Apollo 15 blasts off with an all-Air Force crew: Col. David R. Scott, Lt. Col. James B. Irwin, and Maj. Alfred M. Worden. The mission is described as the most scientifically important and, potentially, the most perilous lunar trip since the first landing. Millions of viewers throughout the world watch as color- TV cameras cover Scott and Irwin exploring the lunar surface using a moon rover vehicle for the first time.
Air Force Gen. Alexus G. Grynkewich assumed command of U.S. European Command on July 1, taking over the key assignment as the U.S. and its allies contend with a resurgent Russia and a grinding war in Ukraine.
