(5000 characters), Please upload your design files and any supporting documentation here. At a minimum, crew using lunar toilets should not be exposed to vacuum during use, and toilet designs should be able to: Additionally, in the event of a system failure, the toilet designs will ensure that: This challenge has two categories: Technical and Junior. Anything that is very time intensive or complicated to use will generally be less attractive to NASA. Overall technical feasibility of the proposal toilet design. This challenge hopes to attract radically new and different approaches to the problem of human waste capture and containment. Microgravity research. If you are a NASA employee, a Government contractor, or employed by a Government Contractor, your participation in this challenge may be restricted. The process for using proposed toilet designs must be relatively straightforward. We've successfully collaborated winning and fulfilling on NASA contracts through their Center of Excellence for Collaborative Innovation. NASA's Lunar Loo Challenge asks the public to design a … The process for using proposed toilet designs must be relatively straightforward. Defines how often the collections system must be replaced or disposed of in the mission. Microgravity is what is generally considered “zero-g” and is experienced as weightlessness. The media talking about the space program uses the term “micro gravity” - a misnomer as explained below - for things in orbit around the earth. Congratulations again to our winners and to everyone who participated in NASA's Lunar Loo Challenge! The idea is to seek the public’s help to devise a space toilet that can work in both microgravity and lunar gravity. See the Challenge-Specific Agreement for complete details. The g-force is not actually zero in microgravity; it is just very small. The toilet design should: We are looking for a design that captures all the functionality of a toilet on Earth. These astronauts will be eating and drinking, and subsequently urinating and defecating in microgravity and lunar gravity. Good morning. Lunar gravity is approximately one sixth of Earth’s gravity, so urine and feces will fall down. The g-force is not actually zero in microgravity; it is just very small. The top three participants in the Junior category will each receive public recognition and an item of official NASA-logoed merchandise. The lunar lander will take one female and one male astronaut down to the moon's surface. You can register your attendance here. To submit to this category, you must be less than 18 years of age. Help astronauts go back to the Moon in 2024! How were astronauts going to the bathroom before? Microgravity Repose Angles of Lunar Regolith In collaboration with NASA Glenn Research Center, Carthage students developed and carried out experiments to measure the repose angle of lunar regolith simulants in vacuum under lunar gravity conditions aboard NASA’s reduced gravity aircraft. Microgravity is what is generally considered “zero-g” and is experienced as weightlessness. The majority of processes on Earth are influenced in some way by gravity, which means exploiting microgravity environments for research is a clever way to learn more about the way in which the world around us works. Your ideas can help jump-start the space economy. When microgravity (μg) is used as a unit of measure, a specific environment can be characterized as … Accuracy and availability may vary. Help sustain America’s reservoirs. There were many innovative designs and approaches to solving our toilet challenge that made it difficult for our judging panel to select the top 3 winners.
