Objects do not necessarily 'freeze' in a vacuum, although the weightlessness that often occurs with vacuum gives one the impression an object is 'frozen' in the vacuum of space. In Dead Space, the noticeable absence of sound (except the audio vibrations picked up through Isaac's magnetic boots) simulates the eccentricities of vacuum. Since there is an absence of a medium in vacuum, liquids, gasses, and plasmas behave without the benefit of an environment. When solar radiation hits interstellar objects, their surfaces heat up rapidly and vice versa due to this lack of insulation. The air which surrounds you is absent in vacuum. It is a medium (or lack of one) that is chiefly devoid of matter.

Vacuum is possibly one of the most alien environments known to man. Whack enemies and smash the energy capsule to unlock the next door. Take the lift upstairs and use kinesis to move the treatment unit on the track to make your path obvious. Once that occurs, release the kinetic hold you have and the battery will automatically activate in its respective slot. You will see the battery 'flick' into the port. If you are having difficulty fitting the battery in (as you will shortly in Zero Gravity), move the battery straight into the hole. Use the kinesis bullet on the battery near the dead lift and insert the cell into the battery slot. Watch out for the pulse ammo schematic you find in the office with the twitching corpse - there will be an ambush. Notice there is a node locked secret room and free power node (1 of 3) on the lower level of the first room. Use kinesis to move the large treatment unit aside. Head into the zero gravity therapy section. There are two fetch quests to get to your third fetch stick (and the resulting exit).

Otherwise (for your first round), enter the security station for the medlab and make a save. There is a work bench in the Zero G Therapy area if you need to upgrade your items. If you are replaying the game (and have collected all seven weapons), your inventory is now complete.

When you arrive at the new chapter, take the Kinesis Module.
