Rishu04 mins

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. Watch this space for additional information on this fascinating mission!

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.

Today is the 23rd of August 2023, this is going to be Mark in the history of India, today we conquer the moon, after many attempts we are finally able to make a soft landing on the moon. ISRO came a long way, it started with a small rocket launch that was carried on the Bullock cart and cycle. But now we have our own launchers to launch the rockets and satellites in Space. When chandrayaan2 fails, every country said ” for India there is no possibility to make a soft landing on the moon with a very small budget” we didn’t get demotivated at that time, we work on our weak points, we figured it out why chandrayaan2 fails, then we start working on chandrayaan3. Today chandrayaan3 lander and rover reached the surface of the moon and became the fourth country to do so, and first country to land on the South pole of the moon. After this successful mission now, India can do other big space missions as well, today we answer all the questions of 2019. Now we can proudly say we did it, now world can copy us. India and ISRO proved if we saw some dream, we can make it true, nothing will come in our way, ISRO proved that for a successful mission budget is not important, hard work and patience is important. We timesnews24 congratulate India and ISRO for the successful mission of chandrayan3 Jai hind jai Bharat

It has been announced by the Indian Space Research Organisation (ISRO) that Chandrayaan-3, India’s third lunar mission, is in the process of approaching the Moon and is scheduled to perform a significant maneuver on Monday, expected to take place between 11:30 AM and 12:30 PM. The information was shared by ISRO, stating, “Chandrayaan-3’s orbit has now been brought even closer to the moon’s surface, having been reduced to 174 km x 1437 km following a maneuver carried out on August 9. The subsequent operation is planned for August 14, 2023, during the time frame of 11:30 and 12:30 Hrs. IST,” as communicated on X (formerly referred to as Twitter) on August 9. Upon the completion of the required maneuvers, a precise landing site near the “Moon’s south pole” will be designated. Following this, the propulsion module will be separated from the lander while in orbit, enabling the lander to descend from orbit and endeavor to make a gentle landing. In relation to the present status and the schedule for landing on the Moon, it is expected that Chandrayaan-3 will contact the Moon’s surface on August 23 after a journey spanning 40 days. On August 9, Chandrayaan-3 moved even closer to the Moon, as its orbital path was adjusted to 174 km x 1437 km through the maneuver. Significant events in the Chandrayaan-3 Mission Timeline: July 6: The launch date of Mission Chandrayaan-3 was officially announced by ISRO as July 14 from Sriharikota’s second launch pad. July 7: Successful completion of vehicle electrical tests. July 11: Conducted a 24-hour ‘Launch Rehearsal,’ simulating the entire launch process. July 14: Chandrayaan-3 was successfully launched into its intended orbit by the LVM3 M4 vehicle. Various orbit-raising maneuvers were carried out successfully, gradually adjusting the spacecraft’s orbit dimensions. August 1: Chandrayaan-3 achieved a significant milestone by entering the translunar orbit, with an orbit of 288 km x 369,328 km. August 5: The spacecraft successfully entered the lunar orbit with an orbit of 164 km x 18,074 km. August 6: The spacecraft’s orbit was further lowered to 170 km x 4,313 km around the Moon. August 9: Executed a maneuver, bringing Chandrayaan-3 even closer to the Moon, thereby lowering its orbit to 174 km x 1437 km.

Like Chandrayaan-2, Chandrayaan-3’s lander and rover have the names Vikram and Pragyan, respectively. If the lander is called Vikram, the rover that will emerge from it once it touches down on the moon’s surface is called Pragyan. The name of the mission has been repeated for Chandrayaan-3 because the previous mission’s attempt to operate on the moon’s surface failed. The Chandrayaan-3 mission’s primary goal is to thoroughly investigate the Moon’s southern pole and surface. Scientists claim that there is a substantial amount of water ice and a lot of sunshine in this area of the Moon.It is anticipated that research into this area will one day be useful for Mars expeditions. The fact that Chandrayaan-3 was the first spacecraft to land on the southern pole of the Moon is another notable feature of this mission. A lander Vikram and how it works The Vikram lander will start its activities following a gentle touchdown. It will give ISRO (Indian Space Research Organisation) its first photograph a short while after landing. As long as it is on the Moon’s surface, it will function. Activities of the rover:- After around three hours, the rover, called Pragyan, will leave the lander. Numerous moon-related research endeavors will be facilitated by the lander. After a successful soft landing, the lander Vikram will carry out activities on the Moon’s surface and return data and photographs to ISRO. Later, the lander’s internal rover, named Pragyan, will emerge and conduct moon-related scientific investigations. The Pragyan rover’s duties:- The solar-powered rover Pragyan will be sent onto the Moon’s surface by the lander Vikram. This six-wheeled rover will travel at a pace of one centimeter per second across a distance of around 500 meters. On the lunar surface, the rover will do chemical analysis and send the results back to the lander. The ISRO space station will thereafter get this information from the lander. On the Moon, the Pragyan rover will continue to operate for around 14 days, which is equal to one lunar day or 14 days on Earth.

Singapore’s High Commissioner to India, Simon Wong, congratulated the Indian Space Research Organization (ISRO) on the successful launch of the PSLV-C56 on Friday. He mentioned that the rocket orbited seven satellites built by the Defence Science and Technology Agency (DSTA), ST Engineering, Singapore’s universities, and private business. “PSLV-C56/DS-SAR Mission: The mission was completed successfully.” All seven satellites were precisely launched into their intended orbits by PSLV-C56 vehicles. This is the 58th PSLV flight overall and the 17th with the Core Alone configuration. To ensure a shorter orbital life, the top stage of the rocket was placed in lower orbit after injecting all of the satellites. According to ISRO, the PSLV-C56 was launched from the First Launch Pad (FLP) at the Satish Dhawan Space Centre (SDSC), Srihari Kota. According to a previous ISRO publication, all satellites would be put into a 535 km circular orbit with a 5 orbital inclination. The DS-SAR satellite was created through a collaboration between DSTA (representing the Singapore Government) and ST Engineering. It will be utilized to support the satellite imaging requirements of various entities within the Singapore government once it is installed and operational. Dr. Subba Rao Pavuluri stressed that ATL is completely dedicated to supporting the country’s space sector efforts and other important projects as part of India’s goal of ‘Atmanirbhar Bharat.’
