Space X wants to beam Internet back to Earth
One the one hand it would be nice to have cheap and very fast internet. On the other hand that is a lot of satellites to put into orbit.
SpaceX is preparing to hit another orbital milestone with the launch of a pair of experimental satellites on Sunday that are designed to beam an ultrafast, lag-free Internet connection down to Earth.The test satellites, dubbed Microsat-2a and Microsat-2b, are a part of a years-long plan by chief executive Elon Musk to create a fleet of orbiting devices to blanket the globe in wireless broadband connectivity. SpaceX ultimately intends to put about 12,000 broadband satellites in low Earth orbit, and Sunday’s payload will mark the company’s first attempt at realizing the dream. The initial satellites in the network are expected to come online next year.To ensure consistent coverage, providers of next-gen satellite broadband will need to put up many more satellites, as well as develop accurate tracking technology that lets devices on the ground communicate with them without missing a beat. And they’ll need to use radio frequencies that are known for their low-lag physical properties. SpaceX’s network plans to use airwaves in the Ka-, Ku- and V-bands — with about 4,400 K-band satellites and more than 7,000 V-band satellites.
Some critics of satellite broadband have warned of the risk of creating more debris in space that could prove harmful to other space operations. In October, a pair of U.S. senators sent a letter to the Federal Communications Commission asking the FCC to coordinate with other federal agencies on space junk in light of the plans by SpaceX and others to add thousands of new satellites to Earth’s orbit.
