For detailed information about Chandrayaan-3 Mission click here.

Upcoming Missions of ISRO

The following are some of the upcoming ISRO Missions:

Indian Space Research Organisation (ISRO) Background

Dr. Vikram Sarabhai, the man responsible for launching India’s space project in the 1960s, started space research activities there. Three main elements have been a part of the Indian space project from the beginning: communication and remote sensing satellites, the space transportation system, and application programmes.

Dr. Ramanathan and Dr. Sarabhai established INCOSPAR (Indian National Committee for Space Research). SITE, or Satellite Instructional Television Experiment, was run in 1975–1976. It was referred to as “the largest sociological experiment ever.” Following it was the “Kheda Communications Project (KCP),” which acted as a field laboratory for need-based and location-specific programme transmission in Gujarat.

The Department of Space was founded in 1972, although INCOSPAR was renamed the Indian Space Research Organisation in 1969 (now, ISRO is a division of the Department of Science). The following are the pivotal moments in ISRO history:

• The greatest sociological experiment ever done, SITE (Satellite Instructional Television Experiment), took place in 1975–1976.
• Gujarat is where the Kheda Communications Project was founded. The undertaking served as a field lab.
• In addition, ISRO created and launched Aryabhata, the first Indian spacecraft, utilising a Soviet launch vehicle.
• In 1980, SLV-3 made its maiden successful flight.
• Apple introduced the first satellite-based communication system.
• Antrix Corporation Limited (ACL), the ISRO’s marketing division, was established to advance and sell the use of space products.
• ISRO built a few specialised centres. These include the Vikram Sarabhai Space Centre (VSSC) and the Liquid Propulsion Systems Centre (LPSC) in Thiruvananthapuram, as well as the National Remote Sensing Centre (NRSC) in Hyderabad, the Space Applications Centre (SAC) in Ahmedabad, and the Satish Dhawan Space Centre (SDSC-SHAR) in Sriharikota.

ISRO Achievements

Since the Indian Space Research Organisation was founded, its employees have worked very hard to accomplish its goals. The following missions were successfully launched by ISRO:

Communication Satellites

With nine operational communication satellites in Geostationary orbit launched by the Indian Space Research Organisation (ISRO), the Indian National Satellite (INSAT) system, which went into service in 1983 with the commissioning of INSAT-1B, is one of the largest domestic communication satellite systems in the Asia-Pacific region.

The communications market in India underwent a significant transition as a result, which it sustained throughout time. The INSAT system supports telecommunications, satellite news gathering, television transmission, societal applications, weather forecasting, disaster warning, and search and rescue activities. Here are some of ISRO’s key communication satellites:

Earth Observation Satellites

Since the launch of IRS-1A in 1988, ISRO has launched a number of operational remote-sensing satellites. One of the largest satellite constellations for remote sensing is now run by India. Different instruments have been constructed and flown onboard to serve various national and international purposes in order to deliver the essential data at diversified temporal, spectral, and geographical resolutions. These satellites’ data are then utilised by ISRO for a variety of purposes, including disaster management, the management of ocean resources, forestry, environmental protection, mineral prospecting, rural development, urban planning, water resources, and agriculture.

The table below includes a list of ISRO’s significant Earth observation satellites, together with information about their launch vehicle and the date of launch:

Navigation Satellites

The Airport Authority of India (AAI) and ISRO are collaborating to build the GPS Aided Geo Augmented Navigation (GAGAN) system in order to meet the requirements of Civil Aviation. Indian Regional Navigation Satellite System (IRNSS) is a regional satellite navigation system being established by ISRO in order to satisfy customer requirements for positioning, navigation, and timing services based on indigenous technology.

