India’s Space Supremacy on Ascent

Chandrayaan-3, ISRO’s premier lunar exploration is a milestone in its path to achieving greater excellence, cost competitiveness and emerge as space power Rahul Pawa Human space exploration has predominantly been shaped by superpowers of the Cold War era, with US space agency, NASA and its Russian counterpart, Roscosmos leading the way. This is a thing of the past. In recent decades, the biggest surprising candidate in contention is the Indian Space Research Organisation (ISRO). Though it started late and faces financial limitations as well as technological constraints, ISRO has demonstrated remarkable resilience and determination, carving out a unique path as a top-tier global space agency. Established in 1969, almost two decades after NASA, ISRO embarked on its journey amidst a space race that was already in full swing. Tasked with the formidable mission of propelling India into the age of space technology and catching up with technologically advanced nations, ISRO’s journey has been far from smooth. In the aftermath of India’s nuclear tests in 1974 and 1998, the nation faced broad international sanctions. This development dealt a significant blow to India’s space aspirations when Russia, succumbing to pressure from the Western world, cited the Missile Technology Control Regime (MTCR) and withdrew from an agreement to transfer crucial cryogenic engine technology to India. The cryogenic engine technology was indispensable for the development of heavy-lift launch vehicles. Such a setback could have easily derailed India’s ambitions. Instead, it ignited ISRO’s determination, fuelling its drive towards self-reliance and innovation. Over next two decades, ISRO focused its efforts on developing its own cryogenic engine technology. Despite numerous challenges, India’s space agency remained unwavering and in January 2014, it successfully launched the GSLV-D5 launch vehicle, powered by an indigenously developed cryogenic engine. This achievement serves as an exemplary showcase of perseverance and resilience in the face of adversity, a testament to ISRO’s unwavering commitment to its mission and the Indian Republic. Yet, this is just one chapter in the compelling saga of ISRO, where hurdles are transformed into springboards for success. It is a testament to ISRO’s prowess in transforming adversity into opportunity, illuminating India’s flourishing technological capabilities. As ISRO navigated its journey, it pioneered a new paradigm in space exploration, combining cost-effectiveness with ambition, establishing itself as a trailblazer in affordable space technology. The Mars Orbiter Mission, known as Mangalyaan, epitomises this innovative spirit. Accomplished at a fraction of the cost of similar missions by other agencies, Mangalyaan was not just a frugal exploration but a powerful demonstration of ISRO’s formidable capabilities to the world. A vivid illustration of ISRO’s economical yet ambitious spirit is its mastery of multi-launch capabilities, allowing multiple satellites to be taken into orbit with a single rocket. ISRO showcased this brilliantly in February 2017 when it successfully launched a record-breaking 104 satellites aboard a single PSLV-C37 rocket. This launch included not only India’s own earth observation satellite but also miniature satellites from several international players, underscoring ISRO’s leading role in the global commercial space industry. Furthermore, ISRO’s ability to maintain budgetary controls without compromising on scientific endeavours sets it apart from many international counterparts. Whether it is launching the world’s lightest satellite or sending a mission to Mars at a cost lower than a Hollywood blockbuster, ISRO’s exemplary record reflects that cost-effectiveness and ambitious exploration can indeed go hand in hand.  Chandrayaan-3, the latest iteration of ISRO’s flagship lunar exploration mission, is poised to embark on its momentous journey, aiming to achieve a soft landing in the Moon’s South Polar region on August 23, 2023 at 5:47 pm. This extraordinary endeavour, born out of years of rigorous scientific inquiry, stands as evidence of India’s expanding influence as a formidable force in space exploration. Chandrayaan-3 aims to succeed where its predecessor fell short, achieving a precise and controlled landing on the lunar surface. The proposition for an Indian moon mission was formally announced by former Indian Prime Minister Atal Bihari Vajpayee during his 2003 Independence Day address, and in 2008, Chandrayaan-1 was launched, marking a significant milestone in India’s cosmic journey. Comprising a lunar orbiter and impactor, Chandrayaan-1 not only fulfilled its scientific ambitions but also propelled India into an elite group of lunar explorers. Even before Chandrayaan-1 landed, ISRO and Roscosmos planned its sequel, Chandrayaan-2, with the goal of a moon landing and rover exploration. Due to delays from Roscosmos, ISRO independently developed a lander, pushing the launch to 2019. Technical setbacks and rescheduling notwithstanding, Chandrayaan-2 finally took off on July 22, 2019. Tragically, a software glitch on September 6, 2019, caused the Chandrayaan-2 lander to malfunction, resulting in the loss of communication with ISRO and loss of both the lander and the rover. This incident led to the development of Chandrayaan-3, the next phase of the mission, with the ambitious aim of achieving a successful soft lunar landing. With the clock ticking down, ISRO is diligently overseeing the timeline for the lunar touchdown, taking into account elements such as lunar sunrise. In case circumstances demanded, the landing can be pushed to September from the scheduled August 23 this year. Every step forward brings India’s Chandrayaan-3 closer to a ground breaking achievement on the moon. Successfully achieving this would place India in an elite group of nations; to date, only the US, Russia, and China have accomplished this feat. Odyssey of ISRO embodies the indomitable spirit of human endeavour—an unwavering resolve, tireless perseverance, and self-reliance that magnify India’s ascent as an increasingly formidable space superpower, bolstering its commanding presence within the global space community. Having begun as a latecomer, ISRO has transcended the confines of limitations and boldly challenged established order, thereby demonstrating that constraints are merely catalysts for boundless opportunities. ISRO’s unwavering dedication to perpetual learning, adaptability, and evolution has empowered it to overcome formidable obstacles and lay a robust groundwork for future triumphs. Through a multitude of accomplishments, it has forged an upward trajectory for India, shaping it into a rising space superpower of exceptional versatility.

