+ 1000 miles/sec / lonely scout / Fox-H / unmanned / Chemical, ultra-planetary probe.
12 super-cargo rockets delivered over 8000 tons to Earth orbit. Then with a slow very efficient transfer orbit, (FLOX-H) swung out past Jupiter, Saturn, in past Jupiter for a solar gradient plunge, then out again past 1 or 2 of the gas giants. FLOX-H could hove out toward the stars at better than 1000 miles per second.
+ 1000 miles/sec / solar system urbanizer / Orion-A / manned / very fast solar system explorer / fission.
Was a beauty; 210 to 500 tons mass, it could have made manned landings possible on Mercury, Mars, the Asteroids, the moons of Jupiter, Saturn, Uranus, and a 2 to 4 months round trip to Pluto - in the 1970's and 80's.
+ 45%. c / 84,000 miles/sec / Orion / cheapest autopilot - a-human / nuclear interstellar probes / fission.
Orion-B was to fly in the early 1980's as mankind's first nuclear interstellar probes. I would have like to have volunteered for a one-way trip, Orion-B could not decelerate.
5% - 95$ c. / 10,000 miles/sec / Æsir (mini-lance) / small manned star-ship and mini-lance (a hint that the media and public did not notice) generation ship / fission.
Æsir was the first manned star-ship I designed. It carried 18 people (suggested five men, eight women, five children, it could carry up to 80 people) It decelerated with a primitive lance, aided by magnetic and electrostatic drogue against the galactic field. It could recycle air,water, and food. It carried two vacuum landers and a small ANP vehicle. People would parachute from the ANP to spare it landing hazards.
12% c to 20% c / 28,000 miles/sec / Pulsed Torch / slow boat / manned fully found star-ship / fusion, fission, augmented.
New York Academy of Sciences basketball on Ashcan. This ship carries a crew minimum of 500 (men women and children). It can carry perhaps 10,000 passengers. It can refuel itself. It carries ANP planetary landers, it carries vacuum landers, is equipped with mini-factories. Each ship is quadruply redundant. Ships move in fleets of 3 to 12, or more.
+15% - 35% c / 40,000 miles/sec / Torch Ship / slow boat / manned fully found star-ship / long voyage / fusion.
Published widely about the time of Daedalus studies, powered and propelled by totamak/magnetic bottle (after burns, dumps spent fuel into exhaust).
+ 99.99% c / 186,000 miles/sec / Echo-lance Dragon / manned long passage star-ship / fusion, or fission, or fission fusion.
Echo-lance 1) Lance 2) inertial echo 3) impulse energy converter 4) vortex 5) e+ p- 6) gyrane 7) orlikon (inertial) 8) refuels mass ratio two orders (approximate) better than the Torch.
C+ 20% / Shadow-lance / a high power echo-lance/ manned or unmanned / FTC interstellar probe / long passage.
Diagram gradient passage past neutron star 1) gravity 2) c - impulse 3) gradient sling.
20 - 100% c / FTL Hyperion - C ( Draken) / FTL fully found manned star-ship / galactic imperial Earth.
Cosmic constraints p = po (1 – d/D) where (d = D). "Missing mass" force to Andromeda at 1,000,000 light years it is still a 10,000 Earth year trip. And: where is everyone? But the converse is: why isn't someone else writing this book?
