Zhongke/CAS Space has successfully completed a static (axial) load test on a Lijian-2 fuselage section. This particular section is 3.35m in diameter and 3.1m in height and is expected to shoulder the highest axial load during launch.

Static load tests have all been successfully completed on the composite 2nd-stage common fuselage section.

The first-stage of Long March 10 will have a reusable version. Land and sea recovery tests have both been carried out using scaled models. In addition to the manned lunar mission, Long March 10 will also be used to carry cargo to the Chinese space station and deploy payloads to LEO.

The first stage of the reusable Long March 10A can be reused 10 times and is powered by seven (YF100N) 130-ton LOX/Kerosene engines. The rocket will be about 67m long, a diameter of 5m, and a take-off mass of 740 tons. Take-off thrust is around 892 tons, and capacity to LEO is ≥14 tons.

A brief summary of the Jilin remote sensing constellation and Changguang, its parent company/operator.

The constellation now has 138 satellites in operation and can revisit any spot 35 to 37 times per day. Changguan has also put into operation phase I of its satellite production base, which occupies 97,300 sqm and has an annual production capacity of 100 satellites.

What is the difference between Gaofen satellites that are part of Jilin Constellation and the Yaogan satellites? Do they all serve the same purpose?

Jilin constellation is purely civilian as far as I know, whereas Yaogan is likely more oriented toward military users.

DeepBlue has successfully completed a final series of hot test runs of Nebula-1's first stage before the upcoming high-altitude VTVL test. The tests verified full flight performance, including high-altitude recovery and variable thrust.

DeepBlue has officially confirmed the high-altitude VTVL test will be carried out in August. Also, the company's Nebula-2 reusable launch vehicle is scheduled to make its first flight at the end of 2025.
