The day the Hubble Space Telescope was taken to space – level 2

24-04-1990

On April 24, 1990, the Hubble Space Telescope was taken to space. The astronauts put it into Earth’s orbit at a height of 600 kilometers. The telescope was designed to take beautiful pictures of stars, planets, and galaxies.

A month later there was a shock. The first test pictures from the telescope were blurred. The quality of the pictures was very bad. The scientists realized that the telescope mirror was done incorrectly. The error was extremely small, but it had a big effect.

The scientists found a way to solve the problem. They decided to put special instruments on the telescope. In December 1993, astronauts put the instruments on the telescope and it began to function correctly.

The telescope was located outside the Earth’s atmosphere, so the pictures were very sharp. Many of them were also very beautiful.

Difficult words: orbit (a way around the Earth in space), blurred (not very clear), realize (to understand), solve (to find a solution).
