India successfully launches Aditya mission to study the sun

ISRO Aditya L1 launch highlights: Launch successful as satellite separates from PSLV

Aditya L1 mission highlights: India's first solar mission, Aditya L1 launched today. After a four month journey, it will study solar activity and its effect on Earth, other planets and space weather.

The Aditya L1 mission will take an approach similar to the Chandrayaan-3 mission. It will first get into an Earth orbit and from there, it will go higher and faster until it eventually puts itself on a path to its final halo orbit around the first Lagrange point (L1) of the Earth and the Sun. The Lagrange point is a convenient vantage point for the probe because being around it would mean that it can remain in the same position without using a lot of fuel. This is also why the National Aeronautics and Space Administration (NASA) placed the James Webb Space Telescope at the second Lagrange point. (L2)

Off the back of a successful launch on the PSLV rocket, the Aditya L1 mission now has a 120-day mission ahead of it. In those four months, the spacecraft will first raise its orbit around Earth multiple times till it is in position to leave Earth's sphere of influence. After that exit manoeuvre, it will cruise towards the L1 Lagrange point till it reaches nearby and puts itself in a halo orbit around it.

Lagrange point - Wikipedia

en.wikipedia.org

Normally, the two massive bodies exert an unbalanced gravitational force at a point, altering the orbit of whatever is at that point. At the Lagrange points, the gravitational forces of the two large bodies and the centrifugal force balance each other. This can make Lagrange points an excellent location for satellites, as orbit corrections, and hence fuel requirements, needed to maintain the desired orbit are kept at a minimum.

Last year we launched our mission to the Sun.
How did we avoid heat overload?
We sent it at night.

The Indian Space Research Organisation (ISRO) on Saturday successfully placed Adiyta-L1, the first space-based Indian observatory to study the Sun, into its destination orbit Lagrange Point-1 - which is around 1.5 million kilometers from the Earth. According to ISRO officials, a satellite in a Halo orbit around the L1 point has the major advantage of continuously viewing the Sun without any occultations or eclipses.

ISRO successfully deploys magnetometer boom on board Aditya-L1 spacecraft

According to ISRO, the boom carries two state-of-the-art, high-accuracy fluxgate magnetometer sensors that measure the low intensity interplanetary magnetic field in space.

ISRO has successfully deployed the magnetometer boom on board the Aditya-L1 satellite to measure the low intensity interplanetary magnetic field in space.

The six metre-long magnetometer boom is deployed in the Halo orbit at the Lagrange point L-1, on January 11, the space agency said, noting that the boom had been in stowed condition for 132 days since the Aditya-L1 launch.

Total Solar Eclipse today: ISRO's Aditya-L1 to track Sun during ‘darkness’

Total solar eclipse on April 8: ISRO's Aditya-L1 will track the Sun on Monday as it gets completely cloaked by the Moon during the Total Solar Eclipse.

India's solar probe Aditya L1 will track the behaviour and rays of the Sun on Monday, April 8, during the total solar eclipse. During this time, the Sun will briefly get completely cloaked by the Moon, creating a moment of complete darkness in several countries.

Aditya L1, which is the Indian Space Research Organisation's (ISRO) maiden solar mission, is in a position to track the Sun during the total solar eclipse. This will help the ISRO further study the chromosphere and corona of the star.

Aditya L1 will use two of its six instruments to track the Sun during the solar eclipse. These two instruments are the Visible Emission Line Coronagraph (VELC) and the Solar Ultraviolet Imaging Telescope (SUIT).
