This chapter of the Breathedge guide explains how to unlock an air balloon, a device that increases your lung capacity, so that you can stay in space longer.
To extend the time you can spend in space in Breathedge, you need to build an air balloon. First, get the blueprint: go to the wreck underneath your base. Next to it, closer to the rock wall, you will see a filled balloon.
When you get closer to it and examine it (you do not need a scanner for this), you will get a new blueprint. Go back to the capsule to use it.
Condom, which is the main element, can be obtained by searching the flying lockers. It is not a common object, but you will find it without any problem by heading to the area below the ship with a pink hull. Be sure to put the item on after you've crafted it.
