NASA videos worth a look...

A couple of great NASA videos that hit the site this week, the first I wanted to bring to your attention is one on Sounding Rockets. It explains how they're used and a bit about why they're the right choice for some missions.
Next up is one about Cube Sats, a subject that's near & dear to Dr. Doug's heart, having worked on some.
The last one is from the NASA USLI site, a great introduction video on HP rocketry.
Thanks, and keep building! dr
