The Indian Space Research Organisation (ISRO, //; Sanskrit: भारतीय अंतरिक्ष अनुसंधान संगठन Bhāratīya Antarikṣa Anusandhāna Saṅgaṭhana) is the primary space agency of India. ISRO is amongst the largest government space agencies in the world. Its primary objective is to advance space technology and use its applications for national benefit.
Established in 1969, ISRO superseded the erstwhile Indian National Committee for Space Research (INCOSPAR). Headquartered in Bengaluru, ISRO is under the administrative control of the Department of Space, Government of India.
Since its establishment, ISRO has achieved numerous milestones. It built India's first satellite, Aryabhata, which was launched by the Soviet Union on 19 April in 1975. In 1980, Rohini became the first satellite to be placed in orbit by an Indian-made launch vehicle, SLV-3. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites and earth observation satellite. On 22 October in 2008, Chandrayaan-1, India sent its first mission to the Moon. Over the years, ISRO has conducted a variety of operations for both Indian and foreign clients. ISRO's satellite launch capability is mostly provided by indigenous launch vehicles and launch sites. In 2008, ISRO successfully launched its first lunar probe, Chandrayaan-1, while future plans include indigenous development of GSLV, manned space missions, further lunar exploration, mars exploration and interplanetary probes. ISRO has several field installations as assets, and cooperates with the international community as a part of several bilateral and multilateral agreements. 5 November 2013, ISRO launched its Mars Orbiter Mission, which is currently en route to Mars.
The June 2014 launch of five foreign satellites by the PSLV (Polar Satellite Launch Vehicle) became an impetus for PM Narendra Modi to proclaim his ability of showcasing India as a champion of its neighboring countries, and thus envisioning a developement of a satellite which will be used by its neighbouring countries, as a gift from India.
Modern space research in India is most visibly traced to the 1920s, when the scientist S. K. Mitra conducted a series of experiments leading to the sounding of the ionosphere by application of ground based radio methods in Calcutta. Later, Indian scientists like C.V. Raman and Meghnad Saha contributed to scientific principles applicable in space sciences. However, it was the period after 1945 which saw important developments being made in coordinated space research in India. Organised space research in India was spearheaded by two scientists: Vikram Sarabhai—founder of the Physical Research Laboratory at Ahmedabad—and Homi Bhabha, who had played a role in the establishment of the Tata Institute of Fundamental Research in 1945. Initial experiments in space sciences included the study of cosmic radiation, high altitude and airborne testing of instruments, deep underground experimentation at the Kolar mines—one of the deepest mining sites in the world – and studies of the upper atmosphere. Studies were carried out at research laboratories, universities, and independent locations.
In 1950, the Department of Atomic Energy was founded with Homi Bhabha as its secretary. The Department provided funding for space research throughout India. During this time, tests continued on aspects of meteorology and the Earth's magnetic field, a topic which was being studied in India since the establishment of the observatory at Colaba in 1823. In 1954, the Uttar Pradesh state observatory was established at the foothills of the Himalayas. The Rangpur Observatory was set up in 1957 at Osmania University, Hyderabad. Both these facilities enjoyed the technical support and scientific cooperation of the United States of America. Space research was further encouraged by the technically inclined Prime Minister of India, Jawaharlal Nehru. In 1957, the Soviet Union successfully launched Sputnik and opened up possibilities for the rest of the world to conduct a space launch. INCOSPAR was found in 1962 with Vikram Sarabhai as its chairman.
The prime objective of ISRO is to develop space technology and its application to various national tasks. The Indian space programme was driven by the vision of Dr Vikram Sarabhai, considered the father of Indian Space Programme. As he said in 1969:
|“||There are some who question the relevance of space activities in a developing nation. To us, there is no ambiguity of purpose. We do not have the fantasy of competing with the economically advanced nations in the exploration of the Moon or the planets or manned space-flight. But we are convinced that if we are to play a meaningful role nationally, and in the community of nations, we must be second to none in the application of advanced technologies to the real problems of man and society.||”|
As the former Indian President Dr APJ Abdul Kalam said:
|“||Many individuals with myopic vision questioned the relevance of space activities in a newly independent nation, which was finding it difficult to feed its population. Their vision was clear if Indians were to play meaningful role in the community of nations, they must be second to none in the application of advanced technologies to their real-life problems. They had no intention of using it as a means of displaying our might.||”|
India's economic progress has made its space programme more visible and active as the country aims for greater self-reliance in space technology. Hennock etc. hold that India also connects space exploration to national prestige, further stating: "This year India has launched 11 satellites, including nine from other countries—and it became the first nation to launch 10 satellites on one rocket." ISRO has successfully put into operation two major satellite systems namely Indian National Satellites (INSAT) for communication services and Indian Remote Sensing (IRS) satellites for management of natural resources. ISRO has also developed the PSLV for launching IRS type of satellites and GSLV for launching INSAT type of satellites.
