Inspired by The Martian? NASA could use your help.

The space agency on Wednesday announced it needs help building "deep space habitats that will give astronauts a place to call home during long-duration missions" like a journey to Mars. If you're up for the challenge, NASA is now seeking proposals for prototypes.

"NASA's Orion crew spacecraft and Space Launch System are the agency's first major components for establishing a human presence in deep space," the agency wrote in its announcement. "With these transportation systems progressing toward their maiden flight in 2018, NASA now is looking toward investments in deep space habitation — the next major component of human space exploration beyond low-Earth orbit."

Successful proposals will include plans "for an evolvable approach to long-duration deep space habitation and the development of full-size, ground prototype habitat units no later than 2018," NASA said.

Applicants from U.S. companies, universities, and nonprofits can submit their proposals electronically by 5 p.m. ET on June 15. Interested parties will have an opportunity to ask NASA questions about what it's looking for during a meeting at 11 a.m. on Monday, April 25.

The solicitation comes after the agency in October 2014 first requested industry proposals "for concept studies and technology development projects in the areas of habitation, advanced propulsion and small satellites" as part of its Next Space Technologies for Exploration Partnerships (NextSTEP) program. Now, with phase 2 of the program, NASA is providing an opportunity for additional contractors to join the party.

"NASA is increasingly embracing public-private partnerships to expand capabilities, and opportunities in space," Jason Crusan, director of the space agency's Advanced Exploration Systems Division, which sponsors NextSTEP, said in a statement. "Our NextSTEP partners commit their own corporate resources toward the development — making them a true partner in the spaceflight economy."
