Indian Space Research Organisation

Introduction

The Indian Space Research Organisation (ISRO) is India’s primary space agency, responsible for developing and implementing India’s space program. ISRO has achieved several significant milestones in space exploration, including successful interplanetary missions and the launch of numerous satellites. ISRO’s vision is to harness space technology for national development while pursuing space science research and planetary exploration. Over the years, ISRO has achieved significant milestones in space exploration, making it one of the world’s leading space agencies.

ISRO has launched several satellites for communication, remote sensing, and meteorology, in addition to developing launch vehicles and carrying out interplanetary missions. With a robust space program, ISRO has contributed significantly to the country’s socio-economic development, including improving weather forecasting, communication, navigation, disaster management, and national security. This article will explore the history, achievements, challenges, and plans of ISRO.

History of ISRO

ISRO was established in 1969, following the successful launch of India’s first satellite, Aryabhata, in 1975. ISRO’s early focus was on developing communication satellites for India’s domestic needs. In 1983, ISRO launched the Rohini satellite, making India the seventh country to launch a satellite using its rocket technology. 

The Indian Space Research Organisation was founded on August 15, 1969, by Vikram Sarabhai, who is considered the father of the Indian space program. Its mission was to develop satellite technology and launch vehicles for national development.

Initially, the ISRO worked under the Department of Atomic Energy, but in 1972, it was made an independent organization. Over the years, the ISRO has grown to become one of the world’s leading space agencies, with a budget of over 1.6 billion USD.

Achievements of ISRO

ISRO has achieved several significant milestones in space exploration, demonstrating India’s growing capabilities in this field. Some of the notable achievements of ISRO are:

Interplanetary missions

ISRO has successfully launched several interplanetary missions, including:

Satellite launches

ISRO has also made significant contributions to satellite launches, including:

Other achievements

ISRO has also achieved other significant milestones, such as:

• Developing and launching India’s first navigation satellite, IRNSS-1A, in 2013.
• Developing and launching the South Asia Satellite, which provides communication and disaster management services to several countries in the region.

Remote Sensing

ISRO has developed a robust remote sensing capability, launching several satellites for earth observation, meteorology, and environmental monitoring. ISRO’s remote sensing satellites provide valuable data and images, enabling better crop management, disaster management, weather forecasting, and natural resource mapping.

High-resolution images of the earth’s surface are available from the Cartosat series of satellites, which ISRO developed. ISRO’s INSAT series of satellites provide communication and meteorological services, enabling better disaster management and weather forecasting.

Challenges faced by ISRO

ISRO’s journey in space exploration has not been without challenges. Despite achieving several milestones, ISRO has faced several setbacks and challenges along the way. Here are some of the challenges faced by ISRO.

Technical Challenges

Space exploration is a complex and challenging endeavor that requires cutting-edge technology, precision engineering, and rigorous testing. ISRO has faced several technical challenges in developing launch vehicles, satellites, and interplanetary missions.

ISRO’s ambitious plans to develop a reusable launch vehicle and a human spaceflight program are still in the developmental phase and require significant research and development efforts. Technical challenges in developing advanced space technologies have led to cost and schedule overruns, delaying some of ISRO’s space missions.

International Competition

ISRO operates in a highly competitive and challenging international space market, dominated by established space agencies such as NASA, ESA, and Roscosmos. These space agencies have decades of experience and significant resources, enabling them to undertake complex and ambitious space missions.

ISRO’s limited budget and resources compared to other space agencies make it challenging to compete in the international space market. However, ISRO’s low-cost space missions have gained international recognition, making it an attractive partner for other space agencies.

Geopolitical Challenges

ISRO operates in a highly politicized and sensitive environment, with space technology often linked to national security and military applications. The geopolitical challenges faced by ISRO include the imposition of sanctions, technology denial regimes, and export controls, affecting ISRO’s access to advanced space technology.

• ISRO’s cooperation with other countries in space exploration has also faced geopolitical challenges, with some countries imposing restrictions on space technology transfer and collaboration. However, ISRO’s strategic partnerships with other countries, including Russia, France, and the US, have enabled it to overcome some of these challenges.

Future Plans of the Indian Space Research Organisation

ISRO has ambitious plans to explore the final frontier, including launching more interplanetary missions, developing advanced launch vehicles, and establishing a permanent presence in space. Here are some of ISRO’s plans.

Gaganyaan Mission

A three-person crew will be launched into orbit by the Gaganyaan project at a 400-kilometer altitude for a three-day mission before being safely brought back to land in Indian Ocean waters. 

The project is completed using the best possible strategy, taking into account internal expertise, industry experience, academic & research institutions’ intellectual capacity, and cutting-edge technologies offered by international organizations. The Gaganyaan mission requires the development of several crucial technologies, including human-rated launch vehicles for carrying crew into space safely, life support systems to give them a comfortable environment while they are there, crew emergency escape plans, and evolving crew management elements for crew training, recovery, and rehabilitation. 

To demonstrate the Technology Preparedness Levels before launching the actual Human Space Flight mission, several precursor missions are planned. These demonstrator missions include things like Integrated AirDrop Test (IADT), Pad Abort Test (PAT), and Test Vehicle (TV) flights. Before any manned missions, all systems’ safety and dependability will be demonstrated.

Interplanetary Missions

ISRO has ambitious plans to launch more interplanetary missions, including a mission to Venus and a second mission to Mars. ISRO’s Venus mission is expected to launch in 2024 and will study the planet’s surface and atmosphere.

ISRO has set an expectation to launch its second Mars mission in 2024, which will carry more advanced instruments and technology to study the red planet’s surface and mineralogy. ISRO’s interplanetary missions play a significant role as milestones in space exploration, as they help us to gain a better understanding of the planets in our solar system.

Small Satellite Launch Vehicle

ISRO designed the Small Satellite Launch Vehicle (SSLV), which is a cost-effective launch vehicle for carrying smaller satellites for communication, remote sensing, and scientific research. This development is significant for ISRO as it offers a low-cost alternative for satellite launches, allowing more frequent and affordable access to space for commercial and research purposes.

The SSLV is a crucial component of ISRO’s plans to establish a robust space-based communication and navigation system, which is essential for India’s national security and economic development.

Space Exploration and Space Debris

ISRO recognizes the importance of responsible space exploration and the need to address the issue of space debris. To ensure the sustainable use of space and to reduce the negative effects of space debris on space exploration, ISRO has taken a number of steps.

ISRO actively participates in international efforts to address space debris. This includes being a part of the Inter-Agency Space Debris Coordination Committee and collaborating with other space agencies to develop guidelines and best practices for mitigating space debris.

ISRO is also developing technologies to track and monitor space debris, including the Space Situational Awareness Control Center and the Indian Space Surveillance and Tracking System.
