Post-Launch Analysis: Long March 5 | TJSW-20 Mission (October 23, 2025)

The Long March 5 launch of the TJSW-20 satellite on October 23, 2025, marks another successful operation for China’s heavy-lift rocket program. Mission execution was flawless, with the rocket achieving precise orbital insertion and successful payload deployment, as confirmed by official reports. Technical performance data indicates nominal operation of the rocket’s YF-77 cryogenic engines and multi-stage separation systems, reinforcing the Long March 5’s reliability for high-payload missions. While the TJSW-20 satellite’s purpose remains classified—officially described as a communication technology test—its deployment validates China’s capability to handle sensitive, high-value payloads. Engineering lessons from this mission further affirm the rocket’s design robustness, critical for upcoming lunar and interplanetary endeavors. Strategically, this success bolsters China’s space autonomy and positions the Long March 5 as a cornerstone for future ambitious missions, including crewed lunar exploration and space station expansions.
