  1. What if: Apollo 10 landed on the Moon?

    It's not likely you'll be able to find enough to remove, in-flight, to make up for lacking the better part of a metric ton of propellant: Ascent stage data starts on page 113 if you want to start trying to find how to lose that weight. The entire inert mass of the vehicle is about 2075 kg, and...

    Threadmarks: author's note: e of pi

    e of pi’s notes: Happy April Fool’s everyone! So...this project started about a year and a half ago, as an idea of a quick-and-dirty timeline to explore what would have to happen to see an orbiter-derived station, primarily drawn from the Ware & Culbertson studies, actually realized. The idea...

    Threadmarks: Part 33: First and Last. Enterprise outlasts its sisters. Shuttle-II flight tests and epilogue.

    Boldly Going Part 33 Despite the success of Spirit in the captive carry and glide tests, ground testing of the Shuttle-II’s systems could only go so far. Many of the critical capabilities of the orbiter could only be tested inflight, during ascent or orbital operations. The first Shuttle-II...
  4. WI: Japan don't attack Philippines/Hawaii in 1941: how does US react

    There's a few interesting pull quotes from Gallup's polling about the Pacific theater that I went through here: https://www.alternatehistory.com/forum/threads/what-if-japan-only-declared-war-on-britain-and-the-netherlands-and-not-the-usa.498705/post-21194779 Most notably:

    Threadmarks: Part 31: Orbital refit in progress builds a new hangar bay.

    Boldly Going Part 31 Space Station Enterprise’s augmented crews began the work of assembling the new hangar bay fixtures inside the liquid hydrogen tank in 2015. Despite the benefits of working entirely in IVA, crews aboard Enterprise still found the process of welding fixtures to the tank...
  7. Boldly Going: A History of an American Space Station

    Quite so. The real mystery: somebody took home the 2000 Army-Navy tape, but who? Indeed. Take a "walk" around the close up view of @NorangePeels 's cutaway and check out the walls and corners. A lot of clutter, old posters, and a few references for the eagle-eyed. Some fine work! The solar...

    Boeing Phantom Express: Rockwell X-33: Teledyne Brown Engineering Spaceplane: Less of a lifting body, more of a tube-with-delta-wings. Most of these designs and others are propellant tanks which are empty during descent, meaning even if they have the same overall length/diameter as the OTL...
  9. Timeline Elevator Pitch: Stuck with The Right Stuff

    I don't think either of these work. A ingle person in orbit for an hour or two is clearly only the first step to EVA, docking, and more that Mercury can't do without effectively total overhaul from the keel up, much of which is rendered much easier and safer by a two-person vehicle which is at...

    Threadmarks: Part 29: A hanger needed, a tank available. Enterprise acquires a shuttlebay.

    Boldly Going Part 29 By 2010, congressionally approved programs were underway both to replace the space shuttle and to convert the existing Conestoga landing system into a fully reusable vehicle. At this point NASA began to turn its eyes skyward once again, toward the goal that had sat at the...
  11. Timeline Elevator Pitch: Stuck with The Right Stuff

    If, in 1961, Apollo is being cancelled, then finding that extra $12m will be even easier than IOTL--it's a trivially small amount of money even in NASA's budget then ($744m in 1961), and if it's the only way to get two people into space at a time, then they will find a way to make it happen.

  13. Boldly Going: A History of an American Space Station

    The idea is something between the Teledyne Brown Engineering (TBE) spaceplane and an orbital version of the Rockwell X-33 or Boeing's Phantom Express (but I repeat myself). Essentially a cylindrical ~4.5-5m fuselage, delta wings, SSME on the back, RL-10 OMS though probably two and not six. (The...
  14. Boldly Going: A History of an American Space Station

    Yeah, my understanding is there's a vestibule between the end door (and possibly the airlock-end door) and the tank wall, with insulation between. The inner door is removed or left open, and then the outer door which is a "proper" pressure hatch with sealing rings and the window is used from...
  15. Would SpaceX still exist if NASA replaced the space shuttle with the X-33 and had not spent almost a dozen billion on Constellation?

    The VentureStar design had enough technical issues I don't think it could have succeeded. However, if NASA had funded a second generation large reusable vehicle in the early 00s, I agree with others it's quite likely SpaceX founders and never launches anything beyond Falcon 1--if they even stay...
