Day 069, orbit 1071 — The gyroscope, key to maintaining a spacecraft attitude in space 🌀
A spacecraft’s attitude is the direction it is pointing in space – crucial information for correctly aligning its antennas, solar panels, and cameras. To stay stable and maintain its attitude, the Station relies on four Control Moment Gyroscopes (CMGs), large spinning wheels that use angular momentum to keep it properly oriented.

Virginie Bonnaillie-Noël (ENS) et @gabrielpeyre : on a "très clairement une rupture", des post-docs rapportant que leur thèse peut désormais être faite par l'IA en quelques minutes plutôt qu'en 3 ans ; "les performances sont assez incroyables", et "ça change incroyablement vite".

Έμαθα ότι ο Φρανσουά Ολάντ είπε στη γαλλική τηλεόραση ότι «έσωσε» την Ελλάδα παρά τις «προσπάθειές» μου (προφανώς να... μη σώσω την Ελλάδα). Ένιωσα σαν να με κατασπαράζει ένα νεκρό πρόβατο σε προχωρημένο στάδιο σήψης.

Ces vues du lancement d'Ariane 6 depuis toutes ces caméras autour du pas de tir permettent de voir plein de petits détails: séparation des bras cryo, manœuvre de roulis, séquencement des déluges, etc.
Bon dimanche à tous et toutes, et joyeux 14 juillet. 🇨🇵

How to Get to Orbit Cheaper than SpaceX's Starship
Ian Brooke has developed a new kind of jet engine that can act as the first stage of a rocket.
I get brunch with him every Sunday and have grilled him for hours on how it works.
Adaptive Cycle Jet Engines, the primer 🧵
I've kept a pretty low (online) profile of what I'm building, but word's getting out.
My company Astro Mechanica has invented a new kind of jet engine. Unlike any existing engine, it's efficient at every speed. Because it's efficient at every speed, we can use it in a new way: as the first stage of an orbital launch vehicle.
The resulting platform will get payloads to orbit dramatically cheaper than all-rocket systems - among many possible applications.
The key insight is to use electric motors to drive a compressor. That way we can make it spin at any speed, allowing it to "adapt" to it's airspeed and combustion cycle.
One of the coolest parts: the video below is of a demonstrator my team and I built last year. We already have a new engine with 10x the thrust that will be complete next month.

I was left on the brink of tears by this interview with South African Jewish former ANC MP @andrewfeinstein.
He tells me why Israel's oppression of the Palestinians is so much worse than Apartheid - and so much more

Each second, 1.5 million tons of solar material, traveling at 100 miles per second, shoot off the sun. Earth's magnetic field deflects most of it, but not all. The solar wind, a stream of charged particles, flows at 447 km/s (1 million mph), and while the magnetic field protects us, some particles still cause auroras and geomagnetic storms.
