How about something Apollo13 style? Like in 2125 AD or something....
For example:
Scientists at NASA have recently recieved information that tells them the surface of Venus has cooled enough for human habitation, and that the cooled lava has formed a supercontinent. They also have discovered that there are huge fresh water seas, but the carbon dioxide level is so high that it is toxic.
A team is sent to Venus to experiment with the growth of plants.
It takes only 10 days to get there with the advanced fuel recently discovered, and they will spend 4 days on the actual planet, with a return trip of only 8 days.
But on the return, something goes horribly wrong....
Just an example!
