SpaceX rocket launches satellites for the Starlink internet constellation

  • The Falcon 9 booster carried 53 satellites for the Starlink internet constellation after blasting off from California.
  • All the satellites were successfully deployed into the orbit by the rocket

Starlink

  • It is a space-based system that SpaceX has been building for years to bring internet access to underserved areas of the world
  • Aim: building a low-cost, satellite-based broadband network capable of delivering internet access to the entire globe.
  • SpaceX intends to put a “constellation” of satellites in low earth orbit, thereby providing high-speed, cable-like internet to every corner of the planet.
  • SpaceX will need to launch 4,425 satellites into orbit to achieve its desired coverage.

Benefits of Satellite internet

  • Broadband-level speeds are possible.
  • Ubiquitous (available everywhere)
  • In comparison to mobile hotspots, it is less expensive.
  • Quick post-disaster recovery
  • Satellite internet does not require a phone line.
  • Because satellite internet connections can withstand large bandwidth utilisation, multiple users or "peak use hours" do not harm internet speed or quality.

Associated Challenges

  • Long latency
  • Slower than fibre and cable
  • Weather-related vulnerability
  • VPN is not supported.
  • Vulnerable to Solar winds in space
