looking for a cpl of gen (I think) fics

Hi, as title says I'm after a cpl of fics I've lost track of. Pretty sure both are gen.

First one is about the team visiting a planet where they find some underground Ancient lab or something. I think the team, minus McKay, get trapped in a section and Rodney has to get them out but he gets attacked by a wraith and almost dies?

Second is (I think) a short story where Shepherd is trapped in a Jumper floating out in space with a group of scientists and he locks himself in the cockpit?

Thanks for any help!
