Large Mission Class
OKEANOS (Oversize Kite-craft for Exploration and Astronautics in the Outer Solar system) was a proposed mission concept to Trojan asteroids, which share Jupiter's orbit, using a hybrid solar sail for propulsion; the sail was planned to be covered with thin solar panels to power an ion engine. In situ analysis of the collected samples would have been performed by either direct contact or using a lander carrying a high-resolution mass spectrometer. A sample-return to Earth was an option under study.[4]
OKEANOS was a finalist for Japan's Institute of Space and Astronautical Science (ISAS)' 2nd Large Mission Class to be launched in 2026,[2][5][6] and possibly return Trojan asteroid samples to Earth in the 2050s.[6][7] The winning mission was LiteBIRD.
