Platform
 

Proba-V
 
 Proba-V's platform – otherwise known as its 'bus', the surrounding structure containing all necessary subsystems to let the payload do its work – takes its flight heritage from the Proba series of small satellites. The platform has been demonstrated in orbit by the Proba-1 and Proba-2 missions.
 
 The underlying design is recurrent from Proba-2. It is box-shaped, with precise dimensions 765 x 730 x 840 mm3. The platform is based around a H-structure with structural panels made from aluminium and carbon fibre reinforced plastic (CFRP) material. Unlike Proba-2, which has deployable panels, Proba-V will have its solar array mounted onto its satellite body.

 The satellite is three-axis stabilised, with an attitude and orbit control system inherited from Proba-2. incorporating a star tracker, GPS receivers, magnetometer and magneto-torquers.

 In an significant upgrade from previous Proba missions, the star trackers - as well as the Vegetation instrument payload – have been placed on an optical bench to minimise temperature-driven structural deformation. Navigation and manoeuvres take place on a largely autonomous basis, with minimal input from the ground.
 
The satellite has a design lifetime of 2.5 years, and possesses total system redundancy to make it single-failure tolerant.

Arianespace to launch VNREDSat-1A built by Astrium for Vietnam

Evry, January 4, 2013

Arianespace and Astrium today signed the launch contract for the VNREDSat-1A Earth observation satellite, on behalf of the Vietnamese Academy of Science and Technology. This ceremony was attended by ESA's Director General and by representatives of the Directorate of Launchers.

VNREDSat-1A will be launched during the second quarter of 2013 by the second Vega launcher, VERTA 1, performed by Arianespace at the Guiana Space Center, French Guiana, for the European Space Agency (ESA). The satellite will be carried in the lower position on the Vespa multiple launch structure used for this mission.

Both Astrium and Arianespace were pleased with this contract, which further expands bilateral cooperation between Vietnam and France, as the two countries celebrate the 40th anniversary of their diplomatic relations, established in 1973.

An optical observation satellite, VNREDSat-1A will be injected into sun-synchronous orbit (SSO) at an altitude of 670 km. The 120-kg satellite is being built by Astrium, which will supply to Vietnam the complete satellite system and ground receiving facilities.

Arianespace's family of launch vehicles, Ariane 5, Soyuz and Vega, is perfectly suited to satellites based on Myriade or AstroSat-100 platforms, such as VNREDSat-1A. Arianespace has already launched 12 satellites of this type from the Guiana Space center, seven using Ariane 5 (4 Essaim, 2 Spirale, Parasol), and five using Soyuz (4 Elisa, SSOT). Another satellite using this type of platform is also scheduled for an Arianespace launch.

Commenting on this latest launch contract, the first signed in 2013, Arianespace Chairman and CEO Jean-Yves Le Gall said: "We are especially proud of once again being able to work with Vietnam, following the successful launches of Vinasat-1 and -2 communications satellites. With this contract, the fourth we signed for Vega, Arianespace clearly shows that it can offer customers a launch service perfectly adapted to this type of mission. We would also like to thank Astrium and Vietnam for placing their trust in us. We are very pleased to be working once more with Astrium, after having launched five of their satellites during the last four months of 2012."

Vietnamese satellite booked for second Vega launch
BY STEPHEN CLARK
SPACEFLIGHT NOW
Posted: January 4, 2013

Vietnam's first Earth observation satellite will be launched in April on the second flight of Europe's Vega launcher, Arianespace announced Friday.

The VNREDSat 1A satellite will be paired with the European Space Agency's Proba-V environmental payload for the launch, which will mark the first use of the launcher's Vespa dual-payload adapter.

Arianespace, the company responsible for commercial Vega launch services, signed the contract Friday with EADS Astrium, which is building the satellite for the Vietnamese Academy of Science and Technology.

The Vega rocket successfully completed its first launch in February 2012, delivering a laser ranging satellite and a cache of smaller payloads to orbit.

ESA's Proba-V environmental satellite was assigned last year to the second Vega launch. But Arianespace and ESA, which is managing the mission as a demonstration launch, did not disclose what other satellites would be carried on the second Vega flight.

With the addition of VNREDSat 1A, the April launch mark the first test the rocket's Vespa dual-payload adapter. Proba-V will ride in the upper position of the Vespa adapter, and VNREDSat 1A will sit in the lower position in the structure.

The Vega rocket will launch from the Guiana Space Center, a European-run spaceport in French Guiana.

The 352-pound Proba-V satellite will be released first in the Vega's launch sequence. Proba-V will fly in a sun-synchronous orbit 500 miles above Earth and monitor global vegetation growth.

The Vega's liquid-fueled upper stage will deploy the 264-pound VNREDSat 1A spacecraft in a 416-mile-high sun-synchronous orbit for its mission to collect high-resolution optical imagery.

The April launch is the first of five ESA-sponsored Vega demonstration flights to test the launcher's capabilities, set a operational production cadence, and improve customer service before Vega begins commercial missions.

The Italian-led Vega rocket project, developed at a cost of $1 billion, is aimed at providing small European government payloads an indigenous launcher capability, reducing Europe's reliance on Russian rockets to do the job.

