The first few years of the telescope were extremely troubled.


After of years of delays following the Challenger disaster, Hubble eventually made it to orbit only to discovered that there was an error in the mirror, blurring all its images.

Luckily the telescope was always designed to be upgradable.

The first servicing mission in 1993 fixed the misshapen mirror and the telescope was upgraded a further four times.


The final mission to the telescope in 2009 fitted the telescope with new batteries and equipment that should keep the telescope running until 2020.
