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

Russian engineers will replace rocket engines on two Soyuz rockets assigned to send a batch of supplies and the next crew to the International Space Station after an investigation revealed foreign objects or a manufacturing defect led to the crash of a Progress cargo craft on launch in December, according to Russian media reports and a statement from the Russian space agency.

SpaceX is preparing for the next launch of a Falcon 9 rocket, set for blastoff from the Kennedy Space Center in Florida with the EchoStar 23 television broadcast satellite destined to cover Brazil. The rocket’s static fire test, a major milestone in any SpaceX launch campaign, was performed Thursday.

While a SpaceX Dragon cargo ship closed in on the International Space Station early Sunday, a Russian Soyuz spacecraft blasted off from frigid Kazakhstan, boosting a fresh three-man crew into orbit for a two-day flight to the lab complex.
