OKEANOS (Oversize Kite-craft for Exploration and Astronautics in the Outer Solar System) is a proposed mission concept to Trojan asteroids, which share Jupiter's orbit, using a hybrid solar sail for propulsion; the sail is covered with thin solar panels to power an ion engine. In-situ analysis of the collected samples would be performed by either direct contact or using a lander carrying a high-resolution mass spectrometer. A sample-return to Earth is an option under study.

  • OKEANOS(Oversize Kite-craft for Exploration and AstroNautics in the Outer Solar system、オケアノス - 外惑星領域探査と宇宙航法のための特大凧型探査機)は、2020年代後半の打上げ実現を目指して検討中の日本の工学ミッション。小型ソーラー電力セイル実証機「IKAROS」で実証されたソーラー電力セイルと高比推力のイオンエンジンを組み合わせて推進力として木星圏を目指す。300億円という戦略的中型計画の予算の制約から「はやぶさ」と同じく工学ミッションとして提案されており、次号機以降で確実に理学成果を上げるため、理学観測を含む探査シナリオを実証することが本ミッションの目的となる。
  • 태양계 외부 탐사와 천문학을 위한 대형 키트크래프트(Outsized Kite-craft for Exploration and Astronautics in the Outer Solar System), 약칭 OKEANOS는 목성 트로이군을 탐사하는 JAXA의 탐사선이다. 기술을 사용해 추진하며, 목적은 목성 트로이군의 사진을 촬영하고 구성 성분을 분석한 뒤 지구로 샘플을 보내는 것이다. 특이사항으로는 장기 프로젝트로, 2026년 발사되어 2050년대 귀환한다.
  • OKEANOS (Oversize Kite-craft for Exploration and Astronautics in the Outer Solar System) és un concepte de missió proposat per als asteroides troians, els quals comparteixen l'òrbita de Júpiter, utilitzant una vela solar híbrida per propulsió; la vela està coberta amb panells solars prims per alimentar un Motor iònic. L'anàlisi in-situ de les mostres recollides es duria a terme mitjançant un contacte directe o mitjançant un mòdul d'aterratge amb un espectròmetre de masses d'alta resolució. Una mostra de retorn a la Terra és una opció en estudi.
  • OKEANOS (Out sized Kitecraft for Exploration and AstroNautics in the Outer Solar System) est une mission spatiale japonaise en cours d'évaluation dont l'objectif est d'une part de tester de nouvelles techniques et d'autre part l'étude des astéroïdes troyens de Jupiter. La sonde spatiale développée dans le cadre de ce projet, atterrit sur le sol d'un astéroïde pour effectuer des analyses in situ des échantillons de son sol. La sonde spatiale utilise une voile solaire de 2 500 m² couverte de cellules photovoltaïques en s'appuyant sur la technologie expérimentée avec succès par la mission IKAROS. La propulsion est assurée à la fois par la pression de rayonnement des photons sur la voile solaire et par des moteurs ioniques. La mission est lancée vers 2026 et arrive à sa destination une dizaine
