[1/N] I see that Space.com has picked up the EAST telescope proposed by Peking University.

It is a good opportunity to provide a little background and introduce you to a few groud-based projects in China.

So, what's new?

space.com/china-expandin… [2/N] The exciting part is that, instead of depending on funding from the central government and the CAS system, many universities realized that they could attract private money and build "their own" telescopes.

This is exactly what EAST by PKU is trying to do.

[1/n] Here is a thread about CSST (Chinese Space Station Telescope): A low-orbit, 2-m NUV-optical space telescope focusing on large sky surveys.

It is a separate module of the new space station and planned to launch around 2025. [2/n] The telescope has an off-axis TMA design using SiC mirrors with some "active" capability for in-orbit adjustment.

It has ~1.1 deg^2 FoV for the main sky survey while having four separate small instruments. The designed resolution is around 0.12-0.15 arcsec.
