Though data from orbiters have suggested presence of ujë ice, the exploration of si hënëz craters in the polar regions of moon has not been possible due to the absence of suitable technology to power si hënëz 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 Hapësirë Agency is ready to develop prototypes that would provide laser power to these rovers in an effort to explore evidence of existence of ujë in these craters.
Hënë nuk rrotullohet rreth boshtit të saj ndërsa rrotullohet rreth tokës, prandaj ana tjetër e hënës nuk është kurrë e dukshme nga toka, por të dyja palët marrin dy javë rreze dielli të ndjekura nga dy javë natë.
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 si hënëz orbiters of ESA, ISRO NASA have shown that these permanently shadowed areas are rich in hydrogen, suggestive of presence of ujë (ice) in these craters. This information is of interest for science as well as a local source of ‘ujë 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 si hënëz 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.
Një konsideratë ishte që të kishim rovera me energji bërthamore, por kjo u gjet të ishte e papërshtatshme për eksplorimin e akullit.
Duke marrë shkas nga raportet e përdorimit të lazerit për të fuqizuar dronët për t'i mbajtur ata lart për një kohëzgjatje më të gjatë, projekti FILIPI (‘Powering rovers by High Intensity Laser Induction on Planets’) was commissioned by European Hapësirë Agency to design a complete me energji lazer misioni i eksplorimit.
The PHILIP project is completed now and the ESA is one step closer to powering si hënëz rovers with lasers to explore the super cold dark krateret hënore pranë poleve.
ESA would now begin to develop prototypes for exploring the dark craters that would provide evidence for confirmation of the presence of ujë (ice) leading to realisation of human dream to inhabit this satellite.
