(Hubble Space Telescope, HST), is the first space telescope of mankind, with a total length of more than 13 meters and a mass of more than 11 tons. It runs on an orbit about 600 kilometers from the ground on the outer edge of the earth's atmosphere. It orbits the earth approximately every 100 minutes. The Hubble Telescope was launched into orbit in 1990 by the cooperation of NASA and the European Space Agency. The Hubble Telescope is named after the astronomer Edwin Hubble. According to plan, it will be replaced by the James Webb Space Telescope in 2013. The Hubble Telescope’s angular resolution is less than 0.1 second, and 3 to 5 gigabytes of data can be acquired every day.
Because it operates in outer space, the images obtained by the Hubble Telescope are not affected by atmospheric disturbance and refraction, and can obtain images of the infrared spectrum that are usually absorbed by the atmosphere.
Hubble data is analyzed and processed by astronomers and scientists from the Space Telescope Institute. The institute belongs to Johns Hopkins University in Baltimore, Maryland, USA.
The idea of the Hubble Space Telescope dates back to 1946. The telescope was designed in the 1970s and cost about 2 billion US dollars to build and launch. The NASA Marshall Space Flight Center is responsible for the design, development and construction of the Hubble Space Telescope. NASA's Gundam Space Flight Center is responsible for scientific equipment and ground control. PerkinElmer is responsible for manufacturing the lenses, and Lockheed is responsible for building the telescope body.
The telescope was launched with the space shuttle Discovery on April 24, 1990. It was originally scheduled to take off in 1986, but since the Challenger bombing in January of that year, the launch date has been postponed.
The first batch of images sent back to the earth disappointed many people including astronomers. Because of the wrong thickness of the lenses made by PerkinElmer, severe spherical aberration was produced, the images were rather hazy.
