This event is organized exclusively for guests invited by the scientific organizing committee. It is not open to the general public.
We will celebrate the 30th anniversary of the launch of the SoHO mission (Solar and Heliospheric Observatory) on December 10, 2025, on the Saclay plateau, Henri Moissan site, 17 Avenue des Sciences, 91400 Orsay (Amphitheater “Hervé Daniel”, Building HM2, see below).
The SoHO mission, jointly developed by ESA and NASA, with 12 instruments on board, dedicated to observing the Sun, from its innermost to its outermost layers, began its work in the spring of 1996. Since then, data has continued to arrive at the Goddard Space Center, and to be relayed at the MEDOC data center at IAS, on the Orsay campus. Hundreds of publications have resulted from the exploitation of this data, with strong involvement of scientific teams from CNRS and French universities. This was possible thanks to continuous support from CNES since the beginning of this 30 years space adventure.
We will meet for this event from 2:00 p.m. to 6:00 p.m. (provisional program below). The main scientific and technical results will be summarized for a non-specialist audience. The future of space solar physics will also be discussed. These presentations will be followed by a cocktail reception in the lobby of the Henri Moissan building, where scientific activities will brighten the end of the day.
The persons who have received an invitation can confirm their attendance or register by completing the following survey before September 30, 2025:
