SpaceX launched what has been a top secret mission just before dusk on Sunday, not releasing the contents of its payload and changing its original mission name.

At 5:28 p.m. SpaceX launched the Optus-X satellite for Australian telecommunication company, Optus. The rocket lifted off from Kennedy Space Center's Pad 39A, traveling on a due east trajectory. With clouds in the area, most on the Space Coast only saw a short glow before the rocket disappeared.

SpaceX is set for a Sunday evening launch from Kennedy Space Center with a Monday launch attempt from Cape Canaveral on tap.

Space Coast sure is living up to its nickname. Another SpaceX rocket launch will potentially lift off— weather-permitting, it should be a pretty view.

MERRITT ISLAND, Fla. - SpaceX is set to launch a Falcon 9 rocket Sunday afternoon for its TD7 mission to a geosynchronous transfer from orbit. The launch is slated for 4:29 p.m. at Kennedy Space Center. The slated launch will be the 16th flight for the Falcon 9 first stage booster supporting the mission.

Who's up for two launches this week? Weather permitting, two SpaceX rockets should be visible from the Treasure and Space Coasts after liftoff.

No further information is available on this spacecraft. As of Monday morning, SpaceX has confirmed the launch, referring to it as TD7. The mission is set to liftoff atop a Falcon 9 at 5:28 p.
