[amsat-bb] Re: AO40 replacement !!!

[Kevin Muenzler]

I was watching a video a few weeks ago (YouTube I think) about putting
cube-sats ("triple-cube") in geosynchronous orbit using ion power.  They
would be launched to the ISS, unpacked and released during an EVA.  They
would slowly spiral out over several months to a permanent orbit.  I'll see
if I can find it again and post it here.

I'd be unstoppable if it weren't for law enforcement and physics

I am resigned to the fact we will in all probability never see another AO-40
(sobsob) unless one of us wins the lottery. We would call it the LRD bird
(if I won). As far as putting one together on the ISS, we would have to send
a "real" ham to the ISS., to put it together. Remember they busted a antenna
on the last one. The best chance is from our DL friends with the AO-10/13
type frame. Untill then we will have to be content with what we have and
when we have it. We can play around with interesting propulsion systems etc.
I realize we have smart people in high places within various organizations,
and trusting them is necessary. Finally if a HEO is ever on the horizon (pun
intended), they will come in droves.

How would it be assembled on ISS? You would have to build it on the ground,
document every step, take it apart and rebuild it to be sure the assembly
documentation is correct and then ship it up bit by bit. Meanwhile each crew
trains quite awhile on their respective increments aboard before they
launch. So, you would have to hope you train the right crew to assemble it
which means your upmass bits and pieces would have to make every launch they
are scheduled for. Being a ham radio satellite what do you think the
priority is should something more pressing come along? There goes your
trained crew, remember the broken antenna on ARISSat-1? The crew that
deployed it was not the crew that had been trained on the ground for that
deployment. Assembly of anything even remotely close to AO-40 aboard ISS is
unrealistic. The best chance of getting a so called replacement for
AO40 is to find a way to complete and launch P3D which is sitting on the
ground in Germany. Maybe they'd like to disassemble it, document it and work
shipping it to ISS via ESA?
