News Brief: The anxiously awaited launch of the first of SpaceX’s “last” Falcon 9 rockets will have to wait at least one more day. SpaceX CEO Elon Musk says the company’s upgraded Block 5 model “will be the last major version of the Falcon 9” before it’s retired in favor of the super-duper-sized BFR. This first Falcon 9 Block 5 rocket was due to launch the Bangabandhu Satellite-1 for Bangladesh from NASA’s Kennedy Space Center today, but SpaceX’s flight control computer automatically called a halt to the countdown at T-minus-58 seconds. There was no immediate word on the cause of the abort. Launch is now set for 4:14 p.m. ET (1:14 p.m. PT) on Friday. Check out the mission press kit, and watch for SpaceX’s next webcast.
