For many reasons, mostly political but partly ethical, I do not use Google, Facebook, Twitter. They practice corrupt business policies, while targeting conservative websites for censoring, facts repeatedly confirmed by news stories and by my sense that Facebook has taken action to prevent my readers from recommending Behind the Black to their friends.
 
Thus, I must have your direct support to keep this webpage alive. Not only does the money pay the bills, it gives me the freedom to speak honestly about science and culture, instead of being forced to write it as others demand.

The new colonial movement: The second stage engine for China’s new Long March-8 rocket has successfully passed its engine tests.

Developed by the CASC [China Aerospace Science and Technology Corporation, China’s equivalent to NASA], the Long March-8 rocket is a new type of rocket that uses module design and can be prepared in a short time, making it competitive for commercial launch.

The first stage of the Long March-8 rocket is similar to that of the Long March-7 rocket and the second stage rocket is similar to the third stage of the Long March-3A rocket. It has a payload capacity of 5 tonnes to sun-synchronous orbit and 2.8 tonnes to geostationary transfer orbit.

This payload capacity is about a fourth that of the Falcon 9, but because the weight and size of satellites is shrinking, that smaller capacity might actually be an advantage. There is less need for the larger rockets in the commercial unmanned satellite industry, so for China to build a new smaller rocket that can be launched for less, even though it is not reusable, gives them a route for competing with SpaceX’s reuseability.

They hope to launch 10 to 20 times per year, beginning next year.
