SpaceX launching isn’t successful due to unknown reason and according to a report from CNET “Five, four, three, two, one, zero and lift…off,” “We’ve had a cutoff,” Diller quickly said. “Liftoff did not occur. We’ve had a launch abort. Standing by… We did not get confirmation from the first motion sensor that liftoff occurred. The flight computer is not in startup.”
“We hold the vehicle down with purpose to watch for this exact issue,” said SpaceX President Gwynne Shotwell. “Just like a pilot at the end of a runway revs the engines and looks at the gauges, we were revving the engines, we were looking at the gauges and we decided not to fly.”
On the other hand, Mashable claimed that “SpaceX has a $1.6 billion commercial contract to deliver supplies to the station. Its latest attempted mission was intended to test whether the Dragon can successfully dock there. A previous test flight in 2010 successfully launched the dragon and recovered it from orbit.
Officials at the company had made efforts to play down expectations before Saturday’s launch — predicting just a slightly greater than 50-50 chance of launching,”
