Shenzhou-17 Crew Set to Return from China's Tiangong Space Station

The Shenzhou-17 crew is scheduled to return to Earth from China's Tiangong space station on April 30, 2024, after completing a six-month orbital assignment. During their stay, the Tianzhou-8 cargo ship and the Shenzhou-19 crewed spaceship are also set to arrive at the space station.

One of the key objectives of the mission was to establish a stable 'self-circulating aquatic ecosystem' in orbit using zebrafish and hornwort, with the goal of achieving a significant development in cultivating vertebrates in space. This marks China's first in-orbit aquatic ecology project. Small fish species like zebrafish and medaka have frequently been used in space research to study bone loss and muscle atrophy under microgravity conditions.

Why this matters: The successful cultivation of vertebrates in space could have significant implications for long-duration space missions and the establishment of self-sustaining life support systems. The research conducted on the Tiangong space station contributes to advancements in various fields, including materials science, biotechnology, and human health.

China has conducted over 130 science and design projects on the Tiangong space station, involving researchers from 500 Chinese and international institutions. These space experiments have supported the development of various technologies, such as alloy materials for nuclear power plants, high-performance semiconductor alloy materials, an artificial vascular tissue chip, and research on the prevention and treatment of bone diseases.

The Shenzhou-17 crew's return marks another milestone in China's rapidly advancing space program. The successful completion of their mission and the ongoing research on the Tiangong space station demonstrate China's commitment to expanding its capabilities in space exploration and scientific research. As the country continues to make progress in this field, the insights gained from these missions are expected to contribute to technological advancements and our understanding of the effects of microgravity on living organisms.