Experimental Satellites

Many small satellites, usually for research, have been launched by ISRO. This experiment makes use of payload development, orbit controls, atmospheric research, remote sensing, and recovery technology. The following is a list of the key experimental satellites that ISRO has launched:

Small Satellites

The small satellite project will soon offer a platform for standalone payloads for science and earth imaging missions. The Indian Space Research Organisation (ISRO) has developed two different bus types, the Indian Mini Satellite -1 (IMS-1) and Indian Mini Satellite – 2 (IMS-2), to offer a versatile platform for different payloads.

Here is a list of the small satellites that ISRO has launched:

Space Science & Exploration Satellites

Satellites fall within this group: The first dedicated Indian astronomy mission, AstroSat, studies celestial sources simultaneously in the X, optical, and UV spectral bands. The true first interplanetary mission of ISRO, the Mars Orbiter Mission (MOM), was launched on November 5, 2013. Both Chandrayaan-1 and Chandrayaan-2, India’s first and second moon missions, included an orbiter, a lander, a rover, and other components.

Academic Institute Satellites

Educational institutions have been impacted by ISRO operations, such as the development of connectivity, remote sensing, and astronomy satellites. Universities and other organisations have been more interested in creating experimental student satellites as a result of the Chandrayaan-1 launch.

Here is a table listing the ISRO-launched academic institute satellites:

Scramjet (Supersonic Combusting Ramjet) Engine

The Supersonic Combusting Ramjet Engine Test, or Scramjet, was successfully completed by ISRO in August 2016. The fuel for the Scramjet engine is hydrogen, while the oxidizer is oxygen from the surrounding air. With a longer flight time, the new propulsion system will enhance ISRO’s reusable launch vehicle.

Indian Space Research Organisation (ISRO) Objective

ISRO has the ambition to develop space technology for the benefit of the country and to conduct planetary exploration and space science research. The following are the main goals of ISRO:

• The Small Satellite Launch Vehicle (SSLV), Geosynchronous Satellite Launch Vehicle (GSLV), and Polar Satellite Launch Vehicle (PSLV) operational flights.
• To plan, create, and launch communication and earth observation satellites.
• Designing and developing fresh approaches to space transportation is another important goal of ISRO.
• To create satellites for planetary exploration and space science, as well as satellite navigation systems.
• To create tools for more accurate earth observation.
• To develop a system based on space for use in society.
• Developing proper training, education, and capacity-building programmes for students interested in space technology is one of ISRO’s main goals.

Indian Space Research Organisation (ISRO) Challenges and Opportunities

Even though ISRO’s success stories are celebrated all over the world, the organisation still faces obstacles in accomplishing its objectives. The Indian Space Programme has the following problems and opportunities:

• India is not in a situation where it is facing specific security and development concerns since it is a developing nation. For instance, ISRO is called into question and forced to defend the funding for missions that need a lot of work but have little to do with development.
• Since China tested an anti-satellite missile (ASAT) in 2007, the country has upped the threat level. In addition to the one on the ground, it can start in space. There have been military weaknesses since India relied on satellites like MOM.
• The US or other nations must cooperate with the DRDO while it develops a missile.
• China launched the satellite in 2011 and 2012 to target Pakistan and Sri Lanka.

Indian Space Research Organisation (ISRO) UPSC

One of the most significant scientific institutions in the nation and a recent boon to India is ISRO. The ISRO-launched satellites have been successful in gathering the needed information, making them a crucial component of India’s development. Being so important for the nation, it is also a key subject for UPSC hopefuls because many questions from the ISRO UPSC notes are asked in the IAS Exam.

History of ISRO

Earlier scientists like S.K. Mitra, C.V. Raman, and Meghnad Saha used to carry space programs. Later Vikram Sarabhai founded Physical Research Laboratory at Ahmedabad. Homi Bhabha established the Tata Institute of Fundamental Research in 1945.

In 1962, the urge of the Indian National Committee for Space Research (INCOSPAR) was established by PM Jawaharlal Nehru. Later in 1963 sounding rocket was launched from Thumba Equatorial Rocket Launching Station (TERLS). On 15th August 1969 Indian Space Research Organization (ISRO) was established.

