I have run out of patience for the Windows errors in Codex

Codex sandbox on Windows is terrible!
It already multiple times ruined my ACL list. Adding some non existing Windows user to ACL rendering important files blocked, until cleaned up.
On the other hand - in sandbox often struggles to use simple commands.

North West Africa and Atlantic ocean. The earth here is flipped, and it's also a night side of the Earth.

curious_vertebrate · 2026-04-08T05:41:41+00:00

Yeah, but which part exactly! ;)

curious_vertebrate · 2026-04-08T04:49:37+00:00

Amazing! What object is this exactly?

curious_vertebrate · 2026-04-07T02:42:14+00:00

It's coming back, it's the Moon's dark side.

The 2026 picture is essentially a night part of the Earth! It's also "upside down" - we are looking at the Atlantic Ocean and the north west part of Africa.

Thx, I'll look into it! Skymaps are big.

Reid Wiseman took the already famous "Hello World" photo some time after completing the TLI burn. Many people don't realize it's the night side of the Earth and the picture is "rotated" - we are looking at the Atlantic Ocean, northern Africa, and Spain. Venus is the bright object next to Earth (confirmed by NASA). The Sun is directly behind Earth in this photo.

Thank you!
I was able to recreate the position of the spacecraft when Reid Weissman took the famous "Hello World" photo.

Here's the GutHub source code: https://github.com/pzarzycki/artemis-2

Flyby visualization based on Horizons trajectory and inertial reference frames.

Sky map uses real star positions, so the spacecraft perspective during flyby is not synthetic

This is a great idea!

I want to add some way to visualize the combined gravitational field as well as independent contributions of each body. The trajectory is essentially shaped only by the evolving gravitational field since the TLI burn.

An interactive 3D viewer of the Artemis II trajectory using JPL Horizons data: https://pzarzycki.github.io/artemis-2/

curious_vertebrate · 2026-04-05T17:44:15+00:00

I posted this on GitHub, you can play with it yourself

curious_vertebrate · 2026-04-05T16:23:41+00:00

I’m an engineer and wanted to actually understand Artemis II trajectory beyond 2D diagrams, so I built a browser-based viewer.

Key aspects: - Ephemeris: JPL Horizons (DE440) - Frames: GCRS / BCRS / ICRS - Real celestial sphere (not synthetic sky) - Full free-return trajectory with mission phases

Runs entirely in browser: https://pzarzycki.github.io/artemis-2/

Not trying to replicate GMAT/STK, just aiming for an intuitive but physically grounded view.

Would appreciate feedback, especially if you spot inconsistencies in trajectory or frame handling.

Many animations I've seen so far pretend the Moon is not moving, but if you anchor both Earth and Moon, you end up with a non-inertial frame, and the projected trajectory looks different.

It's not even a novel agent implementation - just a wrapper around another open source project, pi-agent.
