  • Jake Matijevic (or Jake M) is a pyramidal rock on the surface of Aeolis Palus, between Peace Vallis and Aeolis Mons ("Mount Sharp"), in Gale crater on the planet Mars. The approximate site coordinates are: 4°35′S 137°26′E / 4.59°S 137.44°E. The rock was encountered by the Curiosity rover on the way from Bradbury Landing to Glenelg Intrigue in September 2012 and measures about 25 cm (9.8 in) height and 40 cm (16 in) width. The rock was named by NASA after Jacob Matijevic (1947–2012), a mathematician-turned-rover-engineer, who played a critical role in the design of the six-wheeled rover, but died just days after the Curiosity rover landed in August 2012. Matijevic was the surface operations systems chief engineer for the Mars Science Laboratory Project and the project's Curiosity rover. He was also a leading engineer for all of the previous NASA Mars rovers including Sojourner, Spirit and Opportunity. The rover team determined the rock to be a suitable target for the first use of Curiosity's contact instruments, the Mars Hand Lens Imager (MAHLI) and the Alpha particle X-ray spectrometer (APXS). Analytical studies, performed on the rock by the Curiosity rover in October 2012, suggest the Jake M rock is an igneous rock but found to be high in elements consistent with feldspar, such as sodium, aluminum and potassium, and lower concentrations of magnesium, iron and nickel than other such rocks previously found on Mars. The mineral content and elemental abundance indicates Jake M rock may be a mugearite, a sodium rich oligoclase-bearing basaltic trachyandesite. Igneous rocks similar to the Jake M rock are well known but occur rarely on Earth. On Earth, such rocks form when magma, usually found in volcanoes, rises to the surface, cools and partially solidifies with certain chemical elements, while the warmer liquid magma portion becomes enriched with the left-behind elements. By remarkable coincidence, the Martian locality Glenelg is also the name of a small settlement in north-west Scotland that is 25 km (16 mi) east of type locality for mugearite at Mugeary on the island of Skye. The Jake M rock is a ventifact with a volcanic fabric. Its pyramidal shape was formed by eolian drifted grains of sand. The little cavities on its surface were formed by the blast-effect, which is caused by different flow dynamics at the micro-relief. On the surface one could see the marks of the main wind direction, by which Jake M was formed. On September 27, 2013, NASA scientists reported that Jake M rock was a mugearite and very similar to terrestrial mugearite rocks. (en)

  • 杰克·马蒂耶维奇(“Jake Matijevic”或“Jake M”)是火星埃奥利斯沼表面的一块金字塔形岩石,位于盖尔撞击坑内皮斯谷和埃俄利斯山(“夏普山”)之间,大致的位置坐标为:4°35′S 137°26′E / 4.59°S 137.44°E。 2012年9月,“好奇号”漫游车在从布雷德伯里着陆场前往格莱内尔格途中遇到了这块岩石,测量到它的高度和宽度分别约为25厘米(9.8英寸)和40厘米(16英寸)。。 该岩石由美国宇航局以“杰克·马蒂耶维奇”1947年-2012年)之名命名,他是一位数学家,后来转行成为火星车工程师,在六轮火星车设计中发挥了关键作用,但就在“好奇号”探测车于2012年8月着陆后数天,马蒂耶维奇就不幸离世。他是火星科学实验室项目及“好奇号”探测车地面操作系统总工程师,还是美国宇航局之前所有火星车,包括“旅居者号”、勇气号”和“机遇号”的首席工程师。 漫游车团队确认该岩石为首次使用“好奇号”接触式仪器-火星手部透镜成像仪和阿尔法粒子X射线光谱仪的合适目标。 2012年10月,“好奇号”探测车对该岩石进行的分析研究表明,杰克·马蒂耶维奇岩石是一种岩浆岩,但发现与长石一致的元素含量较高,如钠、铝和钾等,而镁、铁和镍的丰度却比以前在火星上发现的其他类似岩石要低。矿物含量和元素丰度表明,杰克·马蒂耶维奇岩石可能是一种橄榄粗安岩,一种富钠奥长石-夹杂玄武质的粗面安山岩(trachyandesite)。类似于杰克·马蒂耶维奇岩石的岩浆岩被众所周知,但在地球上很少出现。在地球上,此类岩石的形成,一般发现于从火山中涌出到表面的岩浆。岩浆冷却并部分固化了某些化学元素,而更多的元素则留在了炽热的液态岩浆中。非常巧合的是,火星上格莱内尔格地区也是苏格兰西北部一处小村庄的名称,该村庄就位于斯凯岛穆格里(Mugeary)农庄橄榄粗安岩典型地区以东25公里处。 杰克·马蒂耶维奇岩石是一种火山质地的风砺石,它的金字塔状外观形成于流沙颗粒的风蚀作用,其表面的小孔则是由细微起伏处不同流动动力引起的爆炸效应而成,在表面上可看到形成杰克·马蒂耶维奇岩石的主风向痕迹。2013年9月27日,美国宇航局的科学家报告说,杰克·马蒂耶维奇岩石是一种橄榄粗安岩,与地球上的橄榄粗安岩非常相似。 (zh)
