Launch Status

Night Flight

Sat November 10, 2018

Hutchinson, KS

Current Launch Status — RED

Fri, Nov 9, 2018 — Due to weather, it looks like we won't be able to do any rocket launching. But we do plan to meet at the field around 3:30 and then find a place to visit and eat some dinner. Feel free to join us.

Wed, Nov 7, 2018 — The forecast for Sat shows quite a bit of wind. It does taper off some near evening, so there is a chance that we could do some rocket flying. We will be meeting at 3:00 Sat afternoon regardless. If we can launch some rockets, great. If not, then we will decide on another activity.

Rocket-tober Fest a Bust. Get Ready for Nightflight

Posted: October 24, 2018

Unfortunately, the fall weather did not cooperate with the scheduled October launch, called Rocket-tober Fest. We ended up cancelling the event altogether. There is one more KOSMO launch on the 2018 calendar, however. That is Nightflight, to be held on November 10th in Hutchinson at the Kansas State Fairground parking lot. This will be a normal low-mid power sport launch, starting at 3:00pm. At dusk, there will be an opportunity to fly lighted rockets into the night sky. This is an event in which you will want to come watch and participate.

FFFF Success. Rocket-tober Fest Next

The Final Frontier Fun Fly launch had to he postponed to our first alternate date, but on that day we had good weather and a lot of good flights. A highlight was the successful Level 2 high power certification by one of our members. We now look forward to our last high power launch of the year, Rocket-tober Fest on Saturday, October 6th. In the event of unfavorable weather, there are alternates schedules for Oct 13th and Oct 20th. This launch will again be at the Lanterman Farm location. Come join us!

Spring Weather Difficulties

Posted: April 20, 2018

The record dry conditions and the Kansas winds have made scheduling rocket launches difficult this year. The March Spring Fling launch was canceled after three attempts. We finally did get a low-power launch in on April 7th in Hutchinson. It started out as a cold day, but got nicer as the day wore on. The next launch is scheduled for May 5, again in Hutchinson. Here's to fair weather and calm winds.
