The biological and life science experiment samples carried aboard the Shenzhou-20 spacecraft have been successfully transferred to China's space station, according to the Technology and Engineering Center for Space Utilization (CSU) under the Chinese Academy of Sciences.

The astronauts have completed the in-orbit installation of the samples and started science experiments, having obtained a number of experimental data along with imaging and video records. All experimental subjects, including planarians, zebrafish and streptomyces, are in good condition, the CSU said Friday.

The experiment studying microgravity and space radiation effects on planarian regeneration has been proceeding as planned, with the planarians observed in a relaxed state.

The research studying the regulatory mechanisms of protein homeostasis in weightlessness-induced bone loss and myocardial remodeling is underway, with aquarium lighting tests being carried out and the experiment images and videos being transmitted back to Earth.

"The circulating pump for zebrafish experiment has turned on as scheduled. For now, dissolved oxygen levels, water temperature, PH value and module internal pressure of the experiment remain within normal ranges, with zebrafish and ceratophyllum in good condition," said Wang Hongfei, a researcher of the China Academy of Sciences' Technology and Engineering Center for Space Utilization.

The research exploring the effect mechanism of microgravity on microorganisms has completed microscopic focus calibration and streptomyces sample imaging, and the streptomyces are in good condition.

During their in-orbit stay, the Shenzhou-20 crew will also conduct research across multiple disciplines, including space life sciences, microgravity physics, and new space technology.

Planned experiments include vascularized brain organoid chip cultivation, studies on the non-equilibrium dynamics of soft matter, and research on high-temperature superconducting materials.

China successfully launched the Shenzhou-20 crewed spaceship on Thursday, sending three astronauts to its orbiting space station for a six-month mission.
