Context: Indian Solar physicist from Indian Institute of Astrophysics, Dipankar Banerjee, is selected as a Co-Investigator of NASA's PUNCH mission .

Background: NASA has selected the following two missions to advance our understanding of the Sun and its dynamic effects on space.

1.Polarimeter to Unify the Corona and Heliosphere (PUNCH)

  • Mission will focus directly on the Sun’s outer atmosphere, the corona, and how it generates the solar wind. 
  • PUNCH will image and track the solar wind as it leaves the Sun. The spacecraft also will track coronal mass ejections

2.Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites(TRACERS)

  • TRACERS will observe particles and fields at the Earth’s northern magnetic cusp region the region encircling Earth’s pole, where our planet’s magnetic field lines curve down toward Earth.
