- Next American unmanned lunar mission is Firefly before end of year, landing in early ’25, with Intuitive Machines next attempt launching and landing at about the same time
If both go off as promised the end of the year will be quite interesting.
- Intuitive Machines picks Cobalt-60 as fuel for new spacecraft electrical power source
This appears to be the first time Cobalt-60 has ever been used. From Jay: “It is easy to make Co-60, just bombard iron with neutrons. It happens all the time at nuclear reactors when stray neutrons hit steel, but it has a short half life of five years. It puts outs beta decay, that is what they are using for heat, but the gamma rays it puts out worries me with the electronics. They probably licked that problem or else they would not do it.”
- Vast unveils a new website
Nicely done. Simple and easy to navigate.
- Long March 2F and Shenzhou capsule now at launchpad for eighth manned mission to China’s Tiangong-3 space station
The video provides a lot of visual shots of the rocket, the stacked spacecraft, and the launchpad. The grid fins on what I think is the rocket’s upper stage are most intriguing. That stage takes the capsule into orbit. Is China trying to bring it back to Earth for reuse?
- A picture of Laika, the first dog in space, launched November 3, 1957 on Sputnik 2
The Soviets made no plans to bring her back to Earth, and so she died in space.
On Christmas Eve 1968 three Americans became the first humans to visit another world. What they did to celebrate was unexpected and profound, and will be remembered throughout all human history. Genesis: the Story of Apollo 8, Robert Zimmerman's classic history of humanity's first journey to another world, tells that story, and it is now available as both an ebook and an audiobook, both with a foreword by Valerie Anders and a new introduction by Robert Zimmerman.
The print edition can be purchased at Amazon. from any other book seller, or direct from my ebook publisher, ebookit.
The ebook is available everywhere for $5.99 (before discount) at amazon, or direct from my ebook publisher, ebookit. If you buy it from ebookit you don't support the big tech companies and the author gets a bigger cut much sooner.
The audiobook is also available at all these vendors, and is also free with a 30-day trial membership to Audible.
"Not simply about one mission, [Genesis] is also the history of America's quest for the moon... Zimmerman has done a masterful job of tying disparate events together into a solid account of one of America's greatest human triumphs."--San Antonio Express-News

R-7/Soyuz also uses grid fins–for aborts.
That’s likely the case here too.
N-1 had them at the base.
Some bombs have them.
Here’s Homer Simpson on Co-60

tl;dr he should be dead.
Jeff Wright, you said “N-1 had them at the base.”
Were they movable? The pictures I have seen implied they were hinged at one edge, the edge toward the booster. This might mean they were designed to induce more or less drag as a steering mechanism. Can you elaborate?
Ps. The N1 grid fins in photos I recall seeing seemed to have a much finer grid structure than the SpaceX variety, as if they might actually be for drag. As I recall, some NSF L2 commenters (when I used to be there) asserted that grid fins work by drag, which I disputed.
In other news, ULA began stacking the Vulcan launch vehicle for USSF-106, so they must be at least a little confident that the anomaly investigation for Cert-2 won’t take too long.
I’m honestly starting to feel more optimistic (cautiously optimistic) about VAST’s space station prospects than I am Axiom’s. It feels like a lean, mean operation, trying hard for a first mover advantage. And it is not run by any former government bureaucrats.
Slick website.
Richard M,
Agree about Vast. Their intent seems to be that enunciated by Confederate Gen. Nathan Bedford Forrest – “get there fustest with the mostest.” If Vast can get Haven-1 up in late 2025 or early 2026 and follow up with the initial Haven-2 4-module configuration by 2028, they will have their porchlight lit well before ISS goes into the drink and well in advance of any of their notional competitors.
Also agree about the nature of the Vast organization anent Axiom. Vast has 600 people and are making most of their own stuff – very SpaceX-ish vertical integration. But Vast has a fair number of SpaceX alums on its roster and seems intent on sliding neatly into the Greater SpaceX Space Ecosystem. All the launch services for their station modules will be provided by SpaceX. Thrusters for the Havens Vast is buying from Tom Mueller’s outfit Impulse Space. Those big round windows are probably from an outside supplier too, but I don’t know that for a fact.
Axiom, meanwhile, has had 800 on its payroll and has contracted out the manufacture of most of its hardware. Makes one wonder what all those people do there all day. But Axiom co-founder Mike Suffredini is now out.
There is more than a faint whiff of Rocketplane-Kistler wafting from Axiom I must confess. A management cadre of old NASA hands led by the late George Mueller (no relation to Tom) took over Rp-K from its founders and then proceeded to make a controlled flight into terrain as the NTSB puts it. A key error was abandoning all the work of the original Kistler team and contracting a much more conventional design out to legacy aerospace.
I’d very much like to see Axiom’s station become a thing – and also their lunar EVA suits – but I share your misgivings as to how likely that now is. I hope Axiom manages to Pull Up!, Pull Up!, Pull Up! in time to avoid a crash.

SpaceX alumni would explain why Vast seems to be developing its space station so rapidly. The company got a late start, yet it may be the first in space. They also seem willing to put up a prototype module that will become obsolete within a couple of years. SpaceX did something similar with Starlink. Early satellites that were obsolete on launch allowed them to test reality before sending up its operational version of Starlink, and Vast may be planning a similar tactic for Haven-2.
