The scope of who is allowed to continue using it sounds like it is aligned with other US export controls (like ITAR and EAR).

Seems like many people are unaware that export controls apply to software as well.

BPS Space channel on YouTube made a collaboration with Mark Rober on a self landing rocket with a small engine, and all the experts they contacted would just stop responding the moment they asked something about the final phase of the flight. They later learnt that export controls bans those individuals from even discussing such topics with them.

  • Right. For those who didn’t catch the text between the lines, it’s because terminal phase precision guidance is basically the same tech as smart bombs.

    • Smart bomb targeting is more of a subset of the tech required for precision landing.

      Smart bombs just need to get to the target coordinates. A reusable rocket needs to get there with zero velocity, while pointed straight up, with minimal pitch/yaw/roll.

      Pretty much all of the barge landing failures shown in "How Not to land an Orbital Rocket Booster" would have been accurate enough to put a warhead on target.
