China successfully launched the Shenzhou-18 manned spacecraft on Thursday, marking the third crewed mission since the country’s space station entered its application and development phase. Developed by the China Academy of Space Technology (CAST), Shenzhou-18 carries significant technological upgrades that enhance its performance and mission capabilities.
“From the general technical state, there are the orbital module, the re-entry module, and the propellant module. And there are solar panels and the engines. They are consistent with the previous technological designs,” said Chen Tongxiang from CAST. “However, the biggest difference this time is the upgrade to the spacecraft’s battery, replacing the cadmium-nickel battery with a lighter and smaller lithium one that has a much longer life.”
The new lithium batteries not only reduce the spacecraft’s weight but also extend its operational lifespan, allowing for longer missions and more flexibility in space station operations. “As a manned vehicle, the Shenzhou spacecraft requires the highest safety and reliability. The upgrade to the battery has been fully verified in our space station, cargo ships, and other spacecraft,” Chen noted.
In addition to the battery upgrade, Shenzhou-18 features minor modifications aimed at improving mission efficiency and scientific output. “There are also small modifications, like a little more space for space science experiments,” Chen added.
The successful launch of Shenzhou-18 underscores China’s continued progress in its ambitious space exploration program. The mission not only advances scientific research but also enhances international cooperation and interest in space technology developments in Asia.
