    Geomagnetic stroms:

    Geomagnetic storms are disturbances in Earth’s magnetosphere caused by solar activity, particularly solar flares and coronal mass ejections (CMEs) from the Sun. These storms occur when these solar events release charged particles (plasma) into space, known as the solar wind. When the solar wind interacts with Earth’s magnetic field, it can create fluctuations and disturbances during geomagnetic storms can enhance auroral activity at high latitudes, producing colorful displays known as the Northern and Southern Lights

    Impact of geomagnetic stroms on technology and infrastructure on Earth:

    1. Power Grids: Geomagnetically induced currents (GICs) can flow through power lines, transformers, and pipelines, potentially causing equipment damage and leading to power grid instability. This can result in widespread blackouts and require extensive repairs.

    2. Satellite Operations: Geomagnetic storms can disrupt satellite operations by causing increased atmospheric drag and radiation exposure. This can affect satellite orbits, communication systems, and navigation services such as GPS, leading to errors in positioning and timing.

    3. Communication Systems: High-frequency (HF) radio communications are particularly vulnerable to geomagnetic disturbances. Ionospheric changes during storms can disrupt radio signals, affecting aviation, maritime, and military communications.

    4. Navigation Systems: GPS systems rely on precise timing signals from satellites. Geomagnetic storms can introduce errors in these signals, impacting navigation accuracy for both civilian and military applications.

    5. Pipeline and Cable Infrastructure: GICs induced during geomagnetic storms can lead to corrosion in pipelines and underground cables, posing maintenance challenges and safety risks.

    The Growing Concerns over Space Debris

    • The ever-increasing amount of space debris in Earth’s orbit poses a significant threat to operational satellites and ongoing space missions.
    • Space debris includes defunct satellites, spent rocket stages, and fragments from past collisions and explosions, which can travel at speeds of up to 28,000 km/h.
    • This debris can damage or destroy active satellites and spacecraft, posing a grave risk to critical infrastructure and communication networks that rely on these assets.

    Recent Examples Highlighting the Risks of Space Debris

    • In 2021, a chunk of a Chinese rocket weighing several tons re-entered the Earth’s atmosphere in an uncontrolled manner, raising concerns about the potential impact of such large debris on populated areas.
    • In 2022, the International Space Station was forced to perform an evasive maneuver to avoid collision with a piece of space debris, underscoring the immediate threats faced by operational missions.
    • The Hubble Space Telescope has also had to adjust its orientation multiple times to avoid collisions with debris, highlighting the widespread nature of the problem.

    International Efforts to Mitigate the Risks of Space Debris

    • International organizations, such as the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS), have established guidelines and best practices for the mitigation of space debris.
    • Space agencies worldwide, including NASA, ESA, and JAXA, have implemented debris monitoring and tracking systems to better understand the extent of the problem and predict potential collision risks.
    • There are also ongoing efforts to develop active debris removal technologies, such as net-capturing, harpoon, and robotic arm systems, to physically remove large pieces of debris from orbit.
    • International cooperation is crucial in addressing this global challenge, as it requires coordinated efforts in data sharing, technology development, and policy harmonization.

    The Way Forward: Sustainable Space Exploration

    • Responsible space operations and debris mitigation must be a priority for all space-faring nations and private companies to ensure the long-term sustainability of space activities.
    • Measures such as post-mission disposal of satellites, design considerations to minimize debris generation, and active debris removal initiatives need to be further strengthened and implemented universally.
    • Ultimately, the protection of the space environment is essential for the continued success of future space missions and the uninterrupted operation of critical space-based infrastructure.

    By addressing the growing concerns over space debris through international cooperation and coordinated efforts, UPSC Mains aspirants can demonstrate their understanding of this pressing issue and its implications for the future of space exploration and utilization.

    Model Answer

    Introduction

    Chandrayaan-3, launched by ISRO in 2023, represents India’s third lunar mission. Unlike its predecessors, this mission includes a lander and a rover but no orbiter. The primary objective is to achieve a soft landing on the Moon’s surface, a goal not accomplished in earlier missions.

    Main Task of Chandrayaan-3

    Soft Landing

    The mission’s core task is to execute a successful soft landing on the lunar surface. Chandrayaan-1 was solely an orbiter, while Chandrayaan-2 attempted a soft landing but failed due to a last-minute glitch. The successful landing of Chandrayaan-3 enables extensive lunar research and sample collection.

    Lunar Research and Material Extraction

    The successful landing allows scientists to analyze the Moon’s surface in detail, addressing limitations from previous missions. For instance, while Chandrayaan-1 identified water molecules, it couldn’t analyze samples. Chandrayaan-3 aims to collect lunar soil samples, a task that Chandrayaan-2 was unable to carry out due to its failed landing attempt.

    Countries that Have Achieved Soft Landing

    1. USA: The Apollo 11 mission in 1969 achieved not just a soft landing but also human presence on the Moon (Source: NASA).
    2. Russia: Luna 9 marked the first successful soft landing in 1966, transmitting photographs back to Earth (Source: Soviet Space Program).
    3. China: Chang’e 3 achieved a soft landing in 2013, followed by Chang’e 4 landing on the far side of the Moon in 2019 (Source: China National Space Administration).

    Subsystems in Chandrayaan-3

    Vikram Lander

    The Vikram lander is equipped with several advanced subsystems, including:

    • Laser Inertial Referencing and Accelerometer Package (LIRAP)
    • Ka-Band Altimeter (KaRA)
    • Lander Hazard Detection & Avoidance Camera (LHDAC)

    These systems work together to ensure a controlled descent and landing.

    Pragyan Rover

    The Pragyan rover is designed for surface exploration, conducting experiments and relaying data back to Earth.

    Communication and Data Collection

    The Deep Space Network ensures communication between the spacecraft and ground control, critical for mission success.

    Role of the Virtual Launch Control Centre (VLCC)

    The VLCC at Vikram Sarabhai Space Centre employs advanced technology to support the mission’s launch:

    1. Real-time Telemetry: Monitors all spacecraft subsystems during launch, ensuring functionality.
    2. Coordination: Synchronizes efforts across multiple systems and departments for a smooth launch.
    3. Anomaly Detection: Identifies unexpected conditions during launch, providing data for quick decision-making.
    4. Resource Management: Enables experts to collaborate virtually, addressing complex challenges efficiently.
    5. Technological Advancements: Utilizes machine learning for real-time predictions and solutions, contributing significantly to the launch’s success.

    Conclusion

    The success of Chandrayaan-3 marks a significant milestone for India in space exploration, paving the way for future missions and enhancing India’s status in the global space community.
