ADITYA-L1 MISSION - SCIENCE AND TECHNOLOGY
News: India’s
first mission to study the Sun will be launched by June-July: ISRO chairman
What's in the news?
● The
Indian Space Research Organization (ISRO) is planning to launch the Aditya-L1
mission by June or July this year.
● Aditya-L1 is the first
Indian space mission to observe the Sun and the solar corona.
Key takeaways:
● The
Aditya-L1 mission will be launched by ISRO to the L1 orbit (which is the first Lagrangian point of the Sun-Earth system).
L1 orbit allows Aditya-L1 to look at the Sun continuously.
● In
total Aditya-L1 has seven payloads, of which the primary payload is the Visible
Emission Line Coronagraph (VELC), designed and fabricated by the Indian Institute of Astrophysics, Bengaluru.
Aditya-L1 Mission:
● The
Aditya- L1 is a 400 kg-class satellite, which will be launched from the Polar Satellite Launch Vehicle (PSLV-XL).
● The
Aditya- L1 will be positioned near the L-1 (Lagrange Point 1) located between
the Sun and the Earth.
● It
is a joint venture between ISRO and physicists from other institutes of India.
Objectives of Mission:
● Study
the dynamic nature of the sun's outermost layers, the corona and the
chromosphere, and collect data about
Coronal Mass Ejections (CME).
● Study
on origin of solar storms and their path through the interplanetary space from
the Sun to the Earth.
● The
studies will also focus on collection of information for space weather prediction.
Features:
● It
will study the sun’s outermost layers:
○ Photosphere
(soft and hard X-ray)
○ Chromosphere
(UV) and
○ Corona
(Visible and NIR)
● It
will collect data about coronal mass ejection, which will also yield
information for space weather prediction.
