NASA is going back to the Moon! To enable astronauts to stay on the lunar surface for long periods, they need new infrastructure, habitats, and systems to support increasingly ambitious missions. Learning to build this infrastructure from lunar resources is important. Can your students help tackle this challenge?

Competition Process

Develop your own regolith concrete mixture and design your lunar habitat! The lunar surface is covered with a fine-grained rocky material called regolith. We can use this material to help build the infrastructure needed for future missions. This process is called In Situ Resource Utilization (ISRU). In this challenge, you will get hands-on with a lunar regolith simulant engineered in the lab to mimic the properties of regolith found on the Moon. A Program Guide walks you through a series of activities to learn about the properties of lunar regolith, use it to develop a concrete mixture, test your concrete's strength, and use what you have learned to design a lunar habitat for future long-duration missions to the surface of the Moon!

Judging Criteria

Rubric provided in the Project Guide on Page 18.  For each photo or file that you upload, please label it in the following manner to help the BTMC keep all files sorted: TeamName.State.PhotoMidpoint1, or  TeamName.State.PhotoMidpoint2, or TeamName.State.concretedevelopment etc. Example:
  • If my team, who are the Buccaneers, was turning in a photo of what we have been working on we would label it as: Buccaneers.NM.PhotoMidpoint1
  • If my team was turning in a 1-2 page document with the recipes that we used for our bricks, we would label it as: Buccaneers.NM.Recipe Document

Awards & Recognition
