Live coverage: Dragon completes space station resupply flight

NASA astronaut Nick Hague and Roscosmos cosmonaut Alexandr Gorbunov arrived in Florida on Saturday afternoon ahead of their final launch preparations. A flight readiness review occurred on Monday, Sept. 23.

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.

Unfavorable high-altitude winds above Cape Canaveral on Tuesday kept a SpaceX Falcon 9 rocket loaded with a NOAA space weather observatory on the ground another day.
