Like many space folks I often agree with both meme quotes simultaneously. I asked an AI for some help: rap/song lyric, Shakespeare, Haiku. (sigh) Same result. Thanks @Grok. #AdAstra Y'all

Expedition 75 vibes. It was an honor and privilege to serve as Commander of the @Space_Station! After welcoming Crew-13 this week to mark the second part of Expedition 75, today I handed over the key to the @Space_Station to my friend and colleague Pyotr Dubrov. This ship is in the best of hands!

As is often the case @Grok found the right balance point.

Thomas Zurbuchen joins Blue Origin ethz.ch/en/news-and-events/e… "What will you be doing in your new position? In my role as Senior Vice President, I will lead Blue Origin's Advanced Concepts team in the US, which develops next-generation concepts and systems to advance a sustainable future of living and working in space. That means we’ll have a major say in what this space technology company builds next. This challenge really appealed to me. In my opinion, Blue Origin sits at the forefront of space technology development. @Dr_ThomasZ @blueorigin

“Rocket Revolution” is the theme for #WorldSpaceWeek 2026 🚀 Access to space is now expanding as costs fall and technology becomes more widely available. New space actors must ensure that space science & technology continue to contribute to the #SDGs. buff.ly/DrEHbll

What happens when amateur astronomers help uncover thousands of previously unknown brown dwarfs? 🔭 In this episode of the SETI Live podcast, Dr. Adam Schneider explains how volunteers with NASA's Backyard Worlds: Planet 9 project contributed to the discovery of roughly 3,000 brown dwarfs — and why around 60 citizen scientists earned co-author credit on the research. 🎧 Listen to the conversation with host Dr. Lauren Sgro: sites.libsyn.com/462636/not-… #CitizenScience #Astronomy #BrownDwarfs

The second Qingzhou cargo spacecraft, which will bring supplies to Tiangong no earlier than January 2027 via a Kinetica-2, has recently passed into the 'development' phase of production to complete its assembly Details -> china-in-space.com/p/qingzho…

Today in 1957, the Soviets open a new front in the Cold War with the launch of history's first human-made satellite, Sputnik I. For 21 days the 184-pound, beachball ball-sized orbiter transmits a constant radio signal back to Earth: "Beep... Beep... Beep!"

.@POTUS: I recently announced we will be establishing a brand new U.S. National SPACE ACADEMY. Every other state wants it, but I have no doubt that — as the birthplace of aviation and home of the Wright Brothers — if we win, Ohio will be under STRONG consideration.

A quick hello from the @Space_Station.

Congratulations to the @NASA workforce and our partner @SpaceX on another successful crewed launch to the International Space Station. Crew-13 is now aboard the station, Crew-12 will be home soon, and 2026 is far from over. Still ahead: more science missions, more flyovers, the MAX POWER exposition, cargo resupply, a possible Starliner-1 demonstration mission to the ISS, Artemis III rollout and tanking tests, and the first Moon Base launch before the year ends. We will never stop going. 🇺🇸

With 280+ reports and 320+ events across 244 topics in the past year, there’s a lot happening at the National Academies. Our new Substack will help you discover work you might otherwise miss — and we want to hear what you’d like to see there. Follow us: ow.ly/C5aq50ZU7rK
