For those of you who expressed interest in the American Rocketry Contest at today's launch, here's a link to the NAR webpage that is a great place to start learning: https://www.nar.org/content.aspx?page_id=22&club_id=114127&module_id=668278
If that link is broken, just go to the NAR website and click on the "Competition" and "American Rocketry Contest" tabs.
I, and a few other CMASS members, are currently registered as ARC Mentors. We can answer your questions and help you get started.
