I'm writing a story about a group of 6 astronauts, who are sent to as the first stage of colonising the red planet. the story opens while still on their ship and my thought was to introduce the crew all at once in a 'team meeting' kind of thing quite early on. However, I'm not sure if it's rushing the story too much. What do you guys think? all at once? one by one? I'm completely open to any suggestions.
