Shenzhou 23 Launches Yearlong Space Mission

On Sunday, May 24, 2026, China launched the Shenzhou 23 spacecraft from the Jiuquan Launce Center in northwestern China. The spacecraft carried three astronauts, commander Zhu Yangzhu, Zhang Zhiyuan, and Lai Ka-ying. to Tiangong, the country’s space station.

At 11:08 pm (1508 GMT), the Long March 2-F rocket launched from the Jiuquan launch centre in the Gobi Desert, according to video from a state broadcaster on CCTV.

The spacecraft separated from the rocket 10 minutes later and entered orbit, as reported by the Chinese Manned Space Agency on social media. It stated, “The astronauts are in good condition, and the launch has been a complete success.”

The Shenzhou 23 docked with the Tiangong space station after a 3.5 hour flight, according to state news agency Xinhua.

Shenzhou 23 Mission

The crew will be conducting several science and application projects in materials science, life science, fluid physics, and medicine, according to state media. Additionally, they will complete an orbit rotation with the Shenzhou 21 crew, who have been at the space station for more than 200 days.

One of the Shenzhou 23 astronauts will remain on Tiangong for a year to “explore human adaptability and performance limits in long-duration spaceflight environments,” according to state media. This will be recorded as one of the world’s longest single stays in space.

Yearlong Experiement

The Shenzhou 23 year-long mission is part of the preparations for future moon missions and missions to Mars.

The astronaut for this mission has yet to be named. According to a spokesperson for the CMSA, it will depend on the Shenzhou 23 mission progress.

The primary challenges for the year-long mission include muscle wasting, bone loss density, sleep disturbances, radiation exposure, behavioral and physiological fatigue, according to astrophysicist and professor at Macquarie University in Australia, Richard de Grijs.

He added the importance of managing potential emergencies in space, as well as reliable recycling and water systems.

The country is working toward “sustained occupation” of the space station. Year-long missions are a step toward future moon and deep-space goals, according to Grijs.

“A year in orbit pushes both hardware and humas into a different operational regime compared with the shorter Shenzhou missions of the programme’s earlier phases,” he stated.

Before now, crews have not remained in orbit for more than six months.

Future Space Missions

China is testing the next release of the equipment that will help the country reach its space goals. Later this year, the country is planning an orbital test flight of the Mengzhou spacecraft that will replace the Shenzhou line and take astronauts to the Moon from China.

By 2035, Beijing plans to complete the first phase of a manned scientific base that will be names the International Lunar Research Station (ILRS).

Additionally, Beijing will welcome its first foreign astronaut from Pakistan aboard the Tiangong later this year.

Since China was excluded from the International Space Station by the U.S. due to national security concerns, it has stepped up its space program and carried out several mission to the Tiangong space station.

The Tiangong space station hosted its first crew in 2021. Tiangong means “Heavenly Palace.” In 2025, an emergency mission within the Shenzhou program returned a crew stranded on the space station after their spacecraft was damaged. Shenzhou means “Divine Vessel.”

China plans to send astronauts to the moon by 2030, according to state media. The Shenzhou 23 space mission is part of that endeavor.

This is the first space flight by an astronaut from Hong Kong. Forty-three-year-old Li Jiaying (Lai Ka-ying in Cantonese), who previously worked for the Hong Kong police.

Thirty-nine-year-old Zhu Yangzhu is a space engineer and former air force pilot Zhang Zhiyuan, who is traveling into space for the first time, is also 39.
