Heat management, recycling, $, and space ores

Darren, etal.,

You are correct. I believe the force for a solar sail is on the order of 1
newton per square KM. Launching and retrieving space craft will have much
larger affects, especially if a catapult is used.

The use of nuclear or solar powered electrical plasma rocket engines is
perhaps the most efficient means of orbital modification over periods of
many months.

Cheers,

Tom
