Today, NASA officials say twenty-five years of a unique telescope “Hubble”, through which astronomy has moved far ahead. Recall that the launch of the first space telescope took place back in 1990 on April 24 aboard the shuttle Discovery.
«Hubble” was the undisputed star of all time. Use it to do such images, which earlier and speech could not be.
The primary mirror of the telescope has two hundred and forty centimeters in diameter. His polished within a few tenths of a nanometer super precision instruments. This is the most accurate surface ever created by man. This mirror not only allows you to make detailed images of the planets of the solar system, but it can “see” galaxies that are located at a distance of several million light years from our planet.
For all the time the telescope has made more than a million images, a common “weight” of more than two hundred terabytes. More than fifteen thousand images used in scientific papers and publications.
However, it is worth recalling and unpleasant. For example, “Hubble” is not repaired for many years, as there is no necessary equipment to deliver astronauts to the telescope and to ensure their safety during their stay in the open space. Previously, there was an idea to attract employees MSCs, but the deterioration of relations between the United States and the Russian Federation made to forget about this idea.
