Mission to the Moon - Times in hours ==================================== Time - 0.0 - Mission begins Time = 72.0 - At the moon Time = 73.5 - 1 orbits completed Time = 75.0 - 2 orbits completed Time = 76.5 - 3 orbits completed Time = 78.0 - 4 orbits completed Time = 79.5 - 5 orbits completed Time = 81.0 - 6 orbits completed Time = 82.5 - 7 orbits completed Time = 84.0 - 8 orbits completed Time = 85.5 - 9 orbits completed Time = 87.0 - 10 orbits completed Time = 159.0 - Mission complete.
