Northern Colorado Rocketry
2021-04-03 Pawnee Open

North Site - Pawnee Grasslands

Saturday April 3rd, 2021

Launch Summary

Secretly named the Count Down launch (4-3-21) Our Pawnee Open can only be described as Epic.  Huge thanks to Jack Matthews for towing out the equipment trailer early in the day and then for doing much of the range set up, with help from Scott Dukes and David Pinter and Jesse Frey and am sure I'm forgetting others. We slowly orgainized and got everything ready for an early start on Saturday.  Waiver went from 8 AM till 6 PM.  So great to be back out on the range with so many rocketry family friends.  

Weather Conditions

In a word - stupendous.  A quiet chill Friday night warmed to a glorious clear day on the prairie, with temperatures reaching into the seventies and just a hint of a breeze.  Clear sky at night with a -3.8 magnitude visible pass of the ISS.
