Israel’s first environmental satellite, named “Venus,” the major project of the Israel Space Agency and the French space agency CNES, will be launched from French Guinea at 4:58 a.m. on August 2.
Science and Technology Minister Ofir Akunis called the upcoming launch an “important national event.”
Israel, he said, is “known around the world for its boldness and innovation, which are expressed also in the technological developments of ‘Venus.’ We are so proud to see how work of many years of our best engineers and researchers at the head of the Israel Space Agency, along with CNES, will reach its peak at the launching.”
Environmental satellites have become very important in recent years because of problems on Earth resulting from population increase, declining space for agriculture, pollution and natural disasters.
The Venus, the world’s smallest satellite of its kind, was built in the last few years by Israel Aerospace Industries. It will observe fields and nature from space for environmental research, monitoring land conditions, forestry, agriculture, the quality of water sources and more.
The mini-satellite is equipped with a special camera that can visualize details on Earth that are invisible to the naked eye. It will take photos of set locations in Israel and around the world and provide researchers with scores of images daily, each of which will cover 760 square kilometers. The Venus will revolve around the Earth 29 times each 48 hours and repeat exact photo angles, making it possible to note differences in conditions – characteristics that make the satellite unique, the Science and Technology Ministry said.
The Venus satellite weighs only 265 kilograms. It will be launched along with an Italian satellite and reach its position 720 kilometers above Earth within 37 minutes and 18 seconds. The first confirmation of proper position and function should be received on the ground after five-and-a-half hours from launch time, but the initial images will arrive a week later.
Processed images will be sent to users three months after launch. The Venus is due to remain in operation for four-and-a-half years, after which time it will be shifted to a lower trajectory.
Some 110 different set research areas around the world will be photographed. When the satellite passes over Israel, the Venus will photograph three swaths in the Galilee, the coastal area and the Negev Desert, where most national parks, forests, ecological stations and nature areas exist. The photos will also benefit university, government and state research institutes.
Venus will transmit data to a reception station in northern Sweden. From there, the data will be processed initially by the French Space Agency, which will be led by French researcher Gerard Didiot. The images of Israel will arrive at the research center at the Sde Boker campus of Ben-Gurion University of the Negev, headed by Prof. Arnon Karnieli. The research center is an operational arm of the Science and Technology Ministry.
One of the first research projects to be used by the satellite simulations – funded by an investment of NIS 500,000 from the Israel Space Agency – will be one designed by high school pupils from Rishon Lezion and Rehovot.
Venus is also the first innovative technological mission of its kind to test the feasibility of a plasma-based electric propulsion system developed by Rafael Advanced Defense Systems, using an electric propulsion system that saves fuel and satellite weight to increase the weight of the equipment for research purposes.
Although the Venus is a joint project of Israel and France, all of the satellite’s hardware components were developed in Israel’s space industries. In addition to IAI, which built the satellite and integrated the components, Elbit developed the unique camera, and Rafael developed the propulsion system, resulting in the entire satellite being the product of Israeli construction and development.
Meanwhile, IAI president and CEO Yossi Weiss said that the Italian and the Israeli-French satellites are “the glory of Israeli technology and reflect Israel’s international activities in space and the extraordinary cooperation with Italy and France. The stateof-the-art observation satellites program enables the development and production of local needs and exports, and is supported by clear government policy in the field.”
He added, “On the eve of the launch, I call upon the Israel government to make the necessary decisions regarding the future of Israeli media satellites.
Since the loss of Amos-6 about 10 months ago, no decision has been made regarding the future of the field, which will eventually lead to the loss of knowledge and accumulated technological capabilities.
We are approaching the point of no return that could lead to the elimination of Israel’s capabilities in the field of communications satellites.”
