Aditya L1 Mission! Navigating the Complex Stages of Solar Exploration

Aditya L1

Aditya L1: On Saturday, the Polar Satellite Launch Vehicle (PSLV) rocket from the Satish Dhawan Space Centre SHAR in Sriharikota, Andhra Pradesh, launched Aditya L1, India’s first solar mission. The Aditya L1 mission is anticipated to take four months to complete its whole voyage from launch to landing, according to the Indian Space Research Organisation (ISRO).

Which stages in Aditya L1’s journey is crucial?

Syed Ahmed, a former ISRO NASA scientist who currently works at XDLINX labs in Hyderabad, claims that despite the PSLV’s strong track record of 37 straight successful launches, the Aditya L1 mission offers special difficulties. This complexity results from the four-step propulsion mechanism, which switches between solid and liquid phases and necessitates precise ignition and performance at every level. “Any misfire or failure to ignite would take it straight down into Bay of Bengal,” he told HT. Unlike Chandrayaan, where one used the Earth as a slingshot and was later captured by the Moon, we can’t do that here because it will orbit an empty point and won’t be pulled by anything there, according to Somak Raychaudhury, a renowned astrophysicist who is currently vice-chancellor at Ashoka University. “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 told HT. According to Syed, the mission’s last stage begins about 100 days into the trip and lasts for about 1.5 million kilometres, or almost four times the distance between Earth and the Moon. The Liquid Apogee Motor (LAM) needs to fire precisely at this point in order to place the spacecraft into its intended halo orbit around the Lagrangian point.
