YES, BUT WHEN DO I GET MY ORION NUCLEAR SPACECRAFT? Report recommends NASA accelerate space nuclear propulsion development.
There’s actually an argument that the Outer Space Treaty may override the Test Ban Treaty to make nuclear explosions used as part of a space propulsion system legal. I spoke at a space law symposium on that last week, and was surprised at how well it was received, even by standard international law types who aren’t spaceheads. I guess I’ll have to write that article now.
