SENER WILL LEAD THE DESIGN AND MANUFACTURE OF THE SPACE CAPSULE THAT WILL VISIT A PRISTINE COMET

Marco Stanghini, Head of Business Development & Marketing (OHB-I), and Augusto Caramagno, Director of Institutional Space (Sener), sealing the agreement.

The Sener engineering and technology group has been selected to lead the design and manufacture of the probe for the Comet Interceptor space science mission of the European Space Agency (ESA), in cooperation with the Japanese Space Agency (JAXA). More specifically, Sener has signed a contract with OHB Italia, which leads the mission and the production of its spacecraft. As the main contractor for the design and construction of the space probe – which will be carried from OHB Italia’s spacecraft – Sener will lead an industrial consortium of more than 8 companies from 6 countries, experts in the field of aerospace, such as OHB Italia, SAFT France, MSC Canada, Euro-Composites Luxembourg, and Spain’s Iberespacio.

The mission will be launched in 2029 with the aim of visiting, for the first time in the history of space exploration, a pristine comet, meaning its physical and chemical properties have been unchanged since its birth due to never having approached the Sun.

The target will be a celestial body probably originating in the Oort cloud, a structure located at the limits of the solar system, where fluctuations caused by gravitational forces occasionally hurl some object toward the Sun, making it a periodic comet that has not yet completed an orbit. The Sener capsule will measure just over half a metre in diameter, just under one metre in height and weigh approximately 40 kg.

It will be carried by the main spacecraft from OHB Italia, responsible for the mission, and separate to perform an approach within a few hundred kilometres of the comet’s nucleus, making scientific observations of plasma, magnetism and radiation in various visible and infrared spectra, while the main spacecraft remains safe a much further distance away.

In addition to the probe, Sener provides other key elements of the mission: Several scientific instruments both on the Sener probe and on the OHB main spacecraft, in cooperation with Instituto Astrofísico de Andalucía; the communication antennas which permit the commanding of the main spacecraft from Ground and the downloading of the scientific data gathered in the mission; and the separation mechanisms of the probe from the main spacecraft, designed and manufactured in Poland by Sener.
