Getting back to the Moon by 2024 is an ambitious goal, and NASA is already working on approaches to miniaturize and streamline the existing toilets. As far as I know, there is no difference. No specific qualifications or expertise in the field of waste management  is required. Nonetheless, there are general specifications and constraints for these toilets, and they are discussed below. Getting back to the Moon by 2024 is an ambitious goal, and NASA is already working on approaches to miniaturize and … 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. The toilet design should: We are looking for a design that captures all the functionality of a toilet on Earth. Given that the moon has a gravity 1/6th of earth, would it be possible to enhance or augment this so as to provide close to 1g earth standard for any proposed lunar base? We’re looking for ways to remove sedimentation that regularly accumulates in reservoirs. Successful designs will probably have a Technology Readiness Level (TRL) of 3-5. (pdf, doc, docx). While we are only able to award three winners, we would like to commend and recognize the over 2,000 other submissions that were received. These partners are designing and developing different elements that are part of the overall program, including lunar landers and rovers. Submissions must be made in English. Copyright © 2020 NPR. The Prize is open to anyone age 18 or older participating as an individual or as a team. NPR transcripts are created on a rush deadline by Verb8tm, Inc., an NPR contractor, and produced using a proprietary transcription process developed with NPR. Microgravity definition, a condition, especially in space orbit, where the force of gravity is so weak that weightlessness results. The quality and caliber of the entries submitted is impressive. Additional “mystery” prizes may also be awarded to winners of the Junior category. All challenge-related communication will be in English. Parabolic Maneuvers. These designs may be adapted for use in the Artemis lunar landers that take us back to the Moon. The g-force is not actually zero in microgravity; it is just very small. The winners for the Technical category will be announced on September 30, and the winners for the Junior category will be announced on October 20, 2020. While astronauts are in the cabin and out of their spacesuits, they will need a toilet that has all the same capabilities as ones here on Earth. One downside of using neutral buoyancy to simulate microgravity is the significant amount of drag presented by water. Objects in orbit are not perfectly weightless due to several effects: In Low Earth orbit, the force of gravity decreases by one part per million for every three meter increase in altitude. NASA encourages outside individuals and non-expert teams to compete and propose new solutions. Why do you believe this could be developed and integrated into a lunar rover in the next 2-3 years? 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. At the submission deadline, we had received over 2,000 submissions from individuals and teams across the globe. How easy will it be to adapt the design for integration into a lunar rover. … NASA Needs A Toilet That Works In Microgravity And Lunar Gravity NASA's Lunar Loo Challenge asks the public to design a toilet to be used when astronauts go back to the moon… NASA Centennial Challenges Program, NASA's Human Landing System (HLS) Program, https://www.treasury.gov/resource-center/sanctions/Programs/Pages/Programs.aspx, Recording: Meet the Winners of the Lunar Loo Challenge, Webinar Reminder + Winner Announcement Update. Three different welding processes were tested using a hardware unit called Vulkan. If you are a NASA employee, a Government contractor, or employed by a Government Contractor, your participation in this challenge may be restricted. (5000 characters), Please upload your design files and any supporting documentation here. NASA Needs A Toilet That Works In Microgravity And Lunar Gravity Jun 30, 2020 at 4:00 am By. 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. For the first time, the importance of gravity in amplifying minute oscillatory movements in microgravity into high‐amplitude circumnutations was unequivocally demonstrated. We understand everyone is eagerly awaiting the results so we appreciate your patience! The authoritative record of NPR’s programming is the audio record. Another important update: NASA is excited to promote the winners announcement through their channels and for this reason we'll have to delay the announcement until the following day. There have been some amazing research firsts already. Innovators who are awarded a prize for their submission must agree to grant NASA a royalty free, non-exclusive, irrevocable, world-wide license in all Intellectual Property demonstrated by the winning/awarded submissions. If you were unable to join the webinar, you can watch the recording below to meet the winners, learn more about their solutions, and how they developed them. We want to encourage the next generation of space explorers, engineers, and scientists, and we know that students may think about this design problem without the same constraints as adults. Lunar toilet design concepts should allow astronauts to urinate and defecate in both microgravity and lunar gravity. Winners will now be published October 22nd @ 6am PDT. See the Resource Tab for more information about TRLs. Make sure to register early since space is limited. 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. How were astronauts going to the bathroom before? No late submissions will be accepted. Artemis is NASA’s program to land the first woman and the next man on the Moon by 2024. See the Challenge-Specific Agreement for complete details. Click here to submit to the Junior category. Lunar gravity is approximately one sixth of Earth’s gravity, so urine and feces will fall down. With plans to visit the Moon … Also, we would like to take this moment to send a sincere thank you to everyone who participated in this challenge. History. Lunar gravity is approximately one sixth of Earth’s gravity, so urine and feces will fall down. The less confusing term is ‘micro-g’ or ‘micro g-forces’. The term microgravity is used to describe environments where the force of gravity is present but has a negligible effect. Although space toilets already exist and are in use (at the International Space Station, for example), they are designed for microgravity only.
