Vega begins its ascent from the Spaceport in French Guiana, carrying Italy’s PRISMA Earth observation satellite on the third Arianespace mission of 2019.Arianespace’s third mission of 2019 – which marked the Vega rocket’s 14th consecutive success – orbited the Italian PRISMA Earth observation satellite tonight, bringing the total number of spacecraft lofted by the launch services company to 600. It was the 308th flight overall of an Arianespace launcher.
The assembled Vega launcher for Arianespace Flight VV14 is shown at the Spaceport. The light-lift vehicle is protected by a mobile gantry which will be rolled back prior to the liftoff on March 21.Vega deployed its payload into Sun-synchronous orbit during a 54-minute mission performed from the Spaceport in French Guiana. The PRISMA satellite had an estimated liftoff mass of 879 kg., with the Vega launcher delivering a total payload lift performance of 953.5 kg. – which included integration and deployment system hardware.
PRISMA (PRecursore IperSpettrale della Missione Applicativa) was produced for the Italian ASI space agency by OHB Italia as prime contractor, with Leonardo responsible for the Earth observation system. Operating from low Earth orbit, the satellite is designed to provide major applications for protection of the planet and for Italy’s national environmental safety. It is equipped with a state-of-the-art electro-optical instrument with a medium-resolution camera and an innovative hyperspectral sensor. Once operational, PRISMA will provide data for environmental monitoring, resources management, the identification and classification of crops, the fight against pollution and other uses.
The 70th Earth observation payload launched by ArianespaceDesignated Flight VV14 in Arianespace’s launcher system numbering system, tonight’s mission underscored the company’s role in deploying Earth observation satellites, as PRISMA was the 70th spacecraft orbited by the company for this type of application.
“There was no better way for Vega to start the year 2019 than with this 14th success in a row…congratulations to all!” said Luce Fabreguettes, Arianespace’s Executive Vice President – Missions, Operations & Purchasing. “The PRISMA satellite is fully in accordance with Arianespace’s motto: Space at the service of a better life on Earth.”
It was highly appropriate that PRISMA was orbited by Vega for Italy, as this lightweight launch vehicle is delivered for launch to Arianespace by Italian production prime contractor AVIO.
Flight VV14 followed Arianespace’s two previous year-opening successes in 2019: the first, performed on February 5, utilized a heavy-lift Ariane 5 to place the Saudi Geostationary Satellite 1/Hellas Sat 4 and GSAT-31 communications relay platforms into geostationary transfer orbit; while the second employed a medium-lift Soyuz vehicle on February 27 to deploy the first six satellites into a circular low Earth orbit for the OneWeb communications constellation.
After tonight’s Flight VV14, preparations continue for Arianespace’s next mission – Flight VS22 – which will use a Soyuz launcher to orbit four additional satellites for the SES-owned O3b satellite constellation. Flight VS22 is scheduled for April 4 from the Spaceport.

Credit: Arianespace video still.WASHINGTON — European launch provider Arianespace conducted its third launch of the year March 21, orbiting a remote-sensing satellite for the Italian Space Agency on a Vega rocket.
Vega, Arianespace’s light-lift vehicle, took off from Europe’s spaceport in Kourou, French Guiana at 9:50 p.m. Eastern. PRISMA, the PRecursore IperSpettrale della Missione Applicativa satellite, separated from the rocket 54 minutes later.
The launch is the first of four Vega missions planned for this year. If none are delayed, it will be the highest number of Vega launches in a single year since the rocket’s introduction in 2012.
PRISMA was originally scheduled to launch in 2018, but delays with the European Space Agency’s Aeolus wind-mapping satellite, which also called for a Vega launch,
pushed PRISMA into 2019.
ASI, the Italian space agency, assembled a roster of Italian companies to execute the PRISMA mission.
OHB Italia built the 879-kilogram satellite with Italian aerospace and defense company Leonardo, which supplied the electro-optical payload, solar panels and power supply unit.
Thales Alenia Space, a joint venture between Paris-based Thales Group and Leonardo, supplied PRISMA’s onboard data transmission system.
Data acquisition and processing will take place at Telespazio’s Matera Space Centre.
OHB Italia was also responsible for arranging the launch, for which it choose the Italian-led Vega rocket built by Avio.
PRISMA carries what the Italian space agency called the “most powerful operative hyperspectral instrument in the world.” The satellite’s imaging payload is designed to see in 239 spectral bands, plus panchromatically.
PRISMA has a design life of five years, not counting in-orbit commissioning. Christiano Contini, PRISMA mission director at OHB Italia, said the satellite’s commissioning is expected to take three months.
ASI said the satellite will be used to study environmental behavior, including climate change and other human-influenced changes. ASI said such data will be applicable to a wide range of activities, from natural disaster prevention to pollution monitoring, disaster response and agriculture.
The satellite will operate in a 615-kilometer sun-synchronous orbit.
Luce Fabreguettes, Arianespace’s executive vice president of missions, operations and purchasing, said in post-launch remarks that Arianespace’s next launch will take place April 4. The company will use a Soyuz rocket to launch four O3b satellites for SES, expanding the medium Earth orbit system to 20 satellites.

The $143 million (126 million euro) PRISMA mission is led by the Italian space agency, known as ASI, and is designed to monitor the environment, track pollution and water quality, and chart the growth of forests and crops. After a thorough checkout in orbit, PRISMA is scheduled to begin a five-year operational mission beginning in June, according to an ASI spokesperson.
PRISMA stands for PRecursore IperSpettrale della Missione Applicativa, or the Hyperspectral Precursor and Application Mission. The satellite will collect imagery of Earth in numerous spectral bands, breaking the sunlight reflected off the planet’s oceans, forests, and cities into 240 parts to resolve parameters such as plant health, soil erosion and chemistry, oil spills, water salinity, and natural resources.
The satellite’s instrument combines the hyperspectral sensor, with sensitivity in 239 bands, with a medium-resolution panchromatic, or black-and-white, camera providing context views.
“PRISMA is a fully Italian Earth observation mission based on a single satellite carrying a hyperspectral imager that will characterize the Earth’s surface on a global scale, extracting geochemical, biochemical and geophysical parameters, providing unique information on the status and evolution of our planet,” said Francesco Longo, PRISMA’s project manager at ASI.
The Italian space agency started working on the PRISMA mission after the cancellation of a previous hyperspectral imaging satellite named HypSEO in the early 2000s. PRISMA itself was delayed several years as engineers developed the satellite and its payload, both of which are based on new designs.
“Hyperspectral imaging is a novelty of remote sensing technology that acquires image data in hundreds of narrow continuous bands from the visible to the shortwave infrared,” Longo said. “Each individual pixel of the hyperspectral image contains a continuous spectrum of the solar radiation reflected by the surface. These spectra include absorption features which can be interpreted as spectral fingerprints of Earth’s elements. That allows the identification of mineral types and soils … vegetation types and conditions, and to detect pollutants in water and air.”
Italian officials described PRISMA as the most capable environmental satellite of its kind, combining the hyperspectral sensor and electro-optical camera into one instrument. (...)
