The tweet revealed a targetted launch date of January 6 at 02:19 UTC from Pad 40 at Cape Canaveral Air Force Station in Florida.
SpaceX plans to operate its initial batch of 1,584 satellites 341 miles (549km) above the Earth, hovering much lower than traditional communications satellites.

SpaceX has efficiently fired up a Falcon 9 rocket for the primary time in 2020, setting the corporate up for the first of doubtless dozens of Starlink launches over the following 12 months. EST (02:19 GMT) will break the record for the number of in-orbit satellites owned by one company, and ultimately boost global internet access.
Elon Musk's aerospace company, SpaceX, will launch its third Starlink satellite at mission tonight, January 6, in what will be a bid to send 60 more operational satellites into Earth's orbit, taking the Starlink satellite total to 180.
The satellites are hard to see without a telescope but astronomers said that with instruments they are bright enough to get in the way. OneWeb launched its first six satellites in 2019. And one of the 60 satellites that launched tonight features an experimental coating created to reduce the object's brightness.
Astronomers say the proliferation of the bright metallic satellites could seriously degrade the night view, interfering with both optical and radio astronomy.
SpaceX says its satellite constellation will be operational for Canada and the northern U.S. by next year. And Canada by the end of 2020, with up to 20 more launches of lots of similarly sized Starlink satellites that will take place during the course of the year. SpaceX's Gwynne Shotwell has said that coverage could begin sometime this year, but the company has not yet announced pricing for its new service. For instance, Patricia Cooper, SpaceX's vice president of satellite government affairs, is presenting a paper during the special AAS session on Wednesday.
To address the concerns, SpaceX is experimenting with coatings that would reduce the satellites' reflectivity.
"It'll be some trial and error but we'll fix it".
