The white-knuckle suspense thriller of Apollo 13's famous near-disaster was only a prelude to darker moments ahead. The launch of the space shuttle programme promised routine trips to earth orbit for many new astronauts, but, just when that promise seemed fulfilled, routine shuttle launches began to bore the public. NASA responded by training a school teacher to fly, in order to teach children lessons from space, but Christa McAuliffe's life was tragically cut short as she and the rest of the crew perished aboard the shuttle Challenger, leading to all missions being halted. Eventually the shuttle returned to orbit, but, after 15 years of successful missions, disaster struck again with the shocking loss of Columbia. It marked the beginning of the end for the space shuttle.
