Explain ADITYA-L1 By AKSHAY SHELKE
Aditya-L1: The launch is scheduled
on September 2, 2023 at 11:50 am
Aditya L1 shall be the first space based Indian mission to study
the Sun. The spacecraft shall be placed in a halo orbit around the Lagrange
point 1 (L1) of the Sun-Earth system, which is about 1.5 million km from the
Earth. A satellite placed in the halo orbit around the L1 point has the major
advantage of continuously viewing the Sun without any occultation/eclipses.
This will provide a greater advantage of observing the solar activities and its
effect on space weather in real time. The spacecraft carries seven payloads to
observe the photosphere, chromosphere and the outermost layers of the Sun (the
corona) using electromagnetic and particle and magnetic field detectors. Using
the special vantage point L1, four payloads directly view the Sun and the
remaining three payloads carry out in-situ studies of particles and fields at
the Lagrange point L1, thus providing important scientific studies of the
propagatory effect of solar dynamics in the interplanetary medium
The suits of Aditya L1 payloads are expected to provide most
crucial informations to understand the problem of coronal heating, coronal mass
ejection, pre-flare and flare activities and their characteristics, dynamics of
space weather, propagation of particle and fields etc.
Science
Objectives:
The major science
objectives of Aditya-L1 mission are:
- Study of Solar upper atmospheric
(chromosphere and corona) dynamics.
- Study of chromospheric and coronal
heating, physics of the partially ionized plasma, initiation of the
coronal mass ejections, and flares
- Observe the in-situ particle and plasma
environment providing data for the study of particle dynamics from the
Sun.
- Physics of solar corona and its heating
mechanism.
- Diagnostics of the coronal and coronal
loops plasma: Temperature, velocity and density.
- Development, dynamics and origin of CMEs.
- Identify the sequence of processes that
occur at multiple layers (chromosphere, base and extended corona) which
eventually leads to solar eruptive events.
- Magnetic field topology and magnetic field
measurements in the solar corona.
- Drivers for space weather (origin,
composition and dynamics of solar wind.
The instruments of Aditya-L1 are tuned to observe the solar atmosphere mainly the chromosphere and corona. In-situ instruments will observe the local environment at L1. There are total seven payloads on-board with four of them carrying out remote sensing of the Sun and three of them carrying in-situ observation.
Payloads along with their major capability of scientific
investigation.
