Short story set on Mercury

[Vimto]

Many years ago I read a science fiction short story which was set on the planet Mercury and have forgotten the title and author and would like to read it again.
The story was about a spaceship which had crash landed near to the twilight zone and two different teams of survivors had set up camps near to one another. I shall call them the goodies and the baddies. The life spans of these people were speeded up to ten days or so because of the increase in metabolism. Generations were born and died. The aim of each generation was passed on which was to reach the Mother ship and possible safety but because of the then perceived nature of Mercury there wasn't enough time at dawn or dusk to achieve this and people who attempted it were either caught in the deadly freezing night or the equally hostile boiling day-time temperatures. There was also the added danger of raids from the hostile camp. The hero of the story discovers a way of reaching the Mother ship along with his woman and they manage to escape from the planet and miraculously their metabolisms return to normal and they all live happily ever after! Sounds corny, I know and I have deliberately made it sound so but I did enjoy it. Can anyone help please with a source or suggest where I might enquire further? Thank you.

Ray Bradbury's "Frost and Fire" maybe?
