Once we have a space elevator the problem of escaping earths atmosphere won't be a problem, then we will just take a shuttle to the mar's space elevator and whala there you have it...

We don't have any material capable of building one though. It's probably best to pursue more practical options until we do.

You seem to be misinformed.

For some reason when I hear the words space elevator I just cringe. The idea just sounds ridiculous.

I think the Origin idea seems like a good one - http://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)

Using the power of nuclear explosions for thrust. it would need to be constructed in orbit, but it seems that the technology and materials exist. The limiting factor is humans themselves, but with robotics this would not be a problem. Communications however probably would be a problem.

This is exciting news and progress! As long NASA knows what they are doing and i know they are! However they will need to design a special suit to withstand months of radiation too. So that's the main important thing when it comes to space traveling especially if we wanna travel MUCH further in the stars.

Good read. Thanks OP +Rep.

Anyways,
I wonder if nasa is going to try having rotating living quarters to create artificial gravity, surely on long voyages to mars having some level of artificial gravity would go a long way to helping stop muscle decomposition

Article says the program was funded by the Air Force and then given to the newly founded NASA. The military does a lot for the advancement of science.

Yeah, if we're going to get serious about space travel, we need to start having launch stations at the Lagrangian points.

I think he is thinking more of the, Take off from earth like a Plane, and exit the atmosphere gradually. Then be able to re enter the atmosphere at a later date.

If he means to use a shuttle to land on Mars, it may be possible but Mars is still very hostile, I dont believe the Shuttle would survive it and actually get back into space.

As for the other moons forget about it, there wont be any humans going to Europa/Enceladus for a long time. Which I think is a bit more important than Mars, I dont think mars will ever truly be relevant to Humans, maybe as a Mining outpost but I get the feel the expenses would be far greater than the rewards.

Alternatively what I would like to see is whats inside those 2 Ice moons. they say warm Ocean exists under the frozen surface, so its conceivable that we can get a Multi Function Probe out there that could drop a Huygens like probe to the surface. Try to land it at a hot spot and it might be possible to Melt your way through the ice eventually. I assume the Huygens like probe would need to be tethered though, cant imagine it sending/receiving data very well through a Mile of Ice.


Space Elevator is far off in the future if at all even possible. the Logistics of it all just don't make any sense to me, how can you actually build something like that lol

Building an outpost on the Moon is a good strategy, if we assemble our space toys in Space, then we can cut down on the need for a huge % of the fuel needed to get things out of atmosphere.


So much fun just thinking about all of this.

I think the moon is the way to go...we could even build earth satellites there and get them into position with little more than maneuvering thrusters. Provided there was enough water on the moon for a station to be largely self sufficient I think it would even be profitable once you got it up and running.

I feel sad that I won't get to see the most amazing things. It's just a matter of time.
