Aditya L1 Launch LIVE Updates: Aditya-L1 will neither land on the Sun nor approach the Sun any closer. It will stay approximately 1.5 million km away from Earth, directed towards the Sun, which is about 1% of the Earth-Sun distance.
Aditya L1 Launch LIVE Updates: Aditya-L1 will blast off from Sriharikota at 11:50 am. Aditya L1 will take an approach similar to Chandrayaan-3 to reach its designated spot. Aditya L1 will stay in earth-bound orbits for 16 days as it undergoes five manoeuvres to gain speed needed for the L1 trip.

Aditya L1 Launch LIVE Updates: Two important things to remember
– Aditya L1 Mission will not “land” on the Sun. It will be placed in the orbit of the Sun-Earth system.
– It will be placed in a halo orbit around Lagrangian Point 1 (L1) – 1.5 million km from the Earth in the direction of the Sun. It will revolve around the Sun and observe solar activities and their effect on space weather real-time.
Aditya L1 Launch LIVE Updates: The probe that ‘touched’ the Sun
NASA’s Parker Probe touched the Sun for the first time in history in 2021. The probe navigated Sun’s upper atmosphere, known as the corona, and sampled particles and magnetic fields within.
Aditya L1 Launch LIVE Updates: Elon Musk will be watching
SpaceX’s Starlink satellites were hit by a geomagnetic storm triggered by a solar flare. It is these flare-ups that Aditya’s VELC is set to study
Aditya L1 Launch LIVE Updates: What do we need to know about the Sun?
India expects to get past, present and future info on the after analysing Aditya L1 data. This will help it understand possible climatic changes on Earth in the decades and centuries ahead.
Aditya L1 Launch LIVE Updates: The key engine that Aditya will rely on
‘LAM’ a small engine has a will critical role to play in the Aditya L1 mission. The successful operation of LAM, short for Liquid Apogee Motor, is vital to place the craft in a halo orbit at L1.
Aditya L1 Launch LIVE Updates: Spacecraft to stay in Earth orbits for 16 days
Aditya L1 will stay in earth-bound orbits for 16 days as it undergoes five manoeuvres to gain speed needed for this trip. It will stay approximately 1.5 million km away from Earth.
Aditya L1 Launch LIVE Updates: ASPEX, the only payload to be on during transit
The only payload to be on during transit will be the Aditya Solar wind Particle Experiment (ASPEX). This will do in situ measurements of solar particles and ions
Aditya L1 Launch LIVE Updates: L1 is not an object
L1 is not an object, it is a location in space, which moves with Earth around the Sun
