3. ABOUT ADITYA-L1
⢠Aditya L1 mission is second astronomy mission of ISRO.
⢠Aditya L1 will observe the photosphere, chromosphere and corona of the sun.
⢠Aditya L1 contains seven payloads in order to get multi-dimensional
observation of the sun. In addition to this, Aditya also has soft and hard x-Ray,
UV, broadband filter, magnetometer. Magnetometer observes the magnetic
field of any object.
4. ORIGIN OF THE MISSION
⢠In 2008, ISRO planned to launch a spacecraft to explore the surface of the sun.
⢠It was a 400 KG satellite with one payload âthe visible emission line
chronographâ(VELC) to launch in 800 kilometre Low Earth orbit.
⢠Stepping ahead, ISRO decided to launch a spacecraft to study the sun.
⢠ISRO further gives the name âAditya 1â. Rather, Aditya-1 designed to study only
the outer surface of the sun.
5. PAYLOADS USED IN ADITYA-L1
⢠This mission has highly advanced payloads, or say, instruments to prove it a
milestone. Following are those payloads:
⢠Visible Emission Line Coronagraph (VELC)
⢠Solar Ultraviolet Imaging Telescope (SUIT)
⢠Aditya Solar wind Particle Experiment (ASPEX)
⢠Plasma Analyser Package for Aditya (PAPA)
⢠Solar Low Energy X-ray Spectrometer (SoLEXS)
⢠High Energy L1 Orbiting X-ray Spectrometer (HEL1OS)
⢠Magnetometer
6. IMPORTANCE OF THE MISSION
⢠NASA on August 12,2018 launched solar probe named Parker Solar
Probe to study the Solar winds acceleration and the solar corona.
⢠Solar flares and other disturbances of the sun emits energetic atomic
particles and X-rays.
⢠These particles and X-rays affect the radio waves travelling through
Earth Ionosphere. It interferes and often causes blackouts on the
earth.
⢠Sometimes, solar phenomenon disturbs the Earthâs magnetic field
inducing High Voltage fluctuation.
⢠Also, variation in Solar weather can change the satellite Orbit or
shorten their lives and even damage on board electronics.
⢠Therefore, Observation of the Sun becomes necessary in order to track
Earth directed Storms and the impacts.
7. FUTURE GOALS
⢠Lunar Polar Exploration Mission:Indian Space Research Organisation and
Japan Aerospace exploration energy will collaborate to launch this mission for
exploring the research Pole region of the Moon.
⢠RISAT-1A: Rada Imaging Satellite 1A series of research satellites.
⢠Gaganyan: Gaganyan is an âIndian skewed spacecraftâ.
