ISRO's Shukrayaan

ISRO’S SHUKRAYAAN:

The Indian Space Research Organisation (ISRO) has short-listed 20 space-based experiment proposals for its proposed Venus orbiter mission 'Shukrayaan'.

About Shukrayaan: It is a mission to study Venus for more than four years.

Scientific objectives:

  • Investigation of the surface processes and shallow subsurface stratigraphy; and solar wind interaction with Venusian Ionosphere, and studying the structure, composition and dynamics of the atmosphere.
  • The satellite is planned to be launched onboard GSLV Mk II rocket.
  • The proposed orbit is likely to be a lower apoapsis (farthest point).

Why study Venus?

  • Venus is often described as the “twin sister” of the Earth because of the similarities in size, mass, density, bulk composition and gravity.
  • It is believed that both planets share a common origin, forming at the same time out of a condensing nebulosity around 4.5 billion years ago.
  • Venus is around 30 per cent closer to the Sun as compared to Earth resulting in much higher solar flux.
