COSROCS does a huge amount of educational work! Dozens of young potential rocket scientists build their first model at the annual Cool Science Carnival at UCCS.

Video of the ULA interns' Future flight at Chiliblaster/ULA/Ball launch on 7/18/15. This is a HUGE O-class rocket, with many payloads.

COSROCS Needs Volunteers!!

   We are very proud of the strong community following that we have built
   over the past fifteen years! We support dozens of requests for educational
   STEM outreach every year, and fulfill these requests strictly through a
   volunteer 'Pay It Forward' attitude. We love rocketry, and we also
   strongly believe in rocketry as an excellent STEM educational activity.

   However, COSROCS is in crisis! Our dedicated team is both aging and dwindling.
   We are down to FIVE core members, and two of them are now 80 years old!
   We desperately need new volunteers to help with our activities.

   So if you love rocketry, and love sharing rocketry with kids and community,
   PLEASE consider joining us and helping to support our mission.

   THANK YOU!!

COSROCS Trailer Theft

   Just a reminder that our club equipment trailer was stolen on 26 May 2024.
   This is becoming old news, but it deserves to stay in our memories;
   please stay on the lookout for our old trailer and any lost equipment. Thanks!

   We have recovered very well from this loss, thanks to very generous
   community support - Over 25 donors contributed a total of $3200
   to help with our equipment replacement costs.

   A very special THANK YOU to the Lance P Sijan Chapter of the
   Air and Space Forces Association for fully funding our new trailer!

   Go here for full details of the theft.
