Homework Statement
Estimate the total delta-V required to perform a Hohmann transfer between the Earth and Mars, ignoring the gravitational influences of the two planets. The planetary orbits may be assumed to be circular and in the same plane.
Why will there be a minimum wait time at Mars before a return journey to Earth, via a second Hohmann transfer, becomes possible?
Homework Equations
v = [GM(2/r - 1/a)]^1/2
The Attempt at a Solution
Is this more simple than I think it is, Do I need to link conic sections instead?
Thanks.
