Rohini (satellite)

Rohini is a series of satellites launched by the Indian Space Research Organisation (ISRO). The Rohini series consisted of four satellites, each of which was launched by the Satellite Launch Vehicle (SLV)[1] and three of which made it successfully to orbit. The series were mostly experimental satellites.

Satellites in series

Rohini Technology Payload (RTP)

It was a 35 kg (77 lb) experimental spin stabilized satellite that used 3W of power and was launched on 10 August 1979 from SDSC.[2] The satellite contained instruments to monitor the launch vehicle. It did not achieve its intended orbit as the carrier rocket SLV was only 'partially successful'.

RS-1

It was also a 35 kg (77 lb) experimental spin stabilized satellite that used 16W of power and was successfully launched on 18 July 1980 from Satish Dhawan Space Centre[3] into an orbit of 305 km × 919 km (190 mi × 571 mi) with an inclination of 44.7°. It was the first satellite successfully launched by the indigenous launch vehicle SLV. It provided data on the fourth stage of SLV. The satellite had mission life of 1.2 years and an orbital life of 20 months.

RS-D1

It was a 38 kg (84 lb) experimental spin stabilized satellite that used 16W of power and was launched on 31 May 1981.[4] The launch of the SLV was a partial success as the satellite did not reach the intended height and thus it only stayed in orbit for 9 days. It achieved an orbit of 186 km × 418 km (116 mi × 260 mi) with an inclination of 46°. The satellite carried a solid state camera for remote sensing applications (Landmark Tracker) and performed to specifications.

RS-D2

It was a 41.5 kg (91 lb) experimental spin stabilized satellite that used 16W of power and was launched successfully on 17 April 1983[5] into an orbit of 371 km × 861 km (231 mi × 535 mi) and an inclination of 46°. The satellite was in operation (mission life) for 17 months and its main payload, a smart sensor camera, took over 2500 pictures. The camera had the capability to take pictures both in visible and infrared bands. After an orbital life of 7 years, the satellite reentered the Earth atmosphere on 19 April 1990.

A. P. J. Abdul Kalam

Avul Pakir Jainulabdeen Abdul Kalam ( (listen); 15 October 1931 – 27 July 2015) was an aerospace scientist who served as the 11th President of India from 2002 to 2007. He was born and raised in Rameswaram, Tamil Nadu and studied physics and aerospace engineering. He spent the next four decades as a scientist and science administrator, mainly at the Defence Research and Development Organisation (DRDO) and Indian Space Research Organisation (ISRO) and was intimately involved in India's civilian space programme and military missile development efforts. He thus came to be known as the Missile Man of India for his work on the development of ballistic missile and launch vehicle technology. He also played a pivotal organisational, technical, and political role in India's Pokhran-II nuclear tests in 1998, the first since the original nuclear test by India in 1974.Kalam was elected as the 11th President of India in 2002 with the support of both the ruling Bharatiya Janata Party and the then-opposition Indian National Congress. Widely referred to as the "People's President", he returned to his civilian life of education, writing and public service after a single term. He was a recipient of several prestigious awards, including the Bharat Ratna, India's highest civilian honour.

While delivering a lecture at the Indian Institute of Management Shillong, Kalam collapsed and died from an apparent cardiac arrest on 27 July 2015, aged 83. Thousands including national-level dignitaries attended the funeral ceremony held in his hometown of Rameshwaram, where he was buried with full state honours.

List of Indian satellites

India has been successfully launching satellites of many types since 1975. These satellites have been launched from various vehicles, including American, Russian and European rockets apart from Indian rockets. The organisation responsible for India's space program is Indian Space Research Organisation (ISRO) and it shoulders the bulk of the responsibility of designing, building, launching and operating these satellites.

List of Satish Dhawan Space Centre launches

The following list gives a detailed record of the launches taken place in Satish Dhawan Space Centre. It is the main satellite launch centre for the Indian Space Research Organisation (ISRO). It is located in Sriharikota, Andhra Pradesh, 80 km (50 mi) north of Chennai. Originally called Sriharikota Range (SHAR), an acronym that ISRO has retained to the present day. The centre was renamed in 2002 after the death of ISRO's former chairman Satish Dhawan.

Nilamber Pant

Nilamber Pant is an Indian space scientist, a former member of the Space Commission of India and a pioneer of satellite based communication and broadcasting in India. He served at the Satish Dhawan Space Centre and the ISRO Satellite Centre before becoming the vice chairman of the Indian Space Research Organization (ISRO). The Government of India awarded him the fourth highest Indian civilian honour of Padma Shri in 1984.

He was an elected Fellow of the Aeronautical Society of India and the Indian National Academy of Engineering. The Government of India awarded him the third highest civilian honour of the Padma Bhushan, in 2000, for his contributions to Indian space program.

Space and Upper Atmosphere Research Commission

The Space and Upper Atmosphere Research Commission (SUPARCO) is an executive and national space agency of the Government of Pakistan and a bilateral organisation of China National Space Administration, responsible for the nation's public and civil space programme and for aeronautics and aerospace research. Its mission statement and objective is to conduct research in space technology and promote the technology for socio-economic uplift of the country. The organisation, however, suffers from minute budget amount and lack of indigenous programmes.

Established in its modern form on 16 September 1961 by an executive order of President of Pakistan, it is headquartered in Karachi, Sindh Province of Pakistan. Part of the Strategic Plans Division (SPD) of Pakistan Armed Forces, which is currently headquartered at the Chakalala Military District under the control of the PAF; the space programmes recorded number of pioneering accomplishments in space flight during the initial years of its establishment.The country's first satellite, Badr-I, was built by the joint efforts of SUPARCO and CNSA and launched by the People's Republic of China in 1990. However, during the meantime, the space programme suffered many setbacks, difficulties, and problems that partly slowed the progress of the space programme. The bureaucratic influence and politicization further lagged the space programme and many projects were cancelled by the superior authorities.Over the years, SUPARCO expanded and it now has several installations all over the country. It has multi-lateral and bilateral international agreements. SUPARCO has been quite dormant in recent years and also have failed to make any breakthroughs.

SUPARCO's science and research is mainly focused and concentrated on understanding of the Solar system, Space weather, astrophysics, astronomical observation, climatic studies, space and telemedicine, remote sensing and the Earth observation.

Stretched Rohini Satellite Series

The Stretched Rohini Satellite Series (SROSS) are a series of satellites developed by the Indian Space Research Organisation as follow ons to the Rohini Satellites for conducting astrophysics, Earth Remote Sensing, and upper atmospheric monitoring experiments as well as for new and novel application-oriented missions. These satellites were the payload of the developmental flights of the Augmented Satellite Launch Vehicle.
