Indonesia and Elon Musk’s rocket company SpaceX on Monday launched the country’s largest telecommunication satellite from the United States, in a $540 million project intended to link up remote corners of the archipelago to the internet.

Approximately two-thirds of Indonesia’s 280 million people already use the internet, but connectivity is limited in the Southeast Asian country’s remote, underdeveloped eastern islands.

“Satellite technology will accelerate internet access to villages in areas that cannot be reached by fiber optics in the next 10 years,” Mahfud MD, senior Indonesian minister, said in a statement ahead of the launch.

Thales Alenia Space built the 4.5-tonne Satellite of the Republic of Indonesia (SATRIA-1) and launched it into orbit from Florida using SpaceX’s Falcon 9 rocket, which then returned to an offshore site in a precision landing, Reuters reported.

The satellite will occupy the orbital slot above Indonesia’s eastern Papua region. It has a throughput capacity of 150 gigabytes per second and will provide internet access to 50,000 public service points, the Indonesian government said.

The project is a public-private partnership between the government and Indonesian satellite service provider PT Satelit Nusantara Tiga.
