Countdown on! When will Aditya-L1 mission reach its destination to watch the Sun? Check ISRO plan

So, when will Aditya-L1 mission reach its destination? India's pioneering solar mission is set to arrive at its destination by the first week of January 2024. 

The Aditya-L1 spacecraft, crafted by the Indian Space Research Organisation (ISRO), is on a mission to scrutinise the Sun's corona and unravel the mysteries of solar storms.

The Challenge Ahead: Reaching the parking spot, Lagrange Point L1, poses a formidable challenge due to the immense distance and gravitational forces. Delving into the factors influencing Aditya-L1's travel time will shed light on this cosmic journey.

Factor 1 - Launch Trajectory: The launch trajectory of Aditya-L1 is pivotal in determining its travel time. Utilising the Geosynchronous Satellite Launch Vehicle (GSLV) from India's Satish Dhawan Space Centre, the trajectory will leverage gravitational assists to reduce travel time.

Factor 2 - Distance to the Sun: Aditya-L1 must traverse the vast expanse between Earth and the Sun, averaging a staggering 93 million miles (150 million kilometres). The elliptical orbit of Earth introduces variability in this distance.

Factor 3 - Speed of the Spacecraft: Aditya-L1's velocity is a critical factor in determining travel time. Propelled by its onboard propulsion system, the spacecraft gradually increases speed, influenced by mission requirements and chosen trajectory.

Factor 4 - Gravity Assists: Harnessing gravity assists from celestial bodies like the Moon or planets accelerates Aditya-L1, reducing travel time. Precisely planned flybys strategically utilise gravitational pulls to propel the spacecraft towards its destination.

Estimated Travel Time: While exact travel time remains elusive without mission specifics, drawing parallels with NASA's Parker Solar Probe offers insights. The Parker Solar Probe, a comparable solar mission, took roughly 6 months to reach its first Sun close approach.

Considering technological strides and Aditya-L1's mission objectives, a comparable or slightly extended travel time is a reasonable expectation.

Aditya-L1 mission’s journey to the Sun encompasses a blend of precision, technological prowess, and celestial assists. The unveiling of solar mysteries awaits as the spacecraft approaches its cosmic destination.
