The latest infographic on DeepBlue's Nebula-2 reusable launch vehicle.
Nebula-2 has a diameter of 5m. The 1st stage is powered by 11 Thunder-RS LOX/Kerosene engines, and the 2nd stage is powered by a single Thunder-RSV engine. Nebula-2 has a LEO capacity of 25 tons. The Thunder-RS engine has a ground thrust of 1300kN, vacuum thrust of 1500kN, with a thrust range of 40 to 110% and the number of starts of no less than three.
DeepBlue has successfully conducted a partial-system ignition test of the Thunder-RS 130-ton LOX/Kerosene engine.
Just so long as they don't point them directly at the sun and start transmitting...The two 40m-diameter radio telescopes, located at Changhai mountains and Shigatse have been commissioned on the same day. They are now part of the VLBI (Very Long Baseline Interferometry) Network that will help Tianwen-2 navigate to her target next year.

The application process for obtaining Chang'e-6 lunar soil samples is now open to domestic institutions. The application window closes at midnight on November 22 (Beijing time).
The list of domestic institutions that will receive Chang'e-6 lunar soil samples has been released.

A slide on the manned lunar lander. It's mounted on top of a propulsion module that helps it rendezvous and dock with the manned spacecraft (previous slide) in lunar orbit. The lander and propulsion module together weigh 26 tons. The lander itself is equipped with four 7500-Newton engines and can carry two taikonauts + a manned roving vehicle to the lunar surface. The roving vehicle has a 10km range.
An image of the 7,500-Newtonn engine being test fired. It's the same engine used in the landers of Tianwen-1 and Chang'e-3, -4, -5, and -6 missions. Its reliability and performance have been thoroughly proven.

Yet another launch vehicle startup. The name is Beijing ZenkSpace (北京空间致航科技有限公司). Not much is known about the company except the name first appeared in 2019.
Below are images from a presentation given by the company:
– Its first rocket (liquid fuel) will make its maiden flight in 2025.
– A medium and a large launch vehicle are being developed in parallel, covering payload capacities of one to 12 tons (to LEO?).
– The company aims for launch cost of ¥25,000 to ¥30,000 per kilogram.
– The company has a novel reusable rocket design. If I'm reading this correctly, the 1st-stage engines are recovered separately. That is, the entire engine assembly (without the fuel tank) detaches from the rocket, re-enters the atmosphere, and makes a parachute landing.

I didn't catch the joke until I remembered the Sun Probe currently at its closest approach to the sun unless you meant something else, lol.
Not a fan of '3 Body Problem" then.
I didn't pay attention to your original post regarding the lander's engine being "4 X 7500 N" engine. Can you tell me what is the source of this information?An image of the 7,500-Newtonn engine being test fired. It's the same engine used in the landers of Tianwen-1 and Chang'e-3, -4, -5, and -6 missions. Its reliability and performance have been thoroughly proven.

If I recall correctly, it was from a presentation given by the CMS.
