Imagine living and working hundreds of miles above Earth for more than 50 days. That has been the reality for China's Shenzhou XX crew-Chen Dong, Chen Zhongrui, and Wang Jie-currently aboard the Tiangong Space Station conducting vital scientific and medical research.

In a video released Monday by China Central Television (CCTV), the astronauts were shown carrying out a full slate of experiments, maintenance tasks, and health protocols, which are integral to China's broader space exploration goals. All three crew members remain in good condition, and mission activities are progressing steadily, according to the report.

Led by veteran astronaut Chen Dong, the trio launched on April 24 for a six-month mission. Recent activities have focused heavily on space medicine. Investigations include how microgravity impacts cognitive function, interpersonal coordination, spatial perception, and individual awareness-factors that directly influence mission safety during complex operations such as spacewalks.

In parallel, the astronauts performed vascular ultrasound assessments to monitor cardiovascular health and employed specialized tools to study fine motor control while handling equipment. These assessments aim to deepen understanding of how extended spaceflight alters neuromuscular responses.

Their life science work centers on how microgravity affects microorganisms, specifically investigating the growth and metabolic behavior of Streptomyces bacteria within Tiangong's biotechnology experiment rack. This experiment could yield new insights into microbial adaptation and enable future pharmaceutical innovations in space environments.

The crew has been carefully preserving liquid culture samples from the experiment for return to Earth for further analysis.

As part of their daily routine, the astronauts also follow a strict physical training regimen, including treadmill exercise, to combat the physical deterioration caused by weightlessness. Health checks include heart monitoring, blood pressure measurements, and assessments guided by traditional Chinese medicine techniques.

According to the China Manned Space Agency, the Tiangong Space Station has supported more than 200 scientific projects to date. Nearly 2 tons of experimental materials and devices have been delivered into orbit, with close to 100 samples already returned to Earth.
