Live coverage: Ariane 5 blasts off with two Intelsat satellites

A Soyuz rocket is scheduled to lift off Tuesday from a launch pad in Russia’s Far East with a new Russian weather satellite and 18 secondary payloads from companies and institutions in the United States, Canada, Japan, Norway, Sweden and Germany.

Rocket Lab’s Electron booster launched six small satellites and a drag sail demonstrator to orbit Sunday from New Zealand, a success on the company’s first commercial mission that officials said should pave the way for a launch carrying NASA CubeSats next month and up to 16 flights of the light-class rocket next year.

NASA expects to spend some $5 billion underwriting development of commercial spacecraft built by Boeing and SpaceX to carry astronauts to and from the space station, ending reliance on the Russians for crew flights and lowering the average cost per seat to around $58 million.
