Live coverage: International Space Station crew lands in Kazakhstan

Russian and European teams at the Guiana Space Center in South America plan to detach a UAE spy satellite from its Soyuz launcher to replace the rocket’s Fregat upper stage, forcing a likely delay until April from the mission’s original launch date of Friday.

A Russian Soyuz spacecraft carrying three space station crew members hurtled back to Earth Thursday, completing a fiery plunge back through the atmosphere before settling to a frigid touchdown on the snowy steppe of Kazakhstan to close out a 139-day mission.

This is the launch timeline to be followed by the Atlas 5 rocket’s ascent into orbit from Cape Canaveral with NASA’s Tracking and Data Relay Satellite-M. Launch is scheduled for Friday at 8:03 a.m. EDT (1203 GMT).
