Live coverage: Vega rocket launches with LISA Pathfinder

Overcoming a dynamic and stormy weather pattern in Central Florida, SpaceX launched a Falcon 9 rocket from Cape Canaveral with the Israeli-owned Amos 17 commercial communications satellite Tuesday at 7:23 p.m. EDT (2323 GMT).

Arianespace’s third Ariane 5 launch of the year was set liftoff Friday from Kourou, French Guiana, but an issue with a sensor on the rocket’s first stage liquid hydrogen tank caused officials to scrub the launch attempt. The Ariane 5 is poised to carry three U.S.-built commercial satellites into orbit, while testing a few rocket upgrades, including a modified fairing needed for the launch of the James Webb Space Telescope next year.

The European Space Agency has cinched an agreement with Arianespace for the October 2018 launch of the James Webb Space Telescope aboard an Ariane 5 rocket, which will dispatch the nearly $10 billion observatory on a bold mission that promises to rewrite astronomy textbooks.
