rock ice的意思|示意

NASA crashed an empty rock booster into the moon to see if water-ice crystals were at the South Pole.

NASA将一枚空岩助推器撞向月球，以探测在月球南极是否存在水冰晶体。

Subtle differences in Titan's pull on Cassini suggest that the materials inside the moon are a mix of ice and rock with no clearly defined rocky layers.

泰坦星对卡西尼号牵引力的细微变化表明，该星球内部为冰和岩石的混合物，且没有明晰的岩石分界线。

But a new look at Titan's insides reveals even more oddities: Beneath the brittle crust of ice lies a layer of slush. Deeper still is an underground ocean over a solid core of rock and ice.

但最近对泰坦内部的一项新研究却揭开了这颗奇异星球更为怪诞的一面：脆弱的甲烷冰地表之下，覆盖着一层冰泥，更深处依然是一个地下海洋，最中间是冰和岩石并存的固态核心。

The rocks were wet on the side that faced the sun and glazed with ice in the shade; between one rock spike and the next were pockets of wet snow where we sank up to our shoulders.

旁边面对太阳的岩石潮湿，阴凉处的冰雪显得十分光滑；岩峰与岩峰之间是一直没到我们的肩部的潮湿的雪穴。

The rings—there are thousands—are made up of billions of ice and rock particles, thought to be pieces of comets, asteroids, or shattered moons

这些环，有成千上万个，是由数十亿个冰和岩石的粒子所组成，这些粒子被认为是彗星、小行星和粉碎卫星的碎片。

Giant chunks of rock and ice soar through its cold expanse with no destination, and no set path.

巨形的岩石和冰块漫无目的，毫无规律地穿行在这片冷寂的广漠空间。
