Note - Deadline for submission has passed This Announcement of Opportunity (AO) solicits proposals of scientific investigations for the Solar Orbiter mission. Solar Orbiter is the next solar-heliospheric mission in the Science Programme of the European Space Agency (ESA). It has recently been redefined as part of a joint ESA-NASA programme called Heliophysical Explorers that comprises ESA's Solar Orbiter and NASA's Solar Sentinels as a highly synergetic programme. The Solar Orbiter mission is devoted to solar and heliospheric physics. It will be carried out as an ESA-led mission open to the worldwide science community.