Arianespace will assume commercial operations of the Vega rocket, which will join the Ariane 5 heavy-lift launcher and the Russian Soyuz rocket based at the Guiana Space Center.

Первый эстонский космический спутник полетит в космос весной

00:1114.01.2013 (обновлено: 00:12 14.01.2013) / 2 / 390
В открытом космосе ESTCube-1 должен выпустить 15-метровый алюминиевый нанопровод — электрический солнечный парус, который может заставить космический аппарат передвигаться, используя поток исходящих от Солнца заряженных частиц.

ТАЛЛИН, 14 янв — РИА Новости, Николай Адашкевич. Работы по изготовлению первого космического спутника завершаются в Эстонии, весной аппарат под названием ESTCube-1 будет запущен из Франции на околоземную орбиту, сообщило в воскресенье Эстонское телевидение.

Мини-спутник разработан и изготовлен эстонскими студентами для испытаний изобретенной в Финляндии технологии солнечного паруса. Согласно проекту ученого из Института метеорологии Финляндии Пекки Яанхунена, с помощью нанопроводов, толщина которых в два-три раза тоньше человеческого волоса, можно заставить космический аппарат передвигаться, используя для этого поток заряженных частиц, исходящих от Солнца.

Свой вклад в разработку спутника внесли около ста студентов и научных сотрудников. Тестирование аппарата будет проходить вплоть до запуска. "Даже маленькая ошибка может вывести аппарат из строя. В целом такие вещи случаются редко, но часть ошибок очень сложно найти", — сказал разработчик электросистемы EstCube-1 Эрик Илбис.

Масса разобранного пока на части эстонского спутника ESTCube-1 составляет чуть более килограмма. В открытом космосе ESTCube-1 должен выпустить 15-метровый алюминиевый нанопровод — электрический солнечный парус, который может заставить космический аппарат передвигаться, используя поток исходящих от Солнца заряженных частиц.

Вы не подскажете адрес, по которому можно найти описание идеи?

И вопрос (в части выделенного); как оно будет "стоять"?

И вопрос к РИА Новости: они знают, что такое "нано"? В несколько раз тоньше человеческого волоса - это на порядки больше "нано".

First stage of second Vega ready at Europe's Spaceport
04 February 2013


P80 VERTA 1 loaded motor case

The first stage of the second Vega rocket, VV02, is now sitting on its launch pad at Europe's Spaceport in French Guiana.

The arrival of 'Assembly A1A', consisting of Interstage 0/1, the P80 solid-propellant motor and its thrust-vectoring system, marks the start of the launch campaign.

Initially shipped empty from Avio's Colleferro premises in Italy, the P80 was loaded with 88 tonnes of propellant in Kourou at the Regulus facilities, and then integrated by Europropulsion with its nozzle and pyrotechnic igniter.


Nozzle integration

Interstage 0/1, thermal protection, electrical harness and the thrust-vector electromechanical system were added in Kourou's Batiment d'Integration Propulseur.

Vega VV02 is the first of the five flights scheduled in ESA's Vega Research and Technology Accompaniment – VERTA – programme, which aims to demonstrate the flexibility of the launch system. At a minimum rate of two launches per year, the programme will allow the smooth introduction of Vega for commercial exploitation.


Electromechanical actuator installation

VV02 will loft Proba-V, the first of four ESA missions, into space. Proba-V carries a reduced version of the Vegetation instrument currently flying on the Spot satellites to provide a daily overview of global vegetation growth.  

This first VERTA flight will also demonstrate Vega's capability to launch multiple payloads. The second payload is the Vietnam Natural Resources, Environment and Disaster Monitoring Satellite (VNREDSAT) built by Astrium for the Vietnamese government.

The Vega team, including industrial colleagues from prime contractors, is now checking the first stage and preparing for the next step: adding the second stage of Europe's small launcher.

Planned to be launched in 2013, ESA's Proba-V mission will perform daily tracking of global vegetation growth. At the same time, the small satellite will also monitor the space environment with a compact radiation instrument.

Proba-V's Energetic Particle Telescope (EPT) will record the charge, energy and angle of incoming charged particles along a wide range of energies across a 50° field-of-view.

The Proba satellites are part of ESA's In-orbit Technology Demonstration Programme: missions dedicated to flying innovative technologies.

The light-lift member of Arianespace's launcher family is readied for its second mission

    February 21, 2013 – Vega Flight VV02

    The Spaceport's ZLV launch site in French Guiana is busy with activity as the second Vega undergoes its assembly for a mission scheduled in April.

    Build-up of the smallest member in Arianespace's launcher family marked a new milestone this week when its solid propellant second-stage was integrated atop the first stage, which also uses solid propellant.

    The vertical assembly process for Vega no. 2 is being performed on the ZLV launch pad, protected by a mobile gantry that will be withdrawn prior to the vehicle's liftoff. This complex uses the same site previously employed for missions fr om French Guiana with the cornerstone Ariane 1 and 3 vehicles – having been updated and adapted wh ere needed to meet operational requirements of the new lightweight launcher.

