Currently the cost of launching and supporting 2-3 people on a space station orbiting the earth with limited rations runs into the billions of dollars.

We are perhaps 30-40 years away from trialling permanent bases on Mars. The first pioneers will invariably have a high body count, For those who volunteer we salute you.

Todays science fiction often becomes tomorrows science fact - if not more so.

Try reading Becky Chambers 'Wayfarers' series of novels - especially 'Record Of A Spaceborn Few'


Aye, that one is particularly relevant. It describes the Exodus Fleet, where humans have been living for dozens of generations. The key is to recycle everything, from broken tools down to corpses.

Barring the invention of a Super Futuristic Magic Space Drive, you're still going to need reaction mass for your engines. One idea I've seen a few times (e.g. "Hull Zero Three" by Greg Bear) is to attach the ship to a comet and feed comet material into your engines. The comet is used up by the time you reach your destination.

so wait is it theoretically possible to put a space ship behind a comet someday in the distant future.I thought that was only sci-fi but maybe I will be proven wrong one day.


You already live on a space ship that follows a star around like a pug dog shadows its master. Its a natural space ship called "earth", and it orbits the Sun, while the sun itself cruises around the galaxy.

We can already put manned, or unmanned space vehicles upon, or in orbit around, or "behind", any celestial object in the solar system you want with technology we have today. We have landed men on the moon, and have sent probes out to every planet, and to go up close to asteroids.

Nothing special about that.

So we could wait for Halleys comet to return, and then send an unmanned probe, or even human astronauts, behind it to follow it back out to the outer part of its orbit billions of miles out, and then follow it back in again when it returns seventy some years from now. But there is no reason to do that.


But we cant do yet is "mine" asteroids, or comets, for their mineral resources yet. But that might well be possible in the future.

I dont trust the idea of going behind a comet for decades to escape planet earth because I came close to becoming a orphan from Heaven's Gate even if it is theoretically possible.


OMG! 8O

Your parents were involved in the infamous Heaven's Gate Cult????

That was in the like early Nineties. If my memory serves. Was in the news. We all talked about it, and comedian Richard Belzer joked about it.

you're right...it was a suicide cult, and even if your parents hadnt offed themselves they might have...um..neutered themselves (thats what the cult members had to do). Either way you wouldnt be here now.

Yeah...I remember how the cult leader had himself, and his followers, convinced that there was a space ship following Halley's Comet into the Solar system, and that that spaceship was going to rescue them from earth. And it all hit the news when the police found them all lying dead around the guys house from mass suicide. Glad your family survived all of that insanity.

well we had a family friend who had a friend who got recruited by Heaven's Gate and lost his retirement.We never did figure out what happened to him afterwards but i think he survived but he has been missing for decades from our social circle.Thanks very much.I am just glad my parents did not fall for it.This was in the early 1990's and then it all went down in march of 1997 but our friend of a friend went to San Diego and my dad said that he has no doubt it was Heaven's Gate.

The idea is less to "follow" a comet, and more to hijack a comet, kick it violently out of its orbit, and let your ship devour it. If that helps. The comet is toast.
