The United States marked the 30th anniversary on Thursday of the explosion of the space shuttle Challenger with a pledge to remember lost astronauts as it presses on toward Mars.
At the Kennedy Space Center in Florida, where the shuttle blasted off on January 28, 1986, singers in red and blue belted out the Star Spangled Banner for a crowd that included relatives and friends of the seven killed that day.
Six NASA astronauts and Christa McAuliffe - who would have been the first teacher in space - died when the shuttle exploded 73 seconds after liftoff.
