At the end of 2023, China plans to launch its first large space telescope, which will focus on the properties of dark matter and dark energy, the formation and evolution of distant galaxies, and many other things. The telescope will also be in orbit with China's space station, and may interact periodically with it for repair or modernization.
There will soon be a new observatory in space.
China has been working for several years on the development of the first large optical and ultraviolet space observatory, called Suntian, which will have a two-metre diameter lens, which makes it comparable to the honorary Hubble, but although the resolution of this Chinese telescope will be similar, its field of view will be about 350 times larger, which means that Suntian will be able to observe much larger parts of the sky.
"," explains Lee Ran, who is working on the telescope, and Hubble's field of vision is about one percent of the size of the fingernail at arm length, so this observatory, although 30 years old, has seen only a tiny part of the sky.
In addition to the 2.5 billion Pixel resolution camera, the observatory will be equipped with four additional tools to map the star-forming regions of the Milky Way, detect rapidly moving objects such as comets and asteroids, study supermassive black holes and direct image of the exoplanet.
Until 2035, Suntian will be the largest space telescope for astronomy in near-violet and visible areas.
Coupled with a Chinese station.
The telescope will operate in an orbit similar to that of the new Tiangun space station, which will allow it to dock with the outpost for repair, maintenance or modernization. China expects to complete the construction of the orbital complex by the end of this year, which will open the way for the launch of the space telescope a year later.
Note that the observatory was originally designed to be installed directly at the space station, and as a result, researchers identified several deficiencies, not the last of which were vibration problems, potential contamination, scattered light, and an obstacle to the station's direct visibility.
