Chapter 8: Problem 56

Write short notes on India's space program.

Short Answer

Expert verified
Briefly describe India's space program, its history, objectives, milestones, and some notable missions. India's space program is led by the Indian Space Research Organization (ISRO) and focuses on satellite-based communication, remote sensing, and meteorological systems. It began in the early 1960s with the establishment of the Indian National Committee for Space Research (INCOSPAR) by Vikram Sarabhai and later formed ISRO in 1969. Its objectives concentrate on addressing India's needs in communication, observation, navigation, and meteorology. Major milestones include the launch of the Indian Remote Sensing (IRS) satellite system in 1988, and the development of the Polar Satellite Launch Vehicle (PSLV) in 1993, and Geosynchronous Satellite Launch Vehicle (GSLV). Notable missions include Chandrayaan-1 (2008), Mars Orbiter Mission (2013), Indian Regional Navigation Satellite System (2018), and Chandrayaan-2 (2019).

Step by step solution

01

Introduction

India's space program, led by the Indian Space Research Organization (ISRO), plays a crucial role in the nation's development through satellite-based communication, remote sensing, and meteorological systems. Here, we will briefly outline the history and evolution of India's space program, its objectives and milestones, and some of its notable missions.
02

History

India's space program began in the early 1960s with the establishment of the Indian National Committee for Space Research (INCOSPAR) by Vikram Sarabhai. Later in 1969, Indian Space Research Organization (ISRO) was formed as a successor to INCOSPAR. The first Indian satellite, Aryabhata, was launched in 1975 with the help of the Soviet Union. Over the years, India has developed various satellite systems, launch vehicles, and executed successful space missions.
03

Objectives and Milestones

India's space program aims to address the nation's needs in various sectors, including communication, observation, navigation, and meteorology. Some major milestones include the launch of the Indian Remote Sensing (IRS) satellite system in 1988, the development of the Polar Satellite Launch Vehicle (PSLV) in 1993, and later the Geosynchronous Satellite Launch Vehicle (GSLV).
04

Notable Missions

India has undertaken several notable missions in its space program journey. Here are a few: 1. Chandrayaan-1 (2008): India's first lunar mission equipped with instruments to study the lunar surface and discovered evidence of water molecules on the moon. 2. Mars Orbiter Mission (MOM, 2013): Also known as "Mangalyaan," this mission marked India's first interplanetary venture and made India the first Asian country to enter Mars' orbit and the fourth in the world. 3. Indian Regional Navigation Satellite System (IRNSS, 2018): A set of seven satellites, also known as 'NavIC,' provides India with an independent regional satellite navigation system. 4. Chandrayaan-2 (2019): India's second lunar mission aimed to explore the moon's uncharted south polar region. Overall, India's space program has demonstrated impressive capabilities, achievements, and a continuous commitment to expanding their space frontiers.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

ISRO
The Indian Space Research Organisation (ISRO) is the heart and soul of India's space explorations. Since its establishment in 1969, ISRO has evolved rapidly from its modest beginnings, fueled by the vision of its founding father, Dr. Vikram Sarabhai. Initially, ISRO took over the responsibilities of the Indian National Committee for Space Research (INCOSPAR) and has not looked back since.

ISRO's main objectives include the advancement of space technology and its application to meet the various social and economic needs of India.
  • Launching satellites for communication and meteorology
  • Exploring celestial bodies through missions
  • Developing launch vehicles and rockets
With its cost-effective and home-grown innovations, ISRO has propelled India as a major player in the global space arena.
Satellite Systems
Satellite systems are the cornerstone of ISRO鈥檚 groundbreaking work, supporting a plethora of applications that drive India鈥檚 infrastructure and services. Starting with the historic launch of Aryabhata in 1975, India has developed its satellite systems to serve specific purposes, such as communication, navigation, and earth observation.

Some pivotal satellite systems include:
  • Indian National Satellite System (INSAT): Boosts telecommunications, television broadcasting, and meteorology.
  • Indian Remote Sensing Satellites (IRS): Offers vital data for agriculture, forestry, land-use planning, and disaster management. These were first deployed in 1988.
  • NavIC (IRNSS): India鈥檚 very own satellite-based navigation service providing precise location data.
Each of these systems supports India鈥檚 self-reliance in space technology and has widespread applications that enhance the country鈥檚 progress.
Chandrayaan Missions
The Chandrayaan missions mark India's audacious steps towards lunar exploration. The term "Chandrayaan" translates to "mooncraft" in Hindi, which perfectly encapsulates India's ambition to uncover the moon鈥檚 secrets.

  • Chandrayaan-1: Launched in 2008, this was India's first lunar mission designed to study the moon鈥檚 chemical, mineral, and surface features. It made groundbreaking discoveries, including the presence of water molecules on the moon.
  • Chandrayaan-2: Launched in 2019, this mission aimed higher, seeking to explore the moon's south pole鈥攁 region not extensively investigated before. While the lander faced challenges, its orbiter continues to function, sending valuable data.
The Chandrayaan missions are a testament to ISRO's persistent endeavor to contribute valuable knowledge to space science and exploration.
Mars Orbiter Mission
The Mars Orbiter Mission (MOM), affectionately known as "Mangalyaan," signifies one of ISRO's most celebrated achievements. Launched in 2013, this mission was monumental as India became the first Asian nation to reach Mars' orbit. Mangalyaan's objectives were to develop the technology required for interplanetary missions, and it achieved:
  • The study of Martian surface, morphology, and atmosphere
  • The collected data about the planet's mineralogy and its atmosphere
  • The design and real-time operations of an orbiter around another planet
Mangalyaan鈥檚 success was particularly noteworthy because it was accomplished on a shoestring budget, making it one of the most economical missions to Mars. It opened the doors for further interplanetary exploration opportunities for India.
