Our Competition

The StellarXplorers National Space Design Competition requires an adult to register as a Team Director before any students are permitted to compete. Having only one adult Team Director of record for each team is a non-negotiable requirement. An adult may serve as Team Director for up to five teams and is responsible for the proper supervision of all their teams during all competition-related activities. The Team Directors retain the authority and responsibility to control their teams, including access to other people. The Team Director is the ultimate authority concerning who works with their team. A Team Director may assist other teams only as a registered Mentor or Team Assistant.

STLX IX Finals is planned to be in-person, and it will tentatively be hosted at Space Center Houston, TX.

Before proceeding to the StellarXplorers portal for STLX IX, we ask that you take a moment to fully review the contents of this page, especially the instructions on how to navigate our registration system. Team directors, regardless of previous participation in the competition, you will need to create a StellarXplorers Portal account to proceed with registration.

Team Directors

Team Directors are not required to have prior experience with the competition, nor do Team Directors need to have experience with STK or orbital mechanics to serve in the role. The competition focuses on the problem-solving side of space system design and less on advanced physics or equations.

Team Directors may work with their respective teams during practice rounds, and remain responsible for team’s safety and integrity of the competition during the qualifying rounds, but they may not assist teams in any aspect of preparing their competition responses during the qualifying rounds

Before a Team Director can officially serve in the role, they must be vetted and approved to work with minors by Verification Officials – these are usually school officials or individual supervisors. For more information on the verification process, please review the Rules Book.

Starting up a student organization can be challenging, but it is important to keep your goals realistic and start small. Once you have a strong foundation with one or two teams, you can continue to expand your organization! Since teams are composed of 2 to 6 competitors per team, you do not need many people to get started.
