Aditya L1 will take four months to get to its planned parking spot at Lagrange point 1 (L1), 1.5 million kilometers from Earth, where the Sun’s and Earth’s gravitational pulls are equal to the centripetal force required for the spacecraft to move with them.
The probe’s exceptionally stable halo orbit, which allows it to study the Sun continually without being hindered by any Sun occultation by other celestial bodies, will start at L1. Seven payloads are on board the probe, four of which are for viewing the Sun directly and the remaining three for studying particles and fields at L1.

Whether they involve communication satellites or remote sensing satellites, ISRO’s space missions are all focused on helping people in some way. These took on global significance when ISRO partnered with other spacefaring countries on interplanetary missions like ISRO’s Moon and Mars probes, which also carried payloads from other countries. Aditya L1’s seven payloads were created locally to help researchers better understand solar phenomena and how they affect Earth.
The Earth’s magnetic field is not always constant, and when it weakens, the CMES produce geomagnetic storms that cause spikes in power lines and cables over great distances, disrupting electrical and communications infrastructure. As the CMEs interact with Earth’s magnetic field, radiation storms whirl about the planet and crimson auroras shimmer in the night sky. Because the ionized sun particles are absorbed or reflected by the Earth’s atmosphere, the magnetic storm itself does not endanger life on Earth. However, this does not lessen the sunburst’s annoyance value in any way because it interferes with high-tech ground and space systems by disrupting the ionosphere, a layer of the atmosphere that is electrically charged and utilized to reflect radio waves.
Thus, even while computers and other electronic devices that don’t rely on wireless transmissions, such various electronic devices, are unaffected, mobile phones that do rely on radio transmissions could malfunction, which would mean losing priceless data from circling satellites. A number of solar exploration missions have been launched as a result of the increase in global interest in the Sun over the past 20 years. With many probes, NASA led the field, and was followed by Japan, Europe, Russia, and China. Modern instruments on the ground and in space were used on these missions to research the magnetohydrodynamics and nuclear and plasma physics of the Sun.

The NASA Parker Solar Probe, which was launched in August 2018 and completed its most dramatic mission in December 2021, studied the structure and magnetic fields of the Sun’s upper atmosphere and corona, where temperatures can reach a million degrees Celsius. Aditya-L1 will soon be a member of this exclusive group of Sun-watching robots, whose studies will advance our knowledge of the Sun. In turn, this will aid in the study of other stars (especially those with planets) and the forecasting of space weather, which is crucial for space exploration.
