire Apollo program which spanned 11 years and started from zero, only cost $180 billion in total, inflation adjusted - less than $18 billion a year. NASA's current budget is $26 billion per year. [1] - https://en.wikipedia.org/wiki/Space_Launch_System#Core_stage https://en.wikipedia.org/wiki/Space_Launch_System#Core_stage
- cryptonector 3y ago> if the modern SpaceX were asked to build a reusable spacecraft with (broadly) the same design choices as STS, [...] That depends on which design choices should stay the same. The boosters and the main tank were bad design choices that made reuse unattainable. With Falcon 9's and Starships reusability lessons in mind perhaps one could make the boosters just part of the main tank, all methalox burning, and have the main tank land itself. With the booster and main tank design choices disposed of, the remaining major design choice would be that the shuttle had to be a space plane that could land like a plane. That seems like a tremendous waste of weight which would keep the new program from being broadly successful at being cheap, though it might not be fatal I suppose. But at this point Falcon 9 has a better reliability record including landings since they figured out landings than the shuttle did altogether since the STS became "mature".
- pfdietz 3y agoThe Space Shuttle wasn't a boondoggle because it was a truck; it was a boondoggle because it was an incredibly expensive truck. It failed utterly at the ostensible and valid reasons it was constructed, to make access to space cheap and routine.
- dylan604 3y agoWhere the shuttle led, cyber truck has followed.
- justinclift 3y agoThe cyber truck is just a follower. The Roadster got there first: https://where-is-tesla-roadster.space/live https://where-is-tesla-roadster.space/live
- namaria 3y agoThe reason it was expensive was the military specs (be able to land back home after one orbit etc). The goal of the space shuttle was also to help drive USSR to bankruptcy and it delivered. The soviet counterpart was a huge resource drain and did exactly nothing.
- pfdietz 3y agoThe reason for military specs was the case for the Shuttle was so marginal it required fantastical projections of launch rates and launch market to make the numbers work (and all that was far too optimistic, as subsequence experience showed). This required all government launch customers to use it. NASA desperately needed the military on board; the military didn't want it and had to be strong armed into supporting it. That military requirements were then added has to be the responsibility of NASA (or of NASA's political masters) for forcing the military to be a customer.
- akira2501 3y agoIt was designed to put classified satellites in orbit and possibly go recover them. In the long run it somewhat paid off for the repair Hubble missions. It was also a pretty cool truck. It generated 21kW of power, using Hydrogen/Oxygen fuel cells, and captured the output water for use on missions. During most of it's life it had to send the excess water overboard, but when it came to ISS, they started bagging it up and transferring it to the station. The power itself, the payload bay, the payload manipulation arm made this a pretty nice platform to build ISS with. Which was a natural consequence of the shuttle not being good for much else than building space stations and recovering spy satellites before the Russians did. In terms of a natural step in our evolution towards a space faring society it was an incredible vehicle and it inspired the imagination of everyone who watched it fly.
- rkagerer 3y agoA freighter?
- 1oooqooq 3y agoironically those people love the agencies who forced nasa to make the shuttle extremely expensive, because the secondary purpose was to bankrupt the Russians, who were beating them in all aspects of the space race. shuttle delivered even on that goal. akira2501 comment explain how it was awesome in the number one goal.
