Also why is the actual volume of inspired and expired Nitrogen the same?

This is NOT my homework...

I need some help on a science project. It's about the Upsilon Andromedae planetary system. I have to 'create' a probe that will go out and search for habitable planets in that system. I don't even know where to start. I've done some research on the system and I've looked at other probes but I can't figure out what to do. If someone has some advice I'd be really happy and really grateful.
