Unfortunately, the RRS has chosen to suspend the 2024 Regeneratively Cooled Engine competition as of June 18th, 2025. We've determined that our designated judges are unable to judge the competition. The Society will review the competition, and we will inform you of when we're able to bring it back.

We express our sincere apologies. Until then, have a blast!

Restroom facility at the RRS MTA is ready

by Dave Nordling, President, RRS.ORG


After a three week testing period, the Reaction Research Society is pleased to announce that the containerized restroom facility is ready for use by our guests and members. Several modifications and improvements were made which have been demonstrated sufficiently. This project has been a few years in the making but well worth the effort.

The electrical, water and sewage systems in both rooms are in working order which means sinks, urinals and flushing toilets are ready for our next event. Some of the interior fixtures are still in work. The interior shower, hot water system and external safety shower are coming soon.

This much-requested and much-desired infrastructure upgrade was built by the hard work of several members over many weekends in all seasons over a couple years. We have many to thank including Dimitri Timohovich, Osvaldo Tarditti, Waldo Stakes, Dave Nordling, Keith Yoerg, Joe Dominguez, Bill Inman, Manuel Marquez, Wilbur Owens and Larry Hoffing,

There’s still more work to go including the floors, shower and hot water system, but we do want to recognize this milestone in our campaign to upgrade our facilities for our membership and our invited guests. Our pit toilet will remain as a backup but many will appreciate a little modern convenience in our remote location.


2022 RRS Constitution Ratified

by Dave Nordling, President, RRS.ORG


The 2022 RRS Constitution has successfully passed a ratification vote as determined by our election chairman, Drew Cortopassi, on 2/1/2023 and confirmed by the executive council on 2/6/2023. The new Constitution takes effect immediately and fully replaces and supersedes all previous versions. The new Constitution will be placed on the new RRS.ORG website when it is launched at the end of this month.

The changes are largely minor with some removal of outdated portions still remaining from past decades. Changes were also made for consistency and to more accurately reflect and define how we operate today. The last revision to the RRS Constitution was over 30 years ago. The arduous review and overhauling process took nearly 4 years since the council first approved the formation of the three member Constitutional Committee which was formed February 2019 and dissolved in January 2022.

I would like to thank all of those who served on the Constitutional Committee and the prior executive councils for their persistence and dedication to this important governing document of our organization.
