January 2, 2025 Quick space links
Courtesy of BtB’s stringer Jay. This post is also an open thread. I welcome my readers to post any comments or additional links relating to any space issues, even if unrelated to the links below.
- The rough specs of the Chinese Halong re-usable mini-shuttle being built to ferry cargo to the Tiangong-3 space station
It can carry two tons of cargo and stay docked for three months, then return with cargo.
- Chinese pseudo-company Landspace touts completion of nine engines for its Zhuque-3 rocket
The rocket is essentially a copy of the Falcon 9, with a re-usable first stage. The first three launches in ’25 will use an older version, followed by the upgraded re-usable version.
- A detailed survey of the new rockets China will launch in 2025
Most of the rockets are coming from pseudo-companies, with several aiming for re-usability soon thereafter.
- Astronomers now posit that at least one fast radio burst came from the magnetosphere of neutron star
Interesting study, with a lot of uncertainty.
- Eutelsat-OneWeb constellation down for two days, now back in operation
The outage was caused because software did not realize 2024 was a leap year.
Readers!
Please consider supporting my work here at Behind the Black. Your support allows 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. 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. Only now does it appear that Washington might finally 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.
You can support me either by giving a one-time contribution or a regular subscription. There are four ways of doing so:
1. Zelle: This is the only internet method that charges no fees. All you have to do is use the Zelle link at your internet bank and give my name and email address (zimmerman at nasw dot org). What you donate is what I get.
2. Patreon: Go to my website there and pick one of five monthly subscription amounts, or by making a one-time donation.

Re: Leap Year software
I thought we’d seen the last of this sort of thing in the late 90s when so much software had to be rejiggered to handle 4-digit year values. My own experience with Leap Year calcs lies more than a half-century in the past when I was writing a library of calendar arithmetic subroutines for a then-cutting-edge on-line hospital system using assembly language on a Xerox Data Systems Sigma-series mainframe. My stuff way back then apparently worked better than what present-day Europeans can turn out.
“Boeing’s 737 Max Software Outsourced to $9-an-Hour Engineers”
“It remains the mystery at the heart of Boeing Co.’s 737 Max crisis: how a company renowned for meticulous design made seemingly basic software mistakes leading to a pair of deadly crashes. Longtime Boeing engineers say the effort was complicated by a push to outsource work to lower-paid contractors.”
“Increasingly, the iconic American planemaker and its subcontractors have relied on temporary workers making as little as $9 an hour to develop and test software, often from countries lacking a deep background in aerospaceーnotably India.”
