📝 Preparations and Technical Highlights
The transfer of the ~60-meter-tall, 40-plus-ton combination on a mobile launch platform along 1,500 meters of seamless track took about 70 minutes. This move signifies the mission's transition from preparation to the final launch phase.
Extensive preparations were made to ensure mission success. The launch site conducted comprehensive equipment maintenance and contingency drills. The Long March-2F Y21 rocket incorporates 16 technical improvements, including a fully upgraded optical navigation system and enhanced redundancy for the inertial measurement unit, improving flight reliability. The launch tower's sealing and the fairing's air conditioning system were also upgraded to counter harsh winter weather.
China's "roll-backup, launch-one-reserve-one" model ensures continuous mission readiness. While Shenzhou-21 is prepared for launch, the Shenzhou-22 spacecraft and its rocket are on standby for emergency rescue. The current Shenzhou-20 crew aboard the space station has also conducted rendezvous and docking training in preparation for the new arrival.
The Shenzhou-21 mission demonstrates the maturity and reliability of China's human spaceflight capabilities. With the final preparations underway, the launch will be a significant event.
I hope this overview is helpful. Would you be interested in more details about the astronauts or the specific experiments they will conduct on the space station?
