The plan is for them to dock with and then spend 30 days on board the Tiangong 2 space station testing its ability to support life. This and previous launches are seen as pointers to possible crewed missions to the Moon or Mars.
NBC calls this evidence of "the intensifying U.S.-China space rivalry... With the current U.S.-led International Space Station expected to retire in 2024, China could be the only nation left with a permanent presence in space."
But Slashdot reader mirandakatz writes, "It's not enough to build self-driving cars: we have to build the roads to accompany them. Roadside sensors might have once seemed a pipe dream, but with the advent of 5G internet infrastructure, they're not out of reach at all. And their implications span far beyond road safety, GMU researcher Brent Skorup explains at Backchannel: Cities could use sensor data for conducting traffic studies, pushing out real-time public bus alerts, increasing parking space occupancy, metering commercial loading times to prevent congestion, and enhancing pedestrian safety. There are also commercial applications for sensor data: How many cars drive by a billboard? How many people walk by a storefront per day? How many of those people have dogs? These are all questions we could easily answer with roadside sensors.
