Vice President Mike Pence was at the Cape for the launch Tuesday and announced President Donald Trump's plans to order the creation of a new military Space Command.
Meanwhile, Blue Origin is now targeting a Friday launch for its resuable New Shepard rocket and space capsule.
SpaceX's Falcon 9 rocket, carrying a roughly $500 million global positioning system (GPS) satellite built by Lockheed Martin Corp, was due to take off from Florida's Cape Canaveral shortly after 9:30 a.m. local time (1730 GMT), but was stopped minutes before takeoff. Blue Origin, too, said it meant to fly the tenth mission of its New Shepard Launch system from West Texas.
SpaceX's Falcon 9 launch from Florida was delayed by a technical issue involving its rocket sensors.
Tuesday's 9:11 a.m. launch window was initially delayed before it was aborted altogether.
Yesterday - Tuesday, December 18th - was supposed to be a marquee day for space agencies and private spaceflight companies around the world.
"Standing down from today's launch attempt of GPS III SV01 to further evaluate out of family reading on first stage sensors; will confirm a new launch date once complete", they said in a Twitter update. 2 is also scheduled to launch a communications satellite for the Indian Air Force on Wednesday, from the Satish Dhawan Space Center.
Tuesday to be a pretty unbelievable day of rocket launches, with SpaceX, Arianespace, and United Launch Alliance all on the pad for their final orbital missions of 2019. Liftoff was scheduled for 11:37 a.m. EST from Arianespace's South American launch facility in French Guiana. It's unclear when the next window after Wednesday will be if that launch window doesn't work out. Attempts to launch separate missions both ended with the rockets and their payloads safe - but still on the ground. The satellite is nicknamed "Vespucci" after America's namesake explorer Amerigo Vespucci.
France's Arianespace is the third to launch.
Finally, a Russian Soyuz spacecraft will return to Earth with three members of the International Space Station's crew tonight.
