Mauna Loa

Mauna loa is the largest volcano in Hawaii at 4,170 meters above sea level. It is conical and rises from the bottom of the Pacific Ocean at a depth of 6,000 meters.

On October 30, 2012, NASA announced that curiosity's first analysis of soil samples from Mars showed that parts of the Martian soil were similar to the soil on the side of Mauna Kea, Hawaii.

It is the first time that curiosity has used its own chemical and mineral instruments to conduct mineralogical identification of soil samples taken from Mars' gale crater since its successful landing on Aug. 6, 2012.

This is also the first time that X-ray diffraction techniques have been used to analyze the soil of extrasolar objects.

The soil samples came from a "rock nest" of dust and gravel, sifting through more than 150 microns of sand, leaving only two components, dust and the more mars-like fine sand, scattered throughout the planet.

Mauna Loa is the largest volcano in Hawaii. It is 4170 meters above sea level and is conical. It rises from the bottom of the Pacific Ocean with a depth of 6,000 meters. It is more than 10,000 meters from the bottom of the sea to the top of the mountain, and is more than 1,000 meters higher than Mount Everest. Meter.

On October 30, 2012, NASA announced that the first analysis of the Martian soil samples by Curiosity revealed that part of the soil in Mars was similar to the soil on the side of the Mauna Kea volcano in Hawaii.

This is the first time that Curiosity has used its own chemical mineral instrument to carry out mineralogy identification of the ingested soil samples since the successful landing on the Martian Gael crater on August 6, 2012.

This is also the first time that X-ray diffraction technology has been used to analyze soils outside the Earth.

The soil sample comes from a pile of dust and gravel called “Rock Nest”. After filtering out more than 150 microns of sand, only the dust that is scattered throughout the planet and the fine sand with more Mars characteristics are left.

冒纳罗亚火山是夏威夷第一大火山，海拔4170米，呈圆锥形，是从水深6000米的太平洋底部耸立起来的，从海底到山顶高度超过一万米，比珠穆朗玛峰还高一千多米。

2012年10月30日，美国宇航局（NASA）宣布， 好奇号探测器对火星土壤样本的首次分析显示，火星部分土壤与夏威夷冒纳凯阿火山（Mauna Kea）侧面的土壤相似。

这是好奇号自美国东部时间2012年8月6日在火星盖尔陨石坑成功着陆后，首次用自带的化学矿物仪器对摄入的土壤样本进行矿物学鉴定。

这也是X射线衍射技术第一次用于分析地球以外星体的土壤。

土壤样本来自一片名为“岩巢”的灰尘和沙砾堆，筛选掉超过150微米的沙砾后，只剩下遍布于整个星球的灰尘和更具火星特色的细沙两种成分。
