Wed, Oct 10, 2018 — This launch has been canceled. This weekend looks to be wet and cold. And while we did have a postpone date of October 20, due to scheduling conflicts, it looks like that will be canceled as well.

Mon, Oct 8, 2018 — The launch originally scheduled for October 6th was postponed due to rain until October 13th. However, forecasts are showing rain being a likely feature of that day as well.

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.