One of the biggest landmarks was seen when ISRO sent its first satellite ‘Aryabhatta’ with a Soviet Rocket in the year 1975. Later, in the year 1982, Indian National Satellite (INSAT-1A) was launched. ISRO collaborated with the Soviet Union to conduct the first manned mission in 1984 in which Rakesh Sharma was a part of it.

In 1994, ISRO conducted the launch of Polar Satellite Launch Vehicle (PSLV), the third generation of launch vehicles. Moving to 2001, ISRO managed to successfully launch GSLV D1. ISRO stepped on the moon in the year 2008 and in 2014 ISRO managed to land on Mars.

Role of ISRO in the Advancement of India

ISRO’s role in the Advancement of India cannot be forgotten from Aryabhatta to NavIC. Here are some of the projects that became a landmark and helped India in modernization.

Achievements of ISRO

India is prideful to have ISRO as it has given us many reasons to feel pride. ISRO has always delivered whenever India wanted to do something, ISRO never failed to surprise us. Be it the cheapest landing on Mars or finding water on Moon, ISRO has done many works. Here are some of the Achievements that ISRO must be proud of.

• Mars Orbital Mission (MOM) – The Mars Orbital Mission or Mangalyan is one of the biggest successes for ISRO. ISRO achieved the target of reaching Mars in the most economical way and became the first space agency to reach mars in the first attempt. The budget was 450 crores which is less than many Hollywood movies making India the 4 th country to reach on Mars. There is a movie made to highlight the landing of Mangalyan naming Mission Mangal.
• 104 satellites in 1 Mission – ISRO in 2017 created history as it launched 104 satellites in 1 goes. ISRO used its Polar Satellite Launch Vehicle to perform this target. Among 104 satellites, 101 were foreign and 3 were Indian.
• Water on Moon – India’s Chandrayan I mission was launched on 14 th November, 2008. It landed on the south pole of the moon and founded hydroxyl absorption lines on the surface. It was later confirmed by NASA, when M 3 sent data on 25 th September, 2009.

Budget Allocations

If an organization is this big that the world praises and hails its works, then it will definitely need a good amount of budget. Indian government never failed to provide that. Although, the Mars Orbital Mission was inexpensive but now the budget is not a big issue. The 8,228 Crore expenditure which was allocated for 2020-21, increased to 13,949 Crore for 2021-22. A new public sector named New Space India Limited (NSIL) got an allocation of Rs 700 crores for the same term.

ISRO – The Pride of India

Mentioning ISRO as a pride of India is no doubt a big statement. ISRO is something that India will always boast of. ISRO has been regarded as one of the fastest-growing space agencies in the world and can change the space race. Below mentioned points tell why India considers ISRO a pride.

• ISRO’s mars mission was so cheap that it took only Rs 7/km to reach mars.
• SUPARCO of Pakistan was established 8 years earlier than ISRO but the capabilities of launching satellite will be developed by 2040.
• ISRO is planning to launch Human Spaceflight program in 2023 which might make India the 4 th country to send humans in Space.
• ISRO works closely with Defence Research Development Organization for India’s defence and they have signed an MOU for the upcoming Gaganyan Mission.
• ISRO is also planning to launch its Space Station soon after the Gaganyan mission.

ISRO has always stunned everyone with its unbelievable achievements. However, they have failed many times but it didn’t affect them. ISRO has always learned from the setbacks and just as the diamond shines, it kept shining. The Indian government has also supported ISRO and past few years, the budget allocations are majorly focused. An Indian person sees ISRO scientists as supermen and respects them whenever they get to meet them. ISRO is supposed to compete with NASA in near future and it can be a matter of respect for all of us.

Essay on Aditya L1 in English

Details about aditya l1 mission.

