Starliner’s next crewed flight will have an exceptional commander in @Astro_Woody. He is an accomplished and experienced astronaut, knows the Starliner spacecraft, and brings the technical expertise and operational judgment we want in the commander’s seat. He has my complete confidence.

Starliner will get extra help from NASA, and if it can sort out its problems it'll fly with a crew in 2028, and also be adapted to fly on the Vulcan.
The uncrewed Starliner-1 mission is planned for the December 2026/January 2027 timeframe. Together with @NASA, we're making Starliner hardware enhancements and adding resources for human spaceflight certification. These changes support the spacecraft as a long-term provider of crewed missions to low Earth orbit.

In Houston at the Off World conference today, NASA’s Jared Isaacman said there would be an “Artemis acceleration” event to discuss plans to bring forward the Artemis IV lunar landing in “early October.”

I have spent 23 years documenting the global LED transition of city lighting from space. Across my 4 missions to the ISS, I have photographed every major city on Earth, building a data set of the gradual replacement of sodium vapor lighting with LEDs. The warmer, yellow-orange of gas discharge lamps has been phased out worldwide to multi-colored LEDs, citing energy savings and environmental reasons. Widespread adoption has markedly changed the way our cities look from orbit, and as many have pointed out, how they feel to those on the ground! Here is a collection of the most striking before-and-after photos I have observed:
Miami, Florida as seen from the ISS in 2025. This city has changed tremendously since my previous mission, replacing its yellow-orange sodium vapor lights with multi-colored LEDs. The city grid really pops! This LED takeover of city lighting is world wide.

Success! Roman’s planned mid-course correction burn went as expected, ensuring that we are on track for our orbit around the second Lagrange point, a million miles from Earth. go.nasa.gov/4A3zDi2

Falcon Heavy landing from the NASA Causeway. All six sonic booms can clearly be heard, one for each landing leg. – at Titusville, FL
Readers added context they thought people might want to know
Falcon Heavy side boosters each produce a triple sonic boom from their geometry (base, grid fins/lower body with folded legs, top) during supersonic flyback, not one per landing leg. Legs remain folded and deploy only after subsonic near touchdown. acoustics.org/2apaa6-boom-bu… aip.org/scilights/grid…

This weekend, @NASARoman launches to join @NASAHubble and @NASAWebb in space, teaming up to expand our view of the universe. Each telescope brings a unique set of skills and interests. Curious where you’d fit in the exploration squad? Find out which telescope you are!

Introducing Artemis III. Four astronauts. Three launches. Two dockings. One splashdown. In 2027, the Artemis III mission will practice docking the Orion spacecraft with two lunar landers in low Earth orbit — the capability we need to return humanity to the Moon’s surface.
