NASA concept for a nuclear pulse spacecraft. A nuclear pellet is fired from the aft end of the craft and detonated, yielding far more thrust than conventional chemical rockets.
Last week I had mentioned the upcoming Ron Moore pilot “Virtuality”, set to air on June 26th, just a few short weeks away. That thread lead to a spirited discussion as to what might be the propulsion system of the show’s spacecraft, the Phaeton, a NASA style interstellar craft. In fact the Phaeton uses nuclear pulse propulsion, and I’ve asked my good friend Mike if he would explain how it works. Mr. Okuda has seen the Phaeton and witnessed the ship’s propulsion system in action, and he is delighted to elaborate on it for us. Take it away Mike…
Zefram Cochrane notwithstanding, most fans know that real scientists have very little idea how faster-than-light “warp drive” or “hyperdrive,” could actually work, or even if they’re possible. A lot of slower-than-light technologies seen in stories and films for reaching the stars are more grounded in scientific reality, like lightsails, ramscoops, and generation ships. Unfortunately, most of them involve extremely long travel times, miniscule payloads, or near-magical breakthroughs in engineering. (Sometimes all three!) Present-day rockets are amazing machines, but they have only a tiny fraction of the performance that would be needed to travel to the stars on anything approaching a human timescale.
But there was one incredibly audacious proposal for a propulsion system, using (relatively) off-the-shelf technology that would have been able to send massive payloads to the outer planets, and maybe even to nearby stars. Nuclear pulse propulsion.
