China launches hack-proof communications satellite [S&T, IR]

  • China launched the world’s first quantum satellite, which will help it establish “hack-proof” communications between space and the ground, the latest advance in an ambitious space programme.
  • The programme is a priority as President Xi Jinping has urged China to establish itself as a space power, and apart from its civilian ambitions, it has tested anti- satellite missiles.
  • The Quantum Experiments at Space Scale, or QUESS, satellite, in its two-year mission, is designed to establish ‘hack-proof’ quantum communications by transmitting uncrackable keys from space to the ground.
  • Quantum communication boasts ultra-high security as a quantum photon can neither be separated nor duplicated.
  • It is hence impossible to wiretap, intercept or crack the information transmitted through it.
  • The satellite will enable secure communications between Beijing and Urumqi, referring to the capital of China’s violence-prone far western region of Xinjiang, where the government says it is battling an Islamist insurgency.
  • The newly-launched satellite marks a transition in China’s role – from a follower in classic information technology development to one of the leaders guiding future achievements.
  • China insists its space programme is for peaceful purposes, but the US Defense Department has highlighted its increasing space capabilities, saying it was pursuing activities aimed to prevent adversaries from using space-based assets in a crisis.
