Auroras meeting the Milky Way galaxy.

Exp 73 installed advanced physics research gear to inform deep space missions and inspected lab hardware to keep the station in tip-top shape on Tuesday.

From low Earth orbit to the Moon, Mars, and beyond! 🌙🚀 The space station is humanity's launchpad to deep space where we refine our knowledge, advance technologies, and learn to thrive as we prepare to venture further into the cosmos. https://t.co/0ZrcIpE2KR

Ready, steady, spin!💫 From space telescopes aimed at distant cosmic objects to the @Space_Station orienting its solar panels towards the Sun, @AstroHague explains how gyroscopes help spacecraft remain pointed in the right direction.

Foam physics, ultra-hot materials, and space debris tech—Exp 73 kicked off the week configuring cutting-edge science gear. A blood circulation study and @SpaceX Dragon checks rounded out the schedule aboard the station.

Category 4 Hurricane Humberto and its lightning pictured at night above the Atlantic Ocean.

Humberto was a Category 1 hurricane with 90-mile-an-hour winds in the Atlantic Ocean when Jonny Kim photographed the storm on Sept. 26.

Exp 73 wrapped up the week studying how space affects the sensory system, digestion, and even DNA data storage. The @SpaceX Dragon also reboosted the station’s altitude to prep for upcoming crew swaps.

Eye structure, digestion, and heart health were the top research subjects for the Expedition 73 crew aboard the space station on Thursday.

NASA astronaut Chris Williams will discuss his first mission to the orbital outpost during a live news conference on Oct. 1 from @NASA_Johnson. He is targeted to launch aboard a Soyuz spacecraft on Nov. 27 for an eight-month space research mission. More... https://t.co/oI7wUMN6H2

.@NASA and @SierraSpaceCo have updated their resupply contract to include a free flight demo of the Dream Chaser spaceplane targeted in late 2026. This move supports spacecraft development and aligns with a shift toward commercial space stations.

Typhoon Ragasa was raging in the Philippine Sea south of Taiwan and Typhoon Neoguri was spinning in the Pacific Ocean southeast of Japan on Sept. 21 when these photos were taken from the station.

We've got you loud and clear and standing by to say hi! 📞 Next year the crew aboard the station will have the opportunity to take part in a ship-to-ship call with the four humans inside the Orion spacecraft "named Integrity" as they travel to the Moon as part of @NASAArtemis II.

Buzz, buzz! Our Astrobee robots have been buzzing around the @Space_Station for six years! From creating 3D maps to detecting and alerting astronauts about a simulated anomaly, the free-flying robots have marked multiple first-in-space milestones. Discover what’s

Fitness research and vision studies topped Wednesday's schedule for the Exp 73 crewmates who also worked hatch inspections, cable installations, and robotic communications.

The Canadarm2 robotic arm from @CSA_ASC helps astronauts during spacewalks, moves gear, and grabs cargo ships—while Dextre, its nimble robotic hand, handles delicate repairs. Together, they keep the International Space Station running smoothly.

Violent Typhoon Ragasa and Neoguri from the International @Space_Station. Sept 21, 2025 0437 GMT. Nikon Z9 | 24/50-500mm. From orbit, the view is breathtaking, but on the ground, this storm brings real danger and hardship. Thoughts are with everyone in its path, and with the
