Facebook's 2Africa to Become World's Longest Subsea Cable

  • Facebook has announced a new segment of subsea cable called 2Africa Pearls, which connects three continents - Africa, Europe, and Asia. This extension will bring the total length of the 2Africa cable system to more than 45,000 km, making it the longest subsea cable system ever deployed.
  • The 2Africa initiative's goal, as its name suggests, is to provide internet connectivity to people in Africa, which is currently the world's least connected continent.
  • The 2Africa subsea cable system will provide nearly three times the total network capacity of all the subsea cables serving Africa today. With 2Africa, the social media giant had planned to increase connectivity to 1.2 billion people.

NASA's Lucy Mission

  • American Space Agency, NASA, is set to send its first spacecraft to study Jupiter's Trojan asteroids.
  • Spacecraft will be launched from "Cape Canaveral Space Force Station, Florida" on October 16, 2021.
  • This spacecraft would obtain new insights into the formation of solar system 4.5 billion years ago.
  • The spacecraft has been named as Lucy. It was named after an ancient fossil which provided insights into the evolution of human species.
  • Mission Lucy will be launched with the objective of investigating the group of rocky bodies that are circling the sun in two swarms- one preceding Jupiter and the other trailing behind it.
  • Trojans are small celestial bodies or asteroids, sharing the orbit of larger one. They remain in a stable orbit, nearly 60° ahead or behind the main body. The Jupiter trojans, commonly called Trojan asteroids or simply Trojans, are a large group of asteroids that share the planet Jupiter's orbit around the sun.
