He then described the LED's he was seeing, and it was pretty apparent that he didn't knew how it was _supposed_ to be look like. This became even more apparent when they discussed how many antennas are actually supposed to be attached to the satellite. One said : "I was here 3 months earlier and there was only one". Is that the way to check that the device is in a correct configuration ?

IMHO it is a miracle that the solar arrays are still intact, and I would not be surprised if they broke of the second antenna because of careless handling.

There are procedures to follow and checks to make before the sat is deployed. If it would have come to the crew, they would have just pushed it out and be done with it. This is all financed by donations and build by volunteers. Many people put a lot of effort into this. Its not that we can just build and launch another one, if they screw it up. I think its simply unexcusable that the correct configuration of the satellite has not been confirmed even before the spacewalk has started. Very disappointing.

I think the reality of this is that activities like this need a champion on
board who is truly enthusiastic about this, as opposed to another thing
that ground control wants.
I do not know any of the history or politics behind this. I could see it
being that ham stuff onboard being pushed more by Americans, and
there has been some kind of subtle shift in things now that the Shuttle
is no more?
It's rather like getting time on Hubble. I once talked with someone who'd
done observations with it, and there was a lot of jossling over who did
I am sorry to hear of the problems that happened. I suppose this is a
good lesson for kids, that nothing in space should be taken for granted.
This failed to be deployed once before? So a lesson to learn.
