China successfully docked a second laboratory module to its under-construction space station, the China Manned Space Agency (CMSA) said Monday, as the country takes a step closer to completing its orbital outpost by the end of the year.
The Wentian module was launched atop a Long March 5B rocket from Hainan Island at 2:22 p.m. local time on Sunday.
