China tests rocket engine for the next Long March 5B launches
China’s state-run press today revealed that a full duration test has been successfully completed of the rocket engine that will be used by the core first stage of the Long March 5B rocket that will launch the next two modules for China’s Tiangong space station.
Developed by the China Aerospace Science and Technology Corporation, the engine is designed for the core stage of the Long March-5 carrier rocket series, which will be used to launch two lab modules of China’s orbiting Tiangong space station this year.
The long-range test, lasting 520 seconds, has verified the reliability of the engine, and there will be more than 20 experimental tasks that the rocket engine will undergo to further test its performance, the company disclosed.
Though this short press release does not say, it implies that this new engine is restartable, something that on previous launches of the Long March 5B was not possible for the core stage. This lack meant that once the core stage lifted and deployed its payload into orbit, it no longer had an engine that could control it. It would within weeks crash to Earth, threatening many habitable areas around the globe. This lack also resulted in a lot of very bad press for China.
If this new engine is restartable, it means that China will be able to de-orbit it in a controlled manner, over the ocean. If so, hallelujah! It means China will finally be honoring its obligations under the Outer Space Treaty.
If not, than China will continue to prove that it is an unreliable and dangerous player on the world stage.
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
