A SpaceX Falcon 9 rocket launches a Dragon cargo spacecraft with 20 rodents aboard along with over 5,000 pounds of other supplies to resupply the International Space Station at 1:52 a.m. on 21 September 2014 from Space Launch Complex 40 at Cape Canaveral Air Force Station. Thank you again to Bob Bruce and Janice Broda for letting me invade their backyard in the middle of the night. More on the launch at http://www.lunarcabin.com/Rocket_Launches/CRS4.html
