Vikram (rocket Family)
The Vikram (Sanskrit, ; Namesake: Vikram Sarabhai) is a family of small-lift launch vehicles being developed by Skyroot Aerospace, an Indian startup aerospace company. Before a full orbital launch, a suborbital flight of rocket designated Vikram-S was performed on 18 November 2022 by the name of mission ''Prarambh'' (Sanskrit, ). Overview Skyroot Aerospace has successfully tested Vikram-S, the sounding rocket. Vikram-I is currently under development while the heavier launchers of Vikram-II and Vikram-III are proposed. Vikram-I The Vikram-I, first rocket in the series, has three solid fuel-powered stages each with a burn time ranging between 80 and 100 seconds and the final stage is Raman engine (Sanskrit, , Namesake: C.V. Raman). The Raman engine is powered by MMH and NTO liquid fuels in a cluster of four engines that generate 3.4 kN thrust. These Raman Engines will be used to do final adjustments in the orbit of the stage. Vikram-I is designed to lift 290 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Small-lift Launch Vehicle
A small-lift launch vehicle is a rocket orbital launch vehicle that is capable of lifting or less (by NASA classification) or under (by Roscosmos classification) of payload into low Earth orbit (LEO). The next larger category is medium-lift launch vehicles. The first small-lift launch vehicle was the Sputnik rocket, launched by the Soviet Union, which was derived from the R-7 Semyorka ICBM. On 4 October 1957, the Sputnik rocket was used to perform the world's first satellite launch, placing the Sputnik 1 satellite into a low Earth orbit. The US responded by attempting to launch the Vanguard rocket. However, the Vanguard TV3 launch attempt failed, with the 31 January 1958 launch of the Explorer 1 satellite using the Juno I rocket being the first successful US orbital launch. The Vanguard I mission was the second successful US orbital launch. This was the start of the space race. Since the late 1950s, small-lift launch vehicles have continued launching payloads into orbits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dinitrogen Tetroxide
Dinitrogen tetroxide, commonly referred to as nitrogen tetroxide (NTO), and occasionally (usually among ex-USSR/Russian rocket engineers) as amyl, is the chemical compound N2O4. It is a useful reagent in chemical synthesis. It forms an equilibrium mixture with nitrogen dioxide. Its molar mass is 92.011 g/mol. Dinitrogen tetroxide is a powerful oxidizer that is hypergolic (spontaneously reacts) upon contact with various forms of hydrazine, which has made the pair a common bipropellant for rockets. Structure and properties Dinitrogen tetroxide could be regarded as two nitro groups (-NO2) bonded together. It forms an equilibrium mixture with nitrogen dioxide. The molecule is planar with an N-N bond distance of 1.78Å and N-O distances of 1.19Å. The N-N distance corresponds to a weak bond, since it is significantly longer than the average N-N single bond length of 1.45Å. This exceptionally weak σ bond (amounting to overlapping of the ''sp''2 hybrid orbitals of the two NO2 uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liquid Propulsion Systems Centre
The Liquid Propulsion Systems Centre (LPSC) is a research and development centre functioning under the Indian Space Research Organisation (ISRO). It has two units located at Valiamala, in Thiruvananthapuram, Kerala, and Bengaluru, Karnataka. LPSC is augmented by ISRO Propulsion Complex at Mahendragiri of Tamil Nadu. LPSC is engaged in development of liquid and cryogenic propulsion stages for launch vehicles and auxiliary propulsion systems for both launch vehicles and satellites.

IN-SPACe
Indian National Space Promotion and Authorisation Centre (IN–SPACe) is a single-window autonomous agency under the Department of Space of the Government of India. The establishment of IN–SPACe was announced in June 2020 by the Minister of State for Space Jitendra Singh, with the Union Cabinet approving its creation. In the same month Secretary (Space) and chairperson of the Indian Space Research Organisation, K. Sivan, said that it would take up to sixmonths to operationalize IN–SPACe, with the Department of Space handling its functions in the meantime. History Space programme in India has been developed over a period of more than five decades with a strong focus on application driven programmes and bringing space to the services of the common man. In the process, it has become one of the six largest space agencies in the world. The Indian Space Research Organisation (ISRO) maintains one of the largest fleets of GEO communication and LEO remote sensing satellites, th ...

ISRO
The Indian Space Research Organisation (ISRO ) is India's national space agency, headquartered in Bengaluru, Karnataka. It serves as the principal research and development arm of the Department of Space (DoS), overseen by the Prime Minister of India, with the Chairman of ISRO also serving as the chief executive of the DoS. It is primarily responsible for space-based operations, space exploration, international space cooperation and the development of related technologies. The agency maintains a constellation of imaging, communications and remote sensing satellites. It operates the GAGAN and IRNSS satellite navigation systems. It has sent three missions to the Moon and one mission to Mars. Formerly known as the Indian National Committee for Space Research (INCOSPAR), ISRO was set up in 1962 by the Government of India on the recommendation of scientist Vikram Sarabhai. It was renamed as ISRO in 1969 and was subsumed into the Department of Atomic Energy (DAE). The establi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vikram-S Rocket's Mission Prarambh 01
Vikram-S is India's first privately built rocket. Its maiden flight lifted on 18 November 2022 at 11 A.M. from Sounding Rocket Complex, Sriharikota. The rocket was designed and developed by Skyroot Aerospace. History Vikram-S, India's first privately built rocket was launched on 18 November 2022 by Skyroot Aerospace from Sriharikota. The first mission of the rocket launch has been designated as 'Prarambh', meaning beginning.

Rocket Scientist
A rocket (from , and so named for its shape) is a vehicle that uses jet propulsion to accelerate without using any surrounding air. A rocket engine produces thrust by reaction to exhaust expelled at high speed. Rocket engines work entirely from propellant carried within the vehicle; therefore a rocket can fly in the vacuum of space. Rockets work more efficiently in a vacuum and incur a loss of thrust due to the opposing pressure of the atmosphere. Multistage rockets are capable of attaining escape velocity from Earth and therefore can achieve unlimited maximum altitude. Compared with airbreathing engines, rockets are lightweight and powerful and capable of generating large accelerations. To control their flight, rockets rely on momentum, airfoils, auxiliary reaction engines, gimballed thrust, momentum wheels, deflection of the exhaust stream, propellant flow, spin, or gravity. Rockets for military and recreational uses date back to at least 13th-century China. Sign ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
