NASA考虑在火星上建造冰屋供早期定居者使用

NASA兰利中心研究人员揭示了最新的设计理念,利用丰富的火星资源-水,建造冰屋,供首批登陆火星的人类探险者居住。兰利中心的冰屋背后的想法是利用火星资源建造一个栖息地,保护居民免受放射元素和有害的星系宇宙射线侵害,最大限度地降低从地球运输原材料的成本。

这种冰之家由空间探索建筑(SEArch)和云建筑办公室(Clouds AO)团队合作开发,在美国宇航局3D打印居住挑战设计大赛第一轮获得一等奖,是一个健全的工程解决方案,NASA宣布它是目前早期火星前哨基地最佳解决方案,因为它提供了几个优点。

冰屋的主要特点之一是它的充气外壳,其中的蜂窝袋可可以储存从火星上开采的水,并且使用它作为宇宙射线的屏蔽材料。此外,还有可能将水转化为火星上升车的燃料。

其次,冰之家的轻量化设计为早期殖民者提供了实用的优势,因为它可以用简单的机器人轻松地运输和部署,然后使用地球运输过来的工程机械挖掘地下仓库。

最后,冰也将允许自然光通过,这对维持心理健康和士气至关重要。

Curiosity Rover hits JACKPOT in search for ALIEN life on Mars

NASA’S Curiosity Rover has hit the “jackpot” in the search for alien life on Mars, researchers have sensationally claimed.

Scientists believe that the Curiosity Rover has collected very promising data in the search for life elsewhere in the universe.The machine, which has been on the Red Planet since August 2012, has collected samples from a crater which shows convincing signs that Mars could home life or once did.

Samples from a spot known as the Gale Crater shows that there is an abundance of mineral deposits which provide evidence that there was once water and that environmental conditions are suitable for life.

John Grotzinger, a geologist from the California Institute of Technology, was speaking at the annual American Geophysical Union in San Francisco when he said: “We see all of the properties in place that we really like to associate with habitability.

“There’s nothing extreme here. This is all good for habitability over time.”The Curiosity Rover is taking samples every 25 metres along the Gale Crater – the lowest point on Mars which has led scientists to believe that there was once a great lake there.

The upper layers of the crater contain a large amount of oxidising hematite, which suggests that it was once acidic.However, the crater is, according to Mr Grotzinger, “acidic but never super acidic. It’s totally the kind of environment where an acidophilic organism could enjoy it.”

The Rover has also identified a heap of minerals and boron, which on Earth is associated with the formation of RNA – one of the essential building blocks of life along with DNA and proteins.
Mr Grotzinger added: “We are seeing chemical complexity indicating a long, interactive history with the water. The more complicated the chemistry is, the better it is for habitability.“The boron, hematite and clay minerals underline the mobility of elements and electrons, and that is good for life.”
