Back in the headlines, in the official, public space program, it's a simpler world but even less forgiving. As a NASA astronaut found out when a tool bag -- a more or less full tool bag -- got shoved and drifted away in zero-G. And it didn't have a line on it. And she didn't see it until it was out of reach. Wave bye-bye! And now it's one more thing to look out for around ISS. Per the report, it was a SNAFU from the git-go: a container of grease had given way and those lovely white-and-stainless NASA tools were greasy and gloppy, bad enough under pressure and barehanded and a nightmare working with the gloves on the kinds of spacesuits NASA and the Russians are issuing.
If there's are lessons here, one is, "You can't train for everything;" this was yet another of the NASA jobs that the team had done and done and done on Earth, some of it in the big water tank, every step worked out, every problem anyone thought of addressed. And the other lesson is that being highly skilled and highly trained doesn't mean you won't get distracted and make mistakes. It's what you do next that counts -- in this case, not going haring off after the greasy bag as it drifted out of reach was the right decision. It's a long walk home and they had duplicates of all the critical items.
* Some fine day I'll explain the complex arrangement of these vast starships, rough teardrop shapes about ten miles by five, just within the maximum scope and shape of a Level Two spacewarp. Standard thrust is applied at 90 degrees to the warp field, so the ship has a conventional and definite "up" and "down" and thanks to the elegant trickery of Feynman/Hawking "wormhole tunneling" (which actually isn't -- but don't ask me, I just change fuses and hit it with a hammer when it goes wonky), we get to add that vector to the warp on any angle we choose. It's a two-fer, gravity and fine maneuvering control: made of win! Or it could all be an elaborate joke.
