What happened is the Chinese are preparing for a big space mission and sent a cargo spacecraft called the Tianzhou-3 to bring supplies in space for a crew who will join a mission on the Shenzhou-13, another Chinese spacecraft.
And the Tianzhou-3 successfully docked and China is calling it a complete success after the successful return of its astronauts from space.
How did they do it? Tianzhou-3 was carried on a Long March-7 Y4 rocket that blasted off at 3:10 pm from the Wenchang Spacecraft Launch Site in the southern island province of Hainan and completed the process in approximately 6.5 hours.
