California's skies are regularly peppered with the bright trails of rockets blasting off from the Vandenberg Air Force Base near Lompoc. The launch was first delayed by five minutes, then it was scrubbed altogether less than 10 minutes to takeoff.
When the rocket finally blasts off from the air base along the Central Coast, it should be visible throughout Southern California within minutes of the launch, according to the company.
The rocket had been scheduled to launch at 5:44 p.m. from the military base in Santa Barbara County.
Wednesday was the fourth time the mission has been delayed.
The launch was scrubbed once already this week - on Tuesday afternoon - because of high winds in the area. However, that launch was scrubbed due to a hydrogen leak (the second time in about two weeks), but luckily Mother Nature stepped in with an all natural light show.
All systems are a go - as the Delta IV Heavy Rocket prepares for lift-off tonight at 5:49 pm. ULA has launched 27 payloads for the National Reconnaissance Office over the past 12 years.
As of Thursday afternoon, the National Weather Service said the object was likely a meteor.
Many in California are used to seeing unusual bursts of light after SpaceX rocket launches but that does not appear to be the case this time.
