Have you been to the Challenge halls before?  I almost always find them on the Lua Extermination mission.  They're kinda difficult to spot if when you don't know what to look for.

Check out the wiki: http://warframe.wikia.com/wiki/Orokin_Moon

my mates and i are exploring the whole map. every door and such. and nothing is appearing

Just bad luck. Ever since the implementation of new tiles in the Orokin Moon tile set some time ago, the spawn rate of the Drift challenges has been a lot lower than before.

If you're still having trouble, try running Mobile Defense. The challenge rooms are all eligible to contain an objective console, so it might improve your chances of getting one of the rooms to spawn.

I'll help right now in game. I'm curious what mission you guys are doing currently, I will just PM you and find out.

Yes, Mobile Defense is what i have normally done. As most of the terminals spawn in the same rooms as some of the challenge rooms. Particularly the Endurance drift, laser one and the Agility Drift Organ Room

aye, Exterminate or Mobile Defense would be the recommended Missions to play to find these Rooms.
