Search for Life on Other Planets: India’s Contribution in Space Research

The search for life on other planets has been one of the most intriguing scientific goals for nations worldwide. With advancements in space technology and the discovery of numerous exoplanets (planets outside our solar system), the question of whether life exists beyond Earth has become a key focus of research. India, through its space research organization ISRO (Indian Space Research Organisation), has made significant contributions to space exploration and is advancing the global search for extraterrestrial life.

India’s Space Research Milestones in the 21st Century

India has made impressive strides in space research, particularly in the 21st century. Key missions and developments by ISRO have contributed to the global understanding of space and the search for life on other planets.

1. Mars Orbiter Mission (Mangalyaan)

• Launch Date: November 5, 2013
• Objective: To study the Martian surface, atmosphere, and mineral composition, as well as search for signs of water, which is considered essential for life.
• Significance:
  • India became the first Asian country to reach Mars orbit and the first in the world to do so on its maiden attempt.
  • Mangalyaan provided important data about the Martian atmosphere and surface, helping scientists understand its potential to support life.
  • The mission highlighted India’s growing capabilities in space exploration and its contribution to the global search for extraterrestrial life.

2. Chandrayaan Missions

• Chandrayaan-1 (2008):
  • India’s first lunar mission aimed at mapping the Moon and discovering the presence of water on its surface. Chandrayaan-1 found evidence of water molecules on the Moon, which has significant implications for understanding planetary habitability and life.
• Chandrayaan-2 (2019):
  • The second mission focused on exploring the Moon’s south pole region. While the Vikram lander lost communication, the orbiter continues to send data, expanding our knowledge of the Moon’s geology and water resources, which can be crucial for future space missions, including those exploring life on other planets.

3. Astrobiology Research

• ISRO’s collaboration with international space agencies has also contributed to astrobiology—the study of life in space. By studying the extreme environments on Earth (like deep oceans and volcanic regions) and the conditions on other planets, scientists can make inferences about the possibility of life elsewhere in the universe.

4. Gaganyaan Mission (Planned)

• Objective: India’s upcoming human space mission, planned for 2024, will involve sending Indian astronauts (Gagannauts) into space. This mission aims to explore deep space and could contribute to future missions focused on the search for extraterrestrial life.
• Potential Contribution: By sending humans into space for longer durations, this mission will provide valuable data about human survival in space and contribute to the technology needed for exploring distant planets and moons where life might exist.

India’s Role in the Global Search for Life

While India’s own missions have focused on exploring planets like Mars and the Moon, ISRO’s efforts are also aligned with the global scientific community’s search for extraterrestrial life. India is an active participant in various international collaborations such as:

• Participation in Exoplanet Research:
  • ISRO collaborates with space agencies like NASA, ESA (European Space Agency), and others in the search for exoplanets, particularly in the habitable zone where liquid water can exist. The discovery of exoplanets is critical in the search for life, and India’s participation in these studies enhances the global research effort.
• Space Telescopes:
  • India has been a part of international missions that involve space telescopes, like the James Webb Space Telescope (launching soon), which aims to search for habitable planets in other star systems.
• India’s Contribution to Astrobiology:
  • The study of how life could exist on other planets, especially in extreme environments, is being enhanced by India’s participation in international astrobiology research programs. Indian scientists are contributing to understanding how life might adapt to the harsh conditions found on planets like Mars, Venus, and exoplanets.

Make in India and Space Exploration

The Make in India initiative has also played a significant role in space exploration. Under this initiative, India is increasing its self-reliance in space technology by developing indigenous spacecraft, satellites, and technologies. This includes manufacturing spacecraft parts, space instruments, and even launching rockets and satellites from within India. By building a strong space infrastructure, India can reduce its dependence on other countries and lead more missions to explore space, including the search for extraterrestrial life.
