                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 400 kilometres (250 mi) and carry a payload of 40 kg (88 lb). 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.            </p>

                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.

            <p class="technology-p">
                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.

                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 150 kg (330 lb) to an orbit of 400 km (250 mi) with a 47-degree inclination. <br> <br>
                At liftoff, the ASLV generated 909.9 kN (204,500 lbf) of thrust. It was a 41,000-kilogram (90,000 lb) rocket, measuring 23.5 metres (77 ft) in length with a core diameter of one metre (3 ft 3 in). The height to diameter ratio of ASLV was very large which resulted in the vehicle being unstable in flight. This was compounded by the fact that many of the critical events during a launch like the core ignition and the booster separation happened at the Tropopause where the dynamic loads on the launcher was at the maximum.

                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, commercially available only 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. <br> <br>
                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 February 2021, PSLV has launched 342 foreign satellites from 36 countries. Most notable among these was the launch of PSLV-C37 on 15 February 2017, successfully deploying 104 satellites in sun-synchronous orbit, tripling the previous record held by Russia for the highest number of satellites sent to space on a single launch, until 24 January 2021, when SpaceX launched the Transporter-1 mission on a Falcon 9 rocket carrying 143 satellites into orbit. <br> <br>
                Payloads can be integrated in tandem configuration employing a Dual Launch Adapter. Smaller payloads are also placed on equipment deck and customized payload adapters.

In June 2018, the Union Cabinet approved ₹43.38 billion (US$580 million) to build 10 GSLV Mk III rockets over a five-year period. <br> <br>
                GSLV Mk III launched CARE, India's space capsule recovery experiment module, Chandrayaan-2, India's second lunar mission and will be used to carry Gaganyaan, the first crewed mission under Indian Human Spaceflight Programme.
