Live coverage: Soyuz blasts off on third mission for O3b

Four more satellites for SES Networks’ O3b broadband fleet launched Thursday aboard a Soyuz rocket. Liftoff of the Soyuz launcher from the Guiana Space Center in South America occurred at 1703 GMT (1:03 p.m. EDT).

The Italian PRISMA Earth observation satellite is set to ride a Vega launcher into a 382-mile-high (615-kilometer) orbit Thursday night from French Guiana on a mission that will take less than one hour from liftoff until spacecraft separation.

Two weeks after a launch pad fire forced a delay, a Japanese H-2B rocket lifted off Tuesday with an HTV cargo freighter to deliver upgraded batteries, experiments and provisions to the International Space Station. Liftoff from the Tanegashima Space Center occurred at 1605 GMT (12:05 p.m. EDT) Tuesday.
