OK. This is something that should go with our proposed
public domain extropian software project, starting perhaps
with Adrians ion engine model. We could post equations and
a read-me file on how to do orbit mechanics. It really really
isnt complicated at all. We could even post rules of thumb,
such as it takes as much delta vee to change an orbit 90
degrees as it took to get it in orbit to start with. And it
scales linearly, so if you are in an 8 km/sec orbit, it takes
4 km/sec delta vee to change that inclination by 45 degrees.
Assuming we have plenty of time to change that orbit,
we still need to come up with a buuuunch of delta vee. spike
