Hubble Space Telescope

The Hubble telescope is the worlds first space optical telescope. It is very useful to space scientists as it explores space and gives photographs of our universe 24 hours a day, 365 days a year. It is 13.2 metres long and weighs 11,110 kilograms. It takes 97 minutes to complete one orbit right around the Earth, and travels 28,000 kilometres an hour!!

The Hubble Telescope was launched on the 24th of April, 1990 and is still orbiting Earth today, transmitting around 120 gigabytes of science data every week.

NASA named the Hubble Telescope after an American astronomer, named Edwin P. Hubble, who is credited for providing the basis of the Big Bang Theory, as he confirmed an expanding universe.

It is run off solar power from the sun, as it has two large solar panels. As it travels, light is captured by large mirrors on the telescope, which is then directed into several science instruments, creating photographs of space.

Since launching, it has had a few problems including a flawed mirror shortly after it was launched. There have been four servicing missions to fix issues so far.

The Hubble Space Telescope has helped scientists answer many questions, and has also found information that has lead to more scientific questions. It has been so successful that over 9000 scientific papers have been written on the data that it has collected.
