Once you're out of your ship, talk to the Vullard. Accept his offer for work if you have the Harmonic Plating (or better plating) and the Ship Tether, as you'll need them to do this job. Get back in your ship and head for the comet (you'll find it soon enough).
( ) Retrieve Core Sample from Comet.
You'll need Harmonic Plating and the Ship Tether to do this job. Once you do find the comet, line up your ship so you're running along side it, just behind the core, and then make your way in to the comet's tail, so you're directly behind the core. Shoot the core with all you've got, and then once the Square icon comes up, press Square and get out of the comet's tail.
