China launches second Tiangong space station module

China has successfully launched the second of three modules that will eventually make up its Tiangong space station. On Sunday at 2:22 PM local time (2:22 AM ET), the Wentian “Quest for the Heavens” module lifted off from the country’s Wenchang spaceport atop a Long March 5B rocket, Reuters reports. With the launch a “complete success,” Wentian is expected to rendezvous with the Tiangong space station later today.
