Happy April 12! This is also the 150th anniversary of the firing on Fort Sumter, South Carolina, the start of America's Civil Way. Yuri Gagarin's flight seems much more positive. We are at the Humans in Space Symposium at Houston's Galleria. Monday morning we heard from Skylab 1 astronaut Joe Kerwin. Last night was a showing of the Hubble 3D IMAX movie at Houston's Museum of Narural Science hosted by John Grunsfeld. More Yuri's Night celebrations will be held worldwide!