During the 1960s and 1970s, India initiated its own launch vehicle programme owing to geopolitical and economic considerations. In the 1960s–1970s, the country successfully developed a sounding rockets programme, and by the 1980s, research had yielded the Satellite Launch Vehicle-3 and the more advanced Augmented Satellite Launch Vehicle (ASLV), complete with operational supporting infrastructure. ISRO further applied its energies to the advancement of launch vehicle technology resulting in the creation of PSLV and GSLV technologies.
The Satellite Launch Vehicle, usually known by its abbreviation SLV or SLV-3 was a 4-stage solid-propellant light launcher. It was intended to reach a height of 500 km and carry a payload of 40 kg. Its first launch took place in 1979 with 2 more in each subsequent year, and the final launch in 1983. Only two of its four test flights were successful.
The Augmented Satellite Launch Vehicle, usually known by its abbreviation ASLV was a 5-stage solid propellant rocket with the capability of placing a 150 kg satellite into LEO. This project was started by the ISRO during the early 1980s to develop technologies needed for a payload to be placed into a geostationary orbit. Its design was based on Satellite Launch Vehicle. The first launch test was held in 1987, and after that 3 others followed in 1988, 1992 and 1994, out of which only 2 were successful, before it was decommissioned.
The Polar Satellite Launch Vehicle, usually known by its abbreviation PSLV, is an expendable launch system developed to allow India to launch its Indian Remote Sensing (IRS) satellites into Sun synchronous orbits, a service that was, until the advent of the PSLV, commercially viable only from Russia. PSLV can also launch small satellites into geostationary transfer orbit (GTO). The reliability and versatility of the PSLV is proven by the fact that it has launched 65 satellites / spacecraft ( 30 Indian and 35 Foreign Satellites) into a variety of orbits so far. In April 2008, it successfully launched 10 satellites at once, breaking a world record held by Russia.
On 30 June 2014, the PSLV flew its 25th consecutive successful launch mission, delivering a payload of five foreign satellites into orbit. Its only failure in 26 flights was its maiden voyage in September 1993, providing the rocket with a 96 percent success rate.
The Geosynchronous Satellite Launch Vehicle, usually known by its abbreviation GSLV, is an expendable launch system developed to enable India to launch its INSAT-type satellites into geostationary orbit and to make India less dependent on foreign rockets. At present, it is ISRO's heaviest satellite launch vehicle and is capable of putting a total payload of up to 5 tons to Low Earth Orbit. The vehicle is built by India with the cryogenic engine purchased from Russia while the ISRO develops its own engine programme.
In a setback for ISRO, the attempt to launch the GSLV, GSLV-F06 carrying GSAT-5P, failed on 25 December 2010. The initial evaluation implies that loss of control for the strap-on boosters caused the rocket to veer from its intended flight path, forcing a programmed detonation. Sixty-four seconds into the first stage of flight, the rocket began to break up due to the acute angle of attack. The body housing the 3rd stage, the cryogenic stage, incurred structural damage, forcing the range safety team to initiate a programmed detonation of the rocket.
On 5 January 2014, GSLV D5 successfully launched GSAT-14 into intended orbit. This also marked first successful flight using indigenous cryogenic engine, making India sixth country in the world to have this technology.
The Geosynchronous Satellite Launch Vehicle Mark-III is a launch vehicle currently under development by the Indian Space Research Organisation. It is intended to launch heavy satellites into geostationary orbit, and will allow India to become less dependent on foreign rockets for heavy lifting. The rocket, though the technological successor to the GSLV, however is not derived from its predecessor.
India's first satellite, the Aryabhata, was launched by the Soviet Union on 19 April 1975 from Kapustin Yar using a Cosmos-3M launch vehicle. This was followed by the Rohini series of experimental satellites which were built and launched indigenously. At present, ISRO operates a large number of earth observation satellites.
