Live coverage: SpaceX supply ship returns to Earth

A Russian Soyuz rocket and Progress resupply freighter are set for liftoff Monday on an accelerated, less-than-four-hour rendezvous with the International Space Station after last-minute launch scrubs prevented two similar fast-track approach attempts in recent months.

Forecasters predict near-ideal weather conditions Monday night for the first launch at Cape Canaveral this year, when SpaceX plans to send another 60 Starlink broadband satellites into orbit atop a Falcon 9 rocket.

United Launch Alliance called off the planned liftoff of a Delta 4-Heavy rocket and a classified National Reconnaissance Office spy satellite from Vandenberg Air Force Base in California on Wednesday after indications of elevated hydrogen concentrations around one of the launcher’s main engines. Three previous launch attempts were scrubbed by technical concerns and bad weather.
