I read this short story maybe in the late 1980s or 1990, probably in an anthology. I read it in English.
The main charater was an astronaut, male I think. He was in a spaceship orbiting what I think was Earth's moon but could have been another planet or moon without atmosphere. Something happened to his ship and either it disintegrated or he had to abandon it. He's left in orbit just in his space suit and either the orbit is decaying or isn't high enough and he is going to crash into a mountain/cliff. He is rotating as he falls/flies and I remeber a part where he said it became incredably important to him to know whether or not he will be facing the mountain when he crashes into it and dies. I think he was in radio contact with other people near the moon throughout his ordeal.
At the end he is saved because the ship/remains of the ship are on a path ahead of him and crash into the mountain, creating a hole/gap through which he is able to safely pass and I think this then allows enough time for him to be intercepted and rescued.
