Flight VV10: Vega to launch two Earth Observation Satellites for Italy, Israel and France



For its eighth launch of the year, and the 10th Vega mission since this launcher began its career at the Guiana Space Center in 2012, Arianespace will orbit two Earth observation satellites for civil and military applications: OPTSAT-3000 for the Italian Ministry of Defence; and Venµs, a mission of the Israel Space Agency (ISA) – a government body sponsored by the country's Ministry of Science & Technology – and the French CNES space agency (Centre National d'Etudes Spatiales).

This marks the seventh Earth observation mission for the versatile Vega launch vehicle.

The launch will be performed from the Vega Launch Complex (ZLV) in Kourou, French Guiana.

The Launch Readiness Review (LRR) will take place on Monday, July 31, 2017 in Kourou, to authorize the start of operations for the final countdown.

OPTSAT-3000 is an Earth observation program for the Italian Ministry of Defense. It comprises a high-resolution optical satellite and a ground segment for in-orbit control, mission planning and the acquisition and processing of images.

OPTSAT-3000 will allow national defense entities to acquire and use high-resolution images from any part of the globe. The OPTSAT-3000 system will be interoperable with Italy's second-generation COSMO-SkyMed radar satellites. This will give the Italian Defense Ministry access to state-of-the-art technology, and ensure maximum operational capabilities because of the combined optical and radar data offered by the two systems.

The OPTSAT-3000 system is supplied by prime contractor Telespazio, a joint venture between Leonardo (67%) and Thales (33%). Telespazio is responsible for the entire system, including the satellite, ground segment, launch and early orbital operations, preparation and execution of operations and logistics, in-orbit tests and commissioning.

The satellite and ground control systems were built by Israel Aerospace Industries (IAI), chosen by the Italian Ministry of Defense on the basis of an inter-governmental agreement between Italy and Israel. OHB Italia is responsible for the launch services and related engineering support.

OPTSAT-3000 is a three-axis stabilized satellite, highly autonomous and combining reduced weight, low power consumption and high reliability.

Venμs is an Earth observation and exploratory mission of the Israel Space Agency (ISA) – a government body sponsored by the country's Ministry of Science & Technology – and the French CNES space agency (Centre National d'Etudes Spatiales).

While the satellite's designation may sound like the name of a planet, it actually is the acronym for: Vegetation and Environment monitoring on a New Micro Satellite. By analyzing and comparing images taken from the same location, researchers will be able to assess the state of the soil, understand how vegetation is developing, and detect the spreading of disease or contamination in the field.

The satellite will image vast areas around the globe and provide dozens of images every day, each of them covering approximately 760 square kilometers. Venμs will fly in a Sun-synchronous, near-polar orbit – which enables its return to view each area around the world, exactly at the same time and under the same imagery conditions.

Venμs is equipped with a multi-spectral camera that can capture important details, some of which are not visible to the human eye.

CNES is in charge of the multi-spectral instrument (camera), the image processing and the image distribution ground station. Elbit Electro-Optic Systems, Elop Ltd. developed the camera for CNES.

ISA is in charge of development and integration of the satellite, the platform, the monitoring and control center, and the electrical propulsion system. Israel Aerospace Industries (IAI) was the main integrator of the system, as well as developer of the platform and ground control system.

Vega receives its OPTSAT-3000 and Venµs payloads for Arianespace's August 1 mission


Vega's completion is highlighted in this photo series, beginning with encapsulation of the two satellite passengers – OPTSAT-3000 and Venµs – inside their protective payload fairing (photo at left). This component – called the "upper composite" – was then moved from the Spaceport's S3B facility to the SLV launch site on a special transporter (center), hoisted to the appropriate level of the mobile gantry, then integrated with the light-lift vehicle (right).

Build-up of the lightweight Vega for Arianespace's upcoming mission to orbit twin Earth observation satellites is complete in French Guiana, with the OPTSAT-3000 and Venµs spacecraft now integrated with their launch vehicle.
Спойлер
During activity on the Spaceport's SLV launch site, the two passengers – which are integrated in their payload fairing – were installed on Vega, topping off the vehicle composed of three solid-propellant stages and a liquid bipropellant upper stage.

Vega will now undergo final preparations and checkout leading to a nighttime liftoff on August 1 for Arianespace Flight VV10, marking the 10th mission for this vehicle since its 2012 service entry.
As the smallest member in Arianespace's launcher family, Vega complements the company's medium-lift Soyuz and heavyweight Ariane 5 in providing a full range of launch services for customers worldwide. ELV/Avio is the vehicle's production prime contractor.

