Company SpaceX performs fueling of the launch vehicle, the Falcon 9 test before manned flight spacecraft Crew Dragon, NASA will broadcast live.

The launch of the Falcon 9 spacecraft Crew Dragon launch site at Cape Canaveral is scheduled for 22:22 GMT on Saturday. Aboard the ISS will go the astronauts Doug Hurley and Bob Behnken.

After about the beginning of the fueling of the rocket fuel system has been activated crew evacuation in case of emergency start. To date, the complete filling of the first stage.

To provide thrust, the Falcon 9 uses kerosene RP-1 and liquid oxygen. Technology SpaceX involves the use of chilled fuel to generate more thrust at the start, so filling the rocket must occur no later than 35 minutes before the start. In 2016 the Falcon 9 exploded during refueling in preparation for the launch Israeli communications satellite. After the accident it was reported that a few months before the explosion, the Commission of experts of NASA, expressed concern about the refueling rocket fuel after the crew took their places, but SpaceX was able to insist that it is safe.
