RLV Technology Demonstration Programme
Reusable Launch Vehicle–Technology Demonstration Programme is a series of technology demonstration missions that has been conceived by the Indian Space Research Organisation (ISRO) as a first step towards realising a Two Stage To Orbit (TSTO) re-usable launch vehicle. For this purpose, a winged reusable launch vehicle technology demonstrator ( RLV-TD) has been configured. The RLV-TD acted as a flying test bed to evaluate various technologies like powered cruise flight, hypersonic flight, and autonomous landing using air-breathing propulsion. Application of these technologies would bring down the launch cost by a factor of 10. This project has no connection with the Avatar spaceplane concept by India's Defence Research and Development Organisation. Development In 2006 the Indian Space Research Organisation performed a series of ground tests to demonstrate stable supersonic combustion for nearly 7 seconds with an inlet Mach number of 6. In March 2010, ISRO conducted the flig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vikram Sarabhai Space Centre
The Vikram Sarabhai Space Centre (VSSC) is a major space research centre of the Indian Space Research Organisation (ISRO), focusing on rocket and space vehicles for India's satellite programme. It is located in Thiruvananthapuram, in the Indian state of Kerala. The centre had its beginnings as the Thumba Equatorial Rocket Launching Station (TERLS) in 1962. It was renamed in honour of Dr. Vikram Sarabhai, often regarded as the father of the Indian space program. H.G.S. Murthy was appointed as the first director of Thumba Equatorial Rocket Launching Station. The Vikram Sarabhai Space Centre is one of the main research and development establishments within ISRO. VSSC is an entirely indigenous facility working on the development of sounding rockets, the Rohini and Menaka launchers, and SLV, ASLV, PSLV, GSLV and GSLV Mk III families of launch vehicles. History The space centre is the largest among the ISRO facilities. It is a centre for the design and development of satellit ...

It was formed in 1958 by the merger of the Technical Development Establishment and the Directorate of Technical Development and Production of the Indian Ordnance Factories with the Defence Science Organisation. Subsequently, Defence Research & Development Service (DRDS) was constituted in 1979 as a service of Group 'A' Officers / Scientists directly under the administrative control of Ministry of Defence. With a network of 52 laboratories that are engaged in developing defence technologies covering various fields like aeronautics, armaments, electronics, land combat engineering, life sciences, materials, missiles, and naval systems, DRDO is India's large ...

Splashdown
Splashdown is the method of landing a spacecraft by parachute in a body of water. It was used by crewed American space capsules prior to the Space Shuttle program, by SpaceX Dragon and Dragon 2 capsules and by NASA's Orion Multipurpose Crew Vehicle. It is also possible for the Russian Soyuz spacecraft to land in water, though this is only a contingency. The only example of an unintentional crewed splashdown in Soviet history is the Soyuz 23 landing. As the name suggests, the capsule parachutes into an ocean or other large body of water. The properties of water cushion the spacecraft enough that there is no need for a braking rocket to slow the final descent as is the case with Russian and Chinese crewed space capsules (while Shenzhou designed a raft and balanced capsule in case of splashdown), which return to Earth over land. The American practice came in part because American launch sites are on the coastline and launch primarily over water. Russian launch sites are far ...

Bay Of Bengal
The Bay of Bengal is the northeastern part of the Indian Ocean, bounded on the west and northwest by India, on the north by Bangladesh, and on the east by Myanmar and the Andaman and Nicobar Islands of India. Its southern limit is a line between Sangaman Kanda, Sri Lanka, and the north westernmost point of Sumatra, Indonesia. It is the largest water region called a bay in the world. There are countries dependent on the Bay of Bengal in South Asia and Southeast Asia. During the existence of British India, it was named as the Bay of Bengal after the historic Bengal region. At the time, the Port of Kolkata served as the gateway to the Crown rule in India. Cox's Bazar, the longest sea beach in the world and Sundarbans, the largest mangrove forest and the natural habitat of the Bengal tiger, are located along the bay. The Bay of Bengal occupies an area of . A number of large rivers flow into the Bay of Bengal: the Ganges– Hooghly, the Padma, the Brahmaputra–Yamuna, the B ...

Atmospheric Entry
Atmospheric entry is the movement of an object from outer space into and through the gases of an atmosphere of a planet, dwarf planet, or natural satellite. There are two main types of atmospheric entry: ''uncontrolled entry'', such as the entry of astronomical objects, space debris, or bolides; and ''controlled entry'' (or ''reentry'') of a spacecraft capable of being navigated or following a predetermined course. Technologies and procedures allowing the controlled atmospheric ''entry, descent, and landing'' of spacecraft are collectively termed as ''EDL''. Objects entering an atmosphere experience atmospheric drag, which puts mechanical stress on the object, and aerodynamic heating—caused mostly by compression of the air in front of the object, but also by drag. These forces can cause loss of mass (ablation) or even complete disintegration of smaller objects, and objects with lower compressive strength can explode. Crewed space vehicles must be slowed to subsonic spee ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thumba Equatorial Rocket Launching Station
Thumba Equatorial Rocket Launching Station (TERLS) is an Indian spaceport established on 21 November 1963. Operated by the Indian Space Research Organisation (ISRO), it is located in Thumba, Thiruvananthapuram, Kerala, which is near the southern tip of mainland India, very close to earth's magnetic equator. It is currently used by ISRO for launching sounding rockets. The first rockets were assembled in former St Louis High School, which houses now a space museum. The local Bishop, Rev. Peter Bernard Periera, Bishop of Trivandrum, Vincent Victor Dereere (a Belgian) and district collector Madhavan Nair were instrumental in acquiring a large parcel of land measuring 600 acres from coastal community. The Bishop Rev. Periera had given away the prayer hall and bishop's room in the local church for scientific pursuits of A. P. J. Abdul Kalam. Then Minister of State for External Affairs, Lakshmi N. Menon helped a lot in smoothing the bureaucratic hurdles before the project at Delhi. H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
