In reply to above, there is no penalty to mission rewards unless you die during the mission. Ending a mission goes like this.

If it's just you, you leave immediately.

If there is one other person, one of you must be at the extraction point to start a one minute timer.

If there are two more people, two of you must be at the extraction point to start a one minute timer.

If there are three more people, two of you must be at the extraction point to start a two minute timer, with three people starting a one minute timer and all four causing an extraction instantly.

(Feel free to correct me if I'm wrong, but that's what I recall at the moment.)

The last person is probably sweeping for any items they might've missed. When you need supplies, you really don't want to miss anything. If it's a Void mission*, Void Sabotage, or Earth Sabotage, they might be hunting down the Caches that spawn.


 * All Void missions have a chance to spawn what are known as Treasure Rooms. They hold rare mods and large amounts of resources at the end of a small agility course, which tests your skills at maneuvering with your Warframe.
