Just few weeks ago, we managed to produce our first multi-hexagons assembled surface.

100% ISRU! No additive been used. Just lunar regolith (as LHS-1 simulant) and electricity.

I think we found the way to make moon surface more enjoyable for Anakin.

One of the questions I get most often when I show people Project Paveway’s hex tile sample is: How much heat can it take?

Today, we tested it with a one-minute propane torch burn.

At around 45 seconds, the center of tile started glowing red hot — beyond what the Fluke 62 MAX thermometer can measure, meaning it had exceeded 500°C.

That’s the kind of thermal performance you need for a lunar landing pad.

Good looking, dimension accurate, 3D printed parts always give me smile.

PA6-GF30 from @3dxtech printed on @Prusa3D CORE One, ready to be assembled into new testing device for the lunar landing pad~

(Yes I know PA6 is no good for vacuum. It's "testing" device)

It’s a pleasure to pitch at ROCKET PITCH NIGHT TOKYO: Bloom 2026. It helps me connected with new partners, getting critical feedbacks to my moonshot plan.

Major decision been made in last few days thanks to the event, to accelerate the progress of Project Paveway. Stay tuned for the news!

Next Thursday, Apr23, I will be pitching [Building Landing Pad and Road on the Moon] at [ROCKET PITCH NIGHT TOKYO: Bloom 2026], under category #4 around 19:00 JST.

If you are in Tokyo, come! Love to see you in-person.

Taping Kapton tape, with gloves on, can be painful. You almost always need to use tweezer.

So we print our owned tape dispenser designed to be used with tweezer...

Router free upgrade on my first generation Starlink. Thank you @Starlink !

IZUMI SPACE is focusing on lunar surface infrastructure, means we are finding way to build “big” things on the moon. Things use meter as size unit.

A landing pad for SpaceX Starship derivative HLS (Human Landing System) is going to be at least 30x30m size.

Now imaging doing laser with 0.5mm dot size for such big object. We should go bigger dot! Right?

It turns out to be a bad idea.

@paulg @michael_nielsen Based on this, radiator as 1/4 size of solar panel...

Radiator is probably operating at ~450K temperature range, ~176C or ~350F.

Double or triple stages heatpump?

Lunar, a world without cement

When I chat with my friends about what IZUMI SPACE is doing (lunar surface infrastructure), the usual first question they ask me is: why not using cement?

The most common cement we use on Earth is Portland cement, which is primarily made by limestone, clay, and some other stuff. Limestone (CaCO3), which is main source of CaO needed in Portland cement, is not available on the moon.

Year-end house cleaning always (re)discover somethings…

1983 “Life in Space”
1987 “F-19 Stealth Fighter”

2 most impactful things in my life. They practically defined who I’m.

This was done over a year ago in 2024. 1085nm DPSSL 10mm dot with @SpaceResTech LHS-1 simulant. Learned lots from this.

@Xaraphim Initiative setup = company guidebook
History context = adapting, fit-in process

Since AI is dealing with non-standard human, it need history context to understand better what this poorly running bio machine want.

At least you can hit delete and start over :)

[Titus Ou @titusou]

@Xaraphim I’m doing something similar but instead of resin model with silcon mold, I use burnaway FDM mold directly.

[Titus Ou @titusou]

@DrPhiltill @thesheetztweetz Blue Ghost's 8 landing thrusters seems making less dramatic effect, compare to single big engine at bottom?

@DJSnM Hi Scott, I made Taiwan mandarin subtitle for you to upload to YouTube. Please DM me.

20+yrs and counting, office and home, highly recommended.

[Titus Ou @titusou]

@Xaraphim Is that ICF203 flange for the gun assembly?

I'd previously test-design a vac chamber using ICF253 pipe, as using mass-manuf parts is cheaper than custom chamber. But it might not be big enough for you.

[Titus Ou @titusou]

@3dxtech I'd learned from trial and error experience how to use PETG+CF, and internal reinforcement skeleton via purposely designed printing modifier really help to stiffen the part.

[Titus Ou @titusou]

XYZ gantry prototype printed with @3dxtech PETG+CF. XYZ carriers in simple plate geometry which was originally designed to be easily fabricated with aluminum, but now I feel I might get away with printed parts.
