Daniel, you just beat me to it. The ISS is still traveling well below escape velocity. On Thu, Feb 26, 2015 at 12:46 PM, daniel turner via Utah-Astronomy < utah-astronomy@mailman.xmission.com> wrote:
Joe: Low earth orbit is still deep inside the gravity well of the planet earth. In terms of energy the ISS is only halfway to achieving an orbit around the sun. It's still a long way uphill to get anywhere. DT
Brent, Your answer touched on an issue I don't fully understand. How much thrust would it take to nudge the ISS, which is already in orbit, into another orbit that would sligshot it toward Mars? It's not as if we need to lift it into space. Thanks, Joe
