yeah the thud didn't want to be grabbed, even thought I came down on it several times, it just "popped" out and went flying off. I'm thinking of reverting, and sending the same ship back but with legs, hopping over to it, and retracting the legs to drop straight down on it. I think the problem is I came in really soft - the grabber doesn't appear to have anything like the port magnetism, and lightly bumping with it did nothing. Is there a specific velocity needed to engage it?
