Trope-a-Day: Orion Drive

Orion Drive: As we mentioned way back in Nuclear Weapons Taboo, Eliera was always enriched in heavy metals, including the uranium family, and low on fossil fuels; and since the first set of uses of nuclear technology were all harmless civilian applications before anyone ever thought of weaponizing it…

Well, yeah.  Orion drives, or nuclear pulse drives rather, were an obvious development, from the early days of Project Phoenix (orbital shots), for satellite launches, and on through Project Oculus (near-orbit space station) and Project Silverfall (moon shots), and on through the early days of space colonization.  And not just for orbital maneuvering; they were used for ground launch, although replacing fission bombs swiftly with laser-triggered fusion pellets, up until they were eventually replaced with gas core closed-cycle nuclear thermal rockets, and eventually with mass driver/laser ablative hybrid drives for bulk cargo and trimodal NTRs for passengers, and eventually with beanstalks.

(Of course, this wasn’t entirely without consequences.  While the name of the Bright Desert originally referred to the glare reflecting off the pure white sand, the pleasant Cherenkov glow coming off both the glass-lined craters of the Imperial Orbital Launch Reservation and the pyramids of glass ingots stacked in the Burning Brickyard – the primary planetary nuclear waste disposal site – gives it an entirely new meaning these nights. Fancy nuke-resistant fallout-minimizing launchpads weren’t invented immediately, after all…)
