in Welcome to our walkthrough for the Heart of Mars mission in Starfield! Heart of Mars is one of the misc missions you can pick up at Cydonia. To start it, speak with Layla Pulaski in the Residential section of Cydonia about the Heart of Mars. She can also be found in the Central Depot mining ore.
Find the Heart of Mars
Head for your ship and use it to return to space. When looking at Mars, land at the Cave. Head inside the cave where you’ll find the Heart of Mars (Titanium Deposit) on the ground in the form of a small rock.
Use your Cutter to extract the ore.
Return to Laylah
Report back to Laylah in Cydonia. As a reward, you’ll get to keep the titanium and earn 100 XP.
