Launch no earlier than 5th\/6th. Only one chance to get it right \u2026<\/p>\n<p>\u2014 Elon Musk (@elonmusk) July 4, 2017<\/p>\n<\/blockquote>\n<p><script async=\"\" src=\"\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<p>The trigger of Monday\u2019s abort was not immediately known, but an unplanned hold at the same point in a countdown Sunday was caused by a software error during a final check of the rocket\u2019s guidance, navigation and control instrumentation.<\/p>\n<p>SpaceX said they cleared that problem, and engineers pressed ahead with another attempt Monday to send the heavyweight nearly 7.5-ton Intelsat 35 relay and broadcasting satellite into orbit.<\/p>\n<p>Stormy weather to the west of launch pad 39A at the Florida spaceport delayed the targeted launch time 58 minutes to 8:35 p.m. EDT Monday (0035 GMT Tuesday), the end of the day\u2019s launch window.<\/p>\n<p>Using a computer-controlled automatic sequencer, the launch team loaded the Falcon 9 rocket with super-chilled, densified RP-1 kerosene and liquid oxygen propellants in the final hour of the countdown.<\/p>\n<p>No technical problems were noted by SpaceX engineers as the final minutes ticked toward liftoff, until the countdown stopped at T-minus 10 seconds. Without any time left in the launch window, the hold led to an automatic scrub.<\/p>\n<p>Engineers will comb through data to determine source of the problem, and identify a fix, SpaceX said.<\/p>\n<p>\u201cWe have all the telemetry coming off of the rocket, so we\u2019ve got plenty of information, but they\u2019re taking their time right now to understand what system they\u2019re really looking at that would be the cause of the hold,\u201d said John Insprucker, SpaceX\u2019s Falcon 9 principal integration engineer, who provided live launch commentary on the company\u2019s webcast.<\/p>\n<p>SpaceX initially said it could try a third day in a row Tuesday \u2014 Independence Day \u2014 to launch the Falcon 9 rocket, but officials said a few hours after Monday\u2019s scrub that the next liftoff attempt would slip until later in the week.<\/p>\n<p>\u201cWe had an extended countdown today,\u201d Insprucker said as SpaceX\u2019s webcast signed off. \u201cWe had to wait for the weather, and we got to T-minus 10 seconds before we had a hold, once again, called by the automated abort criteria.<\/p>\n<p>\u201cWe were not able to recycle because we were out of the window,\u201d he said.<\/p>\n<p>SpaceX is going for its third Falcon 9 launch in less than two weeks, and the second from pad 39A in that span. The Air Force-run Eastern Range was expected to be unavailable for launch operations for a couple of weeks beginning soon after the July 4 holiday.<\/p>\n<p>Intelsat\u2019s senior vice president of space systems, Ken Lee, said additional engineers came to Cape Canaveral to prepare for the Intelsat 35e launch, and ground teams worked around-the-clock in shifts ahead of the Falcon 9\u2019s first launch attempt Sunday.<\/p>\n<p>Once the Falcon 9 takes off with Intelsat 35e, SpaceX\u2019s launch cadence will slow for a few weeks. The company\u2019s next mission is scheduled to launch Aug. 10 from Florida on a space station resupply run.<\/p>\n<p><b><i>Email the author.<\/i><\/b><\/p>\n<p><em><strong>Follow Stephen Clark on Twitter: @StephenClark1.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Updated at 4:30 a.m. EDT (0830 GMT) July 4.
