NASA is offering $35,000 (£28,000) in prizes to anyone who designs a toilet that can be used on the Moon.
The famous space agency has set its sights on the Moon once more with the organisation eying a 2024 visit to the lunar surface.
But NASA also appears to have its thoughts in the gutter as well, with officials pointing out bathroom breaks will be vital for its Moon-bound astronauts.
It said the new loo would need to work in the micro-gravity of space and on the Moon itself where it is about a sixth of that on Earth.
The mission will also include the first woman astronaut to travel to the Moon, so the toilets need to be able to accommodate both men and women.
In its instructions, NASA said the design should conserve water and “help maintain a pristine environment inside the lander that is free of doors and other containments”.
The guidelines continued: “Bonus points will be awarded to designs that can capture vomit without requiring the crew member to put his/her head in the toilet.”
It should also be able to support a crew of two astronauts for 14 days and allow for waste to be disposed outside the vehicle.
Further instructions said the toilet should be easy to clean and use less than 70 watts of power while also making less noise than an average bathroom fan.
The top prize is worth £16,196, while the second is worth £8,000 and third place will pocket £4,000.
While NASA is first looking to send people to the Moon within the decade, the space organisation is also planning to fire a mission to Mars.
Experts believe the Red Planet can also be a viable colony for mankind with one study estimating only 110 people would be needed to start an independent colony.
The jaw-dropping conclusion was found in a study carried out by Professor Jean-Marc Salotti at France’s Bordeaux Institut National Polytechnique.
According to Dr Salotti, the colony would need to live in an oxygen-filled dome and start farming if they were to carry on living on the planet.
He even made the prediction after he used a model to determine the “feasibility of survival on another planet”.
