The Atlas ships all have varying numbers of Quasar thrusters. These thrusters are often a headache for people, potentially resulting in various damages to the thrusters or the salvager themselves. And if you separate them from the rest of the ship before flipping the fuel shut-off switch, there's a crushing hazard as well; many dead Spares have met their ends in such an undignified and frustrating manner. Even for very experienced players, there's a bit of risk and urgency to fly through the flames if there aren't enough coolant canisters around.

I'd like to share with you the perfect technique! Just be sure to mute Lou.

First of course you remove the panels, cut the outer cut points, and grapple the nozzle into the barge. After that, you're left facing the back of the thruster, four fuel-pipe cut points, and a random number of coolant canisters.

At this point, attach a tether from the back of the thruster all the way to the back of the salvage bay. The mass of the ship will hold it in place for now, and the tether will safely remove the thruster after it has been cut loose.

Now you're ready to use the coolant canisters. Previously I thought that positioning one right in front of the fuel-pipe cut point was clever, as the flames would destroy the canister, releasing the coolant which would then put out the flames. The problem with this was that it required precise positioning and one coolant canister per fuel-pipe, and you never have enough to use four coolant canisters on every thruster. You'd still be left with some fuel-pipes on fire.

But this is the technique I'd like to share. Rather than carefully positioning one coolant canister at each cut point, you can be a bit bolder. When you grapple the coolant canister off the thruster casing, you're going to want to hit it against something lightly; not hard enough to destroy it, but just enough to cause it to start leaking coolant while you still have it grappled. While you're still grappling it, move the leaking canister right next to a fuel-pipe cut point, and give it about a second to freeze the first segment of the pipe and the cut point. Using the same leaking canister, repeat this with the three other fuel-pipes and their cut points.

You'll end up with all four cut points safely frozen ahead of time. The thruster will probably freeze too, but that's fine. While they're frozen, use the laser cutter to carefully melt all four cut points. You'll see a brief flame effect that quickly stops, and Control will tell you there's fuel instability like normal, but there won't be any fire.

When the last one is cut, the thruster will be pulled out of the opening by the tether on the back wall, and you can safely enter the thruster casing to pull the fuel shut-off switch and crack the casing in half.

I hope that this technique will help new and old players alike to safely overcome Quazar thrusters. Be sure not to cut the thruster casing off the rest of the ship before pulling the fuel shut-off switch, and you'll have a 100% safety and success rate! You'll also be able to enjoy a more relaxed salvaging job, without needing to fly through burning fuel.

Alright alright, that's enough loafing. Get back to it, cutter! And you, "Hal"! Stop abusing power for your petty hatreds and bigotry!
