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

The launch of a Boeing-built Mexican communications satellite on a Proton rocket has been postponed after engineers discovered an anomaly on a similar spacecraft.

A Russian satellite launched Tuesday from the Baikonur Cosmodrome in Kazakhstan, riding a Proton booster and Block DM upper stage toward a position in geostationary orbit to provide weather observations over Siberia, other parts of Russia’s Far East, and the Asia-Pacific region.

Look back on last week’s launch of a Russian Proton rocket from Kazakhstan with the EchoStar 21 communications satellite, a commercial craft designed to beam broadband connectivity to customers across Europe.
