What seems like smooth-sailing quickly turns into an emergency for the astronauts of Apollo 13. This clip illustrates a defining moment of the Apollo 13 mission, when the ship experiences critical failures.
The team brainstorms how to get the Apollo 13 crew back to Earth with time to spare even though their spacecraft is running out of power. Aaron suggests that the module conserve its power, and Kranz takes all measures necessary to ensure that they do not lose an American in space.
During the Apollo 15 space mission, astronaut David Scott decides to test Galilleo's theory that all objects fall at the same rate, despite their weight, in the absence of an atmosphere. In his test, he drops two objects with drastically different weights, a hammer and a feather, at the same time.
