SSLV Ascent
The Small Satellite Launch Vehicle (SSLV) is a small-lift launch vehicle developed by ISRO with payload capacity to deliver to low Earth orbit () or to Sun-synchronous orbit () for launching small satellites, with the capability to support multiple orbital drop-offs. SSLV is made keeping low cost, low turnaround time in mind with launch-on-demand flexibility under minimal infrastructure requirements. The maiden flight SSLV-D1 was conducted on 7 August 2022, from the Satish Dhawan FLP, First Launch Pad, but failed to reach a stable orbit. In the future, a dedicated launch site called Kulasekharapatnam Spaceport, SSLV Launch Complex (SLC) near Kulasekharapatnam in Tamil Nadu will handle SSLV launches to Sun-synchronous orbit. After entering the operational phase, the vehicle's production and launch operations will be done by a consortium of Indian firms along with NewSpace India Limited (NSIL). Vehicle description The SSLV was developed with the aim of launching small sate ... [...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 consists of medium-lift launch vehicles.50t payloads" 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. NASA 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 NASA orbital launch. The Vanguard I mission was the second successful NASA orbital launch. This was the start of the space race. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Static Fire Test
Launch vehicle system tests assess the readiness of a launch system to safely reach orbit. Launch vehicles undergo system tests before they launch. A wet dress rehearsal (WDR) and a more extensive static fire tests a fully assembled launch vehicle and its associated ground support equipment (GSE) prior to launch. The spacecraft/payload may or may not be attached to the launch vehicle during the WDR or static fire, but sufficient elements of the rocket and all relevant ground support equipment are in place to help verify that the rocket is ready for flight. Propellant load tests and static fire tests may also be done on prototype rocket stages as well, in which case no fully assembled launch vehicle is involved. Wet dress rehearsal A wet dress rehearsal is called "wet" because the liquid propellant components (such as liquid oxygen, liquid hydrogen, etc.) are loaded into the rocket during the test. In a pure wet dress rehearsal the rocket engines are not ignited. Wet dress rehear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Delta-v
Delta-''v'' (more known as "change in velocity"), symbolized as ∆''v'' and pronounced ''delta-vee'', as used in spacecraft flight dynamics, is a measure of the impulse per unit of spacecraft mass that is needed to perform a maneuver such as launching from or landing on a planet or moon, or an in-space orbital maneuver. It is a scalar that has the units of speed. As used in this context, it is not the same as the physical change in velocity of the vehicle. As a simple example, take a conventional rocket-propelled spacecraft which achieves thrust by burning fuel. The spacecraft's delta-''v'' is the change in velocity that spacecraft can achieve by burning its entire fuel load. Delta-''v'' is produced by reaction engines, such as rocket engines, and is proportional to the thrust per unit mass and the burn time. It is used to determine the mass of propellant required for the given maneuver through the Tsiolkovsky rocket equation. For multiple maneuvers, delta-''v'' sums l ...

Augmented Satellite Launch Vehicle
The Augmented Satellite Launch Vehicle or Advanced Satellite Launch Vehicle, also known as ASLV, was a small-lift launch vehicle five-stage solid-fuel rocket developed by the Indian Space Research Organisation (ISRO) to place 150 kg satellites into LEO. This project was started by India during the early 1980s to develop technologies needed for a payload to be placed into a geostationary orbit. Its design was based on Satellite Launch Vehicle. ISRO did not have sufficient funds for both the Polar Satellite Launch Vehicle programme and the ASLV programme at the same time and the ASLV programme was terminated after the initial developmental flights. The payloads of ASLV were Stretched Rohini Satellites. Vehicle The ASLV was a five-stage vehicle. Two strap-on boosters acted as a first stage, with the core stage igniting after booster burn out. The payload capacity of the ASLV was approximately to an orbit of with a 47-degree inclination. At liftoff, the ASLV generated of th ...

Satellite Launch Vehicle
The Satellite Launch Vehicle or SLV was a small-lift launch vehicle project started in the early 1970s by the Indian Space Research Organisation to develop the technology needed to launch satellites. SLV was intended to reach a height of and carry a payload of . The first experimental flight of SLV-3, in August 1979, was a failure. The first successful launch took place on 18 July 1980. It was a four-stage rocket with all solid-propellant motors. The first launch of the SLV took place in Sriharikota on 10 August 1979. The fourth and final launch of the SLV took place on 17 April 1983. It has taken approximately seven years to realise the vehicle from start. The solid motor case for first and second stage are fabricated from 15 CDV6 steel sheets and third and fourth stages from fibre reinforced plastic. Launch statistics Launch history All four SLV launches occurred from the SLV Launch Pad at the Sriharikota High Altitude Range. The first two launches were experimental ...

Geosynchronous Satellite Launch Vehicle
Geosynchronous Satellite Launch Vehicle (GSLV) is an expendable launch system operated by the Indian Space Research Organisation (ISRO). GSLV was used in fourteen launches from 2001 to 2021. Even though GSLV Mark III shares the name, it is an entirely different launch vehicle. History The Geosynchronous Satellite Launch Vehicle (GSLV) project was initiated in 1990 with the objective of acquiring an Indian launch capability for geosynchronous satellites. GSLV uses major components that are already proven in the Polar Satellite Launch Vehicle (PSLV) launch vehicles in the form of the S125/S139 solid rocket booster and the liquid-fueled Vikas engine. Due to the thrust required for injecting the satellite in a geostationary transfer orbit (GTO) the third stage was to be powered by a LOX/LH2 Cryogenic engine which at that time India did not possess or have the technological expertise to build. The first development flight of the GSLV (Mk I configuration) was launched on 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polar Satellite Launch Vehicle
The Polar Satellite Launch Vehicle (PSLV) is an expendable medium-lift launch vehicle designed and operated by the Indian Space Research Organisation (ISRO). It was developed to allow India to launch its Indian Remote Sensing (IRS) satellites into sun-synchronous orbits, a service that was, until the advent of the PSLV in 1993, only commercially available from Russia. PSLV can also launch small size satellites into Geostationary Transfer Orbit (GTO). Some notable payloads launched by PSLV include India's first lunar probe Chandrayaan-1, India's first interplanetary mission, Mars Orbiter Mission (Mangalyaan) and India's first space observatory, Astrosat. PSLV has gained credibility as a leading provider of rideshare services for small satellites, owing to its numerous multi-satellite deployment campaigns with auxiliary payloads, usually ride-sharing along with an Indian primary payload. As of June 2022, PSLV has launched 345 foreign satellites from 36 countries. Most notable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
