VENµS (Vegetation and Environment monitoring on a New MicroSatellite) is an earth observation satellite of the Israel Space Agency (ISA) and the French space agency CNES .
It was launched into sun-synchronous orbit on August 2, 2017 at 1:58:33 UTC with a Vega launcher from the rocket launch site in Kourou (together with OPTSAT-3000 ).
The three-axis stabilized satellite is equipped with a multispectral camera and is intended to provide images for monitoring the vegetation. For this purpose, certain areas should be recorded every two days and the changes evaluated. The camera simultaneously delivers images in 12 different spectral ranges in the infrared and in the visible range with a resolution of 5 m and a swath width of 27 km. It was built on the basis of the IMPS (Improved Multi Purpose Satellite) satellite bus from Israel Aerospace Industries (IAI). The satellite will fly in a 720 km high orbit for the first two and a half years of its mission before launching the Hall Effect propulsion, which is expected to bring it into a 410 km high and two degrees less inclined orbit. After reaching the new orbit, VENμS will try to hold it for as long as possible and provide images with higher ground resolution as a result of the shorter distance to Earth. The first agreement between the French space agency CNES and the Israeli space agency was signed back in 2005, with a start in early 2008. Israel should spend around $ 20 million on this, while France should contribute $ 13 million. Israel Aircraft Industries was responsible for the construction of the satellite, Elop Electro-Optics Industries was entrusted with the development of the multispectral camera, while France is responsible for technical support, project management and the scientific aspect of the mission (data processing, analysis, archiving and distribution) . The Israeli company Rafael provided the Hall-effect drive that is to be tested during the mission. VENµS was supposed to be a sample mission for the European Copernicus program, but has been overtaken by other missions due to long delays.