OPTSAT-3000 to be deployed first by Vega
To be deployed first during the mission to Sun-synchronous orbit is OPTSAT-3000 – an Earth observation satellite for the Italian Ministry of Defense. Built by Israel Aerospace Industries (IAI) based on inter-governmental Italian-Israeli agreements, it will enable national defense entities to acquire and use high-resolution images from any part of the globe.

The OPTSAT-3000 system was supplied by Telespazio as prime contractor, which has responsibility for the entire system: from the satellite to the ground segment, launch and early operation services, the preparation and execution of operations and logistics, through to in-orbit tests and commissioning. OHB Italia is responsible for the launch services and related engineering support.

With a design life exceeding seven years, OPTSAT-3000 has a liftoff mass of 368 kg.

Venµs puts the focus on Earth vegetation
Riding in the lower payload position on Vega is Venµs, an Earth observation and exploratory mission for the Israeli Space Agency (ISA) and France's CNES space agency at the benefit of the Israeli Ministry of Science & Technology.

As the first Israeli-made satellite created for environmental research purposes, Venµs was developed by Israel Aerospace Industries' Space Division, with Rafael providing the propulsion system. The spacecraft has a liftoff mass set at 264 kg.

CNES is in charge of the multi-spectral camera, its image programming and processing, as well as the distributing ground station, with the camera's development performed for CNES by Elbit Electro-Optic Systems Elop Ltd.

Venµs – which is the acronym for "Vegetation and Environment on a New Micro Satellite" – will study the evolution of the Earth's vegetation during its scientific mission, while the satellite's technological mission will provide in-flight qualification of the Israeli Electrical Propulsion System, based on Hall-Effect thrusters.

Flight VV10 will be Arianespace's eighth mission of 2017. It follows the launches of four Ariane 5s, two Soyuz vehicles and one Vega so far this year.

Vega launcher is getting ready for its 10th mission
Спойлер
[свернуть]
At Kourou, French Guiana, preparations continue apace for the next flight of the Vega launcher, which will soon carry out its tenth mission, the second one of 2017. Vega has completed the integration phase, with the assembly of the P80 solid propellant first stage, the Zefiro 23 second stage, the Zefiro 9 third stage, the AVUM (Attitude and Vernier Upper Module) liquid propellant fourth stage, and the upper part containing the satellites. The propellant loading operations are currently underway.

The launch starts on 1 August at 10:58 p.m. local time, 3:58 a.m. on 2 August in Rome. Vega will place into orbit two Earth observation satellites: OPTSAT-3000 and VENµS. The two satellites will be positioned in the nose cone using the VESPA (Vega Secondary Payload Adaptor) device: OPTSAT in the upper part and VENµS in the lower part.

VENµS (Vegetation and Environment on a New Micro Satellite) is designed to provide detailed and constant monitoring of the vegetation on Earth's surface. Observing the growth of plants and their state of health, the satellite will help scientists to determine the impacts on Earth's surface of environmental factors, human activity, and climate change. The other Earth observation satellite, OPTSAT-3000, will enable national defence entities to acquire and use high-resolution images from any part of the globe.

ЦитироватьVega Rocket set for Tuesday Night Liftoff with Satellites for Israel, France & Italy
July 31, 2017

Europe's Vega rocket stands ready for a nighttime liftoff from the edge of the Amazon jungle Tuesday night carrying a pair of satellites built in Israel for operation by the Italian defence ministry and a French-Israeli cooperation. Vega is targeting liftoff at 1:58:33 UTC on Wednesday and will be in action for 97 minutes to dispatch the two satellites into different orbits – taking advantage of the maneuverability of the rocket's AVUM upper stage.

Known as VV10 in Arianespace's numbering system of Vega missions, the flight will be the tenth for the smallest member in the company's launch vehicle fleet. It will be the eighth Arianespace-operated mission of the year, coming after four heavy-lift missions by Ariane 5, a pair of Soyuz launches to deliver satellites to Geostationary Transfer Orbit and Vega's VV09 mission that successfully delivered the Sentinel-2B satellite in March for the European Copernicus Program.

Hidden under Vega's payload fairing for Wednesday's mission are OPTSAT-3000, riding in the upper position affixed to a Vespa payload adapter, and VENµS that is riding in the lower passenger position for deployment after OPTSAT when the upper stage will have maneuvered into a higher orbit.

OPTSAT-3000 is a 368-Kilogram image-reconnaissance satellite built by Israel Aerospace Industries for operation by the Italian Ministry of Defence. The satellite was ordered in 2012 in an exchange deal contingent on Israel's purchase of Italian trainer aircraft. OPTSAT-3000 serves as a gapfiller for the Italian defence authorities until a next-generation space-based platform for the collection of optical reconnaissance will be available.

