Live coverage: Proton fires into space with Eutelsat 9B

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).

A modest European-built spacecraft tuned to test the delicate, cutting edge technologies required to detect gravitational waves, a measurement that scientists say could yield unforeseen discoveries about the universe, is awaiting liftoff aboard a solid-fueled Vega rocket this week.

A rocket-transporting railroad car ferried a Proton rocket to its launch pad Friday at the Baikonur Cosmodrome in Kazakhstan for final checkouts and testing before the vehicle’s scheduled June 21 liftoff with the Russian-German Spektr-RG X-ray telescope.
