NASA Aerospace Institute - Day 5: Today we started rocketry lessons and learned about Newton's three Laws of Motion. We made pop rockets, paper rockets and altitude trackers, which made for much silly fun for all!

Aerospace Institute - Days 1 and 2: After a lovely opening banquet to introduce the 30 participants (25 overseas and 5 US educators) and various heads of departments that helped to make this wonderful event possible, we spent our first day learning about aerospace history; including the Mercury, Gemini, Apollo and Space Shuttle programs. After that we toured the Astronaut Hall of Fame and saw many incredible items first-hand. One of the highlights included going in the fantabulous G-Force machine – a simulator much like the one which the astronauts use for training – that allowed us to find out what 4 g’s feels like (see picture of me with the vomit bag used, fortunately, only as a precaution). It was an awesome day to learn about history first hand!
Today’s factoid: When we stand on the earth’s surface we say that we are at 1 g (or 1 “gravity”). The space shuttle starts at 1.g g’s at lift-off, builds to 2.5 g’s in 2 minutes, drops to 0.9 g’s when the solid rocket boosters burnout, and then slowly builds to 3 g’s nearing main engine cutoff…cool!