The 3.4-meter tall OPTSAT-3000 has a single instrument known as Jupiter, a powerful panchromatic and multi-band imaging system fed by a 70-centimeter telescope capable of collecting black and white imagery with a ground resolution of 0.5 meters and color images with a two-meter resolution which can be further improved through PAN-sharpening as both imaging branches can be operated simultaneously. Operating from a 450-Kilometer Sun Synchronous Orbit, OPTSAT-3000 will collect imagery across a 15-Kilometer wide swath, though the craft's agile pointing system allows imaging at off-nadir angles of up to 30 degrees and quick slew maneuvers can be used to capture multiple targets during a single pass.

The satellite in the lower passenger position on Wednesday's flight is VENµS, a 264-Kilogram dual-purpose satellite operated under a cooperation by the French and Israeli Space Agencies. VENµS – the Vegetation and Environment Monitoring New Micro-Satellite – had a long road to launch with the initial agreement between CNES and the Israeli Space Agency Signed in 2005. Under the project, Israel is responsible for manufacture of the satellite bus, the imaging instrument and the mission ground segment while France provides technical assistance, specifications for the instrument and the science ground segment that handles data processing, analysis and distribution.

VENµS, 1.7 meters tall and 1.2 meters in diameter, hosts a 25-centimeter aperture telescope feeding four detector assemblies holding a total of 12 line detectors for imaging in 12 spectral bands at a ground resolution of 5.3 meters. Superspectral imagery collected by the satellite will be used for ecosystem monitoring, capturing imagery of 50 sites that are representative of the world's inland and coastal ecosystems, providing information on vegetation cover and health and helping in the development for new automated extraction methods to turn satellite data into biosystem parameters. Data from the mission will also be useful for tracing the water and carbon cycles and further the current understand of the interface between land masses and the atmosphere.

>> VENµS Satellite Overview

2.5 years are budgeted for the VENµS imaging mission in an orbit of 720 Kilometers before the satellite will enter its second mission phase primarily dedicated to the demonstration of an Israeli Hall Effect Thruster for large orbit changes, orbital maintenance and drag-free flight. To that end, the satellite will employ an autonomous system that calculates the craft's power budget on an orbit-to-orbit basis to descend from 720 Kilometers into a 410-Kilometer Sun Synchronous Orbit over the course of around half a year, also modifying the orbital inclination to remain in a Sun Synch Orbit.

Once at 410 Kilometers, the satellite will operate the Xenon-fueled Hall Effect Thruster to counter drag and maintain altitude for one year, accumulating a large number of duty cycles and firing time on the thruster to qualify it for operational use on future projects. While at 410 Kilometers, the satellite will alternate between orbital maintenance and operating the super-spectral imager which will achieve a three-meter ground resolution from the lower orbit.

Vega's VV10 launch campaign began in May with the arrival of the launch vehicle components via one of two sea-going vessels tasked with shipping rocket parts from Europe to the South American launch base. Stacking of the three solid-fueled Vega stages was completed in the second half of June with the AVUM upper stage taking its spot atop the stack in early July.

The two passengers arrived on a Boeing 747 in late June to begin a multi-week preparations flow comprising final tests of the satellites, fueling for flight, and integration of the payload stack with VENµS hidden underneath the Vespa Adapter and the taller OPTSAT sitting atop the stack. Both passengers took their place on the Vega rocket by July 25 for a final set of testing activities leading into the Launch Readiness Review to clear the vehicle for its nighttime liftoff.

With an all-solid rocket and an upper stage carrying storable propellants, Vega will not require any dynamic operations such as propellant loading during its countdown. Countdown operations pick up at T-9 hours and 10 minutes and are largely focused on checks of the rocket's Multi-Function Unit that is in charge of controlling all aspects of the mission. Both payloads will be on internal power when Vega's automatic countdown sequence kicks off at T-4 minutes to put the rocket through final reconfigurations for liftoff.

Upon Ignition of its P80 first stage, Vega will literally jump off the ground – generating a total thrust of 280,000 Kilogram-force to lift the 137-metric-ton vehicle. Seconds after lifting off, Vega will pitch over to begin flying to the north, aiming for a Sun Synchronous Insertion.

>> Vega Launch Vehicle

The 11.2-meter long first stage will burn over 88 metric tons of solid propellant in just 115 seconds, accelerating the rocket to a speed of 1.7 Kilometers per second. Burnout on the first stage is sensed by the declining chamber pressure, triggering the pyrotechnic stage separation sequence at T+1:57 to set up for the ignition of the second stage, designated Zefiro-23.

