The NZ/Netherlands aerospace company Dawn Aerospace is developing it's research scale vehicle, the Mk II: https://www.dawnaerospace.com/spacelaunch
They haven't detailed their staging system for the second stage yet, but it made me wonder: What forms of Spaceplane second-stage staging configs have been considered. Please include examples if possible.

  • $\begingroup$ This project seems to be 100% aiming at space tourism so I don't think the payload and upper stage is a given any consideration yet. $\endgroup$ Commented Aug 10, 2023 at 6:30
  • $\begingroup$ Uh, nope. They aren't even thinking of manned transport. Not sure what you thought the link was... They are aiming at small-sat and leo in the long term, and suborbital science in the short term $\endgroup$ Commented Aug 10, 2023 at 7:53

    $\begingroup$ The X-37B (uncrewed!) spaceplane is carried to space inside the payload fairing of an Atlas V or Falcon 9 rocket (both rockets have been used). China probably has a similar spaceplane that has been launched atop a Long March 2F rocket, although not much is actually known about it. The Sierra Space Dream Chaser is planned to be launched atop a Vulcan Centaur. $\endgroup$ Commented Aug 11, 2023 at 4:32

Here are some UK-centric designs:

  • Parallel - MUSTARD 1

  • Piggy back - Interim HOTOL, Space Cabb, AFRL SABRE concept 2Y

  • Underslung - Orbital Accessiii

  • Underwing - Virgin Galactic*

  • Payload bay - CNES SABRE TSTO concept 119

  • Bomb bay - AFRL SABRE TSTO concept 1Y

  • nose cone - CNES SABRE TSTO concept 219

  • $\begingroup$ @BlueSkinandGlowingRedEyes I think many of these might be on Aeronautix? $\endgroup$ Commented Aug 12, 2023 at 4:35
