Last week, the National Aeronautics and Space Administration (NASA) revealed its five finalists for the ongoing contest, which hopes to finally put to life how humans could thrive on mars and possibly, other planets as well. 

NASA’s 3D-Printed Habitat Challenge began back in 2015 and is currently in the third stage of the competition, CNN reported. According to NASA, the goal of the contest is to “build a 3D-printed habitat for deep space exploration, including the agency’s journey to the Moon, Mars or beyond.” They also added that the “challenge is designed to advance the construction technology needed to create sustainable housing solutions for Earth and beyond.”

NASA announced the three finalists of the latest round of the competition through a tweet.

Team SEArch+/Apis Cor won first place in this round of the competition with a twisted building design that propagates “continuous reinforcement of the structure,” according to NASA. The design also features pores that helps light come in. Team Zopherus won second place by designing a habitat that is created by a “roving mobile printer” and team Mars Incubator secured third place with a modular-like structure.

The three finalists received around $33,000 (around Rs 23 lakh). The finalists will now be heading over to the last event of the competition on May 4 — an event in which the teams would have to present a “3D-print scale models of their designs.” The winning team will receive $800,000 (Approximately Rs 5,53,84,800)
