On 01 Apr 2004 05:02:59 GMT, in a place far, far away, "Jorge R.
Frank" made the phosphor on my monitor glow in
such a way as to indicate that:

Jorge, you should be a little embarrassed. Is there any reason to
suppose/assume that they are at the same node?

Not at this moment, no. But ISS' node regresses at 5 deg/day while HST's
node regresses at 6.5 deg/day, so the nodes will coincide roughly every
eight months. I assumed the smart thing to do would be to wait and perform
the transfer at the next common node. Of course, there's no guarantee that
ISS will actually be at the exact point when the nodes are aligned, but
once the two spacecraft are coplanar at the same altitude, it's a fairly
low delta-V phasing problem.

You're assuming an impulsive delta V. That's the most expensive
option...
