Hi all, I’m taking a few weeks off (or may be intermittent, if things go well) from social media to address a left-eye issue. Have a lovely few weeks in the meantime. Cheers, Ashley
Memorial Day 2026
We’re keeping in our thoughts and prayers all of those who served in our armed forces, sacrificing to preserve our freedom. We bless you and thank you and will take a moment of silence to remember you.
🌍 Ever wondered where Earth ends and space begins?
Let's take a quick journey up through the atmosphere:
✈️ Troposphere (0–11 km) — where we live, breathe, and where planes fly. 99% of all weather happens here. ☁️
🚀 Stratosphere (11–50 km) — home to the ozone layer that protects us from UV rays. Commercial jets cruise at its bottom edge.
🔥 Mesosphere (50–90 km) — the "meteor burner." This is where most shooting stars burn up. Also the coldest layer: down to -90°C! ❄️
🛸 Kármán line (100 km) — the official (unofficial) boundary of space. Above this line, aerodynamic lift becomes ineffective. Wings are useless — you need rockets.
Two cool facts:
🧠 1. The Kármán line is named after physicist Theodore von Kármán. But he actually proposed ~84 km. The 100 km mark was chosen as a nice, round number!
🛰️ 2. Even at 400 km (where the ISS orbits), the atmosphere isn't completely gone. The ISS loses about 2 km of altitude every month and needs regular boosts!
So next time you look up at the sky — space is just 100 km above your head. You could drive there in about an hour… if there was a vertical road. 🚗⬆️

Voyager 1 is about to make history 🚀✨
In November 2026, NASA’s legendary probe is expected to become the first spacecraft ever to be one light-day away from Earth — so far that a signal from us would take a full 24 hours to reach it.
Launched in 1977, Voyager 1 is still traveling through interstellar space nearly 50 years later. By around November 15, 2026, it should be about 16.1 billion miles (25.9 billion km) from Earth. 🌌
Humanity really built something in the 1970s… and it’s still going. 🥲

Welcome home Reid, Victor, Christina, and Jeremy! 🫶
The Artemis II astronauts have splashed down at 8:07pm ET (0007 UTC April 11), bringing their historic 10-day mission around the Moon to an end.
