Last Launch of 2023

Posted: October 11, 2023

KOSMO has had a great year of rocket flying. So far we have been able to hold every scheduled launch, with a few postponements. There is one scheduled launch left and that is coming up on November 11th. This will be our annual "Night Flight" launch. We will start at 2:00pm and go until dark. After dark there will be an opportunity to fly lighted rockets. Come out and enjoy some rocket flying one more time this year.

KOSMO Looking Forward to the 2023 Launch Season

Posted: February 19, 2023

The KOSMO launch schedule has been set for the 2023 season. We will once again start out with SpringFest on March 18th. This is a high-power rocket launch near Ellinwood, KS. Kansas weather in March is rather volitile so we have two alternative dates planned, the first for March 25th, and the second for April 1st. Stay tuned to the web site or our Facebook page for announcements concerning the launch schedule.

Please see the Events Page for the 2023 schedule. If you are interested in coming to one of our launches, take a look at the Spectators and Guests page for information.
