Live coverage: SpaceX cargo ship arrives at space station

SpaceX and SES, an international communications satellite operator based in Luxembourg, have agreed to place the SES 10 television relay craft aboard the first launch of a reused “flight-proven” Falcon 9 rocket from Cape Canaveral as soon as October, the companies announced Tuesday.

SpaceX test-fired a reused Falcon 9 booster Monday at NASA’s Kennedy Space Center in Florida, checking the rocket’s readiness for a planned liftoff Saturday with an Airbus-built commercial communications satellite.

A Russian Soyuz booster lifted off Friday from Kazakhstan on a complex mission to deploy 73 satellites into three different orbits, including a Russian spacecraft to locate forest fires, 48 CubeSats for Planet’s global Earth observation fleet, and eight nanosatellites for Spire Global’s commercial weather network.