INSAT (Indian National Satellite System) is a series of multipurpose geostationary satellites launched by ISRO to satisfy the telecommunications, broadcasting, meteorology and search-and-rescue needs of India. Commissioned in 1983, INSAT is the largest domestic communication system in the Asia-Pacific Region. It is a joint venture of the Department of Space, Department of Telecommunications, India Meteorological Department, All India Radio and Doordarshan. The overall coordination and management of INSAT system rests with the Secretary-level INSAT Coordination Committee.
Indian Remote Sensing satellites (IRS) are a series of earth observation satellites, built, launched and maintained by ISRO. The IRS series provides remote sensing services to the country. The Indian Remote Sensing Satellite system is the largest constellation of remote sensing satellites for civilian use in operation today in the world. All the satellites are placed in polar Sun-synchronous orbit and provide data in a variety of spatial, spectral and temporal resolutions to enable several programmes to be undertaken relevant to national development. The initial versions are composed of the 1 (A,B, C, D) nomenclature. The later versions are named based on their area of application including OceanSat, CartoSat, Resource Sat.
ISRO currently operates two Radar Imaging Satellites. RISAT-1 was launched from Sriharikota Spaceport on 26 April 2012 on board a PSLV.RISAT-1 carries a C-band Synthetic Aperture Radar (SAR) payload, operating in a multi-polarisation and multi-resolution mode and can provide images with coarse, fine and high spatial resolutions. India also operates RISAT-2 which was launched in 2009 and acquired from Israel at a cost $110 million.
ISRO has also launched a set of experimental geostationary satellites known as the GSAT series. Kalpana-1, ISRO's first dedicated meteorological satellite, was launched by the Polar Satellite Launch Vehicle on 12 September 2002. The satellite was originally known as MetSat-1. In February 2003 it was renamed to Kalpana-1 by the Indian Prime Minister Atal Bihari Vajpayee in memory of Kalpana Chawla – a NASA astronaut of Indian origin who perished in Space Shuttle Columbia.
ISRO has also successfully launched the Indo-French satellite SARAL on 25 February 2013, 12:31 UTC.SARAL or Satellite with ARgos and ALtiKa is a cooperative altimetry technology mission. It is being used for monitoring the oceans surface and sea-levels.AltiKa will measure ocean surface topography with an accuracy of 8 mm, against 2.5 cm on average using current-generation altimeters, and with a spatial resolution of 2 km.
In June 2014, India launched Singapore's first nano satellite (VELOX-I), Canada's (CAN-X5), AISAT of Germany and French Earth Observation Satellite SPOT-7 besides its primary payload of 714 kg via the PSLV-C23.
The Ministry of Civil Aviation has decided to implement an indigenous Satellite-Based Regional GPS Augmentation System also known as Space-Based Augmentation System (SBAS) as part of the Satellite-Based Communications, Navigation and Surveillance (CNS)/Air Traffic Management (ATM) plan for civil aviation. The Indian SBAS system has been given an acronym GAGAN – GPS Aided GEO Augmented Navigation. A national plan for satellite navigation including implementation of Technology Demonstration System (TDS) over the Indian air space as a proof of concept has been prepared jointly by Airports Authority of India (AAI) and ISRO. TDS was successfully completed during 2007 by installing eight Indian Reference Stations (INRESs) at eight Indian airports and linked to the Master Control Centre (MCC) located near Bengaluru.
The first GAGAN navigation payload has been fabricated and it was proposed to be flown on GSAT-4 during Apr 2010. However, GSAT-4 was not placed in orbit as GSLV-D3 could not complete the mission. Two more GAGAN payloads will be subsequently flown, one each on two geostationary satellites, GSAT-8 and GSAT-10. On 12 May 2012, ISRO announced the successful testing of its indigenous cryogenic engine for 200 seconds for its forthcoming GSLV-D5 flight.
IRNSS is an independent regional navigation satellite system being developed by India. It is designed to provide accurate position information service to users in India as well as the region extending up to 1500 km from its boundary, which is its primary service area. IRNSS will provide two types of services, namely, Standard Positioning Service (SPS) and Restricted Service (RS) and is expected to provide a position accuracy of better than 20 m in the primary service area. It is an autonomous regional satellite navigation system being developed by Indian Space Research Organisation which would be under total control of Indian government. The requirement of such a navigation system is driven by the fact that access to Global Navigation Satellite Systems like GPS are not guaranteed in hostile situations. ISRO plans to launch the constellation of satellites between 2012 and 2014.
