NASA astronaut Jonny Kim returned to Earth on Tuesday alongside Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, wrapping up an eight-month science mission aboard the International Space Station to benefit life on Earth and future space exploration.

They made a safe, parachute-assisted landing at 12:03 a.m. EST (10:03 a.m. local time), southeast of Dzhezkazgan, Kazakhstan, after departing the space station at 8:41 p.m. on Dec. 8, aboard the Soyuz MS-27 spacecraft.

Over the course of 245 days in space, the crew orbited Earth 3,920 times, traveling nearly 104 million miles. They launched to the space station on April 8. This mission marked the first spaceflight for both Kim and Zubritsky, while Ryzhikov completed his third journey to space, logging a total of 603 days in space.

While aboard the orbiting laboratory, Kim contributed to a wide range of scientific investigations and technology demonstrations. He studied the behavior of bioprinted tissues containing blood vessels in microgravity for an experiment helping advance space-based tissue production to treat patients on Earth. He also evaluated the remote command of multiple robots in space for the Surface Avatar study, which could support the development of robotic assistants for future exploration missions. Additionally, Kim worked on developing in-space manufacturing of DNA-mimicking nanomaterials, which could improve drug delivery technologies and support emerging therapeutics and regenerative medicine.

Following post-landing medical checks, the crew will return to the recovery staging area in Karaganda, Kazakhstan. Kim will then board a NASA aircraft bound for the agency’s Johnson Space Center in Houston.

For more than 25 years, people have lived and worked continuously aboard the International Space Station, advancing scientific knowledge and making research breakthroughs that are not possible on Earth. The station is a critical testbed for NASA to understand and overcome the challenges of long-duration spaceflight and to expand commercial opportunities in low Earth orbit. As commercial companies concentrate on providing human space transportation services and destinations as part of a robust low Earth orbit economy, NASA is focusing its resources on deep space missions to the Moon as part of the Artemis campaign in preparation for future human missions to Mars.
