- Apart from just generally evaluating how easy it was to do -- not very --
- he retrieved a micrometeorite experiment package that had been put on
- the Agena in hopes that it could be returned to Earth eventually.

- I think it's rated for the theoretical maximum shuttle payload, 65klbs.
- It's not rated for the full mass of an orbiter, which is why the station
- arm will eventually take over the capture-for-docking job.

- The arm really *can't* grab anything that doesn't have a proper grapple
- fixture on it, because the "hand" isn't a general-purpose gripper -- it's
- designed solely and only to grab grapple fixtures, and is very specialized
- for exactly that job.
-
- As far as I know, the success rate for grapple fixtures is 100%. They've
- sometimes had to proceed slowly and carefully, but I don't think they've
- ever had to abandon a grabbing attempt.
