JWST is the largest-ever space telescope expected to launch in 2018. It will help:

  • A wide range of investigations in the fields of astronomy and cosmology.
  • Understand the origins of the universe
  • Evolution of Solar System
  • Search for signs of life on faraway planets
  • Analyze the atmospheres of exoplanets that pass in front of their stars.

Key Aspects

  • James Webb Space Telescope (JWST) is considered to be the successor to NASA’s 26-year-old Hubble Space Telescope.
  • In October 2018, Ariane 5 rocket will launch it from French Guiana.
  • Webb telescope will be used to observe distant objects in the world.
  • Total area of 270 square feet made from 18 hexagonal mirrors coated with beryllium and gold to collect the infrared readings.
  • Reflecting mirrors having diameter of 6.5m.
  • NASA’s engineers and technicians successfully completed the first important visual measurement of Webb’s fully collected primary mirror- the Centre of Curvature test to measure the mirror’s shape.
  • Formed through international collaboration of 17 countries including:

    • NASA
    • European Space Agency (ESA)
    • Canadian Space Agency (CSA)
  • $8.7 billion project
