ISRO’s Aditya-L1 Mission: Heading Towards the Sun

In the late hours of the night, while most of us are tucked in our beds, the Indian Space Research Organisation (ISRO) is gearing up for an exciting event – the fourth earth-bound manoeuvre for its Aditya-L1 mission. Scheduled for 2 am IST, this critical step is part of a meticulously planned series of orbit-raising manoeuvres. These manoeuvres are essential to prepare Aditya-L1, India’s first solar observatory, for its ambitious journey to the Sun-Earth Lagrange Point 1 (L1). 1. When did the mission be initiated and what is next going to happen? Aditya-L1 embarked on its mission on September 2, and since then, it has been making steady progress. The spacecraft has already successfully executed three earth-bound manoeuvres, with the most recent one occurring on September 10. After the third manoeuvre, Aditya-L1 achieved a new orbit with dimensions of 296 km x 71767 km. However, the journey is far from over, as the fourth manoeuvre, scheduled for September 15, is poised to further elevate the spacecraft’s orbit, bringing it one step closer to its ultimate destination. 2. What is the significant of L1 point? The L1 point, initially discovered by the renowned mathematician Joseph Louis Lagrange, holds a special place in the realm of solar observations. A satellite positioned in a halo orbit around the L1 point enjoys an uninterrupted view of the Sun, free from any occultations or eclipses. This unique vantage point enables real-time observations of solar activities and their impact on space weather, making it a prime location for a solar observatory like Aditya-L1. 3. What are the payloads carried by Aditya L1? Aditya-L1 is not just another space mission; it’s a powerhouse of scientific instruments. The spacecraft carries seven payloads designed to study various layers of the Sun. Four of these payloads are dedicated to directly observing the Sun, providing us with valuable insights into its behaviour. Meanwhile, the remaining three payloads are focused on conducting in-situ studies of particles and fields at the L1 point, deepening our understanding of space weather and its effects. Conclusions: – As ISRO continues to push the boundaries of space exploration, the Aditya-L1 mission stands as a testament to India’s commitment to advancing our knowledge of the Sun and its influence on our planet. So, while we sleep soundly, Aditya-L1 ventures into the depths of space, bringing us closer to unravelling the mysteries of our closest star.

Sulphur found on the moon by the rover Pragian 2023

Following the release of data from a temperature-profiling instrument aimed at studying the lunar surface, the Indian Space Research Organisation (ISRO) has announced a significant breakthrough. Another instrument aboard Chandrayaan-3, the lunar mission, has identified the presence of various elements on the Moon’s surface. Of note is the discovery of Sulphur, a crucial finding as direct evidence of its existence had previously been elusive. The accomplishment comes courtesy of the Laser-Induced Breakdown Spectroscopy (LIBS) instrument housed within the Chandrayaan-3 Rover. Through this tool, a pioneering instance of in-situ measurements has been achieved, detailing the elemental composition of the lunar surface in the vicinity of the South Pole. ISRO expressed its satisfaction, stating, “These in-situ measurements confirm the presence of Sulphur (S) in the region unambiguously, something that was not feasible by the instruments onboard the orbiters.” Initial analysis has further unveiled the presence of Aluminium (Al), Calcium (Ca), Iron (Fe), Chromium (Cr), and Titanium (Ti) on the Moon’s surface. Additionally, subsequent measurements have exposed the existence of Manganese (Mn), Silicon (Si), and Oxygen (O). An ongoing comprehensive investigation aims to ascertain the presence of Hydrogen. The Chandrayaan-3 mission centres on acquiring insights into the presence and prevalence of diverse elements on the lunar surface. This objective is pursued through the concerted efforts of multiple instruments. The LIBS tool, crafted by ISRO’s Laboratory for Electro-Optics Systems (LEOS), employs a high-energy pulsar to generate plasma from rocks or soil. In this plasma state, elements emit distinct wavelengths of radiation, allowing for their precise identification. With this achievement, ISRO’s Chandrayaan-3 mission takes a notable stride towards enhancing our understanding of the Moon’s composition and characteristics, shedding light on its geological history and evolution.
