Profiles of Proposed Starships

+ 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?
Shadow-lance + intertial echo
Inertial Orlikon
Gyrane deceleration

Fascinating Destinations

From the notes of Duncan-Enzmann:

Model of a Torch

As soon as ships are built that can traverse interstellar distances above 959c colonization will explode. Robotics computers, resource glut, will mean at least 10,000 star ships moving out per year. Fascinating destinations to the edge of the galactic disc.

Numbers of Landfalls:
3 parsec 10 light year zone: 12 stars
5.5 parsec 18 light year zone: 96 stars (about 8 are white dwarf stars, others are yellow G sun-like, orange K cool sun-like, M crimson cold sun-like)
11 parsec 36 light year zone: 664 stars
15 parsec 49 light year zone: 1600 stars
31 parsec 100 light year zone: 16,000 stars
62 parsec 200 light year zone: 160,000 stars
125 parsec 400 light year zone:240,000 stars
250 parsec 800 light year zone: 2,000,000 stars
310 parsec 1000 light year zone: 6,000,000 stars
Total major and minor colonies: 6,420,000 in 300 years

30,000 light years to the center of the milky way
2,000 light years from the upper surface of galactic disc to the lower "surface of galactic disc

A large passenger carrying echo-Lance would cost in the vicinity of 5 billion dollars per ship. Even at 50 billion per ship the off-earth ship yards would work 24 hours a day year-in year-out producing ships.

Such a ship could carry a minimum of 5,000 and maximum of 22,000 persons; this would average 150,000,000 outward bound persons per year. This would in no way "solve" (if a solution is needed) the alleged "population problem" (if there was is or ever will be such a problem.) Such a migration would, however, open the escape gates wide for just about all restless souls.

It is not impossible that 300 to 500 years after star flight in vehicles that can move at speeds above 957c, that mankind, now in at least 1,000,000 settlements, will produce 50,000,000 to 1,000,000,000 ships per year which will thunder outward at close to the speed of light. Consider: the world today produces on the order of 50,000,000 motor vehicles a year. Wait - see what life will be when robots are fully developed.

For some people the most fascinating discovery could be an uninhabited planet, perhaps with unintelligent plants and animals that are not overly hostile. For other people and groups, such a land fall is not by any means the most fascinating, or desirable. But first let us consider Earth-like planets:

Probability of Earth-like planets, or at least planets with breathable atmospheres:

Parent stars

unlikely; about (around) type 1 stars - too hot, too short lived

likely; about type II stars -  just right = man galactic population

Likely; about F G K M stage type II stars

Consider photon-life zones about F G K M stage type II stars

And consider ERG (early red giant) ignition which will generate rocky terrestrial type bodies

K and M stars are more abundant so most planets will be cold, but nevertheless livable.

Without a moon (doublet like Earth-moon) oceans could dominate over continents, in fact planets could be quite Earth-like but with a few island-like land areas in universal oceans

Life on an island world could be enchanting, timelessly beautiful, eternal lotus lands

Cold dusty planets with rare salty ponds and springs gushing or trickling hot, warm and freezing brine would be common, the air would be breathable, water would be precious

life could be dreamlike on a vast windy planet wide desert with occasional snug oases. People on such a planet might well be semi-nomadic and compelled to travel yet again to yet other stars.

A passenger service might be comprised of 3 to 10 starships
the fleet depicted (illustration not found) is comprise of 6 starships each ship has a company of men, women, children who live aboard. The ships companies own the ships. the fleet is an independent city state that gains wealth, often as new ships, by carrying passengers to interstellar destinations. The fleet also establishes the passengers. Each chip carries 200 to 500 persons in its company. A ship in deep space can be operated by 3 persons.
