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.
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.
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.
The Vikram lander is equipped with several advanced subsystems, including:
These systems work together to ensure a controlled descent and landing.
The Pragyan rover is designed for surface exploration, conducting experiments and relaying data back to Earth.
The Deep Space Network ensures communication between the spacecraft and ground control, critical for mission success.
The VLCC at Vikram Sarabhai Space Centre employs advanced technology to support the mission’s launch:
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.

Launched on December 25, 2021, the James Webb Space Telescope (JWST) represents a groundbreaking advancement in astronomical observation, far surpassing its predecessor, the Hubble Space Telescope. With its innovative design, JWST promises to unlock the secrets of the universe and enhance our understanding of cosmic phenomena.
Unlike Hubble, which required regular servicing missions, JWST is designed to operate for at least 10 years without maintenance, thanks to advanced technology and efficient resource management.
JWST features a larger mirror (6.5 meters in diameter compared to Hubble’s 2.4 meters) and state-of-the-art instruments, allowing it to achieve far superior resolution for observing distant celestial bodies.
JWST’s specialized instruments are tailored for sophisticated exoplanet detection, enabling the study of planets in habitable zones, a significant leap from Hubble’s capabilities.
JWST can peer further back in time than Hubble, capturing images of the universe’s first galaxies, thus probing the era of reionization.
With its advanced instruments, JWST offers deeper insights into our solar system, analyzing celestial bodies across multiple spectra.
JWST will provide unprecedented insights into our cosmic origins, helping us understand the potential for life beyond Earth. It will also inspire future generations to explore the cosmos, acting as a catalyst for scientific curiosity and discovery.
In summary, the James Webb Space Telescope is not just an advanced observational tool; it serves as a cosmic time machine and a source of inspiration for humanity’s quest for knowledge. Its findings will revolutionize our understanding of the universe and our place within it.

Asteroids are rocky, airless remnants from the early formation of our solar system, dating back approximately 4.6 billion years. They primarily orbit the Sun in the asteroid belt between Mars and Jupiter and vary widely in size and composition, containing rock, metals, and other elements. Asteroids are categorized into types such as C-type (carbonaceous), S-type (silicaceous), and M-type (metal-rich).
The threat posed by asteroids is significant, particularly due to historical events. For instance, a massive asteroid impact is believed to have caused the extinction of the dinosaurs around 66 million years ago, with the Chicxulub crater in Mexico marking the impact site. Such large asteroids, typically over 1 km in diameter, could lead to global catastrophes, including severe climate disruption and ecosystem collapse. Although the probability of a significant impact is low, the potential consequences warrant concern. NASA’s Planetary Defense Coordination Office emphasizes the severe global effects that could result from a large impact.
To mitigate the risks associated with asteroids, several strategies have been developed:
While the likelihood of a life-extinguishing asteroid impact is low, the severe consequences of such an event necessitate ongoing vigilance and preparedness through continuous monitoring, international collaboration, and technological advancements.

Model Answer
Introduction
India has achieved remarkable success in unmanned space missions, exemplified by the Mars Orbiter Mission (MOM) and Chandrayaan. However, the country has yet to embark on a manned space mission. The primary obstacles to launching such missions are multifaceted, encompassing both technological and logistical challenges.
Technological Challenges
Manned missions demand sophisticated technology beyond what is needed for unmanned missions. For instance, developing a safe and reliable crew module capable of supporting human life in space is a complex task that involves extensive research and development.
Reliable launch systems are crucial for crew safety, including mechanisms to abort missions if necessary. Additionally, effective recovery systems must ensure astronauts return to Earth safely, as the return journey can often be more perilous than the launch.
Sustaining human life in space poses significant challenges, such as managing zero gravity, radiation exposure, and temperature fluctuations. Robust life support systems are essential to provide oxygen, food, waste management, and address psychological factors affecting the crew.
Comprehensive astronaut training is vital. This includes mastering piloting skills, managing emergencies, and coping with extended periods in confined spaces.
Logistical and Financial Aspects
Manned missions are substantially more expensive than unmanned ones, necessitating significant financial investments. India has allocated Rs. 10,000 crore for the Gaganyaan mission, reflecting its financial commitment (Source: Government of India).
Establishing the necessary infrastructure for manned missions involves extensive logistical planning. This includes creating facilities for training, mission control, and vehicle assembly.
India’s Futuristic Approach
The Gaganyaan mission aims to send a three-member crew to space, marking a pivotal step in India’s manned space exploration. The Indian Space Research Organisation (ISRO) is enhancing technology through the development of a heavy-lift launch vehicle and safety systems. Moreover, efforts to encourage private sector participation through IN-SPACe are expected to strengthen the space ecosystem.
Conclusion
Despite the significant challenges, India is making substantial progress towards its first manned mission, Gaganyaan, which could herald a new era in the country’s space exploration capabilities.
