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 (ISRO) 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, 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 took approximately seven years to realise the vehicle from start. The solid motor case for first and second stage were fabricated from 15 CDV6 steel sheets and third and fourth stages from fibre reinforced plastic. The aerodynamic characterization research was conducted at the National Aerospace Laboratories' 1.2m Trisonic Wind Tunnel Facility. Launch history All four SLV launches occ ...

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] |

Low Earth Orbit
A low Earth orbit (LEO) is an geocentric orbit, orbit around Earth with a orbital period, period of 128 minutes or less (making at least 11.25 orbits per day) and an orbital eccentricity, eccentricity less than 0.25. Most of the artificial objects in outer space are in LEO, peaking in number at an altitude around , while the farthest in LEO, before medium Earth orbit (MEO), have an altitude of 2,000 km, about one-third of the Earth radius, radius of Earth and near the beginning of the Van Allen radiation belt#Inner belt, inner Van Allen radiation belt. The term ''LEO region'' is used for the area of space below an altitude of (about one-third of Earth's radius). Objects in orbits that pass through this zone, even if they have an apogee further out or are sub-orbital spaceflight, sub-orbital, are carefully tracked since they present a collision risk to the many LEO satellites. No human spaceflights other than the lunar missions of the Apollo program (1968-1972) have gone beyond L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Coordinated Universal Time
Coordinated Universal Time (UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and is the effective successor to Greenwich Mean Time (GMT) in everyday usage and common applications. In specialised domains such as scientific research, navigation, and timekeeping, other standards such as Universal Time, UT1 and International Atomic Time (TAI) are also used alongside UTC. UTC is based on TAI (International Atomic Time, abbreviated from its French name, ''temps atomique international''), which is a weighted average of hundreds of atomic clocks worldwide. UTC is within about one second of mean solar time at 0° longitude, the currently used prime meridian, and is not adjusted for daylight saving time. The coordination of t ...
