Space Research – India

SPACE COMMISSION

The Indian Space programme began with the setting up of a sounding rocket launching facility at Thumba, near Thiruvanthapuram in 1963. The Thumba Equatorial Rocket Launching Station (TERLS) served as the nucleus for the growth of Indian Space Research Organisation (ISRO). In 1972 the Department of Space (DOS) was established with its headquarters at Bangalore. DOS is responsible for the execution of India’s space activities through ISRO. ISRO today encompasses the following centres:

(1) Vikram Sarabhai Space Centre (VSSC), Thumba near Thiruvanthapuram (Kerala); (2) Sriharikota Range (SHAR) in Andhra Pradesh; (3) Space Application Centre at Thumba; (4) Physical Research Laboratory, Ahmedabad (Gujarat); (5) ISRO, Satellite Centre (ISAC), Bangalore; (6) Auxiliary Propulsion System Unit (APSU), Bangalore; (7) ISRO Telemetry, Tracking & Command Network (ISTRAC) with its headquarters at Bangalore; and (8) National Remote Sensing Agency (NRSA), Hyderabad.

INDIAN SPACE PROGRAMME

It was on 21 November 1963, that the first two-stage imported rocket zoomed into space from Thumba, near Thiruvanthapuram. This heralded the modern era of space research and applications in the country. The space programme has since graduated from sounding rockets and passive vapour cloud payloads to the developments of guidance-controlled satellite launch vehicles and state-of-the-art satellite systems.

The programme has achieved a high degree of self-reliance in space technology, including the use of space technology for practical applications of relevance to the country.

During past years, the space programme has had a large number of successes and a few setbacks especially in the developmental plans on hitech areas. But the failures notwithstanding, the country has benefited from the operational systems.

In particular, progress has been made in the Satellite Telecommunication Experiment Projects (STEP), the Ariane Passenger Payload Experiment (APPLE), the Satellite for Earth Observations (SEO), the Indian National Satellite (INSAT) programme and remote sensing (IRS). The INSAT system represents a practical application of the space technology to socio-economic purposes.

The launching of IRS-1A satellite marked a major breakthrough in the country’s efforts to utilise remote-sensing techniques for continuous monitoring of natural resources.

India launched itself into a major space power with the successful placing of 870-kg satellite, IRS-P2, using the Polar Satellite Launch Vehicle. The PSLV-D2 launch enabled India to join the select band of countries that have the capacity of hurling into space 1000 kg satellites.

On 31 August, the launch of IRSO’s eight navigation satellite IRNSS-1H, on-board PSLV-C39,  was unsuccessful. The heat shield did not separate, as a result of which the fourth stage of the launch failed.

FIRST INDIAN IN SPACE

April 3, 1984, was a historic day for India when the country achieved yet another distinction in space—Squadron Leader Rakesh Sharma, test pilot of the IAF, became the first Indian to soar into space. Sqn Ldr Rakesh Sharma was the world’s 138th cosmonaut and the 11th to fly with Soviet cosmonauts in the inter-cosmos programme. India was the 14th nation to have sent its citizen into space.

INDIA’S MISSION TO MOON

On 22 October 2008, PSLV-CII launched India’s first unmanned lunar mission, Chandrayaan-I, which entered the lunar orbit on 7 November 2008. India thus became the fifth country in the world to send a spacecraft to moon.

On 14 November 2008, the Moon Impact Probe (MIP), named Aditya ejected from Chandrayaan-I, successfully touched down on moon surface, thus planting India’s flag on the moon.

Five minutes before midnight on 20 August 2009, India’s Moon mission, Chandrayaan-1, crossed an important milestone when it teamed up with NASA’s Lunar Reconnaissance Orbiter in search of water ice.

Both the spacecraft moved simultaneously picking up data. The historic combined flight was tracked by ISRO’s deep space network at Byalalu, Bangalore and NASA’s deep space network and Applied Physics Laboratory in Maryland, US.

Both spacecraft were equipped with radar instruments—Mini-Sar (Synthetic Aperture Radar) on Chandrayaan-1 and Mini-Rf on LRO. The two instruments targeted the same spot on the Moon from different angles, with Chandrayaan-1’s radar transmitting a signal which was reflected off interior of Erlanger Crater. This was picked up by LRO.

On 30 August 2009, the mission had to be called off, much ahead of its scheduled life, due to snapping of radio link.

INDIA’S MISSION TO MARS

On 24 September 2014, India created history, becoming the first country in the world to succeed on its first Mars mission as ISRO’s Mangalyaan successfully slipped into Martian orbit after a few nail-biting moments. The spacecraft had blasted off from Sriharikota on 5 November 2013

India is also the first Asian country to send successfully send a spacecraft to Mars. The country joined the United States, European Space Agency and the former Soviet Union in the elite club of Martian explorers with the Mars Orbiter Mission, affectionately called MOM.

India’s feat gained significance in the light of the fact that more than half the world’s previous attempts—23 out of 41 Mars missions—failed, including attempts by Japan in 1999 and China in 2011.

MOM’s scientific goals included using of five solar-powered instruments to gather data that will help determine how Martian weather systems work and what happened to the water that is believed to have once existed on Mars in large quantities. Mangalyaan also searched Mars for methane, a key chemical in life processes on Earth that could also come from geological processes.