Chandrayaan-3: Another feather in India’s space odyssey

Prachi Mishra Chandrayaan-3, India’s lunar mission, successfully launched on July 14, 2023 in the afternoon from the Satish Dhawan Space Center in Sriharikota. The launch was carried out using the powerful Launch Vehicle Mark-III (LVM3) rocket. The Indian Space Research Organisation (ISRO) is responsible for managing the mission and overseeing the launch. With its origins dating back to 1962, ISRO has a rich history in space exploration, and it officially came into existence in 1969. Since then, ISRO has played a significant role in India’s space endeavors. In June 2023, just prior to the planned launch of Chandrayaan-3, India joined the Artemis Accords led by NASA. These accords focus on fostering peaceful exploration of the Moon by humans and robots. While the primary advantages of the accords pertain to human spaceflight, the White House stated that the data obtained from Chandrayaan-3 could also prove valuable for future Artemis missions involving human landings. According to the Times of India, the estimated cost of Chandrayaan-3 is approximately $77 million USD. The official website states that Chandrayaan-3 has three main objectives: to achieve a safe landing on the lunar surface, to demonstrate rover operations, and to conduct scientific experiments on-site. As per the scientists involved in building and launching of the Moon mission the anticipated landing is expected to occur around August 23 or August 24. The mission involves a propulsion module that will transport the lander and rover to the Moon’s south pole. Once in lunar orbit, the module will adjust its trajectory to form a circular path roughly 60 miles (100 km) above the lunar surface. Subsequently, the lander will separate from the module and endeavor to make a soft landing on the Moon. During its 14 Earth-day surface mission (equivalent to a single lunar day), the lander and rover will conduct scientific investigations. Meanwhile, the propulsion module will observe Earth as part of its own scientific experiment. ISRO has incorporated advanced technologies into the spacecraft package, which includes the rover, lander, and propulsion module. These technologies encompass hazard detection and avoidance capabilities for the rover, a landing leg mechanism designed for a gentle touchdown, as well as altimeters and velocity instruments to estimate altitude and speed above the lunar surface. ISRO has conducted numerous technology tests to simulate lunar conditions, placing instruments in cold temperatures resembling the Moon’s environment and performing lander leg tests on simulated surfaces under various landing conditions. The agency has emphasized the importance of these tests in preparing for the mission. The scientific payload of the Chandrayaan-3 mission is divided among the lander, rover, and propulsion module. The lander is generally box-shaped and equipped with four landing legs and four landing thrusters. Its total mass of approximately 3,900 pounds (1,752 kilograms) includes 57 pounds (26 kilograms) allocated for the rover. The lander incorporates several instruments and experiments, including: As for the rover, it is a rectangular chassis mounted on a six-wheel rocker-bogie wheel drive assembly. The rover communicates with Earth through the lander. Its instrument suite includes: The propulsion module is a box-like structure, features a large solar panel mounted on one side and a cylindrical structure on top serving as a mounting platform for the lander. With a mass exceeding 2.2 tons (2 tonnes), the propulsion module contributes significantly to the mission’s overall weight. The module’s primary experiment is the Spectro-polarimetry of Habitable Planet Earth (SHAPE) investigation, which supports exoplanet searches. This experiment involves collecting data on the polarization of light reflected by Earth, aiding in the search for other planets with similar characteristics, as reported by Nature. Today, the Indian Space Research Organisation (ISRO) is embarking on its second endeavor to achieve a successful moon landing with the launch of Chandrayaan-3. With Chandrayaan-3, India has once again proven to the world that with indigenous capabilities and domestic talent, it can very well drive its space odyssey.
