Space telescope “Hubble”, named after one of the most influential astronomers of the twentieth century, Edwin Hubble, was launched into orbit by the space Shuttle Discovery on 24 April 1990. It is a joint project of NASA and the European space Agency and is currently at the height of 569 kilometers. Due to its unique location, the 2.4-meter mirror telescope gives us an unprecedented window into the Universe for almost 30 years.For example, recently, the telescope has shown us 265, 000 galaxies in one photo. The use of the telescope is invaluable, but do you know how long it will last in space?
How much time “living” space telescopes?
As the portal astronomy.comthe best friend of every astronomer on the planet — the Hubble telescope — it’s getting ready to retire. In that case, if the telescope is not going to happen any unexpected trouble that can make the basic tools of the instrument, the telescope will continue its work until 30 June 2021. To this date, NASA officially financed all its operations, or otherwise associated with the space telescope.
However, due to the fact that the Hubble telescope is in the border zone between Earth’s atmosphere and near-earth orbit, the device is experiencing some resistance or friction from particles in the air when it rotates around the Earth. If NASA decides for some reason to extend the Hubble mission in 2021, the device, in the end, everything would crash to the Ground by the middle of 2030-ies, regardless of the operational state of the telescope.
Despite the fact that currently most of the tools telescope operating at full capacity, solid space age device now begins to come into its own. So, some parts of the Hubble is no longer functioning properly, and the data received by the device, need further processing to ensure the accuracy of the data obtained. However, even considering such limitations, experts recognized that the telescope remains an invaluable asset to science.
The importance for humanity of the Hubble space telescope is unlikely to disappear any time soon. Primarily, this is due to the fact that the space telescope James Webb, also developed by NASA, is a direct successor to Hubble. In fact, these two telescopes are actually complementary, because if the Hubble has a limited capacity in the near-infrared wavelengths, the telescope James Webb is ideally suited to study such phenomena as the formation of stars and planets, extremely distant galaxies and even of the atmosphere of exoplanets, which are best visible in the infrared range. However, Hubble is best suited for observations in ultraviolet and optical bands of the light spectrum, and because the Earth’s atmosphere blocks most ultraviolet rays, Hubble can see things that will never be able to see the telescope James Webb.
