China launched the Long March 5B rocket on which date?

The Long March 5B rocket, carrying the core module of China's Tiangong space station, was successfully launched on April 29, 2021. This launch was a pivotal moment in China's ambitious space program, marking a significant step towards establishing its permanent orbital outpost. The mission demonstrated China's growing capabilities in space exploration and technology.

• May 5, 2021 and May 10, 2021 are incorrect dates for this specific, high-profile launch.
• April 29, 2020 was the date of the Long March 5B's maiden, uncrewed test flight, which was a different mission from the one carrying the space station module. The question specifically refers to the launch of the space station module.
