01-Hubble's Final Frontier 哈勃的最终领域

Hubble. The iconic telescope that's opened our eyes to the secrets of the universe.

Expanding our understanding about the fate of galaxies. . . And introducing us to massive forces we never even knew existed.

This is Hubble's amazing universe. . . The most celebrated telescope on earth never touches the planet.

Hubble Space Telescope orbits nearly 650 kilometers above the earth, racing around the globe every 97 minutes.

Its powerful mirror sees it all. Soaring star factories where new worlds are made. The violence of exploding stars. And a new light on black holes.

Hubble is the key that has unlocked some of the greatest mysteries of the universe.

But now, the telescope is in danger of being lost forever. Crucial instruments have broken down.

A main camera and light-splitting device called a spectrograph no longer function.

Gyroscopes that keep Hubble properly oriented in space are failing. Worst of all, Hubble is falling.

The 12 ton telescope, as big as a school bus, is slowly spiralling toward the earth.