ISRO on 1 July 2013, at 23:41Hrs IST launched from Sriharikota the First Indian Navigation Satellite the IRNSS-1A. The IRNSS-1A was launched aboard PSLV-C22. The constellation would be comprising 7 satellites of I-1K bus each weighing around 1450 Kilograms, with three satellites in the Geostationary Earth Orbit (GEO) and 4 in Geosynchronous Earth Orbit(GSO). The constellation would be completed around 2015.
On 4 April 2014, at 17:14 Hrs IST ISRO has launched IRNSS-1B from Sriharikota, its second of seven IRNSS series. After 19 mins of launch PSLV-C24 has successfully injected into its orbit.
The Indian Space Research Organisation has proposed a budget of 124 billion (US$2.1 billion) for its human spaceflight programme. According to the Space Commission which recommended the budget, an unmanned flight will be launched after 7 years of final approval. and a manned mission will be launch after 7 years of funding. If realised in the stated time-frame, India will become the fourth nation, after the USSR, US and China, to successfully carry out manned missions indigenously.
The Space Capsule Recovery Experiment (SCRE or more commonly SRE or SRE-1) is an experimental Indian spacecraft which was launched using the PSLV C7 rocket, along with three other satellites. It remained in orbit for 12 days before re-entering the Earth's atmosphere and splashing down into the Bay of Bengal. The SRE-1 was designed to demonstrate the capability to recover an orbiting space capsule, and the technology for performing experiments in the microgravity conditions of an orbiting platform. It was also intended to test thermal protection, navigation, guidance, control, deceleration and flotation systems, as well as study hypersonic aero-thermodynamics, management of communication blackouts, and recovery operations. ISRO also plans to launch SRE-2 and SRE-3 in the near future to test advanced re-entry technology for future manned missions.
ISRO will set up an astronaut training centre in Bengaluru to prepare personnel for flights on board the crewed vehicle. The centre will use simulation facilities to train the selected astronauts in rescue and recovery operations and survival in zero gravity, and will undertake studies of the radiation environment of space. ISRO will build centrifuges to prepare astronauts for the acceleration phase of the mission. It also plans to build a new Launch pad to meet the target of launching a manned space mission in 7 years of funding clearance. This would be the third launchpad at the Satish Dhawan Space Centre, Sriharikota.
The Indian Space Research Organisation (ISRO) is working towards a maiden manned Indian space mission vehicle that can carry three astronauts for seven days in a near earth orbit. The Indian manned spacecraft temporarily named as Orbital Vehicle intends to be the basis of indigenous Indian human spaceflight programme. The capsule will be designed to carry three people, and a planned upgraded version will be equipped with a rendezvous and docking capability. In its maiden manned mission, ISRO's largely autonomous 3-ton capsule will orbit the Earth at 400 km in altitude for up to seven days with a two-person crew on board. The crew vehicle would launch atop of ISRO's GSLV Mk II, currently under development. The GSLV Mk II features an indigenously developed cryogenic upper-stage engine. The first test of the cryogenic engine, held on 15 April 2010, failed as the cryogenic phase did not perform as expected and rocket deviated from the planned trajectory. However the second test of the indigenous cryogenic engine was successful on 5 January 2014.
India's space era dawned when the first two-stage sounding rocket was launched from Thumba in 1963. Even before this, noteworthy contributions were made by the Indian scientists in the following areas of space science research:
With the advent of the Indian space programme, emphasis was laid on indigenous, self-reliant and state-of-the-art development of technology for immediate practical applications in the fields of space science research activities in the country.
There is a national balloon launching facility at Hyderabad jointly supported by TIFR and ISRO. This facility has been extensively used for carrying out research in high energy (i.e., X- and gamma ray) astronomy, IR astronomy, middle atmospheric trace constituents including CFCs & aerosols, ionisation, electric conductivity and electric fields.
The flux of secondary particles and X-ray and gamma-rays of atmospheric origin produced by the interaction of the cosmic rays is very low. This low background, in the presence of which one has to detect the feeble signal from cosmic sources is a major advantage in conducting hard X-ray observations from India. The second advantage is that many bright sources like Cyg X-1, Crab Nebula, Scorpius X-1 and Galactic Centre sources are observable from Hyderabad due to their favourable declination. With these considerations, an X-ray astronomy group was formed at TIFR in 1967 and development of an instrument with an orientable X-ray telescope for hard X-ray observations was undertaken. The first balloon flight with the new instrument was made on 28 April 1968 in which observations of Scorpius X-1 were successfully carried out. In a succession of balloon flights made with this instrument between 1968 and 1974 a number of binary X-ray sources including Scorpius X-1, Cyg X-1, Her X-1 etc. and the diffuse cosmic X-ray background were studied. Many new and astrophysically important results were obtained from these observations.
