Live coverage: 400th Proton rocket takes off with Russian satellite

A Russian military communications satellite launched Friday from the Baikonur Cosmodrome in Kazakhstan, riding a Proton rocket and Breeze M upper stage into orbit on just the second Proton flight this year, the lowest annual flight rate for Russia’s most powerful operational launcher since the 1960s.

A Soyuz rocket and Progress supply ship packed with nearly 3 tons of cargo, provisions and fuel for the International Space Station rolled out to a launch pad at the Baikonur Cosmodrome in Kazakhstan on Monday.

The final flight of a Delta 2 rocket, a mainstay of the U.S. launch industry for nearly 30 years, began at 6:02 a.m. PDT (9:02 a.m. EDT; 1302 GMT) from Vandenberg Air Force Base in California with NASA’s ICESat 2 Earth science satellite.
