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.

SpaceX has plans to start the week with back-to-back launches from Florida and then Starship Tuesday in Texas.

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.

This is also the first time ISRO has developed a satellite that only uses the advanced Ka-band frequency, which has a range of radio frequencies between 27 and 40 gigahertz (GHz) and allows the satellite to have a higher bandwidth.

SpaceX is set to launch a satellite for the Australian telecom company Optus this afternoon (Nov. 17) from Florida's Space Coast.
