Amazing to watch launch umbilical cords retract in the nick of time.
Rockets need to stay connected to their launch pad right to the last second, for fuel/gases, data and power. But the hot blast from the engines would cook the plumbing parts.
So they unplug, run away and hide in a safe room, slamming the door behind them. Ready to be used again.

Thanks! Glad you enjoyed it. Deep into writing the 4th in the Apollo Murders series now.
@Cmdr_Hadfield You completely had me in Final Orbit. Great writing.
The F-86 Sabre and F-18 Hornet were only 34 years apart.
Both were a great pleasure and privilege to fly. So responsive and cutting edge in technology. Freedom in 3 dimensions.
But given the choice, I'd fly the Spitfire. Such a beautiful pilot's machine.

What the Prime Minister is reading this summer.
Biography, thriller, activism. Excellent company to be keeping.
Reminder - please read with a child daily, thanks.

Nice to see The Apollo Murders as "a book like Project Hail Mary that will blow your mind."
And recommended by @andyweirauthor too! @Vocal_Creators

Where were you when the eclipse hit today? 🌖✨
While millions watched from the ground across Europe, we had a view from space. 🛰️
Did you catch the total or partial eclipse where you are? Let us know in the comments - and check back tomorrow for more imagery and information! 💬

While millions watch today’s solar eclipse from Earth, we wanted to share a unique view of the same phenomenon from space. 🌑🌍
From orbit, you don’t see the eclipse - you see its shadow sweeping across our planet.
Captured by Sen’s 4K cameras on 8 April 2024.

Total solar eclipse today! The Moon blocking the Sun.
Late afternoon for folks in Greenland & Iceland, sunset hour for Spain (the yellow band on the map).
Partial eclipse visible in N America, Europe and Africa.

Astronaut reminder - don't look right at the Sun! It'll fry your eyes.

This old star is running out of fuel. The Lion Nebula.
All that's left is a hot white dwarf, cooking the outer dust from inside, blasting it with bubbling ionised gas.
At enormous, beautiful scale.

Seeing the world through my children’s eyes allows us to share the wonders of the universe, from a flower to the stars.
And seeing is so important - yet 1 in 4 children have a vision problem by school age. Luckily, regular eye exams and early detection help support healthy vision, so children can explore and learn with confidence.
Make sure they don't miss a minute – book an eye exam at @Specsavers.

Good morning, my country (with a nod to legend inventor Alexander Graham Bell) 🇨🇦
Our beautiful world at night, from the International Space Station as it pivots. Living on board, you get intimately familiar with the planet’s shapes and textures, and where we choose to live.
Great video from @astro_Pettit

Timelapse of the ISS Optimal Propellent Maneuver (OPM)! We use this to reorient station's attitude in preparation for docking events. This one occurred over some magnificent Mediterranean city lights!

On Wednesday one of these will crash into the Moon.
It's a @SpaceX Falcon 9 upper stage rocket & tank, used to propel lunar landers last year. It will hit near Einstein Crater at 5400 mph/8700 kph, blasting a crater 90ft/27m across, 16ft/5m deep.
Total, the Moon has been hit by 800+ human-made objects, but that's dwarfed by the natural impacts: tens of thousands of similar new meteor craters every year.
The Moon has no life or ecosystem to disrupt, but as we start landing more, we need to better track what we're doing: @openlunar has the world-leading Lunar Ledger ( doing just that.

We need heat shields to protect us, since we use the air to slow us down as we return to Earth.
From orbital speed, it gets to 1650°C / 3000°F. From the Moon: 2750°C / 5000°F.
For yesterday's Starship suborbital test flight, peak was 1450°C / 2600°F. Great to see the @SpaceX progress over the last 3 flights. Making them truly reusable is complex and necessary for permanent, cheap space access.
