This Week in Space 140: University Rocketeers

Many of us flew model rockets as young people, but USC Rocket Propulsion Lab takes amateur rocketry to a whole new level--in this case, 470,000 feet! Meet Dr. Dan Erwin and student Ryan Kraemer, who, along with a very talented team of other undergrads, built and flew Aftershock II, a 14-foot, 330-pound "amateur" rocket that flew out of the Nevada desert and into the record books. It's a fun episode that will leave you wishing that your university had a club that was half this cool!
