E - At the start of the mission, there will be a hive on the left hand side. Anchor up and it will be on the same ledge.

E - This is in the icicles on the ceiling in the room with a ton of Akrid. Just drop in and anchor up as normal, descend a bit and shoot it.

R - This is in the room with all the Snow Pirates. It will be on the left side between the boxes and the wall. You need to get on top of all the boxes and hug the wall to see it.

T - This is on the platform's bottom left corner, I did the drop anchor thing to see it, shoot it, then dropped onto the platform.

O - This is a tricky one to find, it is between a wall and a pipe on the highest platform in the room. The platform is on the east side of the room, get to the top and drop down to see it.

M - This is just before the boss. At the data post, go to the far north and drop off the edge so you anchor onto it, then descend a bit to see the mark to the north.
