Landing on Voeld
When you’re finally done messing around on the Tempest, travel to the Nol system, where you’ll find the planet Voeld. Land on the frozen planet, and after a bit of a rough landing you’ll be deposited on the surface, where your hardsuit will be challenged frequently by Cold Environment hazards (levels one and two!).
Note: Merely landing on Voeld will start the companion quest "Liam Kosta: Outpost Worlds".
Make your way southeast from the Tempest, following the quest marker and/or the lights. When you reach a narrow mountainside path, stop to scan some Iridium if you have the nerve (and the life support capacity), then continue up two ledges to find a conveniently-placed "Solar Heater", which will restore you life support. Probably could make s’mores, if you had the materials. Oh well. Missed opportunity.
The Rebel Base
Jump a crevasse to the south, then climb a ledge to reach the resistance base, where you’ll find numerous Solar Heaters to warm up near, as well as plenty of Angaran ships to scan… when they cooperate. Continue south through the base and when you spot an Ammo Box to the east, search behind some nearby crates to find containers to loot.
Continue southeast into a garage and loot some more containers hidden about, then proceed southeast through a doorway. Turn northeast when you get the chance and loot a lucrative container, after which head southeast, then turn northeast again and go through another doorway to reach the resistance leader - Anjik Do Xeel.
Approach her and some chatter will begin, respond to her threats as you will, after which she’ll refer you to a lookout. Once you’re done talking to her, loot some containers (there are several in the barracks to the southwest), exploit another vein of Iridium and do some scanning - in particular be sure to scan the Angaran Integrated Tech Node east of the holo-display of Voeld, as it’s worth 100 Heleus Research Data points. There are also plenty of quests you can start now, with no fewer than four points of interest on the map, but stay on focus for now - you’ll come back to these quest later. When you’re ready to move on, continue through the base to the southeast.
Exit back out into the cold and talk to a pair of Angarans named Beniska and Tseek. After a bit of friendly xenophobia they’ll point you in the direction of a Kett labor camp, and what better way to prove your loyalty than by killing Kett and freeing some Angara in the process? Exhaust their dialogue options to finish the quest "Meet the Resistance" and begin "On the Frontlines", then make your way north to find a site suitable for deploying a Forward Station, your first on Voeld. The Nomad is, unfortunately, essential to exploring this glacial planet, as your hardsuit won’t keep you alive long in the blizzard, and Angaran hospitality ends here.
