The different NASA countdown clocks - 2009.08.27

We get a lot of questions in the live chat room asking "when is the shuttle going to launch" and confusion when people think it will launch in 20 minutes because that is what they see on the T- clock. This video attempts to explain the difference between the T- and L- clocks and let you know when the heck the shuttle is really going to launch!

I like these new pod casts. Short and to the point.

I've been in space biz for 25+ years and this is the best description of the difference between T-clocks and L-clocks I have ever seen - job well done!

Thanks to Spacevidcast for this great primer.

But all the countdown clocks on the nasa site are T-minus clocks.
