vega rocket launch 2020

Delivering a mean thrust of 190 tonnes over 111 seconds, the engine's behaviour was in line with predictions.The development of the Zefiro motor was initiated by The Zefiro 23 second stage engine was first fired on 26 June 2006 at Salto di Quirra. Vega’s first stage is powered by a large single-piece solid rocket motor (SRM) containing 87,710 kg. of liquid propellant (UDMH/NTO), distributed in four tanks. It contains also 38.6 kg. This European four-stage launcher is tailored to carry the growing number of small scientific spacecraft and other lighter-weight payloads under development or planned worldwide. of solid propellant HTPB 1912, providing maximum vacuum thrust of 1 120 kN. on missions to a 700-km. Vega's target payload lift capability is 1,500 kg. This European four-stage launcher is tailored to carry the growing number of small scientific spacecraft and other lighter-weight payloads under development or planned worldwide. It is designed to launch small payloads — 300 to 2500 kg However, it was recognised to be a costly project and thus difficult for Italy alone to finance; accordingly, international partners were sought early on in order to proceed with development.By September 1998, it was projected that, if fully funded, Vega would perform its first launch during 2002.Around 2000, an alternative use for the Vega was explored as a medium-class booster rocket to be used in conjunction with an improved, up-rated model of the Ariane 5 heavy launcher.In March 2003, contracts for development of the Vega launcher were signed by During October 2011, all major components of the first Vega rocket departed Avio's During mid-2011, it was postulated that an evolved 'Europeanised' upgrade of the Vega rocket could be developed in the medium-to-long term future.Following on from the first launch, a further four flights were conducted under the vestiges of the VERTA programme (Vega Research and Technology Accompaniment), during which observation or scientific payloads were orbited while validating and readying the Vega rocket for more lucrative commercial operations.Since entering commercial service, Arianespace markets Vega as a launch system tailored for missions to The payload fairing of the Vega was designed and is manufactured by The first three stages are solid propellant engines produced by Each of the three engine types intended for the three stages of the Vega had to be commissioned with two test-firings – one for design evaluation and one in the final flight configuration.The P80 is the first stage of VEGA, its name is derived from the design phase propellant weight of 80 tons that was later increased to 88 tons. Vega's target payload lift capability is 1,500 kg. At the end of the mission, it is deorbited under safe conditions to limit the amount of orbital debris.The AVUM contains about 577 kg. on missions to a 700-km. It is powered by an engine derived from the re-ignitable RD-869, providing 2.45 kN of thrust. These stages, each 1.9 meters in diameter, comprise a filament-wound carbon-epoxy case, with low-density EPDM insulation and a nozzle with flex-joints, equipped with electromechanical actuators to direct the thrust.The Zefiro 9 third stage is 4.12 meters long and is loaded with 10,567 kg of solid propellant HTPB 1912, providing maximum vacuum thrust of 317 kN. Payload to circular polar orbit The Arianespace commercial launcher family was expanded in 2012 with the addition of Vega, a new-generation vehicle for flights with small- to medium-sized satellite payloads. Although it is the smallest solid rocket motor on Vega, it offers the longest burn time, of approximately 120 seconds.The Vega’s second and third stages both use Zefiro solid rocket motors. The Arianespace commercial launcher family was expanded in 2012 with the addition of Vega, a new-generation vehicle for flights with small- to medium-sized satellite payloads. This successful test qualified the rocket engine.The first engine completed was Zefiro 9, the third stage engine. Vega has an essential role within the family of European launchers, joining Ariane 5 (which is optimized for large satellites on missions to geostationary transfer orbit, and low-Earth orbits with very heavy payloads), and Soyuz (tailored for medium weight payloads for low-Earth orbit and certain smaller GTO spacecraft). The Vega payload fairing – which is 7,880-meters-long and measures 2,600 meters in diameter – consists of two sandwich panel CFRP sheets, along with its aluminum honeycomb core.The AVUM (Attitude & Vernier Upper Module) has a bipropellant main propulsion system to provide orbital injection, and a monopropellant propulsion system for roll and attitude control.It is designed to inject different payloads into different orbits, and ensures the fine pointing of satellites prior to separation.
