Though data from orbiters have suggested presence of ទឹក ice, the exploration of តាមច័ន្ទគតិ craters in the polar regions of moon has not been possible due to the absence of suitable technology to power តាមច័ន្ទគតិ 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 ភព’) commissioned by European អវកាស Agency is ready to develop prototypes that would provide laser power to these rovers in an effort to explore evidence of existence of ទឹក in these craters.
ព្រះច័ន្ទ វាមិនវិលតាមអ័ក្សរបស់វាទេ ដោយសារវាវិលជុំវិញផែនដី ដូច្នេះផ្នែកម្ខាងទៀតនៃព្រះច័ន្ទមិនអាចមើលឃើញពីផែនដីឡើយ ប៉ុន្តែភាគីទាំងពីរទទួលបានពន្លឺព្រះអាទិត្យពីរសប្តាហ៍ អមដោយយប់ពីរសប្តាហ៍។
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 តាមច័ន្ទគតិ orbiters of ESA, ISRO និង អង្គការណាសា have shown that these permanently shadowed areas are rich in hydrogen, suggestive of presence of ទឹក (ice) in these craters. This information is of interest for science as well as a local source of ‘ទឹក 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 តាមច័ន្ទគតិ 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.
ការពិចារណាមួយគឺការមានរ៉ូវដើរដោយថាមពលនុយក្លេអ៊ែរ ប៉ុន្តែវាត្រូវបានគេរកឃើញថាមិនស័ក្តិសមសម្រាប់ការរុករកទឹកកក។
គម្រោងនេះបានលើកឡើងពីរបាយការណ៍នៃការប្រើប្រាស់ឡាស៊ែរដើម្បីផ្តល់ថាមពលដល់យន្តហោះគ្មានមនុស្សបើកដើម្បីរក្សាវាឱ្យនៅខ្ពស់ក្នុងរយៈពេលយូរជាងនេះ។ ហ្វីលីព (‘Powering rovers by High Intensity Laser Induction on ភព’) was commissioned by European អវកាស Agency to design a complete ថាមពលឡាស៊ែរ បេសកកម្មរុករក។
The PHILIP project is completed now and the ESA is one step closer to powering តាមច័ន្ទគតិ rovers with lasers to explore the super cold dark រណ្ដៅតាមច័ន្ទគតិ នៅជិតបង្គោល។
ESA would now begin to develop prototypes for exploring the dark craters that would provide evidence for confirmation of the presence of ទឹក (ice) leading to realisation of human dream to inhabit this satellite.
