SDL Payload Challenge

Picture

Rules & Information

The Utah State University Space Dynamics Laboratory (SDL) has been solving the technical challenges faced by the military, science community, and industry for over 65 years. We provide multi-domain mission solutions with expertise in satellites, sensors and instruments, ground systems and data processing, and advanced autonomous systems.

SDL’s mission includes inspiring, educating, and engaging tomorrow’s workforce through a variety of real-life, hands-on experiences such as ESRA’s International Rocket Engineering Competition (IREC). In addition, SDL employs ~130 college students.

SDL is excited to be involved with IREC and to sponsor the payload portion of the competition. After all, there’s no reason to launch a rocket unless there’s a payload! SDL is offering $2,250 in cash prizes to teams that produce meaningful payloads.

Objective: Encourage participants to create payloads that accomplish a relevant function and provide useful learning opportunities.

​To Enter the SDL Payload Challenge:  Submit an SDL Payload Challenge Entry Form no later than two weeks prior to the start of the event. SDL Payload Challenge Forms are available for download from the IREC Documents & Forms page on the ESRA website; email to: [email protected] 
Awards:
  • 1st Place Payload Award: $1,000
  • 2nd Place Payload Award: $750
  • 3rd Place Payload Award: $500
  • Honorable mentions as warranted (judges discretion)

Judging Criteria (1000 points possible):
  • Scientific or Technical Objective(s) (400 points) 
    • How relevant and well-designed is your scientific or technical objective? 
  • Payload Construction and Overall Professionalism (250 points) 
    • Includes make/buy decisions, craftsmanship, material usage, poster, handouts, reports,
      etc. 
  • Readiness / Turnkey Operation (50 points) 
    • Will the payload interfere with launch operations? Will the payload operate after hours of launch preparation, rail time, heat, waiting for other launches, etc? 
  • Execution of Objective(s) (300 points) 
    • Judges should be informed of results by Saturday at noon or a zero in this category will be assessed. 
    • How well did it accomplish the objective(s)? 
    • Note: That rocket failure results in 150 points (half credit – don’t know if payload would have worked or not) 

SDL Technology Relevance Award 
  • This is a separate award and has no impact on the overall SDL payload challenge. • This provides an opportunity for students to focus on and integrate technologies relevant to SDL's  mission into their payload.  
  • ​2025 technology areas: Robotics, Artificial Intelligence, and Infrared