One of most important achievements of ISRO in this field was the discovery of three species of bacteria in the upper stratosphere at an altitude of between 20–40 km. The bacteria, highly resistant to ultra-violet radiation, are not found elsewhere on Earth, leading to speculation on whether they are extraterrestrial in origin. These three bacteria can be considered to be extremophiles. Until then, the upper stratosphere was believed to be inhospitable because of the high doses of ultra-violet radiation. The bacteria were named as Bacillus isronensis in recognition of ISRO's contribution in the balloon experiments, which led to its discovery, Bacillus aryabhata after India's celebrated ancient astronomer Aryabhata and Janibacter Hoylei after the distinguished astrophysicist Fred Hoyle.
ISRO's headquarters is located at Antariksh Bhavan in Bengaluru.

|This section requires expansion. (February 2014)|
The Indian Space Research Organisation launched its first Mars orbiter, called Mars Orbiter Mission, or Mangalyaan, on 5 November 2013. Mangalyaan carries a 15-kilogram suite of five science instruments to study the Martian upper atmosphere, surface features and mineralogy. It is India's first interplanetary mission and, if successful, ISRO would become the first Asian space agency to reach Mars. The spacecraft crossed its half-way mark on 9 April 2014.
ISRO plans to carry out a mission to the Sun by the year 2015-16. The probe is named as Aditya-1 and will weigh about 400 kg. It is the First Indian space based Solar Coronagraph to study solar Corona in visible and near IR bands. Launch of the Aditya mission was planned during the high solar activity period in 2012 but was postponed to 2015–2016 due to the extensive work involved in the fabrication and other technical aspects . The main objectives is to study the Coronal Mass Ejection (CME) and consequently the crucial physical parameters for space weather such as the coronal magnetic field structures, evolution of the coronal magnetic field etc. This will provide completely new information on the velocity fields and their variability in the inner corona having an important bearing on the unsolved problem of heating of the corona would be obtained.
Space Capsule Recovery Experiment II The main objective of SRE II is to realise a fully recoverable capsule and provide a platform to conduct microgravity experiments on Micro-biology, Agriculture, Powder Metallurgy, etc. SRE-2 is proposed to be launched on board PSLV.
India uses its satellites communication network – one of the largest in the world – for applications such as land management, water resources management, natural disaster forecasting, radio networking, weather forecasting, meteorological imaging and computer communication. Business, administrative services, and schemes such as the National Informatics Centre (NICNET) are direct beneficiaries of applied satellite technology. Dinshaw Mistry—on the subject of practical applications of the Indian space programme—writes:
The INSAT-2 satellites also provide telephone links to remote areas; data transmission for organisations such as the National Stock Exchange; mobile satellite service communications for private operators, railways, and road transport; and broadcast satellite services, used by India's state-owned television agency as well as commercial television channels. India's EDUSAT (Educational Satellite), launched aboard the GSLV in 2004, was intended for adult literacy and distance learning applications in rural areas. It augmented and would eventually replace such capabilities already provided by INSAT-3B.
The IRS satellites have found applications with the Indian Natural Resource Management programme, with regional Remote Sensing Service Centres in five Indian cities, and with Remote Sensing Application Centres in twenty Indian states that use IRS images for economic development applications. These include environmental monitoring, analysing soil erosion and the impact of soil conservation measures, forestry management, determining land cover for wildlife sanctuaries, delineating groundwater potential zones, flood inundation mapping, drought monitoring, estimating crop acreage and deriving agricultural production estimates, fisheries monitoring, mining and geological applications such as surveying metal and mineral deposits, and urban planning.
