Gwynne Shotwell (President of SpaceX) on her biggest realizations while working for @elonmusk : "There is two really important realizations for that. First of all, when Elon says something, you have to pause and not immediately say out, blurt out, well, that's impossible, or there's no way we're going to do that, I don't know how to do that. So you zip it, and you think about it, and you find ways to get that done. And the other thing I realized, and it made my job satisfaction substantially harder. So I always felt like my job was to take these ideas and kind of turn them into company goals, make them achievable and kind of roll the company over from this steep slope, get it comfortable. And I noticed every time I felt like we were there, we were rolling over, people were getting comfortable, Elon would throw something out there, and all of a sudden we're not comfortable and we're climbing that steep slope again. But then once I realized that that's his job, and my job is to get the comfortable, close to comfortable, so he can push again and put us back on that slope. Then I started liking my job a lot more. Instead of always being frustrated.

Rest easy, Captain. We have the helm. ✨ This is Webb’s look at Westerlund 1, a super star cluster. Because our galaxy is past its peak of star formation, and because stars live relatively short lives, only a few of these clusters exist to give us clues to that past era.

SIR PATRICK STEWART (1940-2026) Before everything else, Patrick was defined by being born and bred in Yorkshire, the proud county in the north of England which he loved to the end. You could hear it in his accented voice and in the stern honesty with which he told you what he thought and felt. Yorkshiremen have no truck with half-truths or avoidance of big issues. He wore his heart on his sleeve, which made him a man to rely on, to admire and in my case, love. We first met as ambitious young actors with the Royal Shakespeare Company half a century ago but we weren’t in the same productions. My first strong memory was a few years later, meeting him in the street in central London when he told me about an offer to take over a leading part in 'Star Trek'. “But Patrick think of your stage career in the UK. Do you really want to risk—getting lost in Hollywood for years and years?”. Well, he took the risk and thank goodness for us all that he did for not just his devoted Trekkies but film and theatre audiences, who marvelled at his using international celebrity to star in a string of cinema successes ('X-Men' of course) and in great classical plays by Shakespeare, Ibsen, Arthur Miller, Peter Shaffer, Pinter and Beckett at Stratford-upon-Avon, in London’s West End and on Broadway. America was his adopted home, where he met his adored Sunny who has cared for him through sickness and health, through thick and thin. But he never forsook his origins: and the proudest achievement of the most respected and beloved actor of his generation on either side of the Atlantic, was his appointment as Chancellor of Huddersfield University in Yorkshire. His farewell performance in 'Avengers: Doomsday' is yet to be seen. Ian McKellen 29 October 2026 Photo: University of Huddersfield

Hmm, something was nagging in the back of my mind about SpX, I think Eric nailed it here. It is going to be interesting in 2027/28.
I’ve spent a lot of time thinking about, and talking to people about a post-Falcon world. Why sunset the world’s best rocket? Can Starship replace it? What about Artemis? Why are SpaceXers flocking to Memphis? Grab a coffee, this is a long one. arstechnica.com/space/2026/1…

Are you watching Germany?
Need a crumb of hope about Europe on a Saturday? Belgium has gone from rapidly closing and destroying its entire nuclear fleet (half of its power before 2023) to quickly relicensing and returning a few of them to the grid. PM @Bart_DeWever is trying to save as many as he can.

Onder Donald Trump verandert de VS steeds meer in een corrupte oligarchie - met Rusland als voorbeeld, zegt HCSS defensie expert @PPMBolder in @ADnl. Trump heeft een hekel aan Zelensky en bewondert Poetin; een van de grootste oorlogsmisdadigers ooit. ad.nl/buitenland/oekraine-vr…

The current US in a nutshell. It would have been hilarious if it wasn't so sad
BREAKING: The Florida televangelist who claimed that if Republicans lose control of Congress in the midterms Satan will conquer the US and force everyone at gunpoint to turn gay or trans or both just got arrested after his secret meth lab in his church's basement caught fire.

I have been a posting slug! How about that launch triple header last week: Starship, Crew 13, and Heavy!!! Terrestrial low band spectrum acquisition and FCC approval for Starlink Mobile constellation! And I am always relieved, grateful and proud when we complete a crew mission— welcome home to Mother Earth Crew 12!
Splashdown of Dragon confirmed!

Leaving Earth is hard. Leaving your family behind us harder. Before driving to the launch pad to fly to the @Space_Station; @csa_asc Astronaut, @Astro_Kutryk reached through the window for a final touch and goodbye to his pregnant wife. Behind every grand leap into the cosmos, is an extraordinary sacrifice made right here at home. #SpaceX #NASA #Crew13 #CSA #JoshuaKutryk 📷 Credit: Trevor Hicks for @TheLaunchPadX

Inspector Smile is ready for science! 🫡 This is Smile’s first ultraviolet view showing an auroral substorm. With the ultraviolet camera now operational, Smile becomes the first spacecraft since 2008 to capture the full ring of northern lights around the north pole in ultraviolet light. 1/4
