The rainfall on mars is still sporadic. There are yet no permanent lakes or seas for algae to thrive in. Algae are grown in vats in greenhouses. After it rains, samples of algae are taken to any hollow that holds water. They photosynthesize and free up the oxygen in the iron oxide soil.
About this creation
Accessories are shown. The helmet is of a type worn by MarsCorp employees before the perfection of polarizing visors. It is more suitable for manual labor. Multi-day breather pack with commo link.
Good job! I like how it is simple, but rugged to get the job done. Is MarsCorp gonna evolve into a story line or just a simple creation you made? I like how you elaborated on the terraforming there too.
