List Of Ariane Launches (1979–1989)
This is a list of List of Ariane launches, launches performed by Ariane (rocket family), Ariane carrier rockets between 1979, when the type first flew, and 1989. This period includes all flights of the Ariane 1, Ariane 2 and Ariane 3, as well as early Ariane 4 launches.

List Of Ariane Launches
Rockets from the Ariane (rocket family), Ariane rocket family have accumulated 258 launches since 1979, 246 of which were successful, yielding a success rate. The currently operational version, Ariane 5, has flown 82 consecutive missions without failure between April 2003 and December 2017, but suffered a malfunction during Ariane flight VA241, flight VA-241 in January 2018, causing its two satellites to reach an incorrect orbit, and reducing their predicted lifetime as they consumed some of their own fuel to raise their orbits.

Apple (satellite)
An apple is an edible fruit produced by an apple tree (''Malus domestica''). Apple trees are cultivated worldwide and are the most widely grown species in the genus ''Malus''. The tree originated in Central Asia, where its wild ancestor, '' Malus sieversii'', is still found today. Apples have been grown for thousands of years in Asia and Europe and were brought to North America by European colonists. Apples have religious and mythological significance in many cultures, including Norse, Greek, and European Christian tradition. Apples grown from seed tend to be very different from those of their parents, and the resultant fruit frequently lacks desired characteristics. Generally, apple cultivars are propagated by clonal grafting onto rootstocks. Apple trees grown without rootstocks tend to be larger and much slower to fruit after planting. Rootstocks are used to control the speed of growth and the size of the resulting tree, allowing for easier harvesting. There are more t ...

Meteosat 2
The Meteosat series of satellites are geostationary meteorological satellites operated by EUMETSAT under the Meteosat Transition Programme (MTP) and the Meteosat Second Generation (MSG) program. The MTP program was established to ensure the operational continuity between the end of the successful Meteosat Operational Programme in 1995 and Meteosat Second Generation (MSG), which came into operation at the start of 2004 using improved satellites. The MSG program will provide service until the MTG (Meteosat Third Generation) program takes over. __TOC__ First generation The first generation of Meteosat satellites, Meteosat-1 to Meteosat-7, provided continuous and reliable meteorological observations from space to a large user community. Meteosat-1 to -7 have all now retired. When operational, the Meteosat First Generation provided images every half-hour in three spectral channels (Visible, Infrared) and Water vapor, Water Vapour, via the Meteosat Visible and Infrared Imager (MVIRI ...

Geosynchronous Transfer Orbit
A geosynchronous transfer orbit or geostationary transfer orbit (GTO) is a type of geocentric orbit. Satellites that are destined for geosynchronous (GSO) or geostationary orbit (GEO) are (almost) always put into a GTO as an intermediate step for reaching their final orbit. A GTO is highly elliptic. Its perigee (closest point to Earth) is typically as high as low Earth orbit (LEO), while its apogee (furthest point from Earth) is as high as geostationary (or equally, a geosynchronous) orbit. That makes it a Hohmann transfer orbit between LEO and GSO. Larson, Wiley J. and James R. Wertz, eds. Space Mission Design and Analysis, 2nd Edition. Published jointly by Microcosm, Inc. (Torrance, CA) and Kluwer Academic Publishers (Dordrecht/Boston/London). 1991. While some GEO satellites are launched direct to that orbit, often the launch vehicle lacks the power to put both the rocket and the satellite into that orbit. Instead extra fuel is added to the satellite, the launch vehicle la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
