I recall a short story of a spacewalker (astronaut on an EVA to repair something) who gets hit in the leg by a small swarm of micrometeorites, which zip right through his leg. IIRC, he somehow figures they are in some sort of periodic orbit, and he's going to get hit again.
As I recall, the micrometeroids just flashed right through him. I do not recall how he determined they were going to come back, nor how he determined the period of their orbit (or even what they were orbiting.
Anyone know the story / author?
The story (IIRC) was in a collection of a number of short stories, I do not know if it was a collection by various authors, or a single one. It was "young-adult" fiction, generally written on a reasonably accurate scientific basis (or at least the author tried). Thanks
