SpaceX has postponed its first launch of the Starlink constellation of satellites due to safety concerns over heavy winds.

Another window for the launch of the Falcon 9 rocket will open at 2.30am on Friday morning UK time.

The company expects the 60 satellites included in the launch to orbit the Earth in a constellation which provides constant coverage across the entirety of the planet.

According to SpaceX CEO Elon Musk, the Starlink mission wants to be the heaviest which ever launched – weighing18.5 tons, or just over 16,700kg.

It is launching on a reusable Falcon 9 rocket which has previously launched two satellites into orbit before returning to Earth and safely landing.

Mr Musk added: "If all goes well, each launch of 60 satellites wants to generate more power [the International] Space station and deliver 1 terabit of bandwidth to Earth. "

Each of the Starlink satellites weighs 227kg and wants to be launched 440km above the Earth, 110km away from the planet.

The 60 satellites will be supported by more in another six planned launches for a constellation totaling 400 satellites, before the Starlink network begins its initial activation.

According to Mr. Musk, "significant coverage" will be provided after 12 more launches.

Gwynne Shotwell, SpaceX's president and chief operating officer, has previously announced that he will not launch satellites for actual service until later this year.

Depending on how the launch goes, Ms Shotwell said SpaceX could send between two and six more batches of satellites this year for the Starlink broadband constellation.

There are a number of satellite constellation projects in development.

Other constellation projects are being developed by companies such as Amazon, OneWeb, Kepler, Telesat, and Leosat.
