Competition

What is the competition?

The StellarXplorers National Space Design Competition is a fun, team building, space system design competition that starts in October and ends in April, where students are challenged to solve orbit planning, satellite component, and launch vehicle selection scenarios presented each round.

FREQUENTLY ASKED QUESTIONS

Team Director:

An adult (e.g. teacher, JROTC instructor, administrator, parent, etc.) approved by a participating organization to act as the administrative lead of a StellarXplorers team. The Team Director (TD) is the main point of contact for competition-related correspondence. A team can only have one director. A Team Director may register up to 5 teams. If a participating organization has more than 5 teams, more than one Team Director will be required. (Minimum age: 18)

Competitors:

Each StellarXplorers team must consist of between two and six competitors enrolled in the participating school or organization.

Technical Mentor(s):

Mentors, also known as Technical Mentors, are optional (but recommended) team technical advisors/subject matter experts. Once registered, a Mentor may be chosen by a Team Director to assist with a StellarXplorers team. Teams are not required to have a Mentor, and Team Directors may act in the combined role of a Team Director and Mentor. (Minimum age: 18)

Team Assistant(s):

Adult volunteers who provide non-technical support and encouragement to the team (assisting with scheduling, set-up, snacks, etc.). Team assistants must register on the CyberPatriot website and pass a background check. (Minimum age: 18)

In StellarXplorers, all participants compete in one division.

Working in partnership with leaders in the U.S. space industry, the StellarXplorers Aerospace STEM Program challenges students toward careers in space or other science, technology, engineering, and mathematics (STEM) disciplines essential to our nation’s future.

  • When participating in the competition, each team is given one scenario during their six-hour competition period (eight-hour competition period for Finals). This includes determining orbits, picking satellite components, and selecting launch vehicles that meet mission requirements throughout the rounds of competition. Each qualifying round is proceeded by a practice round that covers the corresponding tasking. For example, the first practice round consists of selecting orbit characteristics to meet the mission requirements, and the qualifying round covers selecting an orbit but is a little more challenging. Top teams advance to the Semi-Final Round, and the best of the best advance to the in-person National Finals Competition.
  • Please note that Team Directors and Mentors may only assist during practice rounds. During qualifying rounds, it is the responsibility of a designated student competitor to serve as Team Captain and ensure all deliverables are submitted on time.

For more information on the rules, please review the Official StellarXplorers Rules Book:

StellarXplorers is designed for any student, regardless of prior space or orbital mechanics knowledge. Training materials are available through the StellarXplorers website and AGI. Instructions for competition round preparation are emailed directly to coaches prior to each round.

Here are some training materials to get you started:
