BBQ Lunch to Benefit TARC Team

Posted: April 20, 2021

At the next launch, Saturday, April 24th, in Hutchinson, KS, there will be a BBQ lunch available. The menu will include pulled pork, baked beans, chips, and brownies. Cost will be $10 for adults, $5 for kids. All proceeds will benefit the Wichita team participating in The American Rocketry Challenge (TARC). So fly some rockets and eat some lunch.

First Launch of the Season In the Books (finally)

Posted: April 12, 2021

After two postponements, we finally were able to enjoy the first KOSMO launch of 2021 on Saturday, April 12th. Even so, the plans ended up changing at the last minute, opting for a low power launch in Hutchinson rather than a high power launch in Ellinwood due to recent rains. The day was a bit breezy, but we managed to conduct 59 launches and kept them all on the field.

We have decided to go slightly off schedule and hold another launch in Hutchinson on Saturday April 24th. This again will be only for low-mid power rockets. Come join us for more rocketry fun.

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.
