Looking Forward to the 2021 Rocket Launching Season

Posted: February 21, 2021

Spring is right around the corner which signals the start of the KOSMO rocket launching season. The launch schedule has been posted (see the Launch Dates link in the left column). We will start off, on March 13th with a high power launch near Ellinwood, KS on the Lanterman Family Farm (see the Launch Sites link in the left column for directions). Kansas weather in March is often quite variable, so we do have a couple of alternative dates set aside in case of bad weather. The first of those will be March 27th and the second is April 10th. As always, watch this page or Facebook for last minute updates. As we do at all launches, we welcome new flyers and spectators. Come out and join the fun.
