The quality and caliber of the entries submitted is impressive. But why do scientists need microgravity? Confidence that proposed design will minimize the crew handling of crew waste during maintenance or system use in all mission environments, and will not expose crew to vacuum in the event of a system failure. Include a design concept as both a PDF file and a neutral 3D CAD file, such as: Thoughtfully discuss how your design meets the various specifications listed above and provide supporting sketches, calculations or analysis, Feces (accommodating simultaneous urination and defecation), Please enter your full name and email address. How well does the design address issues like ease of use, odor control, noise, and turnaround time. There's no gravity in orbit and very little gravity on the moon, which raises a question. At the submission deadline, we had received over 2,000 submissions from individuals and teams across the globe. Tell us a little about your background. NASA is already looking at ways to make currently-used space toilets smaller, lighter, and functional in lunar gravity, so your ideas should not be based on current waste management technology. Quality of proposal: clear, concise writing;  thoughtful and complete explanations of how the proposed toilet design concept meets the specifications listed; accompanying CAD file (or other file format) is clear and complete. Microgravity definition, a condition, especially in space orbit, where the force of gravity is so weak that weightlessness results. The g-force is not actually zero in microgravity; it is just very small. The authors of the three most compelling submissions in this category will each win: This challenge will also recognize the top three submissions from the Junior category, one per age group. Submissions must be made in English. Character limits include spaces. 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. The determination of the winners will be made by HeroX based on evaluation by relevant NASA specialists. The European Space Agency is developing an astronaut center in Cologne, Germany, where it will replicate the surface of the moon. Function in both microgravity and lunar gravity, Have a mass of less than 15 Kg in Earth’s gravity, Operate with a noise level less than 60 decibels (no louder than an average bathroom fan), Accommodate users ranging from 58 to 77 inches tall and 107 to 290 lbs in weight, Accommodate simultaneous urination and defecation, Collect up to 1 liter of urine per use, with an average of 6 uses per crew per day, Accommodate 500g of fecal matter per defecation, with an average of 2 uses per crew per day, Accommodate an average of 114g of female menses, per crew per day, Stabilize urine to avoid the generation of gas and particulates, Accommodate crew use of toilet hygiene products, like toilet paper, wipes, and gloves, Be clear of previous user’s urine and feces in preparation for the next use, Allow for transfer of collected waste to storage  and/or provide for external vehicle disposal. Accuracy and availability may vary. Quality of the explanation and supporting evidence for why a solution is designated at a particular maturity level. We know you’re excited to see who the winners are in the Lunar Loo Challenge, and we want to give you the opportunity to hear from them directly when we host the winners’ webinar on October 22nd! Specifically, the contest calls for designs that work in lunar gravity, which is about one-sixth Earth's gravity and microgravity. Lunar toilet design concepts should allow astronauts to urinate and defecate in both microgravity and lunar gravity. You can view the exact date and time for your location in the Timeline here. Help astronauts go back to the Moon in 2024! Why do you believe this could be developed and integrated into a lunar rover in the next 2-3 years? Additionally, toilet designs should conserve water and help maintain a pristine environment inside the lander that is free of odors and other contaminants. Describe how the innovation overcomes limitations and constraints of existing technologies or commercial products. NASA has announced a Lunar Loo Challenge for the public to design a toilet to be used when it sends astronauts back to the moon. Each parabola began with ∼20 s of hyper-gravity (1.8 g) known as the pull-up phase, followed by a partial-gravity or microgravity phase of 32 s (Mars gravity), 25 s (Moon gravity), or 20 s (microgravity).The parabola ended with a second period of hyper-gravity known as the pull-out phase. All challenge-related communication will be in English. Michael Interbartolo, NASA Human Lunar Lander Crew Module SE&I Team, Imelda Stambaugh, NASA Human Lunar Lander Crew System Toilet Lead. No specific qualifications or expertise in the field of waste management  is required. The term ‘Microgravity’ itself is a more confusing term here. So in addition to the main Technical category, this challenge will have a Junior category. As NASA prepares for our return to the Moon, innumerable activities to equip, shelter, and otherwise support future astronauts are underway. The media talking about the space program uses the term “micro gravity” - a misnomer as explained below - for things in orbit around the earth. Register now for the Lunar Loo Challenge - Technical Category Winner Webinar! History. The less confusing term is ‘micro-g’ or ‘micro g-forces’. Designing and developing new lunar toilets may not be as exciting or intriguing as developing tools to support the exploration of the lunar surface, but the need is just as important. NASA encourages outside individuals and non-expert teams to compete and propose new solutions. Please note that additional rankings or judges' scores will not be released. Microgravity research. See more. NASA is looking for a next-generation device that is smaller, more efficient, and capable of working in both microgravity and lunar gravity. Submissions to both categories are due no later than 5pmET on August 17, 2020. We've successfully collaborated winning and fulfilling on NASA contracts through their Center of Excellence for Collaborative Innovation. Defines how often the collections system must be replaced or disposed of in the mission. If you are under 18, please submit to the Junior Category (www.herox.comm/LunarLooJr) or have an adult complete this application on your behalf * (3000 characters), Please discuss in detail how your design will: (i) work in both microgravity and lunar gravity, (ii) accommodate female and male crew, (iii) be easy to use and maintain, with low noise, low odor, and fast turnaround time, (iv) allow for transfer of collected waste to storage or external vehicle disposal (6000 characters), Please discuss in detail how your design will: (i) capture and contain urine, feces, vomit, diarrhea, and menses, (ii) Stabilize urine, (iii) accommodate simultaneous urination and defecation, (iv) accommodate the needs of 2 crew members for 14 days, (v) accommodates the use of toilet hygiene products, (vi) clears previous waste content prior to next use, (vii) defines how often the collections system must be replaced or disposed of in the mission  (6000 characters), Please discuss the safety measures in place to ensure that during nominal use or in the event of a system failure: (i) crew handling of waste materials during maintenance or system use is minimized, (ii) crew members are not exposed to vacuum  (5000 characters), Please discuss the technical maturity of your proposed toilet design.
