On Thanksgiving Day, NASA astronaut Chris Williams begins his first mission in space. Williams and his crewmates launched aboard a Soyuz spacecraft, arriving safely at the International Space Station at 7:34 a.m. EST (1234 UTC).  https://lnkd.in/earRMv9w

Thanks to our James Webb Space Telescope, this cosmic spiral is coming out of its shell! You're looking at Apep, a star system with distinct shells of dust spiraling around the central trio of stars. Previous observations could only detect one shell, but scientists hypothesized the existence of others. Now, Webb has revealed four! Learn more about this image and Apep: https://lnkd.in/eNXw2tW4

"Thanksgiving, for me, is a time to pause, slow down, and reflect on our lives, the people we cherish in our lives, and all the support we've had on this journey." From the International Space Station, astronauts Jonny Kim, Zena Cardman, Mike Fincke, and JAXA's Kimiya Yui share their thoughts, plans, and gratitude for the Thanksgiving holiday.

NASA astronaut Chris Williams is launching on his first-ever flight to the International Space Station aboard a Roscosmos Soyuz MS-28 spacecraft. The crew is scheduled to lift off from the Baikonur Cosmodrome in Kazakhstan at 4:27 a.m. EST (0927 UTC) on Thursday, Nov. 27. Live launch coverage is available on YouTube and NASA+: https://lnkd.in/eV2-3SFZ

On Oct. 28, 2025, our X-59 aircraft, designed to fly at supersonic speeds and reduce the sound of loud sonic booms to quieter sonic thumps, took off for the first time. For this first flight, a NASA test pilot flew the X-59 slower than the speed of sound and at an altitude that allowed the team to conduct in-flight system and performance checks. Read more about the flight: https://lnkd.in/exQ2_psX What’s next for NASA Aeronautics and the X-59? We’re prepping for a series of test flights where the plane will operate at higher altitudes and supersonic speeds. This phase will ensure the X-59 meets performance and safety expectations.

Calling all digital creators! Would you like to see our Artemis II crew off on their trip around the Moon? We’re looking for social storytellers to attend our NASA Social at NASA Kennedy for the first crewed launch in the Artemis program. Applications for our NASA Social are open from now through Monday, Nov. 24. Learn how to apply: go.nasa.gov/47R5ZR3

We've just released our newest images of the interstellar comet 3I/ATLAS, the third object we've ever seen passing through our solar system from elsewhere in the galaxy. Its trajectory will take it no closer than 170 million miles from Earth—almost twice the distance between Earth and the Sun. Every observation our spacecraft and telescopes have made is consistent with 3I/ATLAS being a comet. Interstellar objects give us a unique opportunity to learn more about what solar systems beyond ours are made of, so astronomers have been keeping a close eye on comet 3I/ATLAS on its arc around our Sun. Over the last several weeks, we've been studying the comet from our Lucy mission en route to the asteroid belt, our Sun-watching PUNCH satellites in low Earth orbit, and even our Perseverance rover on Mars!

We're hosting a live event on Wednesday, Nov. 19 to share the latest images of the interstellar comet 3I/ATLAS, collected by several NASA missions. First observed earlier this year, the 3I/ATLAS comet is only the third object ever identified as entering our solar system from elsewhere in the galaxy. While it poses no threat to Earth and will get no closer than 170 million miles to Earth, the comet flew within 19 million miles of Mars in early October. This image of 3I/ATLAS was taken by our orbiting Hubble Space Telescope in July. Tune in for Wednesday's livestream: https://lnkd.in/eJFj5RJw Learn more about the comet: https://lnkd.in/eXP5ZCwn

After a successful launch, Sentinel-6B has reached low Earth orbit to continue a legacy of recording Earth’s sea levels. All systems are functioning normally. This satellite is an international collaboration taking over for Sentinel-6 Michael Freilich. Sentinel-6B and its predecessor contribute to a series of missions spanning over 30 years that study Earth's changing seas. Learn more about the mission and what it will teach us: https://lnkd.in/efRzddvA

This new satellite will measure sea levels for almost all of Earth’s ocean 🌊 Data from Sentinel-6B will help improve weather forecasts, protect coastal communities, keep ships safe at sea, ensure astronauts splash down safely, and more. Sentinel-6B is the latest in a line of satellites that has been measuring sea levels for over 30 years. It was jointly developed by NASA, ESA, EUMETSAT, and NOAA, with support from the European Commission and CNES.
