China’s first reusable shuttle?
On Monday China launched the first of a new generation of GPS satellites using a secretive new upper stage they call Yuanzheng-1 (“Expedition-1” in English).
The first article describes Yuanzheng-1 as follows:
The Yuanzheng-1 (“Expedition-1″) uses a small thrust 6.5 kN engine burning UDMH/N2O4 with specific impulse at 3092 m/s. The upper stage should be able to conduct two burns and has a 6.5 hour lifetime. It will be adapted for use on the CZ-3A/B/C series mainly for direct MEO/GEO insertion missions (mostly for the navigation satellites of the Beidou GNSS).
This description make it appear that Yuanzheng-1 is nothing more than a typical upper stage, capable of bringing its cargo to the appropriate orbit.
The second article, however, has a concept picture of Yuanzheng-1, a shuttle-like craft that looks to me to strongly resemble the X-37B. Nothing in the second article however contradicts the first, which leaves us with a mystery. Is this upper stage capable of returning to Earth after it deploys its cargo? The fact that the Chinese were unusually secretive about the launch itself suggests that there was definitely something unusual about the rocket itself.
If the Chinese have made their upper stage reusable they have taken a big step to reducing costs in a way that will allow them to compete with SpaceX, should that company succeed in returning its first stage so that it can be reused.
The support of my readers through the years has given me the freedom and ability to analyze objectively the ongoing renaissance in space, as well as the cultural changes -- for good or ill -- that are happening across America. Four years ago, just before the 2020 election I wrote that Joe Biden's mental health was suspect. Only in this year has the propaganda mainstream media decided to recognize that basic fact.
Fourteen years ago I wrote that SLS and Orion were a bad ideas, a waste of money, would be years behind schedule, and better replaced by commercial private enterprise. Even today NASA and Congress refuse to recognize this reality.
In 2020 when the world panicked over COVID I wrote that the 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. Only in the past year have some of our so-called experts in the health field have begun to recognize these facts.
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.
