The Centre pursues active research and development in the fields of aeronautics, avionics, materials, mechanisms, vehicle integration, chemicals, propulsion, space ordnance, structures, space physics and systems reliability. The Centre undertakes crucial responsibilities of design, manufacturing, analysis, development and testing related to the realisation of subsystems for the different missions.

2 Genesis The space research activities were initiated in our country during the early 1960 s, when applications using satellites were in experimental stages even in the United States. Dr. Vikram Sarabhai, the founding father of Indian space programme, quickly recognized the benefits of space technologies for India. Dr. Sarabhai was convinced and envisioned that the resources in space have the potential to address the real problems of man and society. As Director, Physical Research Laboratory (PRL) located in Ahmedabad, Dr. Sarabhai convened an army of able and brilliant scientists, anthropologists, communicators and social scientists from all corners of the country to spearhead the Indian space programme. The INCOSPAR (Indian National Committee for Space Research) was initiated under the leadership of Dr. Sarabhai and Dr. Ramanathan. In 1967, the first Experimental Satellite Communication Earth Station (ESCES) located in Ahmedabad was operationalized, which also doubled as a training centre for the Indian as well as International scientists and engineers. During this period, the first Indian spacecraft Aryabhata was developed and was launched using a Soviet Launcher. Another major landmark was the development of the first launch vehicle SLV-3 with a capability to place 40 kg in Low Earth Orbit (LEO), which had its first successful flight in 1980

3 LAUNCHERS Launchers or Launch Vehicles are used to carry spacecraft to space. India has two operational launchers: Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV). GSLV with indigenous Cryogenic Upper Stage has enabled the launching up to 2 tonne class of communication satellites. The next variant of GSLV is GSLV Mk III, with indigenous high thrust cryogenic engine and stage, having the capability of launching 4 tonne class of communication satellites. In order to achieve high accuracy in placing satellites into their orbits, a combination of accuracy, efficiency, power and immaculate planning are required. ISRO's Launch Vehicle Programme spans numerous centres and employs over 5,000 people. Vikram Sarabhai Space Centre, located in Thiruvananthapuram, is responsible for the design and development of launch vehicles. Liquid Propulsion Systems Centre and ISRO Propulsion Complex, located at Valiamala and Mahendragiri respectively, develop the liquid and cryogenic stages for these launch vehicles.

4 APPLICATIONS Earth Observation The Indian Remote sensing programme is driven by the user needs. This pilot project led the development of Indian Remote Sensing (IRS) satellites. These IRS satellites have been the workhorse for several applications - encompassing the various sectors such as agriculture, land and water resources, forestry, environment, natural disasters.

5 Satellite Communication The communication satellite series, which started with the APPLE satellite, grew into a very large constellation of satellites in the INSAT and GSAT series. Indian Space Research Organisation (ISRO) has made remarkable progress towards building the space infrastructure - as the community resource to leapfrog the developmental processes. The launch of INSAT system has been the major catalyst in the rapid expansion of television coverage in India apart from growing applications like DTH, Satellite News Gathering, VSATs, Internet services etc. Use of INSAT for e-governance and developmental communication applications is also fast expanding. ;

6 Disaster Management Support Disaster management support, in terms of space based critical infrastructure and services, is yet another community centric deliverable. One of the elements on which the space based Disaster Management Support (DMS) systems have been built is emergency communications systems. The DMS programme of ISRO/DOS, a convergence of space communications and remote sensing capabilities, is an effort to have technologically robust and a compatible system, which could strengthen India s resolves towards disaster management. Satellite Navigation Satellite Navigation service is an emerging satellite based system with commercial and strategic applications. To meet the Civil Aviation requirements, ISRO is working jointly with Airport Authority of India (AAI) in establishing the GPS Aided Geo Augmented Navigation (GAGAN) system. To meet the user requirements of the positioning, navigation and timing services based on the indigenous system, ISRO is establishing a regional satellite navigation system called Indian Regional Navigation Satellite System (IRNSS).

7 Climate and Environment LATEST MISSION PSLV-C37 / Cartosat -2 Series Satellite India's Polar Satellite Launch Vehicle, in its thirty ninth flight (PSLV-C37), launches the 714 kg Cartosat-2 series satellite for earth observation and 103 co-passenger satellites together weighing about 663 kg at lift-off into a 505 km polar Sun Synchronous Orbit (SSO). PSLV-C37 was launched from the First Launch Pad (FLP) of Satish Dhawan Space Centre (SDSC) SHAR, Sriharikota. This was the sixteenth flight of PSLV in 'XL' configuration (with the use of solid strap-on motors). The co-passenger satellites comprised of 101 nano satellites, one each from Kazakhstan, Israel, The Netherlands, Switzerland, United Arab Emirates (UAE) and 96 from United States of America (USA), as well as two Nano satellites from India. The total weight of all these satellites carried on-board PSLV-C37 was about 1377 kg. PSLV-C37 also carried two ISRO Nano satellites (INS-1A and INS-1B), as co-passenger satellites. These two satellites carry a total of four different payloads from Space Applications Centre (SAC) and Laboratory for Electro Optics Systems (LEOS) of ISRO for conducting various experiments.

8 The 101 International customer Nano satellites were launched as part of the commercial arrangements between Antrix Corporation Limited (Antrix), a Government of India company under Department of Space (DOS), the commercial arm of ISRO and the International customers.

10 TRENDING MARS ORBITER MISSION The journey of Mars Orbiter from launch to Martian orbit: A look at the mission profile Marking India's first venture into the interplanetary space, MOM will explore and observe Mars surface features, morphology, mineralogy and the Martian atmosphere. Further, a specific search for methane in the Martian atmosphere will provide information about the possibility or the past existence of life on the planet. The enormous distances involved in interplanetary missions present a demanding challenge; developing and mastering the technologies essential for these missions will open endless possibilities for space exploration. After leaving Earth, the Orbiter will have to endure the Interplanetary space for 300 days before Mars capture. Apart from deep space communications and navigation-guidance-control capabilities, the mission will require autonomy at the spacecraft end to handle contingencies.

11 Once India decided to go to Mars, ISRO had no time to lose as the nearest launch window was only a few months away and it could not afford to lose the chance, given the next launch would present itself after over 780 days, in Thus, mission planning, manufacturing the spacecraft and the launch vehicle and readying the support systems took place swiftly.
