Official announcement/confirmation on the timeline for upcoming deep space exploration missions:
– Tianwen-2 asteroid sample return mission will launch in 2025.
– Tianwen-3 Mars sample return mission will launch in 2028.
– Tianwen-4 Jupiter probe will launch around 2030.

Separately, China has confirmed that Chang'e-7 and -8 missions will be launched in 2026 and 2028, respectively.

The first 40-meter-diameter radio telescope is already under construction.

The VLEO satellite has started its decent from an initial orbit altitude of ~531 km. CASIC Chutian-001 is the first of a planned constellation of 300 satellites. Note that on July 22, 2023, a satellite of a similar purpose, Qiankun-1, from C-SPACE was launched into an orbit at an altitude of 485 km; it is now at altitude of 166 km. CAST Shiyan-25 is also testing new earth observation technologies in a VLEO; launched at an altitude of 320km now at 285km.

UPDATE
SY-25 exceeded 1 year at an altitude of 271 km
Qiankun-1 (57422) remained at an altitude of 333 km since Mar 2024.
Chutian-001 (59811) descent rate accelerated and is now decreasing in altitude 5 km per day

Interesting video about Chinese megaconstellations. Satellite manufacturing looking like the biggest bottleneck right now, of course launch capacity - both rockets and launchpads - is an issue as well:

Interesting video about Chinese megaconstellations. Satellite manufacturing looking like the biggest bottleneck right now, of course launch capacity - both rockets and launchpads - is an issue as well:

they are building many new space launchpads. in the future, they can launch 2-3 rockets per day rather than 1 rocket in every other day.

if they build satellites like they build EV cars, then it shouldnt be a problem .

A Long March 2D has successfully launched Shijian-19 (实践十九号卫星), China's first reusable satellite. Shijian-19 will be used to verify key technologies for reusable satellites. It also carries plant seeds for experiments and scientific payloads from several countries including Thailand and Pakistan. This launch marks the 537th launch of the Long March series.
