After lift-off, Aditya L1’s four-month-long voyage to the Lagrange level

According to the Indian Space Research Organisation (ISRO), your entire journey from the launch to reaching L1 is anticipated to take roughly 4 months for the Aditya L1 mission. Here is a breakdown of the journey to the Sun-Earth system’s L1 level.

Launch: The Aditya L1 mission will probably be launched by ISRO’s PSLV XL rocket from Satish Dhawan Space Centre SHAR (SDSC-SHAR), Sriharikota.

Initial Orbit: The spacecraft will probably be initially positioned in a Low Earth Orbit.

Elliptical Orbit: The orbit will then be adjusted to turn into extra elliptical.

Exit from Earth’s Gravitational Sphere of Influence (SOI): The spacecraft will probably be propelled in direction of the L1 level utilizing onboard propulsion. As the spacecraft strikes in direction of the Lagrange level, it can exit Earth’s gravitational Sphere of Influence.

Cruise Phase: After leaving Earth’s SOI, the cruise section of the mission will begin.

Halo Orbit: Subsequently, the spacecraft will probably be injected into a big halo orbit across the Lagrange level (L1).

Which are vital phases of Aditya L1 journey?

According to Syed Ahmed, a former ISRO NASA scientist now working at XDLINX labs in Hyderabad, the Aditya L1 mission presents distinctive challenges regardless of the PSLV’s spectacular observe document of 37 consecutive profitable launches. This complexity arises from the four-stage propulsion course of, transitioning from strong to liquid phases, with every stage requiring flawless ignition and efficiency.

“Any misfire or failure to ignite would take it straight down into Bay of Bengal,” he advised HT.

Somak Raychaudhury, an eminent astrophysicist at present serving as vice-chancellor at Ashoka University, explains that not like Chandrayaan, the place one used the Earth as a slingshot after which captured by the Moon, right here, we won’t do this as a result of it’s going to orbit an empty level and thus it isn’t going to be pulled by one thing there.

“So the critical stages will be when it will leave the Earth’s orbit and when it will go around, reach the Lagrangian point and be put into the L1 point’s orbit,” he advised HT.

Syed explains that the final word section of the mission happens roughly 100 days into the journey, protecting a distance of roughly 1.5 million kilometres—4 instances the space between Earth and the Moon. During this stage, the Liquid Apogee Motor (LAM) should hearth exactly to place the spacecraft into its designated halo orbit across the Lagrangian level.
