December 27, 2024 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.
- Chart showing total mass put in orbit in 2024 by various companies and nations
Not surprisingly, SpaceX has launched more mass than everyone else combined.
- Air & Space touts the navigational work done by Jim Lovell during Apollo 8 in 1968
For most of the mission, Lovell’s work was merely a back-up to calculations provided by ground computers and plugged into the capsule computer for use with its inertial measuring unit (IMU). Only once was Lovell’s navigation necessary, when he accidentally rebooted the IMU so it thought it was on the launchpad, not on its way back to Earth. To reprogram it he had to do his sextant sightings and enter those numbers into the computer.
- On this day in 1984 the Martian meteorite that scientists later claimed carried evidence of microscopic life was collected on the Antarctica ice cap
Other scientists later challenged the claim, and today it is generally dismissed.
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.
3. A Paypal Donation or subscription:
4. Donate by check, payable to Robert Zimmerman and mailed to

Just to clarify: That was just the graph of the upmass in the third quarter of 2024.
BryceTech does these little reports every quarter. Great stuff! Completely free to download. Worth bookmarking their page.

But for each of the first three quarters this year, you can see that SpaceX has been consistently launching 9 to 10 times as much as the rest of the world put together.
What will happen in 2025? Elon wants to launch 180 times. OTOH, New Glenn, Ariane 6, Vulcan, MLV, and Neutron are coming online in 2025, along with Zhuque-3 and Hyperbola-3 in China….but on the gripping hand, Starship may actually start launching Starlinks this year. All we can be sure of is that 2025’s aggregate stats will shatter 2024’s.
