NASA Astronaut Jonny Kim Returns from ISS Mission

NASA astronaut Jonny Kim returned to Earth on Tuesday after completing an eight-month science mission aboard the International Space Station, landing safely in Kazakhstan alongside two Russian cosmonauts. The crew, which included Roscosmos' Sergey Ryzhikov and Alexey Zubritsky, touched down southeast of Dzhezkazgan at 10:03 a.m. local time following a parachute-assisted descent in their Soyuz MS-27 spacecraft. They had undocked from the station the previous evening at 8:41 p.m. EST on December 8, capping a 245-day expedition that advanced research for both earthly applications and future space travel.

The trio launched from the Baikonur Cosmodrome in Kazakhstan on April 8, docking with the station about three hours later. During their time in orbit, roughly 250 miles above Earth, they circled the planet 3,920 times, covering nearly 104 million miles. This marked the first spaceflight for Kim, a Los Angeles native and son of Korean-American immigrants, as well as for Zubritsky. Ryzhikov, by contrast, completed his third mission, bringing his cumulative time in space to 603 days.

Aboard the orbiting laboratory, Kim contributed to several key experiments. He examined the behavior...
