With some minor adjustments, it should be possible to produce suit upgrades from basic machinery design, miniaturised to be wearable. The most obvious upgrades are a better solar cell and cold insulation to operate at higher efficiency on this hostile planet. You're going to need to use a Hydrojet Cutter upgrade on your Manufacturing Plant for this!
To use a suit upgrade simply craft one and keep it in your inventory.
Your environmental suit is the most advanced piece of exploration engineering known to man. Unfortunately its utility depends upon a modular upgrade system currently beyond our manufacturing capabilities. It is time to look into how you can create your own upgrades away from the factories back home. You can use a bit of help surviving in this harsh environment.
