International Rocket Engineering Competition 2025

June 9-14, 2025

Over 2,000 students, faculty and mentors will gather for the 18th annual International Rocket Engineering Competition (IREC)in June of 2025.  Drawn by the opportunity to collaborate and compete in a world class event, you represent the best and brightest from more than 150 colleges and universities located across the USA and around the world. 

Join us as we host thousands of the world's most ambitious collegiate rocketeers in a one-of-a-kind event. Part academic conference and part design-build-fly style competition, the IREC has something to offer students, faculty, industry representatives, and amateur aerospace aficionados alike.

 

The biggest rockets, the highest altitudes and largest payloads! 
​How will you answer the call?

Whether you are an academic, an industry representative, a retired professional, or simply a passionate amateur supportive of young minds who seek new horizons... there are many ways you may become a part of an event impacting the future of aerospace...

As a Sponsor...

You could interact with over 1,800 university STEM students from top ranked universities and colleges in a professional and competitive setting. Not only can your organization interact with them face to face but you can also learn about how their aerospace hardware performs in real world conditions. Finally, you will help make possible an event which inspires the best possible candidates for your company! 

As a Volunteer...

You will join a highly motivated and talented ESRA team which brings together the thousands of moving pieces to build the world's largest collegiate rocket engineering conference and competition. From directing crowds to directing launches and everything in between, we need you at the IREC! 

As a Judge...

You will join a group of respected experts and professionals who interact with the student teams to evaluate and score the deliverables, including technical design documents, overall team performance and launch success.  This team determines who will receive the coveted Genesis Trophy as the Overall Winner of the IREC.

As a Student... 

You will demonstrate your hard work on an international stage, in front of thousands of your peers, professors, and prospective employers. You will engage in design-build-fly style rocket and payload engineering competitions in a professional setting, at world class facilities, where the sky is not the limit!

Important Update from the City of Midland

    We wanted to make you aware of a planned protest scheduled to take place in Centennial Park today, with gatherings expected around 10:00 AM and again at 5:00 PM. This is part of the nationwide “No Kings” protest movement.

      While this event is not affiliated with the Convention Center or any scheduled activities, we have been in contact with the City Parks Department, Midland Police Department, and the Sheriff’s Office to ensure everyone is informed and that necessary precautions are in place. At this time, there are no indications of disruptions to your event. However, we will have additional security on-site throughout the day to ensure the safety and comfort of all guests.

     As a precaution and due to heightened security and the potential for increased foot traffic in the park, the Bush Convention Center will have limited entry points on that day. All entrances will be locked, and all attendees must enter through the Main Street entrance on the east side of the building, located next to the Circle Drive.

We also kindly ask that all attendees wear their name badges while inside the facility for identification and security purposes.

For your convenience, I’ve included a map that shows the closest parking lots, with their entrances marked, as well as the designated entrance to the Bush Convention Center.


Student team volunteer opportunities on Saturday

June 14, 2025, 1 a.m. PDT by ESRA Executive Director

Every year, ESRA has a monumental task of recovering, cleaning and packing up all of the launch operations equipment we use to get your rocket projects launched.

By volunteering to assist, Student teams are eligible for bonus points which could help your overall standing (particularly if you submitted deliverables late) .

 

Student teams are asked to arrived at the LCO area at 10am (with work gloves if possible).  Launch rails will need to be taken down, cleaned and stored.  With some luck and sufficient numbers of volunteers, we can make quick work of this challenging task so we can depart in preparation for the Closing Award ceremony in Midland. 


Saturday Launch Operations Information

June 13, 2025, 9:23 p.m. PDT by ESRA Executive Director

Gates will open at 5am as normal.

There will likely be a 2nd (the last of the IREC) Launch Salvo around 10am.  

Post Flight Data Recovery will CLOSE AT 10AM. NO EXCEPTIONS!    

IREC 2025 Launch Operations, the Airspace and the FAA Waiver close at 12n.  No rocket will be allowed to launch after 12n (even if it is prepped and on the rail).  ESRA will not risk our incredible FAA waiver

Teams who are launching in the first salvo (those in Quarantine now), must recover their rocket and bring it to Post Flight Data Recovery before 10am to receive credit for the flight.  If you arrive after 10am and the Post Flight team collects your data, it is still too late to submit it to the judges. They will not accept it as they have already begun their final deliberations on competition winners.

There will be two additional HeroX updates over the next few hours which are very important.

  • Information for Student teams who wish to assist the ESRA team as we close down the range
  • Important information for attending the 2025 IREC Awards Ceremony Saturday evening.

Friday Launch Updates

June 12, 2025, 6:53 p.m. PDT by ESRA Executive Director

All teams are welcome tomorrow. Gates open at 5am.   Teams who have flown on previous days should do there best to allow other teams who have not flown to have a spot under the big tents.  

Also, our medical team has asked us to remind everyone that water + electrolytes are critical to avoiding heat related injuries. Please be prepared.

Friday is your last full day to fly.  Saturday is a very short half day.  Teams are warned that waiting until Saturday to launch is a very, very bad idea. We cannot promise or guarantee your rocket will be able to launch on Saturday due to the overwhelming demand.  You should Launch on Friday to avoid heartache and frustration. Show up early, and be highly prepared to launch before noon at the latest.

Be safe and see everyone on Friday.

 

 

 


Afternoon Launchsite update.

June 12, 2025, 9:21 a.m. PDT by ESRA Executive Director

All remaining teams who can bring their own shade may now depart for the launch site. Please understand that we have no space remaining under the student tents.  Temperatures are rising rapidly and will exceed 100 degrees today.  Walmart and home depot have canopies for sale so pick one up before heading out.  Flight safety review is open and ejection charge testing is available.
