A poem in this movie
< Do Not Go Gentle into that Good Night >
Do not go gentle into that good night,
不要温和地走进那个良夜，
Old age should burn and rave at close of day;
He was a NASA(美国航空航天局) pilot and also good engineer, but he has to be a farmer.
MuCooper and his daughter find the NASA's base. And the NASA requests Cooper to help their project , which is to save human beings.

This is the spacecraft (太空飞船) where Cooper, Amelia, Doyle, Rommily and TARS will spend many years. It's named "Endurane"
The leader of this mission, Professor(教授) Brand.
Brand says that there is a wormhole(虫洞) near the Saturn (土星), which was created by alien intelligence(外星智慧), namely "They" It should be a guidance for mankind to find new homeland.
First, they go to a planet which is covered by water, named Miller. But they find that the planet is very dangerous. They have been misled(误导) from the beginning. Unfortunately, Doyle is killed by the huge billow(巨浪).
老年应该在日暮时燃烧和咆哮；
Rage, rage against the dying of the
light. 怒斥、怒斥那光明的消逝。
......
