I am trying to locate a story I read 30-40 years ago. The story starts just after the space ship explodes. The crew knew the problem was coming and all had life support suits on. The story was them talking to each other on their radio/intercom while they drifted helplessly apart. One guy was caught in a comet's tail, and he said he was glad he would get to see the universe. One guy was caught by the moon's gravity and was pulled towards the moon. The last guy was caught by the Earth's gravity and reentered our atmosphere. The story ended with a mother and daughter watching a falling star.
