Apollo 13 the spaceship whose oxygen
tank exploded three-quarters of the
weight of the moon
putting the crews life in serious danger
but by using technology from the distant
past these astronauts managed to find
their way back home
56 hours into the mission Apollo 13
experienced an explosion throwing the
ship way off course the lunar guidance
computer wasn't built to handle the
situation so captain Jim Lovell turned
to his space Sexton a version of a
device used by ship captains since the
1750s the sextant could measure angles
between stars to determine the
spaceships approximate position but when
Lovell looked through the Sexton debris
from the explosion made it impossible to
pick out individual stars Mission
Control improvised and told him to use
the star he could see the Sun thanks to
some old-fashioned engineering Apollo 13
made its way back to earth
