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.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

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!
