Hi Dan, I have heard of that -- it's a fascinating idea. On the question of structural weakness: I wonder if special struts could be built onto the ISS to make it possible. Or if some ISS-like orbiter could be built from scratch with the idea of shuttling between Earth and Mars. Thanks, Joe ________________________________ From: Rodger C.

Have all of you been paying attention to Elon Musk's idea of a one-way trip to found a Mars colony? Dan On Nov 28, 2012, at 7:03 PM, Chuck Hards <chuck.hards@gmail.com> wrote:
Several ion engines, at strategic points. A single thruster, even at very low thrust, would be structurally unsound over long periods of time. On Nov 28, 2012 6:44 PM, "Daniel Holmes" <danielh@holmesonics.com> wrote:
That was my first thought. So you probably could strap an ion engine or two to it, but I'm not sure they have enough thrust to break earth orbit. But it'd be cool to rename it the ISS-TIE. Sienar Fleet Systems wasn't founded here, but we could pretend.
Have you heard of the 100 year starship project, Joe?

VERY low thrust only. It would take years to decades. The ISS isn't designed for interplanetary thrusting, from a structural standpoint. Station-keeping and minor tweaks to avoid collisions only.
Good question though. On Nov 28, 2012 6:11 PM, "Joe Bauman" <josephmbauman@yahoo.com> wrote:
A question for the group: what is the feasibility of attaching
propulsion
units to the International Space Station and taking it out of Earth orbit, into Mars orbit, and back again?
