Thank you. Google translate tells me that the co-orbiting telescope will be used for astronomy (mostly cosmology). Could not find the diameter though.

I think a previous source said 2.0 meters, so a bit smaller than Hubble.

Btw, this is old news but a nice document that gives an overview of where Chinese comsat bus development was headed, as of 2014

http://worldspaceriskforum.com/2014/wp-content/uploads/2014/05/11C_DISCOVERING-NEW-MISSIONS_YE.pdf
( http://aviationweek.com/awin/china-developing-three-commercial-satellite-buses  )

https://www.forecastinternational.com/news/index.cfm?recno=238415

Component technology wise, this is catching up to US and Europe. First  DFH-4E bus should launch early next year.

China Manned Space Office Advocates 2031-36 Moon Landing

May 2, 2016

The Chinese manned space program proposes to land people on the Moon by 2031-36 as a follow-up to the space station that it will begin launching around 2018.

By setting a target period, the China Manned Space Engineering office is evidently seeking to create an expectation among officials and the public that could help the project gain approval at the top of the government.

“We need to do our best to use the coming 15-20 years to achieve the objective of manned lunar exploration,” Lt. Gen. Zhang Yulin, deputy commander of the manned space program, has told a conference.

There has been research on the further development of the manned space program, Zhang says. “The general view is that manned exploration of the Moon is the choice for raising the development level of the manned space effort, a choice that is in accordance with national conditions and development plans.”

some literature about the SPORT solar polar mission:
http://www.issibj.ac.cn/Publications/Forum_Reports/201404/W020140829517963456181.pdf

Overview of the Solar Polar Orbit Telescope Project for Space Weather Mission
http://www.cjss.ac.cn/EN/abstract/abstract2218.shtml

Quote
The Solar Polar ORbit Telescope (SPORT) project for space weather mission has been under intensive scientific and engineering background studies since it was incorporated into the Chinese Space Science Strategic Pioneer Project in 2011.SPORT is designed to carry a suite of remote-sensing and in-situ instruments to observe Coronal Mass Ejections (CMEs),energetic particles,solar high-latitude magnetism,and the fast solar wind from a polar orbit around the Sun. The first extended view of the polar regions of the Sun and the ecliptic enabled by SPORT will provide a unique opportunity to study CME propagation through the inner heliosphere,and the solar high-latitude magnetism giving rise to eruptions and the fast solar wind.Coordinated observations between SPORT and other spaceborne/ground-based facilities within the International Living With a Star (ILWS) framework can significantly enhance scientific output.SPORT is now competing for official selection and implementation during China's 13th Five-Year Plan period of 2016-2020.
