Has anyone tried to run a Traveller or other SF RPG set in our Solar System, before FTL travel? I'm considering developing a Traveller rules variant or entirely homemade ruleset based on such an idea.
How about energy? Energy is more freely available in space than it is on Earth and Spaceshipone has flown. Its just a matter of time before private enterprise takes over space travel leaving government agencies and their billion dollar spacecraft in the dust. A space elevator would eliminate our dependence on rockets and turn access to space into a simple mechanical problem. There is alot of economic potential in space that would be exploited one launch costs are down. Anyway the technology of the 2030s is more concrete than the nanotech driven future of the 2100s. One has to give some implausible excuse as to why computer technology has lagged and why human beings still have a significant role to play in the Solar System. Its easier to advance space science than it is to lag computer technology for 100 years.I think the reverse will be more likely: interplanetary expansion will trail economic development on Earth. Without Travelleresque grav tech lifting costs are too high by exponential factors of ten.
A radical new structural material is insufficient to drive economics of space exploitation, unless perhaps space is the only place the material can be produced. But then the material becomes more expensive relative to material strength than ground-made materials.
Why do you think we have to wait until the 22nd century before we go into the Solar System? What's so hard about space travel that it takes 150 years to accomplish? Aren't you aware that 100 years is a long time? A lot was accomplished in the 20th century for instance with regards to transportation. in 1900 we had no heavier-than-aircraft and our lighter-than-air aircraft flew only at the mercy of the wind. Cars were a recent invention and most travelled by horse or horse and buggy; We've gone from that to Jet aircraft, and cars have driven horses off the highways. Also in the 20th century we've developed electronic computers, wireless networks, the Internet and even achieved spaceflight. And now you think the next 100 years will pass as if nothing happened. We might as well cut the 21st century out of the history books and have the next year after 1999 be 2100.A much earlier GURPS setting called Terradyne (copyright 1991) may be of interest to you.
It is set in 2120 and could be described as Transhuman Space without the biotech and AIs.
Except that the radical new structural material is what allows a solution to the lift cost problem by way of making the consturction of a workable space elevator possible.Originally posted by Straybow:

I don't, I was just posting on another non-FTL solar system settingOriginally posted by Tom Kalbfus:

A couple of things spring to mind.What's so hard about space travel that it takes 150 years to accomplish?
And the replacement for the shuttle is... where???Aren't you aware that 100 years is a long time?A lot was accomplished in the 20th century for instance with regards to transportation. in 1900 we had no heavier-than-aircraft and our lighter-than-air aircraft flew only at the mercy of the wind.

No.Also in the 20th century we've developed electronic computers, wireless networks, the Internet and even achieved spaceflight. And now you think the next 100 years will pass as if nothing happened.
No.

Good for you, I say. We need people to be optimistic about the future and humanity's potential. I for one would love to see your predictions come true by 2030 (and I hope they have anagathics by then as I'll be in my sixties).If I'm overly optimistic in prediciting mass space travel by 2030, so what?
I hope soPeople in the 1970s predicted the same thing by 2000 and they were wrong. I think that gives me more of a chance of being right due to the process of elimination.
Don't the Japanese still have plans for space hotels in the near future ,20-ish years hence?I think part of the problem is that the US government made space travel look so hard, they spend billions of dollars at it and didn't accomplish very much. Entreprenuers were discouraged from investing in space transportation except for a few people who were considered excentric. Now that SpaceShipOne has reached space, perhaps the majority of venture capitalists will reconsider. If the excentrics can actually build a spaceship that works perhaps they weren't so nutty in the first place, perhaps some may actually know what they are doing. I think alot more people are going to consider private space travel now. Investment dollars should be easier to come by now that the concept is being proven. OK, so we didn't have Lunar Vacations in the 30 years from 1970 does that automatically mean that we must wait 100 years or should we try for another block of 30 years? If I'm wrong I'll be almost 70 by that time and unlikely to wait another 30 years, for now it makes a perfectly suitable setting.
Make it 2050-ish and you've sold it to meComputer technology is advancing quite rapidly on the other hand, it seems to me that if humans don't break out into space in the next 30 years, they never will. If you want to play a character in a realistic Solar System Adventure circa 2100, you will be playing either a robot or a cyborg or augmented human. At the rate computer technology is advancing, computers will certainly be able to out think humans by 2100; by 2030 however they should be about even, that is the main reason I prefer 2030. The next 30 years is our next chance to do it ourselves, afterwards computers and robots will do everything for us if they don't replace us and Humans will not find anything really useful to do.
With very large space ships that are rotated to simulate gravity and adequately shielded this presents no problem. The ships are produced with in space resources (asteroids, the Moon etc.) Only the equipment to process these resources needs to be lifted from Earth. If launch costs drop, then you can lift this equipment and turn asteroids and moon rocks into interplanetary spaceships. A 1,000 meter diameter spaceship can rotate twice a minute to produce adequate gravity and it would provide plenty of radiation shielding even during Solar flares. Ion rockets or mass drivers would slowly accelerate these ships toward their destination and the colonists would grow their own food and regenerate their atmosphere on the way.Secondly, manned missions to planets other than Mars and Venus will still take months to years using the rockets you've suggested and the jury is still out on how well people will adapt to long duration spaceflight - effects of radiation, microgravity, psychological pressure etc.
Any expendible rocket can replace the Shuttle so long as its payload capacity equals it, the Delta IV does for example. What really is going to get us up their however is a space elevator or a scamjet. Nuclear rockets could be used, but environmentalists would object.And the replacement for the shuttle is... where???
And our brains are beyond this limit? No, when processor chips reach their limits, computer companies will produce multiprocessor chips that run parallel, eventually these chips will execute more compute cycles than the human brain.No.
I think current electronic/computer technology is reaching its physical limit, but more and more ways are being found to integrate it with everyday life to such an extent you don't even notice it.
Fossil fueled tranportation needs an alternative to be found as the odds are stacked against it.
Again, Tom, you're making statements that have little basis in factI think part of the problem is that the US government made space travel look so hard, they spend billions of dollars at it and didn't accomplish very much.
Urban myth. The design blueprints are still on file. We have not "forgotten" how to get to the moon. It is more a case of political will to do so.Originally posted by Malenfant:
Do you know that NASA has actually forgotten how to get to the moon? There's nobody around anymore who knows how to build a Saturn V, and I'm sure I've heard that the blueprints have been lost.
