@KevinEspiritu The rootstock stays, it's only the aboveground part that's cut down after harvest. A cycle takes 6-8 months. So you can get about two harvests a year from one mature rootstock.

Easter Moon from @Space_Station (almost egg-like tonight). Turns out my four @NASAArtemis friends are somewhere in that frame, too. As are the rest of you in the second photo, as the blue glow of Earth's atmosphere draws the Moon in. Seconds after this shot, it had disappeared completely, setting behind its Mother Earth.

For the Belgians: the true size of the Strait of Hormuz! (Thank you @truesizeof )

I've plotted the most expensive McDonald's burger and the least expensive MacBook over time. This analysis projects that the most expensive burger will be more expensive than the cheapest laptop as soon as 2081

👀On m’a souvent demandé si la muraille de Chine était visible depuis l’espace… mais non, elle est trop fine (et pas assez de contraste).

📸 Il n’y a que peu de bâtiments individuels qu’on distingue à l’oeil nu, mais parfois, en pointant son téléobjectif, on trouve quelques surprises : sur cette photo, le toit rouge et un logo bien connu se détachent nettement à Abou Dabi 🇦🇪, et on peut même suivre autour du parc à thème Ferrari World (parce que c’est bien de cela qu’il s’agit) le tracé du circuit de Yas Marina, où le grand prix vient d’avoir lieu ce weekend.

🏁 Bravo aux pilotes et aux équipes, comme beaucoup de gens je n’ai découvert leur quête de la performance qu’assez récemment et à travers la série @NetflixFR qui se plonge dans leurs coulisses.

⚠️ Et puisqu’eux sont des professionnels entraînés, sur des circuits sécurisés, pour tous les autres : conduisez prudemment 😉

@bscholl We kind of have this in Europe. It's called "slots".... Best queue and gate management you can get. It's also able to absorb delays efficiently.

@Liv_Boeree The signs of enshittification?

[Barack Obama @BarackObama]

Jane Goodall had a remarkable ability to inspire us to connect with the natural wonders of our world, and her groundbreaking work on primates and the importance of conservation opened doors for generations of women in science. Michelle and I are thinking of all those who loved and admired her.

[Chris Hadfield @Cmdr_Hadfield]

With enormous sadness we said goodbye to our mother today, Eleanor Hadfield. She gently passed away after 89 full years, with grace and in no pain, surrounded by loving family. Eternal thanks to all the kind people that helped her when she needed it most. We will always love and miss you, Mom - your calm and music will be with us forever.

[Bill Maher @billmaher]

Let’s make a deal at a grand bargain between the two sides that hate each other so much. The Left will quash all their loony woke shit, and the Right will stop the slide into autocracy.

Nana's 100th birthday. Crazy to be born on 9/20/25 and then have it get to 9/20/25 AGAIN.

[Tim Urban @waitbutwhy]

"How would I feel if the other team were doing this?" is always a good question to ask yourself. If you'd feel very differently, it means you've slipped into a tribal mindset and need to get back over to the circle on the right.

[Ken Kirtland IV @KenKirtland17]

This is one of the more amazing things I’ve witnessed.

For non space people this would be a news segment like:

“A car was seen driving on a road today!”*cuts to footage of a boat on the water*

[Gregor @GregorPfyffer]

@SciGuySpace @AndySaunders_1 rocks!

[Gregor @GregorPfyffer]

@MarkFriedenbach Does anyone know cheap red markers?

[Gregor @GregorPfyffer]

@PettitFrontier @SciGuySpace I'd be wary to state that its launch is a certainty. The current state of NASA (politics) does not guarantee it beyond any doubt....
