Starship is a key part of NASA’s crewed lunar missions, and with government support, SpaceX is pushing its new experimental rocket to the limit.

    SpaceX did all the inspections for a falcon 9 booster in 9 days. No way they did a full rebuild in that time.

      Yeeeah, so, you didn’t read your own link I guess? Because it says, on a Tesla simp blog, that it was a refurbishment. Not an inspection.

      Here’s a nice write-up from NASA on what the SRB refurb process was. Feel free to read it.

        Again, I’m not trying to say these words have a single defined meaning. I’m saying that SpaceX’s reusable rockets are in a different category compared to SRBs. Call those reusable and refurbishable if you like, or call them anything else. I just use the reusable refurbishable terminology because that’s what everyday astronaut uses.

        Do you know the turn around time on an srb? I couldn’t find it in your doc or in the wiki.

          The only difference is propulsive landing. You’re obviously attempting to backpedal here, and it’s not working. SpaceX also refurbishes their units, you’re just bullshitting at this point. It’s painfully transparent.

            NASA stopped refurbishing their SRBs because it costs more to do so. SpaceX is able to drastically lower it’s launch costs because of the immense savings they can realize by a quick turnaround for reuse. That’s the difference.

              Russia has drastically lower launch costs than SpaceX. Justify it now.

                Mind giving your source? I found 2.5k/kg for falcon 9 vs 5k/kg for soyuz. The shtil is as far as I can tell military surplus and is now retired, so it’s costs aren’t really reflective of long term usage.
