Live coverage: Ariane 5 blasts off with two Intelsat satellites

Sixty more satellites for SpaceX’s Starlink global Internet network streaked into orbit Monday night from Cape Canaveral, including one spacecraft to test an experimental dark coating to address scientists’ concerns that the thousands of the quarter-ton, flat-panel satellites will impede astronomical observations.

Mounted on a mobile platform, a European Ariane 5 rocket followed dual rail tracks across the Guiana Space Center in South America on the way to its jungle launch complex Monday, a day before its scheduled blastoff with four satellites to expand Europe’s independent navigation network.

Ground controllers could try to salvage a Chinese television broadcasting satellite deployed in a lower-than-planned orbit Sunday by a Long March 3B rocket.