• About Chandrayaan 3 Essay in English for School Students
• चंद्रयान 3 पर हिंदी निबंध और भाषण: Chandrayaan 3 Essay in Hindi for School Students

Why is ISRO’s Aditya L1 Mission So Unique?

• First time spatially resolved solar disk in the near UV band.
• CME dynamics close to the solar disk (~ from 1.05 solar radius) and thereby providing information in the acceleration regime of CME which is not observed consistently.
• On-board intelligence to detect CMEs and solar flares for optimised observations and data volume.
• Directional and energy anisotropy of solar wind using multi-direction observations.

Major Objectives of Aditya L1 Mission

• Understanding Coronal Heating and Solar Wind Acceleration.
• Understanding initiation of Coronal Mass Ejection (CME), flares and near-earth space weather.
• To understand coupling and dynamics of the solar atmosphere.
• To understand solar wind distribution and temperature anisotropy.

Our Sun, the nearest star and the largest object in our solar system, is approximately 4.5 billion years old. It consists of hot, glowing hydrogen and helium gases and is located about 150 million kilometers away from Earth. The Sun is the primary source of energy for our solar system, and life on Earth relies on this solar energy. Additionally, the Sun's gravitational force is responsible for holding all the objects in our solar system together.

The core of the Sun, situated at its central region, reaches incredibly high temperatures, around 15 million degrees Celsius, where a process known as nuclear fusion occurs, providing the Sun's power. In contrast, the visible surface of the Sun, called the photosphere, is relatively cooler, with a temperature of approximately 5,500°C.

Why Is It Important To Study The Sun?

Studying the Sun, our nearest star, offers a unique opportunity to gain insights into stars not only in our Milky Way but also in other galaxies. The Sun is a highly dynamic star, exhibiting eruptive phenomena and releasing vast amounts of energy into the solar system. These solar eruptions, if directed towards Earth, can disrupt near-Earth space environments, affecting spacecraft and communication systems. Early warning systems are crucial to mitigate these potential disturbances.

Furthermore, exposure to such explosive solar events poses risks to astronauts. The Sun's extreme thermal and magnetic phenomena provide a natural laboratory for studying processes that cannot be replicated in a controlled laboratory setting. Hence, studying the Sun serves both as a window into stellar behavior and as a means to understand extreme natural phenomena with practical implications for space exploration and communication.

Why Is It Important To Study The Sun From Space?

The Sun emits a wide range of radiation, including light across various wavelengths, energetic particles, and a magnetic field. Earth's atmosphere and magnetic field act as protective barriers, blocking many harmful radiations, particles, and fields from reaching the planet's surface. Consequently, instruments on Earth cannot detect these types of radiation, making it impossible to conduct solar studies based on them.

To overcome this limitation, scientists must conduct observations from outside Earth's atmosphere, specifically from space. This approach enables the study of solar radiations and other phenomena that are inaccessible from the Earth's surface. Additionally, to understand the behavior of solar wind particles and the Sun's magnetic field as they travel through interplanetary space, measurements need to be taken from a location far removed from the influence of Earth's magnetic field.

Is Aditya L1 A Complete Mission To Study The Sun?

The answer to whether Aditya-L1 or any space mission can fully address the study of various solar phenomena is a resounding 'NO.' This limitation arises from the constraints of spacecraft, including mass, power, and volume, which restrict the number and capacity of scientific instruments that can be sent into space. Aditya-L1, for instance, will conduct all its measurements from Lagrange point L1.

One significant limitation is that many solar phenomena, such as explosive eruptions, exhibit multi-directional characteristics, making it impossible for Aditya-L1 alone to study their directional distribution of energy. Another potential solution lies in Lagrange point L5, which offers a valuable perspective for studying Earth-directed CME events and assessing space weather.

Aditya L1 Payloads Details

ISRO’s first observatory class space based solar mission has a total of seven payloads on-board with four of them carrying out remote sensing of the Sun and three of them carrying in-situ observation.
