PHILIP:激光动力漫游车探索超冷月球陨石坑中的水

Though data from orbiters have suggested presence of water ice, the exploration of 太阴 craters in the polar regions of moon has not been possible due to the absence of suitable technology to power 太阴 rovers in the perpetually dark, super cold areas having a temperature of –240°C. The project PHILIP (‘Powering rovers by High Intensity Laser Induction on Planets’) commissioned by European Space Agency is ready to develop prototypes that would provide laser power to these rovers in an effort to explore evidence of existence of water in these craters.

Moon 当它围绕地球旋转时,它不绕其轴旋转,因此从地球上永远看不到月球的另一面,但两边都会收到两周的阳光,然后是两周的夜晚。

However, there are sunken areas in craters situated in the polar regions of moon that never receive sun-light because low angle of sunlight that leave the deep interiors of the craters in shadow forever. This perpetual darkness in the polar craters make them super cold in the range of –240°C corresponding roughly to about 30 Kelvin i.e. 30 degrees above absolute zero. The data received from the 太阴 orbiters of ESA, ISRO 美国航空航天局 have shown that these permanently shadowed areas are rich in hydrogen, suggestive of presence of (ice) in these craters. This information is of interest for science as well as a local source of ‘water and oxygen’ for future moon human habitation. Therefore, there is a need of a rover that could go down to such craters, drill and bring sample for testing to confirm presence of ice there. Given 太阴 rovers are usually solar powered, this has not been achieved so far because it has not been possible to ensure power supply to rovers while it explores some of these dark craters.

一个考虑是拥有核动力漫游车,但发现这不适合冰上探索。

该项目从使用激光为无人机提供动力以使其在空中保持更长的时间的报告中得到启发, PHILIP (“通过行星上的高强度激光感应为漫游车提供动力”)受欧洲航天局委托设计一个完整的 激光供电 探索任务。

The PHILIP project is completed now and the ESA is one step closer to powering 太阴 rovers with lasers to explore the super cold dark 月球陨石坑 两极附近。

ESA 现在将开始开发用于探索黑暗陨石坑的原型,这些原型将为确认水(冰)的存在提供证据,从而实现人类居住在这颗卫星上的梦想。
