📰 After the success of the inaugural flight of Vega-C, its evolution Vega-E in the pits

ESA’s new Vega-C rocket has just completed its maiden flight, placing the main LARES-2 payload, a scientific mission of the Italian space agency ASI, into its scheduled orbit. Six research CubeSats from France, Italy and Slovenia were also trip (A trip is a trip that is made to a more or less distant point with a personal purpose…) as secondary payloads. This launch crowns years of effort by ESA, Avio, the prime contractor, and industrial partners from 13 ESA Member States, to build on the legacy of Vega (Vega is a European Space Agency (ESA) launcher made in collaboration…)his predecessor.

Flight VV21 took off from the spaceport of theEurope (Europe is a land region that can be considered as…) in French Guiana at 15:13 CEST on Wednesday, July 13 (14:13 BST/10:13 hour (Time is a unit of measurement 🙂 local Kourou). The mission lasted approximately 2 hours and 15 minutes (Primary form of a document: Law: an act is the original of a…) from the take off (Takeoff is the transition phase during which an aircraft transitions from the state…) until the release of load utility (The payload represents what it really is…) end and theswitched on (In order to ignite, the air-gasoline mixture, a gas contained in the cylinder, must undergo…) at the end engine (A motor (from the Latin mōtor: “the one that moves”) is a device…) AVUM+ on the top floor.

The dough (The term mass is used to designate two quantities joined to one…) of collect (The payload represents what it really is…) the payload at liftoff was approximately 474 kg: 296 kg for LARES-2, the residual payload is made up of six CubeSats, payload adapters and support structures.

Vega-C represents a dramatic increase in capacity over Vega, which has been flying since 2012. With its new first and second stages and an improved fourth stage, Vega-C increases Vega’s performance from 1.5 tons to approximately 2.3 tons in one orbit (In celestial mechanics, an orbit is the path traced by a body in space…) 700 km polar reference.

Vega-C has a new and more powerful first stage called P120C, based on Vega’s P80. On top of this is a second stage, Zefiro-40 and then Zefiro-9, the third stage identical to that used on Vega.

The resettable upper stage has also been optimized. To be able to send payloads to multiple orbits as required by the mission and allow extension of the temperatures (Time is a concept developed by the human being to apprehend the…) operations in space, and therefore extended missions, AVUM+ has more storage capabilities than liquid propergol (In astronautics, liquid propellant is any chemical system composed of one or…).

The P120C engine will be used twice, with 2 or 4 units serving as boosters for Ariane 6. Sharing this module streamlines industrial efficiency and optimizes the profitability of the two launchers.

With its taller main stages and wider headdress (doubling the volume (Volume, in physical or mathematical sciences, is a quantity that measures extension…) payload compared to Vega), Vega-C is 34.8 meters tall, almost 5 meter (The meter (symbol m, from the Greek metron, measure) is the basic unit of length of…) of plus than Vega.

The new setting of rocket launcher (Pitcher, astronautics term Pitcher, baseball term) constitutes a nice (The term Nette is a vernacular name attributed in French to various species…) improved flexibility of the launch system. Vega-C is capable of orbiting larger satellites, two main payloads, or adapted to various configurations for shared-path missions. space rider, the next vehicle (A vehicle is a mobile machine, which allows people or loads to be moved from one…) back to Land (Earth is the third planet in the Solar System in order of distance…) ESA, will be launched into orbit by Vega-C.

The goal of the mission is to measure the effect “of streak (In fluid mechanics, resistance is the force that opposes the motion of a…) of frame (The word plot can designate:)“, a distortion of thespace time (The notion of space-time was introduced in the early 20th century and was revived…) caused by the rotation of a body solid (The word massive can be used as:) like the Earth, as predicted by the theory of relativity (This article deals with the theory of relativity through the ages.

future evolution

As Vega-C begins operations, its development continues. Vega-E, another variant, will start from 2026 to provide a architecture (Architecture can be defined as the art of constructing buildings). simplified by replacing both the third and fourth stages of Vega-C with a new cryogenic upper stage. The centerpiece of the Vega-E is the European-made M10 engine that uses less environmentally harmful propellants (fromoxygen (Oxygen is a chemical element of the chalcogen family, of…) liquid (The liquid phase is a state of matter. In this form, matter is…) cryogenic and methane) and has a system of control (The word control can have several meanings. It can be used as a synonym of examination, of…) of Pressure (Pressure is a fundamental physical notion. You can think of it as an informed force…) advanced that allows multiple stops and restarts in space. Avio, the main contractor, recently completed its first round of hot tests.

VV21 was administered by ESA, owner of the Vega-C program and supervisor of its development. The inaugural flight paves the way for the start of operations of arianespace (The private company Arianespace SA founded in 1980 is, in its own words,…) and Avio.

Following the success of Vega, ESA member states agreed in the meeting (Réunion is a French island in the southwestern Indian Ocean located…) interministerial meeting in December 2014 to develop the rocket (Rocket may refer to:) More powerful Vega-C to meet a changing market and long-term institutional needs. ESA Member States participating in the Vega-C program are Austria, Belgium, the Czech Republic, France, Germany, Ireland, Italy, the Netherlands, Norway, Romania, Spain, Sweden and Switzerland.

Since 2012, Vega has played a key role in the space transportation sector. Its current development and its future evolutions, as well as Ariane 6, will allow it to further increase its competitiveness beyond 2025. This is a response to the rapid growth of global competition. It offers a family of configurations based on common blocks. Higher performance will also be added with the development of the P120C+ (an upgraded version of the P120C) in Vega-C and Vega-E.
