Launch Status

Spring Fling

Sat March 16, 2019

Ellinwood, KS

Current Launch Status — GREEN

Thu, Mar 14, 2019 — After a field inspection, we have determined that we are go for launch this Saturday. It will likely be somewhat muddy, so bring appropriate gear for that. There will also not be any lunch provided, so plan accordingly for that as well.

Mon, Mar 11, 2019 — The weather for Saturday March 16th is looking good for a launch, but there is a lot of rain forecast for earlier in the week. That would make for a very saturated field, so the launch status is "yellow" for now.

Spring Fling

Posted: March 4, 2019

The first launch of 2019 is rapidly approaching. That seems hard to believe, probably because the weather has not yet been at all spring like. The first date of Spring Fling is Sat, March 9. At the time of this writing, it seems that the weather may not cooperate with that schedule. So keep in mind that alternate dates of March 16 and March 23 are also scheduled. Keep watch on this site as any announcements will be posted here.

KOSMO Welcomes 2019

Posted: January 16, 2019

KOSMO kicked off 2019 with its annual business meeting on January 12th at the EAA building on the Jabara Airport in Wichita, KS. We enjoyed a BBQ pulled pork lunch prepared by club member Steve Hamous. Following lunch, we made plans for the new year including the confirmation of club officers, setting a launch schedule, choosing events for KRAMO, and several other items.

The 2019 launch schedule can be found on the Events page. There are three high power launches planned at our launch field near Ellinwood, KS and three low-mid power sport launches at the Kansas State Fair Grounds in Hutchinson, KS.

The 39th annual Kansas Rocket Aero Modeler's Open (KRAMO) will be held in June in Hutchinson, KS. Details of this event can be found on the KRAMO page. This is our annual contest with six interesting competative evnets. It will also be a NAR sanctioned National Rocketry Competition launch. For the first time we are also planning to conduct a night launch during KRAMO on Saturday evening.

We are looking forward to a great year and hope to see you out on the launch field. If you have any questions, please see the Contact page for ways to get in touch.