The Z23, loaded with 24 metric tons of packed propellant, will soar to an average thrust of 122 metric-ton-force for a burn of 77 seconds.

Separation of the 8.4-meter second stage is expected at an altitude of 155 Kilometers at a speed of 3.8 Kilometers per second. Ignition of the Zefiro-9 stage comes around 23 seconds after Z23 separation at T+4:03. Although it is the smallest of the three stages, Z9 has the longest burn time – firing for 120 seconds at an average thrust of 23 metric-ton force.

The protective payload fairing will split open and separate four minutes and eight seconds into the flight when Vega will be well on its way out of the dense layers of the atmosphere.

>> Launch Profile

Stage 3 accelerates the vehicle to 7.6 Kilometers per second and separates six minutes and 42 seconds after launch when the vehicle will have reached 236 Kilometers in altitude. At that point, the AVUM – Attitude and Vernier Upper Module – assumes control of the flight, first tasked with stabilizing its orientation before coasting uphill for a little over a minute.


VV10 Flight Profile – Image: Arianespace

The AVUM will ignite its Main Engine Assembly (RD-869) at T+7 minutes and 52 seconds on a burn of just over six minutes to push the stack into orbit with a thrust of 250 Kilogram-force.

AVUM will be tasked with a relatively complex mission profile on Wednesday calling for a total of five burns the first of which is designed to inject the stack into a Parking Orbit peaking around 450 Kilometers in altitude. In that orbit, the vehicle will coast for half a lap around the planet before lighting up again 40 minutes and 37 seconds into the flight for an 85-second burn to circularize the orbit at 450 Kilometers.

OPTSAT-3000 will be first to depart the vehicle, separating 42 minutes and 49 seconds into the mission to set sail on its imaging mission for the Italian government. AVUM will drop the Vespa adapter ten minutes after OPTSAT separation and re-light the engine at T+53 minutes and 5 seconds on a 58-second burn to lift the high point of the orbit to 720 Kilometers. Then, it's another half orbit of coasting ahead of a 64-second circularization maneuver at T+95 minutes to set up the proper orbit for VENµS – targeting separation one hour and 37 minutes after liftoff to conclude the primary mission of Vega.

AVUM will be tasked with a 78-second retrograde deorbit maneuver ten minutes after dropping off its second passenger to remove itself from orbit, slowing by 217 meters per second to close out its mission with a fiery re-entry.

Vega is cleared for its August 1 liftoff with the OPTSAT-3000 and Venµs Earth observation satellites

The 10th Vega mission fr om French Guiana has been authorized for liftoff tomorrow following completion of its launch readiness review, which was conducted today at the Spaceport.

This assessment – held prior to each flight of an Arianespace launcher family member – confirmed that the lightweight vehicle and its multi-passenger payload are flight-ready, along with the Spaceport's infrastructure and the network of downrange tracking stations.

Tomorrow's mission is designated VV10 in Arianespace's numbering system, and it will be performed from the Spaceport's SLV launch site – wh ere the Vega was assembled and now stands in a flight-ready configuration, protected by a mobile gantry that will be withdrawn prior to liftoff.

Flight VV10 will mark Arianespace's eighth mission in 2017, and is the company's second this year using a Vega launcher – which is one of three launch vehicles operated by Arianespace at the Spaceport, along with the medium-lift Soyuz and heavyweight Ariane 5. Vega's production prime contractor is ELV, a company created by Avio and the Italian Space Agency.

A dual-passenger delivery for Vega
With today's readiness review completed, all is set for the August 1 nighttime liftoff – set for precisely 10:58:33 p.m. local time at the Spaceport in French Guiana. The flight to Sun-synchronous orbit will last approximately one hour and 42 minutes from liftoff to separation of its two passengers.

To be deployed first during the mission to Sun-synchronous orbit is OPTSAT-3000 – an Earth observation satellite for the Italian Ministry of Defence. Built by Israel Aerospace Industries (IAI) based on inter-governmental Italian-Israeli agreements, it will enable national defense entities to acquire and use high-resolution images from any part of the globe. The OPTSAT-3000 system was supplied by Telespazio as prime contractor, which has responsibility for the entire system; while OHB Italia is responsible for the launch services and related engineering support.

Riding in the lower payload position on Vega is Venµs, an Earth observation and exploratory mission for the Israel Space Agency (ISA) and France's CNES space agency at the benefit of the Israeli Ministry of Science & Technology. It was developed by Israel Aerospace Industries' Space Division, with Rafael providing the propulsion system.
