Today – October 28th – we are exactly 100 days from the opening of the Artemis II launch window.
In 100 days, these four astronauts could be in Earth's orbit and heading out to the Moon.

What will the Moon look like from Earth when the Artemis II astronauts are flying by the Moon? I simulated it in a few places around Montréal...
The earliest possible launch date is February 5th, 2026. The astronauts would arrive at the Moon around February 10th, which I've simulated here.

Sputnik launched on October 4, 1957. The first steps on the Moon were July 20, 1969.
Less than a 12 year gap.
That's the amount of time between the iPhone 5s and the iPhone 17.

The last mission to the Moon was December, 1972. Nobody under the age of 53 has ever looked up at the Moon while humans traveled around it.
That's about 75% of people alive today. 6 billion people.
In just a few months, the Artemis II mission is going to change that.

There's only ~30 satellites needed to make GPS work around the world. I wanted to show this to students, and I'm super pumped how this turned out!
Working with @gaiasky.bsky.social, we grab the orbital data of each satellite and show them circling around Earth
They look like electrons in an atom

This morning I attended the Artemis II crew press conference streamed from the CSA headquarters.
I learned a bunch of new, cool things about the mission. I whittled my long list down and wrote about 5 of them.

Went to a press conference at the Canadian Space Agency this morning about the Artemis II mission
The 4 astronauts were down in Houston answering questions
Took a ton of notes and learned some super cool things about the mission. I’ll write a post summarizing the things I thought were super neat.
