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

A Russian Soyuz rocket rolled out to a launch pad Monday at the Baikonur Cosmodrome in Kazakhstan, ready for final inspections, checkouts and fueling before liftoff Thursday with a Progress supply ship bound for the International Space Station.

It will take more than 12 hours from liftoff of the European Space Agency’s ExoMars Trace Gas Orbiter until engineers verify the mission is on track for Mars after a series of critical in-space maneuvers by the Proton rocket’s Breeze M upper stage.

SpaceX launched 60 more Starlink Internet satellites Wednesday aboard a Falcon 9 rocket. Liftoff from pad 39A occurred at 3:30 p.m. EDT (1930 GMT), and the Falcon 9’s previously-flown first stage successfully landed on SpaceX’s offshore drone ship.
