China's Space Program Thread II

The Qilu (齐鲁) remote-sensing constellation, a joint project between the great city of Jinan and the Chinese Academy of Sciences:
1) Qilu-1 Ku-SAR satellite, the highest resolution is 1m, already lauched;
2) Qilu-2 high-resolution optical satellite, panchromatic/multi-spectral/long-wave infrared resolution 0.7m/1.4m/14m;
3) Qilu-3 wide spectral imaging satellite, resolution 4.6m, swath width 120km.

The entity behind Qilu remote-sensing constellation has recently completed a satellite production line in the great city of Jinan. Named Qilu Satellite Innovation Center, the production line has just passed the necessary acceptance reviews before being formally handed over to end user. The development of the production line was contracted out to CASC's Eighth Academy after an open bid process. In addition to the Qilu facility,

to design and build three other satellite production lines.

The AS-01 SAR remote sensing satellite developed by Sixiang Technology (四象科技). It features a phased array antenna and has sub-meter resolution. It will remote sensing services to China's mining industry. Launch is scheduled for July.

It's been confirmed that Sixiang's AS-01 will be launched together with AS-02 and AS-03 in July. All three are remote-sensing satellites, with AS-02 being and optical satellite and AS-03 being an infrared satellite.

at the Paris Air Show. Ride! Space is like the Uber/DiDi for satellites. The company helps some 250 satellite manufacturers and operators find launch providers to launch their satellites. With this agreement, CAS Space will gain access to international launch opportunities.

The private startup Beijing Arrowhead/Space Epoch (箭元科技公司) is planning to conduct a sea water test of its reusable LOX/Methane XZY-1 rocket. The first stage of the rocket –– encased in stainless steel –– is designed to land in the ocean, to be recovered by a towing vessel. The test will verify the fuselage's resistance to salt water. If all goes well, Arrowhead plans a followup splashdown recovery test.

This is a neat concept. Hope they get it to work.
Getting engines to survive salt water injection is a bitch though.

Besides the salt water, I am more concerned of the impact of engine nozzle on water. The force is very high even if the rocket begins free falling from few meters above the surface after a hovering. Basically the nozzles have the same impact force as the landing legs of Falcon 9.

If the nozzle is inside the body and the chamber there is sealed, the impact of the water can be minimized.

Why tow the rocket? Wouldn't using a
