奇观:火星上的这三年

奇观:火星上的这三年

Three Years on Mars

  火星上的三年

  1、Feel for the Land

  The two rovers, Spirit and Opportunity, were meant to last 92 days but are still going strong.  Spirit has encountered some spectacular examples of basaltic rocks, formed by volcanic processes, with striking textures.

  火星上的感觉

  “勇气”号和“机遇”号在火星漫游了92天,但是现在它们似乎精力还很旺盛。“勇气”号发现了火星上火山爆发形成的玄武岩。

2、Blueberries

  When some scientists first saw these strange beads of hematite photographed with Opportunity's microscopic imager, the spheres seemed like "blueberries" embedded in a "muffin" of martian soil.

  火星“蓝莓”

  科学家们刚看到“机遇”号从火星发回的赤铁矿珠子照片时,他们还以为这是火星土壤里生长的“蓝莓”。

3、Dazzling Dunes

  As Opportunity came to the bottom of Endurance crater, it found these dune crests in false-color, seeing a blue tint from hematite-containing spherules ("blueberries") that accumulate on flat surfaces.

  眩目的“沙丘”

  当“机遇”号来到火星Endurance坑时,它发现了这些令人目眩的“沙丘”,“沙丘”是赤铁矿珠子形成的。

4、Micro-landscape

Spirit used its microscopic imager to capture this spectacular, jagged mini-landscape on a rock called "GongGong." Measuring only 3 cm across, this surface records two of the most important and violent forces in the history of Mars: volcanoes and wind.

  显微世界

  “勇气”号用显微镜拍摄的“GongGong”岩石的结构图片。这种岩石是火星上风和火山作用的结果。

6、Hints at Water

  Opportunity's view of fine layers on a ledge in Erebus crater shows a diverse range of primary and secondary sedimentary textures formed billions of years ago. These structures likely resulted from an interplay between wind and water processes.

  水的线索

  “机遇”号在Erebus坑拍摄的初级和次级岩石断层照片,这些断层有10几亿年的历史,是火星上风和水作用的结果。

7、A Textured Land

  A spectacular field of Martian sand ripples separates Spirit from the slopes of Husband Hill. Spirit captured this view while the sun was low in the sky late in the afternoon. Because of the low-angle lighting, images like this provide superb views of subtle textures in the topography both near and far.

  远近景观分明

  在太阳快要落山的时候,“勇气”号在Husband山坡处拍摄了火星沙地照片,在较暗的光线下仍然能看到远近沙地层次分明的布局。

8、Cape Verde

  Cape Verdeand other features at Victoria crater were named in honor of areas on Earth explored by Ferdinand Magellan in the 1500s.

  火星佛得角

  火星上的佛得角、维多利亚坑都是为了纪念16世纪麦哲伦航海而命名的。

9、Martian Sunset

  Spirit sent back this stunning shot of the sun sinking below the rim of Gusev crater.

  火星日落

  “勇气”号在火星Gusev坑附近拍摄的壮观的火星日落景观。
