@bolun. Venus is underneath Vespa, Optsat 3000 is on top of Vespa. The satellite bus of both satellites are nearly identical.

It seems that both payloads are stacking on top of Vespa. Are they going to launch Vespa empty?
it may look that way but Venµs is inside Vespa as its smaller in Length.

Vega   July 25, 2017

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

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.

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’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).

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.
