Use the scenario posted below and dock with Mir. (No refuelling or scenario editing). Take all the time you want.
Comments/hints:
Obviously this is a plane change challenge.
Plane changes can cost alot of fuel if they are not done properly.
In this case the ISS and Mir have a Relative Inclination of 77.95 degrees, so the dV required (for a direct plane change burn) would be:
[math] \Delta_V[/math] = Required dV
[math] V [/math] = orbital velocity at time of burn
[math] \theta [/math] = Relative inclination
[math] \Delta_V=2\cdot\ V \cdot\sin \left(\frac{\theta}{2}\right)=2\cdot\ 7700 \cdot\sin \left(\frac{77.95}{2}\right) = 9686.31 m/s [/math]
In this challenge you have just 1/3 of the -direct plane change required dV- in your main tanks and 20 kg of RCS fuel.
Hint: An Earth orbit provides you with an advantage that none of the other inner planets have.
