I-PHILIP: I-Laser-Powered Rover Yokuhlola Ama-Super-Cold Lunar Crater Amanzi

Nakuba idatha evela ama-orbiters baye baphakamisa ukuba khona kwe amanzi iqhwa, ukuhlola kwe inyanga ama-craters ezindaweni ezipholile zenyanga akwenzekanga ngenxa yokungabikho kobuchwepheshe obufanele bokusebenza inyanga ama-rover ezindaweni ezimnyama, ezibandayo kakhulu ezinezinga lokushisa elingu-240°C. Iphrojekthi PHILIP ('Powering rovers by High Intensity Laser Induction on amaplanethi') egunyazwe ngabaseYurophu Space I-Ejensi isilungele ukwenza ama-prototypes azohlinzeka ngamandla e-laser kulawa ma-rover emzamweni wokuhlola ubufakazi bokuba khona kwe amanzi kulemigodi.

Moon ayijikelezi eksisini yayo njengoba izungeza umhlaba yingakho olunye uhlangothi lwenyanga lungabonakali emhlabeni kodwa izinhlangothi zombili zithola amasonto amabili okukhanya kwelanga okulandelwa amasonto amabili ebusuku.

Nokho, kunezindawo ezishone emigodini esezindaweni ezimaphakathi zenyanga ezingakutholi ukukhanya kwelanga ngenxa yokuthi i-engeli ephansi yokukhanya kwelanga eshiya ingaphakathi lemigodi emthunzini unomphela. Lobu bumnyama obungapheli kuma-polar craters buwenza abande kakhulu ebangeni elingu -240°C elihambisana cishe no-30 Kelvin okungukuthi ama-degree angu-30 ngaphezu kweziro ngokuphelele. Idatha etholwe ku- inyanga ama-orbiters kwe-ESA, ISRO futhi NASA baye babonisa ukuthi lezi zindawo ezinomthunzi unomphela zicebile nge-hydrogen, okusikisela ukuba khona kwe amanzi (iqhwa) kule migodi. Lolu lwazi luyintshisekelo yesayensi kanye nomthombo wendawo 'amanzi kanye ne-oxygen' yendawo yokuhlala yenyanga ezayo. Ngakho-ke, kunesidingo se-rover engase yehlele kuma-craters anjalo, ibhoboze futhi ilethe isampula ukuze ihlolwe ukuze kuqinisekiswe ukuba khona kweqhwa lapho. Inikezwe inyanga ama-rover ngokuvamile asebenzisa amandla elanga, lokhu akukafinyelelwa kuze kube manje ngoba akukwazanga ukuqinisekisa ukunikezwa kwamandla kuma-rovers ngenkathi kuhlolwa amanye alawa ma-crater amnyama.

Okunye obekucatshangwa ukuthi kube namarover anamandla enuzi kodwa lokhu kwatholakala ukuthi akufanelekile ukuhlola iqhwa.

Ngokuthatha inkomba emibikweni yokusetshenziswa kwe-laser ukwenza ama-drones aphehla amandla ukuze awagcine ephezulu isikhathi eside, iphrojekthi UFILIPI ('I-Powering rovers nge-High Intensity Laser Induction on amaplanethi') yagunyazwa ngabaseYurophu Space I-ejensi yokuklama okuphelele i-laser-powered umsebenzi wokuhlola.

Iphrojekthi ye-PHILIP isiqediwe manje futhi i-ESA iyisinyathelo esisodwa sokusondela ekunikezeni amandla inyanga ama-rover anama-laser ukuhlola ubumnyama obubanda kakhulu imigodi yenyanga eduze kwezigxobo.

I-ESA manje isizoqala ukwenza ama-prototypes okuhlola ama-craters amnyama azonikeza ubufakazi bokuqinisekisa ukuba khona amanzi (iqhwa) okuholela ekufezekeni kwephupho lomuntu lokuhlala kule sathelayithi.
