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.

Conscious Choice cover

Now available in hardback and paperback as well as ebook!

 

From the press release: In this ground-breaking new history of early America, historian Robert Zimmerman not only exposes the lie behind The New York Times 1619 Project that falsely claims slavery is central to the history of the United States, he also provides profound lessons about the nature of human societies, lessons important for Americans today as well as for all future settlers on Mars and elsewhere in space.

 
Conscious Choice: The origins of slavery in America and why it matters today and for our future in outer space, is a riveting page-turning story that documents how slavery slowly became pervasive in the southern British colonies of North America, colonies founded by a people and culture that not only did not allow slavery but in every way were hostile to the practice.  
Conscious Choice does more however. In telling the tragic history of the Virginia colony and the rise of slavery there, Zimmerman lays out the proper path for creating healthy societies in places like the Moon and Mars.

 

“Zimmerman’s ground-breaking history provides every future generation the basic framework for establishing new societies on other worlds. We would be wise to heed what he says.” —Robert Zubrin, founder of founder of the Mars Society.

 

All editions are available at Amazon, Barnes & Noble, and all book vendors, with the ebook priced at $5.99 before discount. The ebook can also be purchased direct from my ebook publisher, ebookit, in which case you don't support the big tech companies and I get a bigger cut much sooner.
