China will have its hubble.In 2024, a space telescope named XUntian (surveying the sky) will be moored at the Chinese space station, the first module should be launched in the coming days.This will directly achieve upgrades, a big advantage compared to Hubble which required special missions for its maintenance and the replacement of components.He will nevertheless be able to keep in orbit independently.

The telescope will have a camera of 2.5 billion pixels and a lens two meters in diameter, a dimension comparable to that of Hubble, but with a 300 -time vision field while keeping the sameresolution.It should thus be able to cover 40 % of the sky in 10 years, indicates the Space site.com.Four associated scientific centers under construction will be responsible for exploiting the observations of the telescope.

This telescope must contribute to the study of matter and black energy, observation of galaxies, or the detection and monitoring of transneptunian objects (which orbit beyond Neptune in the solar system) and asteroidsgeocroisors.It will compete with the new James-Webb space telescope with a 6.5 meter lens but with a longer wavelength (therefore a lower power of resolution with equal mirror size).
