Live coverage: SpaceX launches 60 more Starlink satellites

A Chinese rocket placed three experimental military surveillance satellites in orbit Friday, the second set of related triplets launched in less than two months.

Two astronauts floated outside the International Space Station early Friday for the first of four planned spacewalks to wrap up a complex multi-year job to replace 48 aging batteries in the lab’s solar power system with 24 more powerful lithium-ion units.

A second satellite duo for Beijing Space View Technology successfully launched Tuesday atop a Long March 2D rocket, doubling the commercial company’s high-resolution imaging capacity for sale on the global market.
