在太阳系中发现了被冰覆盖的海洋。在地球上，这样的环境是已知的庇护生命。在一些海洋世界，如欧罗巴，一个活跃的循环冰壳和岩石的独特组合，可能是岩浆内部可能会产生一个适合生命的地球化学系统，与地球上的冰冻圈没有太大的不同，在那里，冰可以作为一个合适的界面沿着融化和冻结提供化学梯度，生命可以利用。进入海洋世界的冰下海洋要求开发自主水下航行器（AUV）探测这些水体。寻找生命最有成效的地方将是由物理和化学梯度提供的能源，这可能不一定发生在低温机器人的突破位置。这意味着使用移动的平台进行探索，而这反过来又由于极其有限的带宽和长达数小时的往返传输延迟，必须是一个自主平台。这是海洋世界生命搜寻计划的最后一步。一个智能的水下机器人探测器，可以在冰封的海洋中旅行;识别生物活动的迹象;回家，获取和分析样本;并返回对接站（低温机器人“母舰”）上传数据和充电，是寻找地球外生命的强大工具。
Ice-covered oceans are found across the Solar System. On Earth, such environments are known to harbor life. On some Ocean Worlds such as Europa, the unique combination of an actively recycled ice shell and rocky, possibly magmatic interior may give rise to a geochemical system suitable to life and not so terribly different from the terrestrial cryosphere, where the ice may act as a suitable interface along which melt and freeze provide chemical gradients of which life can take advantage. The entry into sub-ice oceans of Ocean Worlds calls for the development of autonomous underwater vehicle (AUV) rovers to explore these water bodies. The most fruitful places to search for life will be at energy sources provided by physical and chemical gradients, which may not necessarily occur at the break-through location of a cryobot. This implies exploration using a mobile platform, and this in turn–due to extremely limited bandwidth and hours-long round-trip transmission delay–must be an autonomous platform. This forms the final step of an Ocean Worlds life search program. An intelligent underwater robotic explorer which can travel in an icecovered ocean; identify signs of biological activity; home in on, acquire, and analyze samples; and return to a docking station (the cryobot “mothership”) to upload data and recharge is a powerful tool in the search for life off Earth.
