Sener has been responsible for the mission’s low gain antenna, collaborating with companies from Spain, Portugal, Romania, France, Germany, the Netherlands, and Ireland.
The Hera mission of the European Space Agency (ESA), which was launched on Monday from Cape Canaveral (Florida), has included the participation of Sener, responsible for its low gain antenna or LGA (Low Gain Antenna). Hera is the first ESA planetary defence mission and will carry out a detailed study of the impact of the asteroid Dimorphos, the moon put into orbit of the binary asteroid system known as Didymos.
The objective of Hera is to demonstrate the reliability of kinetic deflection as a planetary defence technique. Through its approach, Hera will collect and expand crucial missing data on Didymos and its asteroid Dimorphos following NASA’s DART mission and its impact on the asteroid Dimorphos in 2022, which caused an alteration in its orbit.
The antenna provided by Sener will help establish the ship’s communication with the tracking stations on Earth to send scientific data. The company has extensive experience in the design of fixed and steerable antennas, used for communication with satellites in all Earth orbits, and for probes and observatories sent into deep space. In this way, it has participated, for example, in the development of the low-gain antenna for the BepiColombo mission.
