  1. Do you not remember the first few modules delivered to space for the ISS ? These were just the bare minimum. None of these were berthed - they were all docked. Also NASA is getting used to having to send cargo with only IDSS/IDA as the access, given one of the CRS vehicles.
  2. What, autonomous ? We're still quite a way from that. Yeah, they'll just use IDSS/IDA to connect all the modules.
  3. In those years they have mostly flying boats still... If something goes bad you can always land anywhere. Maybe more like airship safety than airplane safety in 1935. (Hindenburg was 1937)
  4. Well you can't do it for a new station without Shuttle, that's what I was saying. CBM will be limited to the ISS.
  5. And CBMs aren't hitting each other... There's a reason we'll never see CBMs again after Shuttle due to the loss of the arms (although berthing is still possible for ISS but I question you can do it entirely unmanned). There's actually one APAS being used to connect the ROS with USOS, and I can't see how the other two PMAs would be of a different design. However I'll say that the currently used IDSS/IDA on the crew capsule itself are definitely not the heavy type. Not sure about the APAS to IDA/IDSS adapters itself, there's a chance it's not the heavy type as well. But yeah in a way we alr
  6. Where do you think the current line-up of US crew vehicles are docked to ? They're allowed to re-boost the station as well. At least it's a good thing that it was practically nothing... Although I'd have to wonder why they didn't realize it before the engines were started, given the lengthy hold-up (or maybe it is due to the lengthy hold-up ?).
  7. Yeah, I have no idea what the OP is trying to ask, even. Unless if they're planning to break physics - let alone physics, just the association of what your "spaceship" is. The ISS only includes all the stuff that's currently attached to it, it doesn't include the LVs and the used-up supply vehicles and their manufacturing plant here down on the surface of the Earth. the Earth only includes the physical body and (potentially) the objects where it falls into the immediate surrounding, possibly also the Moon if we're talking "Earth planet system", but it doesn't include the Sun. The Sun only cove
  8. The 350T version is exactly what's used on the ISS. The ISS is 400 tonnes in mass.
  9. I suppose it's not really useful for space travel though, unless we're talking stuff like the pressurized compartment or the electrical system etc. For the engines and the manoeuvres it's more useful to count it against the number of occurrences it happens. Airplane-level seems to need like another decade or more...
  10. Are the thrust for landing on the Moon that much ? Yeah, and it's a good thing they tested the thing (finally !). Only problem now is that even if they can swap the engines they'd need to run up and makes in all the fuel etc. again. Even doing a retest within next month is going to be the fastest they've been moving so far, but I really hope they'd finally gear up. 67 seconds vs. 480 seconds is waay too short. Unless if the only data they need is "oh look it can turn on, dunno how we'd do guidance".
  11. Sadly not actually in the quoted article, the article just says that NASA "will allow reuse of Capsule and Booster starting with Crew-2" but there's nothing that says it's what is in the manifest of Crew-2. Don't get me wrong, I myself hope that the propulsive landings of Dragon V2 will be used by NASA as well. It'd provide the precedent for Starship.
  12. Yeah, if they ended up being chosen for HLS then I can see the Orion spacecraft being pushed back to Earth by Starship. That'd be even less propellant needed on the Orion SM.
  13. Merlin was first tested in space from 2010. Merlin has only been propulsively landed back on Earth since 2015, and that's not the ones that goes to space. NASA hasn't accepted to use re-used boosters yet, although they're open to the idea. We'll see when a reused booster will be manifested for a crew launch on F9. Plus, Starship hasn't even had the thermal protection system tested at all. 2030 is the fastest time IMO, but mid-2030s is much more likely.
