Development of Space Technology

PIB Summary

Development of Space Technology

Some of the new developments made in the last three years are as listed below :

  • Development of highly polished optical mirrors – for a solar coronographic mission – Aditya-L1
  • Development of large, light-weight collimators with non-cylindrical aperture – for x-ray polarimetric applications – XpoSAT mission
  • Development of indigenous silicon sensors and coatings for optical and IR spectroscopic applications – for payloads on Chandrayaan-2 mission

RESPOND programme

  • Indian Space research Organisation through the programme called RESPOND (Sponsored Research) is encouraging academia to participate in the R & D activities.
  • The  programme provides support to research projects in wide range of topics in space technology, space science and applications to universities/ institutions.

Aditya-L1 mission:

  • ISRO’s Aditya – L1 mission is similar to NASA’s Parker Solar Probe, that is to study the sun.
  • The Aditya – L1 will be inserted in a halo orbit around the Lagrangian point 1 (L1), which is 1.5 million km from the Earth.
  • Lagrangian point is a point where the attraction by the Sun and the Earth becomes equal. The point doesn’t experience gravitational force.
  • Planning to launch in 2021
  • Study of chromospheric and coronal heating, Physics of the partially ionized plasma and initiation of the CMEs and flares
  • Observe the in-situ particle and plasma environment providing data for the study of particle dynamics from the Sun.

XPoSat

  • To measure polarization (degree and direction) of X-ray photons from ~50 potential celestial sources of interest in the energy band of 5-30 keV.
  • Mission Life – 5 years, Platform – Modified IMS-2 Bus
  • • Payload – Polarimeter Instrument in X-rays (POLIX) from Raman Research Institute
  • Planning to launch in 2021

Chandrayaan-2

  • Expand technologies from Chandrayaan-1 & demonstrate newer technologies for future planetary missions.
  • Deploy a Lunar Lander-Rover capable of soft landing on a specified lunar site and deploy a Rover to carry out in-situ analysis of chemicals.
  • Carry payloads in the Orbiter craft to enhance the scientific objectives of Chandrayaan-1 with improved resolution.
  • Chandrayaan-2 Mission is planned during early 2019.
