Aurora Australis: A Tribute to Sergey, Sergei & Chris | International Space Station
Expedition 74 flight engineer and NASA astronaut Jessica Meir: "Our crewmate Chris Williams, stated a few weeks ago that he was hoping for another round of aurora viewing from the International Space Station before his departure, and the solar system delivered! Wishing the 74S crew a journey home that is as spectacular as the ethereal glow of the Aurora Australis. It has been an absolute honor flying with you Sergey, Sergei, and Chris."
Roscosmos cosmonaut Sergey-Kud-Sverchkov of Russia handed over command of the orbital outpost to Jessica Meir this Saturday morning, July 25, 2026. Then he, Sergei Mikaev, and Chris Williams will end their eight-month space research mission at 3:03 a.m. on Sunday when they undock from the Rassvet module aboard the Soyuz MS-28. Expedition 75 officially begins and Expedition 74 ends when the Soyuz departs the orbital outpost. They will parachute back to Earth inside the Soyuz and land in Kazakhstan at 6:25 a.m. EST (3:25 p.m. local time).
Also known as the northern lights (aurora borealis) or southern lights (aurora australis), auroras are colorful, dynamic, and often visually delicate displays of an intricate dance of particles and magnetism between the Sun and Earth called space weather. When energetic particles from space collide with atoms and molecules in the atmosphere, they can cause the colorful glow that we call auroras.
