As GeekMom’s token meteorologist AND military member, in honor of the final shuttle mission planned for next week, I’m thrilled to share with you some insight into the weather forecast preparations for a space shuttle launch.
After all, what delays launches most often? The weather, right? I’m not sure if a precise count exists, but according to HowStuffWorks, weather and mechanical delays dominate total delays, and many have guessed it’s about a 50/50 split.
For anyone who has tried to center a road trip to Cape Canaveral around a launch, only to have that launch delayed so much you effectively wasted a trip, you might appreciate the precision involved here.
Kathy Winters is the Shuttle Launch Weather Officer with the U.S. Air Force’s 45th Weather Squadron at Cape Canaveral Air Force Station, Florida. The 45th is charged with the official go/no go launch weather forecast for all Space Shuttle missions. Ms. Winters wrote a series for the U.S. Department of Defense’s Armed with Science blog last April, walking readers real-time through a launch forecast process for the (originally scheduled) 29 April Endeavor launch.
Enjoy these blog posts as Ms. Winters walks you through the wide variety of forecast support required for a successful mission:
Forecasting for Moving Solid Rocket Booster Segment
Forecasting for Moving the External Tank Barge
First Launch Forecast (issued approximately 3 days prior to scheduled launch)
How Rockets Can Trigger Lightning
Brush Fire at L-2 Days & Forecasting for the Solid Rocket Booster Recovery Team
The Launch Day Forecast! (this post was scheduled to run on the original launch date: 29 April, however the launch didn’t actually occur until 16 May, due to mechanical delays)
I’d venture that this aritlce has saved me more time than any other.
