Chinese pseudo-company successfully completes rocket hop test
The Chinese pseudo-company Landspace successfully completed a rocket hop flight of its Zhuque-3 prototype hopper yesterday, testing vertical take-off and landing in preparation of recovering and reusing the first stage of its rockets.
The hop itself went to 350 meters and performed a small translation maneuver to the landing pad. The hope is called “ZQ-3 VTVL-1” which refers to “Vertical Takeoff – Vertical Landing”. It uses a single TQ-12 methane engine, which is also used on the current ZQ-2 rocket. The engine can throttle between 50-110% of the normal 80 tons of thrust, giving it a throttle range between 40 and 88 tons. The performed flight went on for roughly 60 seconds. The weight of the hopper is 50.3 tons.
Landpace confirmed the landing precision with 2.4 meters, with a landing speed of 0.75 meters per second, at a pitch angle of roughly 0.14 degrees, and a roll angle of 4.4 degrees. The hopper survived the hop and is already being inspected after the flight.
Video of the hop can be viewed at the link. The hopper is almost identical in concept to SpaceX’s Grasshopper test vehicle used by that company, flying with one engine of the same type used in its operational rocket.
If their test program continues as planned, Landspace hopes to begin flying reuseable stages in 2025, with that first stage capable of flying 20 times.
Of all the pseudo-companies in China, Landspace appears to be the most successful. It not only has an operational orbital rocket, Zhuque-2, that has carried satellites into orbit twice (here and here), it is very close to achieving rocket reuseability competitive with SpaceX.
Readers!
Every February I run a fund-raising drive during my birthday month. This year I celebrate my 72nd birthday, and hope and plan to continue writing and posting on Behind the Black for as long as I am able.
I hope my readers will support this effort. As I did in my November fund-raising drive, I am offering autographed copies of my books for large donations. Donate $250 and you can have a choice of the hardback of either Genesis: the Story of Apollo 8 or Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space. Donate $200 and you can get an autographed paperback copy of either. IMPORTANT! If you donate enough to get a book, please email me separately to tell me which book you want and the address to mail it to.
Please consider supporting my work here at Behind the Black. My analysis of space, politics, and culture, taken from the perspective of an historian, is almost always on the money and ahead of the game. For example, in 2020 I correctly predicted that the COVID panic was unnecessary, that the virus was apparently simply a variation of the flu, that masks were not simply pointless but if worn incorrectly were a health threat, that the lockdowns were a disaster and did nothing to stop the spread of COVID. Every one of those 2020 conclusions has turned out right.
Your help allows me to do this kind of intelligent analysis. I take no advertising or sponsors, so my reporting isn't influenced by donations by established space or drug companies. Instead, I rely entirely on donations and subscriptions from my readers, which gives me the freedom to write what I think, unencumbered by outside influences.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Every time I read about chinese space progress I think about how William Jefferson Blythe sold out his country.
More troublesome

The Chinese economy continues to collapse. Don’t worry, their solution is to print more money just like the U.S.
So far so good!
