NASA is asking the public, "What do you need to bring, and how do you minimize the need for delivery of future supplies in order to establish a sustained human presence on a planet 140 million miles away from Earth?"

NASA has announced the "Journey to Mars" challenge, according to a press release. It has invited the public to write down their ideas, in detail, for developing the elements of space pioneering necessary to establish a continuous human presence on the Red Planet. This could include shelter, food, water, breathable air, communication, exercise, social interactions and medicine, but participants are encouraged to consider innovative and creative elements beyond these examples.

Participants are asked to describe one or more Mars surface systems or capabilities and operations that are needed to achieve this goal and, to the greatest extent possible, are technically achievable, economically sustainable and minimize reliance on support from Earth. NASA expects to make up to three awards at a minimum of $5,000 each from a total award pool of $15,000.

Given spacecraft limitations on weight and volume - and a minimum 500 days between resupply opportunities - innovative solutions are required for a mission to Mars that is not dependent on Earth for resources.

NASA is seeking technical submissions that describe the development of capabilities and operational events necessary, in both the near- and long-term, to advance this bold journey. Submissions may consist of proposed approaches, capabilities, systems or a set of integrated systems that enable or enhance a sustained human presence on Mars. Solutions should include the assumptions, analysis and data that justify their value. Submissions should include a process to develop, test, implement and operate the system or capability.

Submissions will be judged on relevance, creativity, simplicity, resource efficiency, feasibility, comprehensiveness and scalability.
