Artist's view of the Proba-V satellite.

The ‘V’ in its name stands for Vegetation: Proba-V will fly a reduced-mass version of the Vegetation instrument currently on board the Spot satellites to provide a daily overview of global vegetation growth.

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assembly process for Vega no. 2 is being performed on the ZLV launch pad, protected by a mobile gantry that will be withdrawn prior to the vehicle’s liftoff.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 from French Guiana with the cornerstone Ariane 1 and 3 vehicles – having been updated and adapted where 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.

Vega launcher integration continues for its April mission from the Spaceport

March 4, 2013 – Vega Flight VV02
 
The no. 2 Vega light-lift launcher has been fitted with its solid propellant third stage, marking another milestone in preparations for its April mission from French Guiana with a multi-satellite payload.
 
In the latest activity at the Spaceport’s ZLV launch site, Vega’s Zefiro 9 stage was installed atop its lower two solid propellant stages, which were stacked during previous integration activity.
 
This clears the way for a “top off” of the basic Vega launcher with its bi-propellant liquid upper stage Attitude and Vernier Upper Module, which performs the attitude control and axial thrust functions during the final stages of flight – enabling the payload to be placed in orbit.
 
The flight next month will carry the Proba-V, VNREDSat-1A and ESTCUBE-1 satellites, and follows Vega’s on-target maiden launch in February 2012 with a payload of nine spacecraft – which served as its qualification mission.
 
Created by Europe as a capable lightweight launcher, Vega is tailored to orbit small- to medium-sized satellites, including institutional and scientific spacecraft. It joins the two other members of Arianespace’s vehicle family: the medium-lift Soyuz and heavyweight Ariane 5.

Vega resulted from a European Space Agency program led by Italy’s ASI space agency and industrial prime contractor ELV SpA.

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. It was developed in a European Space Agency program led by Italy’s ASI space agency and industrial prime contractor ELV SpA.

The two primary payloads for Vega’s second launch are readied at the Spaceport
 
March 14, 2013 – Vega Flight VV02
 
Payload preparations for the second Vega launch from French Guiana have commenced, with this upcoming mission’s two primary satellite passengers – VNREDSat-1A  and Proba-V – now undergoing their initial checkout at the Spaceport.   Vega is the lightweight member of Arianespace’s launcher family, which joins its medium-lift Soyuz and heavyweight Ariane 5 vehicles.

These pre-launch activities kicked off this month, following arrival of the two spacecraft in French Guiana. Preparations for VNREDSat-1A began inside the Spaceport’s S5A building, while Proba-V was based at the S1B clean room facility.

The VNREDSat-1A co-passenger on Vega will have a mass of approximately 120 kg. at liftoff.  It was built by Astrium on behalf of the Vietnam Academy of Science and Technology, and will support the Vietnamese government’s initiative to create an infrastructure enabling better studies of climate change effects, improving predictions for natural disasters and optimizing the country’s natural resource management.
 
Proba-V was produced by prime contractor QinetiQ Space Belgium for the European Space Agency and will have an estimated launch mass of 160 kg. Carrying a newer version of the Vegetation imaging instrument previously flown on the Spot series of Earth observation satellites – which also were orbited by Arianespace – Proba-V will monitor global vegetation growth.
 
Estonia’s first satellite, the 1.33-kg. ESTCube-1, will be lofted as well on the upcoming Vega mission.  Developed by students from Tartu University, the Estonian Aviation Academy, the Tallinn University of Technology and the University of Life Sciences, this small spacecraft has been evolved in conjunction with the Finnish Meteorological Institute and the German Space Center (DLR).
 
This upcoming mission – planned for April – is designated Flight VV02, and 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.

Estonia’s student cubesat satellite is ready for the next Vega launch

March 20, 2013 – Vega Flight VV02
 
The tiny spacecraft passenger for Vega’s upcoming Flight VV02 is getting the same “white glove” treatment as the launch’s two larger payloads, with Estonia’s ESTCube-1 student satellite now mission-ready at the Spaceport in French Guiana.
 
In the Spaceport’s S1B clean room, ESTCube-1 has been integrated in its box-type dispenser – readying the cubesat for integration in the Vega launcher’s payload “stack,” along with the Proba-V and VNREDSat-1A passengers.
 
ESTCube-1 is the first Estonian satellite, built by a collaboration of students from Tartu University, Estonian Aviation Academy, Tallinn University of Technology and University of Life Sciences, and was developed in conjunction with the Finnish Meteorological Institute and the German Space Center (DLR).

This spacecraft is 1U-category cubesat – sized at 10x10x10 cm. – which is the smallest of the nanosatellite types typically used for educational purposes and technology-proving applications. Weighing 1.33 kg., its purpose is to test electric solar wind sail technologies, as well as help establish an Estonian infrastructure for future space projects.
 
Vega Flight VV02 is the second launch for Arianespace’s lightweight vehicle and is being conducted in conjunction with the European Space Agency’s VERTA (Vega Research and Technology Accompaniment) program.

The VNREDSat-1A primary passenger for this mission will have a mass of approximately 120 kg. at liftoff, and is to support the Vietnamese government’s initiative to create an infrastructure enabling better studies of climate change effects, improving predictions for natural disasters and optimizing the country’s natural resource management. VNREDSat-1A was built by Astrium on behalf of the Vietnam Academy of Science and Technology.
 
As the Vega flight’s other primary passenger, Proba-V is to monitor global vegetation growth, equipped with a newer version of the Vegetation imaging instrument that previously was flown on the Spot series of Earth observation satellites – which also were orbited by Arianespace. The 160-kg. Proba-V spacecraft was produced by prime contractor QinetiQ Space Belgium for the European Space Agency.

With respect to previous Arianespace missions, there is nearly total silence about VEGA's second flight. Even, Proba-V blog is silent after 3-4 posts.

I wonder what is going on there?

There is plenty going on, but nothing that is interesting enough to publish status updates for.

Launch is still over 3 weeks away. The launch vehicle is now deep into testing to verify it's readiness to fly the missions. Such a phase is boring (unlike the stacking phase that looks visually interesting) and usually does not warrant the need for status updates. Same applies for the payloads. They are deep in pre-launch testing and integration on the payload adapter. And that's another one of those activities that don't warrant updates every 2 days.
But don't worry, the updates will resume once the launch date comes closer.

Yes, as of today. This flight will use standard version of Vespa dual-payload adapter which is derived directly from the Ariane IV family of dual-payload adapters and also has some Dnepr characteristics present.

Snap-proof space tether
 
27 March 2013

Space tethers hold intriguing potential for satellite manoeuvring, attitude control and even power generation. But about half of all orbital tether tests have either failed to deploy or snapped, probably due to micrometeoroid impacts.
 
This scanning electron microscope image shows the new design of an ultra-thin and hopefully snap-proof solar sail tether soon to be tested on Estonia’s ESTCube-1, which is being launched into orbit along with ESA’s Proba-V satellite on the next Vega rocket in April.
 
Harnessing manufacturing techniques from the microelectronics industry, this aluminium tether measures just 50 micrometres across – across half the diameter of the average human hair – with a smaller 25 micrometre wire interweaved onto it.
 
The University of Helsinki’s interweaving technique, with several wires joined together every centimetre, will hopefully keep the tether intact to run an electric charge down it, even if all but one subwires in the tether are cut.
