00:00Project Orion on the other hand, which was halted in 1965 by the nuclear test ban,
00:07planned to generate thrust using nuclear explosions. An idea that was effective but
00:12politically sensitive and risky from a safety standpoint. Today, thanks to modern materials
00:18like ceramic composites, we have temperatures up to 3300 Kelvin under control, which increases
00:26efficiency, but development remains time-consuming and expensive.
