Translation of the title

"Dark Blue Space "Nebula-M" 1 "Jump" low-altitude vertical recovery flight test was a complete success."

Press release from Deep Blue Aerospace (in Chinese) http://www.dbaspace.com/newsthing_s.html?n_id=24
Extract
"While Deep Blue Aerospace is conducting a complete analysis of the data of this test, the "Nebula-M" rocket No. 2 test prototype is in the company's assembly plant in Nantong, Jiangsu, and is quickly undergoing assembly and testing. At the same time, the company will continue to implement 100-meter-level low-altitude flight and high-altitude vertical take-off and landing flight tests in 2021. At the same time, Deep Blue Aerospace’s main product "Nebula-1" into orbit rocket has completed the prototype production and strength test of a sub-level rocket body structure last year, and the orbital level launch and vertical recovery test will also be gradually implemented as planned."

Nebula-1 orbital launch vehicle now planned for first flight in 2023:

Deep Blue Aerospace conducts 100-meter VTVL rocket test (https://spacenews.com/deep-blue-aerospace-conducts-100-meter-vtvl-rocket-test/) [dated Oct. 13]

The test is part of the development of the 2.25-meter-diameter Nebula-1 orbital launcher, with a planned first flight in 2023. The Nebula-1 is to be capable of lifting 500 kilograms to a 500-kilometer Sun-synchronous orbit.

So is Nebula-M the test vehicle (not orbital) and Nebula-1 is the 500kg to orbit? Does the larger rocket have an announced name?

And is the first stage VTVL recovery just for the larger rocket or also Nebula-1?

Someone is going to be next to reuse.  Maybe Rocket Lab.  Then China?  Before ULA or Blue Origin or Russia or Europe?

It is expected that this prototype will be retired in order to continue with the full-size prototype which will perform flights of 10 to 100 km.

RL as they have booster just need to refly it.

Is it "normal" the wide oscillation of motor skirt? Do Musk rockets use top-thrusters instead?

Deep Blue Aerospace has conducted 5 ignition tests of its "Thunder-R1" reusable 20-ton thrust liquid oxygen kerosene rocket engine, totalling 138 seconds of burn time. Engine will power the Nebula-1 reusable orbital launcher. mp.weixin.qq.com/s/JzjvAzujpYY7…

through iterative developments in future.  9 of the engines will be used in the 1st stage of orbital class rocket Nebula-1, which is expected to fly in 2023. It will be able to deliver 2000kg payloads to LEO, or 1000kg to 500km SSO.

Following the 1km hop test, DeepBlue completed a series of 5 hot fire tests of its newly developed Thunder-R1 reusable kerolox engine, lasting 4s, 7s, 7s, 30s, 90s respectively. The engine provides 15-tf thrust at sea level, 20tf in vacuum, with a goal of reaching 35-40 tf.....
