这些楔形机器人非常小巧，长度仅约 12 厘米，将携带名为“钻冰机器人（cryobot）”的装置，利用核能融化冰层，深入木卫二等星球的冰壳之下。 美国计划派遣数十个机器人，将以团队协作的方式，从不同方向对同一区域进行探测，减少观测数据的误差。

Their wedge-shaped bodies are about 12 centimeters long. A device called a “cryobot” will transport the robots beneath the thick ice shells of these moons, using nuclear energy to melt the ice.

The current prototypes measure 16.5 inches (42cm) in length and weigh about five pounds (2.3kg). Engineers aim to reduce their size by two-thirds, making them roughly the size of a mobile phone. The ...

Dr Schaler added: “The concept relies on a cryobot that is designed to access the subsurface ocean by melting or boring through the ice shell, but has limited mobility once it reaches and ...
