Live coverage: SpaceX launches another batch of Starlink satellites

An all-veteran crew of four astronauts jetted into NASA’s Kennedy Space Center Friday for the final few days of rehearsals, briefings, and relaxation before blasting off Thursday bound for a six-month stint on the International Space Station.

When the countdown hit zero last Friday and the engines powering a previously flown Falcon 9 first stage roared to life for takeoff, the four astronauts strapped into a SpaceX Crew Dragon some 21 stories up started laughing.

Presenting the results of an inquiry into a European Vega rocket failure last month, officials said Friday that misleading instructions and inadequate preflight checks caused teams to overlook wrongly-installed cables on the launcher’s upper stage steering system. Arianespace aims to resume Vega launches before the end of March.
