The NBN's second satellite, Sky Muster II, is launching in a rocket that will have a unique feature — artwork with the faces of 1210 Australians.

Scheduled to launch from French Guiana Space Centre in South America in late 2016, the satellite will "help deliver fast broadband to even the most remotely located Australians, helping to bridge the digital divide between city and bush," NBN said in a statement.

NBN's first Sky Muster rocket blasts off back in October.

There are currently more than 37,000 users on NBN's interim satellite service across Australia, with NBN's goal to move them (along with new users) to the new satellite within one year of the commercial launch in May 2017.

NBN says its satellite service is designed to deliver wholesale broadband speeds of up to 25 Mbps download and up to 5 Mbps upload to retail service providers, dependent on the technology over which services are delivered to your premises and some factors outside NBN's control like your equipment quality, software, broadband plans and how your service provider designs its network.
