Every industry has its fan. No different than gear heads, railroad foamers,

All I heard was "FRNs"

Opening the path to the lunar surface

“We have to find a common orbit. We have to find a common launch opportunity, and orchestrating a launch of an SLS and two HLS’s will be some kind of feat,” said Kent Chojnacki, HLS deputy program manager, in an interview before the Artemis 2 launch. “So, we’re working on what the art of the possible is there.”

That would need to be done on a tight timeframe. Chojnacki said he had been instructed to prepare for an Artemis 3 launch no earlier than March 2027 and no later than June.

The landers, he said, would not have to be the full versions needed for a lunar landing: the landers would not need landing gear or the guidance, navigation and control systems needed for landing.

“We asked for ideas ranging anywhere from doing proximity operations,” he said, similar to what took place on Artemis 2 where Orion flew around the SLS upper stage, “all the way to a docking with a crew cabin, where you can cross the hatch and do operations within the common atmosphere.”
 
I am a railfan and railroad modeler & yep foamers exist and are a thing.
As for me, I am fortunate in a twisted sort of way with having endocrine and mitochondrial disease and simply not having energy to expend on foaming.

Here, read this from 2009,

Oh, and have this about that locomotive,
And its road number of 2 is unrelated to the 2 in its type designation.
NOTE to the airplane foamers, EMD locomotive designations do not use a dash like aircraft designations.
Its BL2 instead of BL-2

What Happens Next For Artemis? Can NASA Launch Artemis III Next Year?

With the Artemis II mission successfully completed NASA has set itself a high bar to prepare Artemis III to fly next year, at least it's a high bar compared to the 3 years between flights 1 and 2. It has to assemble a rocket, decide on the mission and then make sure the other parts of the mission are ready for the flight.

Moonbound Episode 1 | Charting the Course

Apr 17, 2026
Artemis II and its test flight around the Moon transformed plans and preparation into execution and exploration. The first episode of our NASA+ documentary series, "Moonbound," explores how NASA prepared to launch new systems and hardware for lunar exploration for the first time with crew.

Under Artemis, NASA will send astronauts on increasingly difficult missions to explore more of the Moon for scientific discovery, economic benefits, and to build on our foundation for the first crewed missions to Mars.

I was thinking about how lunar lava caves might be put to work if filled with air.

Here, a cute mechanism uses a slip of paper as a governor:

Imagine a system like this....with a cable played out above the lunar surface.

In the past, I suggested two lunarvator cables in an "X" configuration with statites at the ends...
allowing the intersection to rise and fall via tacking.

A flying windlass is at the intersection, dangling a net.

Asteroid hits the net. A massive windstorm generates power and blows dust into corners.

The asteroid/spacecraft slows.

It descends over a huge staple type structure like the St. Louis arch... descending to the surface ever slower.

Do-able?

That could also drag things across the lunar surface using the asteroid as the tractor.

You *cannot* design *any* infrastructure to depend on *random* asteroid hits. Human extraterrestrial settlements *cannot* operate like Venus Fly Traps. But do you mind me asking what recreational substance you might be partaking of tonight? An inquiring mind wants to know...

Casey Handmer owes the Orion guys an apology. I tell you this--there are those who would have cheered if it didn't hold up.

The "Orion Guys" couldn't deliver a heat shield in which NASA had confidence, so they had to change the re-entry profile to a more aggressive and violent one to get through the heating phase faster. Not a great endorsement.

Artemis III will fly with a heat shield with gas permeability, returning to the honeycomb arrangement of Apollo rather than the solid bricks of I/II.
 
This was actually a steeper profile---they avoided the "skip" that one would imagine is more gentle.

Titan Dragonfly testing also surprised a few

"What was very surprising about the study is that, when we changed the gas, the ablation phenomenon behaved in different ways. In a classical air environment where you have oxygen present, the ablation happens in a steady way. The flow around the spacecraft erodes the surface and particles get ejected as a constant stream.

"But, when the oxygen is removed, this phenomenon becomes unsteady. Intermittent bursts of particles are ejected and, at times, the process becomes violent. I've been around ablation research for over 15 years and I've never seen this. We were all really surprised when we first observed this behavior in the tunnel.
"

Who would think hot oxygen would make re-entry better?

The parachutes
The capsule's three-parachute system—responsible for slowing Orion's descent and ensuring a safe landing—was developed with key computational parachute fluid-structure interaction (FSI) analysis from mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa, working alongside NASA Johnson Space Center. Their team was the only group providing computational FSI analysis for the parachute system—work completed in 2013, years before Orion's return to Earth.

That modeling proved essential to solving one of the most complex challenges in spacecraft parachute design: how to ensure the parachute is both large enough to slow the spacecraft to a safe landing speed and free from descent speed oscillations associated with shape instabilities
.

Q&A

Another threat?

For decades, we've relied on a NASA test known as NASA-STD-6001B to screen material flammability for flight. But space is much more complicated than an Earth-bound test provides for. A new paper from researchers at NASA's Glenn Research Center and Johnson Space Center and Case Western Reserve University details a planned mission to test the flammability of materials on the moon's surface—where they expect flame to act much differently than it does here on Earth.

False Dichotomy

Both/and not either/or

Besides, I guessed Gateway was a Mars craft on the sly---the propulsion segment is going that way.

Starship had better work for a lunarvator to be constructed. No ice problems at least.

And now the private space world can use a Constellation asset--you know---the one Obama killed?

Originally built in 2005 for NASA's Constellation Space Exploration Program, the centrifuge was designed to help scientists explore how astronauts respond physiologically to reduced-gravity environments experienced on the moon, and eventually Mars. When the program was canceled in 2009, the facility was disassembled and stored at the NASA Johnson Space Center, where it remained in controlled storage for more than a decade.

This time on Ripley's Believe it or Don't:

"Is it on the ramps? Is it on the ramps? Here, wait" (push)... inaudible cursing during a cracking sound--"dammit Billy! You said you had it! Just blame it on re-entry like we did the last time."

I'm Dan Aykroyd....more NASA secrets revealed, tonight!
