I found this video guide short and straight to the point, with the exception of that it is missing 2 of the 15 astronauts. There are 2 additional videos showing those locations. Astronaut 11 can only be seen with a sniper rifle, although spraying with an assault rifle works as well, even though you can not see it. Number 14 can also be hard to see, look from a distance to see just the tip of the head or try to cook a grenade on top of it.



#1 - Top-left of Cargo Bay Ceiling, while having your back facing the teleporter.
#2 - Barrier to the right of Racin’ Stripes
#3 - Bathroom Garbage Can (Theater)
#4 - Ticket Booth on front of Theater
#5 - Top Balcony outside Theater (burning houses)
#6 - Under Staircase to the left of Bomb Stoppers
#7 - Down Pit, near 'Tuff 'Nuff, on the floor
#8 - Inside Barrier next to N31L’s head
#9 - Water Treatment under stairs, when going back to spawn on right hand side
#10 - Outside map by pole near Change Chews
#11 - Outside map behind Pack-a-Punch (can only be seen with Sniper Scope)
#12 - 2nd Window across from Pack-a-Punch
#13 - Sewers under Catwalk
#14 - Top of Glacier to the left of the Pack-a-Punch Portal
#15 - Inside floor grating above Proteus

9 Can be collected almost right from the start, just open the one 750 door towards water treatment from the start, then head down the stairs, turn around and it's on your right hand side.

Then open up to cargo area, collect number 1 and head through the portal to theater.
2, 3, 4 and 5 are all in the Theater/Shaolin Shuffle area (through the teleporters).

6, 7 and 8 are all pretty close to oneanother, best collected in order 6, 7, 8 as well.

10, 11, 12 and 14 are all outside.

13 and 15 are pretty much next to oneanother. When facing the Prometheus, turn 180 degrees and head to your right towards outside. Then turn right again and look down in front of the barrier. Head back and turn left up the stairs, then before you enter the area with bombstoppers and Tuff Nuff, look down into the floor grating and the last astronaut is in there, facing the left wall inside the grating.
