The World's Largest University
​Rocket Engineering Competition

What we do

ESRA hosts an International Rocket Engineering Competition (IREC) for student rocketry teams from across the USA and around the world. With a minimum payload size of 2.2 pounds and target altitudes of either 10,000, 30,000 or 45,000 feet above ground level. Competing rockets are typically 4 to 8 inches in diameter and 8 to 20 ft. long. Multistage rockets and all chemical propulsion types (solid, liquid, and hybrid) are allowed.

​Beginning in 2025, the IREC will be hosted at ​Spaceport Midland, Texas

Brief History

Picture
Since 2006, the IREC was an annual occurrence in Green River, UT. The competition achieved international status in 2011 – when schools from Canada and Brazil joined – and has doubled in size every year since 2013. By 2014 we were the world’s largest rocket competition at the college and university level. 


More than 600 students participated in the 2016 competition, representing over 50 schools from 6 different continents. It was at this point a new venue became necessary if the IREC was to continue grow and thrive. With the world class facilities and assistance of expert staff at Spaceport America, NM, we took the IREC to a whole new level!

Beginning in 2025, the IREC will be growing into a new launch site, Spaceport Midland, Texas, to provide even more exciting challenges for the student teams.  ESRA has introduced the 30k and 45k 2-stage categories and are looking forward to an even brighter future for student engineers!

Why We Do it

Picture
Designing, building, and flying research rockets is a great way to motivate and encourage students to pursue science, technology, engineering, and math (STEM) based careers. The smoke-and-fire, noise, high speeds, and sleek aerodynamics of rocketry draw student interest in STEM like few other fields can.

​They have "Rocket Fever!", and competition motivates them to extend themselves beyond the classroom to design and build these high flying machines themselves. These students also learn to work as a team, solving real world problems under the same pressures of cost, schedule, and technical risk they'll experience in their future careers.

Judging Criteria Overview

  • Technical poster and podium sessions before an expert judges panel during a conference day
  • Written technical report on their project concept, requirements, design implementation, and testing
  • Written technical report appendices on safety analysis, including hazard & risk assessments
  • Quality and competency of final design implentation
  • Amount of student researched & developed systems, versus off-the-shelf components
  • Rocket flight performance measured by distance from target altitude and successful recovery
  • Payload innovation and functionality 
  • Professional conduct and use of procedures
