Live coverage: Vega rocket launches with 53 small satellites

A layer of fog intruding on Vandenberg Air Force Base in California kept nearby observers from seeing any sign of Saturday’s predawn launch of an Atlas 5 rocket carrying a robotic NASA probe to Mars. The only images of the Atlas 5’s fiery takeoff came from remote cameras placed at the launch pad, or from distant viewing points away from the poor visibility.

Extra testing of the James Webb Space Telescope and delays in assembling the powerful observatory will push back the $10 billion mission’s launch by at least six months to early 2019, officials announced last week as the telescope successfully completed an extensive performance test inside a cryogenic vacuum chamber in Houston.

Wrapping up a two-day pursuit since launching from Cape Canaveral, a SpaceX Dragon supply ship arrived at the International Space Station Monday with more than two tons of cargo and experiments. The automated cargo freighter was captured by the station’s robotic arm at 6:25 a.m. EDT (1025 GMT).
