Lift-off presented in real time, and information about Juno II rocket stages was added to the vintage animation.

Pioneer 4 was an American spin-stabilized unmanned spacecraft launched as part of the Pioneer program on a lunar flyby trajectory and into a heliocentric orbit making it the first probe of the United States to escape from the Earth's gravity.

The probe was cone-shaped, 51 cm high and 23 cm in diameter at its base
It carried a lunar radiation environment experiment using a Geiger–Müller tube detector and a lunar photography experiment.

It passed about 60,000 km of the Moon's surface. However, Pioneer 4 did not come close enough to trigger its photoelectric sensor. It was the only successful lunar probe launched by the U.S. in 12 attempts between 1958 and 1963.
