Thousands of workers, friends and family held a memorial today in Houston say farewell to the seven astronauts who died Saturday morning when the space shuttle Columbia broke up above Texas. Amid memorial speechs, Bush vowed that “America’s space program will go on,” confirming the agency’s resolve to continue space exploration. The memorial ended with the ringing of a Navy bell, once for each astronaut, and then a “missing man” formation of fighter jets.