    Vega's upcoming second flight will orbit the Proba-V and VNREDSat-1A satellites, and follows the light-lift vehicle's on-target maiden launch in February 2012 with a payload of nine spacecraft – which served as its qualification mission.

    The Proba-V passenger for Vega's no. 2 launch was produced by prime contractor Qinetiq Space Belgium for the European Space Agency, and will monitor global vegetation growth. With an estimated mass of 160 kg., it is to operate in a Sun-synchronous polar orbit, carrying a newly-designed version of the Vegetation instrument already flown on the Spot series of Earth observation satellites – which also were orbited by Arianespace.

    Vega's VNREDSat-1A co-passenger is an optical observation spacecraft built by Astrium on behalf of the Vietnam Academy of Science and Technology. With a mass of approximately 120 kg., it will support the Vietnamese government's initiative to create an infrastructure that enables better monitoring and studies of climate change effects, improves predictions and actions to prevent natural disasters, while also optimizing the management of its natural resources.

    The four-stage Vega was conceived as a capable lightweight launcher, joining Arianespace's medium-lift Soyuz and heavyweight Ariane 5 to provide a complete family of vehicles that meet the company's motto of delivering "any payload, to any orbit...anytime." Developed in a European program led by Italy's ASI space agency and industrial prime contractor ELV SpA., Vega is tailored to orbit small- to medium-sized satellites, including institutional and scientific spacecraft.

    For Vega's April mission, the launch is designated Flight VV02 in Arianespace's numbering system, with the first "V" representing the French word for flight ("vol"), and the second letter referring to Vega. This will be the start of five flights scheduled in the European Space Agency's VERTA (Vega Research and Technology Accompaniment) program, which aims to demonstrate the launch system's flexibility as well as its ability to carry multiple satellite passengers.


    Assembly activity with the no. 2 Vega is highlighted in these images from the Spaceport's ZLV launch site.

   
    The solid propellant second-stage is raised for its installation atop Vega's first stage, which is partially visible in the mobile gantry at the background.

Vega receives its upper stage as the next mission's two primary passengers land in French Guiana

March 11, 2013 – Vega Flight VV02

Both primary payloads for Vega's no. 2 flight have arrived at French Guiana, positioning them for integration on the light-lift launcher – which has marked another step in preparation for its mission in April from the Spaceport.

On the launch pad, the basic Vega vehicle has been "topped off" with its upper stage, called the AVUM (Attitude and Vernier Upper Module). This system performs the attitude control and axial thrust functions during the final phases of Vega's mission profile, enabling the payload to be placed into orbit. Unlike the launcher's three lower solid propellant stages, the AVUM uses liquid bipropellant for primary maneuvering, along with cold gas for attitude control.

The AVUM's integration atop Vega was performed inside the ZLV launch site's mobile gantry. This Spaceport facility originally was used for missions of the Ariane 1 and Ariane 3 vehicles, with its mobile gantry, launch pad and infrastructure updated and adapted to meet the operational requirements of Arianespace's new lightweight vehicle.

While Vega is taking shape at the Spaceport, its Proba-V and VNREDSat-1A satellites have touched down in French Guiana aboard a chartered Boeing 747 cargo aircraft that arrived at Félix Eboué Airport near the capital city of Cayenne.

Proba-V will have an estimated mass at launch of 160 kg., and was produced by prime contractor QinetiQ Space Belgium for the European Space Agency. Operating in a Sun-synchronous polar orbit after its deployment by Vega, this satellite will monitor global vegetation growth. The spacecraft carries a newly-designed version of the Vegetation instrument previously flown on the Spot series of Earth observation satellites, which also were orbited by Arianespace.

The VNREDSat-1A co-passenger on Vega is an optical observation spacecraft built by Astrium on behalf of the Vietnam Academy of Science and Technology, and will have a mass at liftoff of approximately 120 kg. It is to support the Vietnamese government's initiative to create an infrastructure enabling better monitoring and studies of climate change effects, while also improving predictions and actions to prevent natural disasters and optimizing the country's management of its natural resources.

Joining them on the upcoming Vega mission is Estonia's first satellite – the 1.33-kg. ESTCube-1 – being developed by students from Tartu University, the Estonian Aviation Academy, the Tallinn University of Technology and the University of Life Sciences, all working in conjunction with the Finnish Meteorological Institute and the German DLR space center.

ESTCube-1's main mission is to test a novel space propulsion technology based on the electric solar wind sail concept, with this 10 x 10 x 10-cm. mini platform carrying a deployable 10-meter-long tether to be unreeled in orbit and electrically charged.

Vega's mission in April is designated Flight VV02 in Arianespace's numbering system, with the first "V" representing the French word for flight ("vol"), and the second letter referring to Vega. It is one of the flights scheduled in the European Space Agency's VERTA (Vega Research and Technology Accompaniment) program, which aims to demonstrate the Vega launch system's flexibility as well as its ability to carry multiple satellite passengers.

The four-stage Vega is tailored for small- to medium-sized satellites, complementing Arianespace's medium-lift Soyuz and heavyweight Ariane 5 to provide a complete family of vehicles.
