the successful launch of Chandrayaan-2, Indian Space Research Organisation
(ISRO) is now focussing on launching the Aditya L-1 mission.
Aditya L-1 mission is a satellite designed to study the sun. It will be India’s
first satellite to do so.
mission is aimed at studying the Sun from a halo orbit around the Sun-Earth
Lagrangian point 1, henceforth the name Aditya-L1
Aditya L-1 mission will study the Sun’s corona -the outer layer.
major objectives of the mission are: a) Realization and launch of a satellite
in a Halo orbit around L1, b) Understanding solar upper atmospheric
(chromosphere and corona) dynamics, c) Study of chromospheric and coronal
heating and d) Observe the in-situ particle and plasma environment to provide
data for the study of particle dynamics from the Sun.
points are the positions in the orbits of two large celestial bodies, where the
smaller object or satellite will be affected by the combined gravitational pull
of the two large bodies (e.g. the Sun and the Earth).
are 5 such points out of which, only at L1, the gravitational attraction of one
of the larger bodies is cancelled by the other.