India's satellites and satellite launch vehicles have had military spin-offs. While India's 93–124-mile (150–250 km) range Prithvi missile is not derived from the Indian space programme, the intermediate range Agni missile is drawn from the Indian space programme's SLV-3. In its early years, when headed by Vikram Sarabhai and Satish Dhawan, ISRO opposed military applications for its dual-use projects such as the SLV-3. Eventually, however, the Defence Research and Development Organisation(DRDO)–based missile programme borrowed human resources and technology from ISRO. Missile scientist Dr APJ Abdul Kalam (elected president of India in 2002), who had headed the SLV-3 project at ISRO, moved to DRDO to direct India's missile programme. About a dozen scientists accompanied Kalam from ISRO to DRDO, where he designed the Agni missile using the SLV-3's solidfuel first stage and a liquid-fuel (Prithvi-missile-derived) second stage. The IRS and INSAT satellites were primarily intended and used for civilian-economic applications, but they also offered military spin-offs. In 1996 New Delhi's Ministry of Defence temporarily blocked the use of IRS-1C by India's environmental and agricultural ministries in order to monitor ballistic missiles near India's borders. In 1997 the Indian air force's "Airpower Doctrine" aspired to use space assets for surveillance and battle management.
Institutions like the Indira Gandhi National Open University (IGNOU) and the Indian Institute of Technology use satellites for scholarly applications. Between 1975 and 1976, India conducted its largest sociological programme using space technology, reaching 2400 villages through video programming in local languages aimed at educational development via ATS-6 technology developed by NASA. This experiment—named Satellite Instructional Television Experiment (SITE)—conducted large scale video broadcasts resulting in significant improvement in rural education.
ISRO has applied its technology to "telemedicine", directly connecting patients in rural areas to medical professionals in urban locations via satellites. Since high-quality healthcare is not universally available in some of the remote areas of India, the patients in remote areas are diagnosed and analysed by doctors in urban centres in real time via video conferencing. The patient is then advised medicine and treatment. The patient is then treated by the staff at one of the 'super-specialty hospitals' under instructions from the doctor. Mobile telemedicine vans are also deployed to visit locations in far-flung areas and provide diagnosis and support to patients.
ISRO has also helped implement India's Biodiversity Information System, completed in October 2002. Nirupa Sen details the programme: "Based on intensive field sampling and mapping using satellite remote sensing and geospatial modelling tools, maps have been made of vegetation cover on a 1 : 250,000 scale. This has been put together in a web-enabled database which links gene-level information of plant species with spatial information in a BIOSPEC database of the ecological hot spot regions, namely northeastern India, Western Ghats, Western Himalayas and Andaman and Nicobar Islands. This has been made possible with collaboration between the Department of Biotechnology and ISRO."
The Indian IRS-P5 (CARTOSAT-1) was equipped with high-resolution panchromatic equipment to enable it for cartographic purposes. IRS-P5 (CARTOSAT-1) was followed by a more advanced model named IRS-P6 developed also for agricultural applications. The CARTOSAT-2 project, equipped with single panchromatic camera which supported scene-specific on-spot images, succeed the CARTOSAT-1 project.
ISRO has had the benefit of International cooperation since inception.
ISRO and the Department of Space have signed formal Memorandum of Understanding agreements with a number of foreign political entities, including:-
India carries out joint operations with foreign space agencies, such as the Indo-French Megha-Tropiques Mission. On 25 June 2002 India and the European Union agreed to bilateral cooperation in the field of science and technology. A joint EU-India group of scholars was formed on 23 November 2001 to further promote joint research and development. India holds observer status at CERN while a joint India-EU Software Education and Development Centre is due at Bengaluru. In the 39th Scientific Assembly of Committee on Space Research held in Mysore, the Chairman of ISRO called upon international synergy in space missions in view of their prohibitive cost. He also disclosed that his organisation is grearing up to meet the growing demand of service providers, security agencies, etc. in a cost effective manner.
ISRO's current orange and blue logo was adopted in 2002. The blue boxes form solar arrays, providing energy to a satellite depicted by a part of the orange chevron. The chevron, pointing upwards, also signifies a launch vehicle - exploring the new heights of space.
The logo also renders two 'words' spelling "ISRO", on either side of the chevron: the English letters "ISRO", in the 'Prakrta' font (on the right), are balanced the transliterated depiction of the same 'word' in the Devanagari script.
The latest issue of 'Space India' (journal of the organisation) at the time of adoption, described the chevron as a visual representation of ISRO's upward mobility, symbolising the organisation's vanguard actions in breaking barriers both of gravity, and mindsets. It goes on to say that the vibrant, dynamic and energetic logo - full of vitality, depicts the in-space ambitions and aspirations of the organisation.
