SpaceX plans to have 12,000 satellites by 2025
Frederick Klettan astrophysicist from the Belgian Royal Observatory, has already explained this intriguing phenomenon to us: “These satellites are in orbit, at an altitude of almost 500 km. These satellites will remain in orbit for months or even years. “The goal is to provide full geographic coverage of the terrestrial sphere for Internet connections,” concluded Frederick. Klett.
According star link858 such devices have already been launched. To meet its commercial goals, SpaceX plans to have 12,000 satellites by around 2025, and eventually 42,000. The Falcon-9 rocket is a reusable launcher (to reduce costs) that has been in place since 2010.
