. Space Telescope

SPACE shuttle missions, which last usually one to two weeks, often launch equipment in space, retrieve it, or repair it. In 1990, the space shuttle DiWove/y launched the huge Hubble Space Telescope (HST) into Earth orbit. Called the “new window on the universe,” it was expected to give much clearer pictures of space than ever before because it would be orbiting outside Earth’s atmosphere.

Unfortunately» the first images from the HST were blurred because of a faulty mirror system. After over a year of training, crew in the space shuttle Епдшш(щг took off to repair the telescope in December 1993.

The astronauts worked on the telescope standing on the shuttle’s big robot arm, the Remote Manipulator System. They replaced corrective optical equipment, added a new camera, and other parts. By Januaryi images from the telescope showed the repairs had worked. Пае pictures were clear and spectacular! These images have helped scientists learn much more about the universe.

Space Repairmen

In December 1993, two astronauts of the space shuttle tndpovour repair the Hubble Space Telescope. They work at the end of the shuttle’s robot arm. (he astronauts inserted special mirrors to correct the flaw that had blurred the telescope’s images.

Swirling Galaxies

An image from the repaired Hubble Space Telescope shows the close encounter of two galaxies. The starry pinwheels, galaxy NGC 2207 with a large bright center and galaxy 1C 2163, lie tens of millions of light years away from Earth.
