Live tomorrow: ESA astronaut @Soph_astro's first spacewalk, alongside NASA astronaut Anil Menon, to replace a crucial piece of equipment on the ISS. Watch from 12:00 BST / 13:00 CEST on ESA WebTV and YouTube. 🔗esa.int/Science_Explor…

In preparation for its first Trojan asteroid encounter, NASA's Lucy spacecraft took images of its future targets - Eurybates, Polymele, Leucus, and Orus. The spacecraft will fly past these four asteroids between August 2027 and November 2028. 🔗 go.nasa.gov/4icbsar

Join us in wishing a happy 90th birthday to Margaret Hamilton! As the leader of the MIT software development team that created the Apollo spacecraft's guidance software, her work was invaluable to the success of the Apollo 11 Moon landing. 📸 Hamilton and Apollo code, 1969. Courtesy of MIT Museum

Today we are celebrating National Nonprofit Day! At Astronauts For America, we're committed to protecting our constitutional democracy and empowering future generations to make their voices heard. Learn more and support our mission at AstronautsForAmerica.org.

Did you know, @TheMarsSociety was founded in 1998🌐 For over 28 years, Dr Zubrin and volunteers have had one collective mission: Occupy mars🚀 Many have stepped in to help, and now it's our time as a community to make a real impact🔶

Two astronauts from @NASA and @esa are go for a spacewalk on Tuesday. Meanwhile, Expedition 75 worked on cardiac research, artificial intelligence, and Earth observations on Monday. More... go.nasa.gov/3SdL2uw

Investing in space exploration isn’t just about space. I've made this argument a lot—as an astronaut and as a senator. The pushback is always the same: why spend money up there when we have problems down here? Here's the thing: we're solving problems down here by exploring what’s up there. In 2001, I flew on Space Shuttle Endeavour to the Space Station. We carried out studies on bone density loss in microgravity. That research contributed to the development of Prolia and Xgeva, drugs now used to treat bone loss in cancer patients. People are alive today in part because we went to space. Two NASA engineers at Glenn Research Center developed a tiny implantable transmitter to monitor astronaut vital signs when they exercised in space. A company licensed and used it to build a monitor that warns heart failure patients of a potential crisis. NASA needs medical diagnostics for astronauts millions of miles from a hospital. That challenge produced a portable device that tests a single drop of blood for diabetes, kidney function, and cardiovascular disease in minutes. It's now being used by Massachusetts General Hospital and Harvard Medical School. It exists because we‘re working to put humans on Mars. NASA helped build the Search and Rescue Satellite-Aided Tracking system. Satellites carrying this technology link emergency beacons to rescue teams worldwide. It has helped more than 63,000 search and rescue operations. World Central Kitchen uses data from NASA's Earth Observing System satellites to build maps guiding staff distributing food and water in disaster areas. The satellites were built for science. Now, they're saving lives on the ground. I flew four shuttle missions. I know what it costs to get humans into space. The innovation that comes from pushing humans to the edge of what's possible finds its way back down here. Into hospitals, kitchens, and the hands of first responders. And also into yours. That's why I'll keep fighting for NASA's budget. Not just because I believe in science and exploration. Because I know what science and exploration makes possible here on Earth.

For #ERC2026, we’re heading to @AGH University of Science and Technology — our Co-organizer and the home of this year’s Challenge. A place where engineering, science and curiosity meet! And, for three days, where Earth gets a little closer to Mars. 🌍🔴

Day 185 orbit 2868 — I’m ready to go! 🌍🧑‍🚀 Tune in tomorrow, 18 August, from 13:00 CEST to watch me work in the vacuum of space, live from orbit! 🎥 @esa / @NASA #εpsilon • @esaspaceflight • @Space_Station • @NASAJohnson

Our next space telescope is launching in just under two weeks! In the first episode of our NASA's Curious Universe podcast series on @NASARoman, we get to know the telescope's namesake and what cosmic mysteries it will help us to unravel. go.nasa.gov/4hz20hc

Tomorrow, two astronauts will be going on a spacewalk! Beginning at about 8:35am ET (1235 UTC), astronauts @astro_anil and @Soph_astro will step outside the @Space_Station to replace a communications antenna. Tune in at 7am ET (1100 UTC): youtu.be/yW-VAhqVJok

"Snoopy, Baseball, and NASA" is the title of my interview in the latest edition Air & Space Quarterly, the magazine of the Smithsonian National Air and Space Museum. I love the tagline: "A Long Island kid who loved Charlie Brown and the New York Mets would one day repair the Hubble Space Telescope."
