Aditya L1 reaches pivotal phase: ISRO begins countdown to halo orbit insertion | Oneindia News
India's Aditya L1 spacecraft is gearing up for a groundbreaking mission as it approaches the final stages of its journey to Lagrange Point 1. The Lagrange Point 1 is a gravitational sweet spot between Earth and the Sun. Now, in the coming days, Aditya L1 is poised to execute a complex insertion into the halo orbit around Lagrange Point 1. This critical phase demands precision in navigation and control, requiring meticulous planning and execution by ISRO's team.

00:00 India's Aditya L1 spacecraft is gearing up for a groundbreaking mission as it approaches
00:08 the final stages of its journey to the Lagrange Point 1.
00:13 The Lagrange Point 1 is a gravitational sweet spot between the Sun and the Earth.
00:18 Launched by the Indian Space Research Organisation or ISRO on September 2nd from Sriharikota,
00:23 Aditya L1 has covered an impressive 15 lakh km in the vast expanse of space.
00:30 Its mission is to culminate on January 6th of 2024.
00:34 Now in the coming days, Aditya L1 is poised to execute a complex insertion into the halo
00:39 orbit around Lagrange Point 1.
00:42 This critical phase demands precision in navigation and control requiring meticulous planning
00:48 and execution by ISRO's team.
00:51 The significance of Lagrange Point 1 cannot be overstated.
00:54 Positioned to offer an uninterrupted view of the Sun, Aditya L1 aims to study the solar
00:59 atmosphere, magnetic storms and their impact on Earth's environment.
01:07 The spacecraft's instruments include the Visible Emission Line Coronagraph or VELC and the
01:13 Solar Ultraviolet Imaging Telescope or SOOT.
01:17 They will measure crucial events such as coronal mass ejections or CMEs and interplanetary
01:22 magnetic fields.
01:24 However, entering the halo orbit is no small feat.
01:28 The spacecraft underwent four Earth-bound orbital manoeuvres before being injected into
01:32 a transfer orbit towards L1.
01:35 To ensure success, ISRO's team must constantly monitor and adjust Aditya L1's position and
01:41 speed.
01:42 As per ISRO, it is using onboard thrusters to counteract any deviations from the planned
01:47 path.
01:48 But that's not all.
01:49 The spacecraft's instruments must be shielded from the intense radiation and particles emitted
01:54 by the Sun.
01:55 Aditya L1's stability at L1, which is an inherently unstable Lagrange Point, poses additional challenges.
02:03 Station-keeping manoeuvres with adjustments ranging from 0.2 to 4 meters per second per
02:08 year will be essential to counteract gravitational influences and solar radiation pressure.
02:14 As Aditya L1 approaches its destination, the ISRO mission is on high alert.
02:19 It is ready to navigate the complexities of space travel.
02:22 The success of this insertion is not only crucial for India's space capabilities, but
02:27 promises to unlock new insights into the mysteries of our Sun and its influence on space weather.
02:34 This mission marks a significant step forward in India's space exploration endeavours,
02:38 demonstrating the nation's prowess in space technology and contributing valuable data
02:43 to the global scientific community.
02:45 Stay tuned as we follow Aditya L1's journey to Lagrange Point 1 and the exciting discoveries
02:50 that lie ahead.
02:51 "Aditya L1 will have an L1 point insertion in January 6.
