Q. The “Project NETRA” is often seen in news is related to which of the following?

[A] Early warning system in space to detect debris

[B] Earth observation satellite constellation system

[C] Early warning system of Tsunamis

[D] Low Altitude Defense System

Answer: A
Notes:

The Indian Space Research Organisation (ISRO) initiated ‘Project NETRA’ – an early warning system in space to detect debris and other hazards to Indian satellites. 

  • The space agency says our SSA (space situational awareness) will first be for low-earth orbits or LEO which have remote-sensing spacecraft.  
  • Under NETRA, or Network for space object Tracking and Analysis, the ISRO plans to put up many observational facilities: connected radars, telescopes; data processing units and a control centre.  
  • They can, among others, spot, track and catalogue objects as small as 10 cm, up to a range of 3,400 km and equal to a space orbit of around 2,000 km.
