Closing credits are not rolling in the usual direction (from the lower part of the screen towards the upper), but in reverse. This achieves the effect of camera ascending, rather than descending.
Closing credits begin with a motif of a radio telescope array reminiscent of Contact (1997), a film based on the book by Carl Sagan.
All the planets of the Solar System - plus Pluto and Charon - can be seen during closing credits, along with some of their moons.
Apollo 11, Viking, and Voyager 2 can be glimpsed during closing credits, accompanied by a message describing the mission, along with key mission dates.
At one point "Barsoom" can be seen written on the screen. This is a reference to Edgar Rice Burroughs "A Princess of Mars", of which Carl Sagan was also a fan.
The fictitious star pattern seen near the end of closing credits is the same one featured throughout Contact (1997).
Closing credits end with a written quote from Carl Sagan.
