SENER, commissioned by OHB Italia and as part of the mission of the European Space Agency, has designed, manufactured and tested the Mechanical Ground Support Equipment to support the installation of a satellite that is 12 meters wide and 20 meters long.
The MGSE kit includes equipment for mounting and dismounting the satellite panels as well as structures for environmental testing of some of its instruments. The Biomass mission is part of the “Earth Explorer” scientific program, under which ESA conducts research on Earth from space and seeks answers to questions about changes in the environment and man’s impact on the biosphere.
Trees play a very important role in protecting the Earth’s ecosystem, producing oxygen and absorbing carbon dioxide, reducing its emission into the atmosphere. At the same time, data on the magnitude of deforestation is still inaccurate, because forest biomass in most areas of the Earth has never been accurately counted.
The European Space Agency wants to change this by launching the Biomass satellite into orbit, which by scanning the planet from space will provide the first accurate maps of forest biomass for temperate, tropical and boreal (northern) regions. The main research instrument of the ESA satellite is the SAR radar with a powerful 12 meter diameter antenna, the waves of which will penetrate the branches of trees and scan trunks and branches.
On this basis, a current three-dimensional map of the Earth’s forests will be created every six months… and that is not all. When the satellite will be ready in orbit, the possibilities of using its observation functions will be mainly limited by the imagination. The list of applications for SAR radar, in addition to “weighing” trees on the planet, may include, for example, monitoring glaciers and changes in the ice cap or scanning the land for archaeological buildings under the surface of the deserts.
The launch of the Biomass mission is planned for 2022. The satellite will be launched into LEO on board the Vega rocket. The mission is planned for five years, during which time SAR radar data will be delivered to the ground station in Kiruna, Sweden. The budget of the entire mission is 420 million euros.
Janusz Grzybowski, Project Manager for the Biomass mission at SENER in Poland, said, “Missions such as Biomass not only bring us closer to understanding the most important phenomena taking place on our planet but can also help us to protect it in an invaluable way.”
