A week after world’s biggest rocket launch, SpaceX is planning to send another satellite in space this week and this time it’s the world’s first global internet satellite.

The project was unveiled three years ago in 2015 that aimed for a constellation of satellites in orbit around the Earth and would provide internet access to everyone and everywhere. The plan involved to launch more than 4,000 internet satellites that will create a network capable of transmitting anywhere.

The company’s ‘Starlink’ network will launch its first test satellites into orbit this Saturday on February 17. Though Elon Musk’s SpaceX has not yet verified if the Starlink prototypes are on board, it has said that the launch will include Paz, a 1,360kg radar observation satellite by the Spanish company hisdeSAT.

Another secret object was sent to space along with Tesla Roadster

According to Geek Wire, Saturday’s launch will include two satellites to be sent to orbit, Microsat 2a and 2b on the company’s next Falcon 9 rocket launch. Connections will be tested with ground station in Washington, Texas and California, along with receivers in mobile vans spread across the country, as per the documents filed with the Federal Communication Commission (FCC).

If the tests are completely successful, SpaceX will launch its first internet satellite late this year with limited internet network. This network would contain around 800 satellites covering the United States, later expanding it to the rest of the world.

Moreover, SpaceX is not the sole firm with plans for global internet satellites being sent to space. Boeing, OneWeb, and Samsung along with few others have also plans to launch their satellite constellation within few years, reported Popular mechanics.
