Masana kimiyya daga Sandia National Laboratories sun kaddamar da aikin balloon mai amfani da hasken rana wanda ke dauke da makirufo zuwa wani yanki na yanayin duniya da ake kira stratosphere.
Manufar ita ce nazarin yanayin sauti a wannan yanki. Duk da haka, abin da suka gano ya ba masana kimiyya mamaki. Sun yi rikodin sauti mai tsayi a cikin yanayin duniya wanda ba za a iya gane su ba.
The m surutai sun bar masana cikin rudani kuma har zuwa yanzu, babu wani bayani game da waɗannan sauti masu ban mamaki. Domin galibin wannan yanki yana cikin kwanciyar hankali kuma ba shi da guguwa, tashin hankali, da zirga-zirgar jiragen sama na kasuwanci, makirufo a cikin wannan yanayin na iya sauraren sautin yanayi da na mutum.
Koyaya, makirufo a cikin binciken ya ɗauki wasu kararraki masu ban mamaki waɗanda ke maimaita ƴan lokuta a cikin awa ɗaya. Har yanzu ba a gano asalinsu ba.
An yi rikodin sautunan a cikin kewayon infrasound, ma'ana sun kasance a mitoci na 20 hertz (Hz) da ƙasa, ƙasa da kewayon kunnen ɗan adam. A cikin wata sanarwa da Daniel Bowman na Sandia National Laboratories ya fitar, ya ce "Akwai alamun siginonin infrasound masu ban mamaki da ke faruwa a wasu lokuta a cikin sa'a guda a kan wasu jirage, amma ba a san tushen wadannan ba."
Bowman da abokan aikinsa sun yi amfani da micro barometers, waɗanda asalinsu an ƙirƙira su ne don sa ido kan tsaunuka masu aman wuta kuma suna da ikon gano ƙaramar ƙararrawar ƙararrawa, don tattara bayanan sauti daga stratosphere. Micro barometers sun gano siginonin infrared da aka maimaita ba tare da bayyana su ba baya ga abubuwan da ake tsammani na halitta da na mutum.
Balloon da Bowman da abokan aikinsa suka ƙera aka ɗaga na'urorin a sama. Balloons, waɗanda ke da diamita daga ƙafa 20 zuwa 23 (mita 6 zuwa 7), an yi su ne da kayan gama-gari kuma marasa tsada. Waɗannan na'urori masu sauƙi na yaudara, waɗanda hasken rana ke amfani da su, sun sami damar kaiwa tsayin tsayin ƙafafu 70,000 (mil 13.3) sama da ƙasa.
Bowman ya ce "Balloon mu manyan buhunan robobi ne masu dauke da kurar gawayi a ciki don sanya su duhu," in ji Bowman. “Muna gina su ta amfani da robobin fenti daga kantin kayan masarufi, tef ɗin jigilar kaya, da foda na gawayi daga shagunan samar da kayan aikin pyrotechnic. Lokacin da rana ta haskaka a kan balloons masu duhu, iskan da ke ciki ya yi zafi kuma ya zama mai armashi."
Bowman ya yi bayanin cewa wutar lantarki mai amfani da hasken rana ta isa ta tura balloons daga saman duniya zuwa mashigin. An sanya idanu kan balloon ta hanyar amfani da GPS bayan harba su, wani abu da tawagar ta yi domin sau da yawa balloon na iya tashi sama da daruruwan kilomita da kuma sauka a wurare masu wahala a duniya.
Bugu da ƙari kuma, kamar yadda al'amuran kwanan nan suka nuna, balloons na bincike na iya rikicewa don wasu abubuwa, suna haifar da damuwa mai haɗari. Ana iya amfani da balloons masu amfani da hasken rana irin wannan don yin nazarin asirai har ma daga doron duniya, ban da taimakawa wajen bincikar waɗannan sautin da ba su dace ba.
Irin waɗannan motocin a halin yanzu ana gwada su don gano ko za a iya haɗa su da wani jirgin sama na Venus don lura da girgizar ƙasa da tashin dutse ta cikin kauri. Balloons na robotic na iya zazzagewa cikin sararin sama na “Mugunyar tagwayen Duniya,” wanda yake sama da yanayin zafi mai tsananin zafi da matsa lamba yana binciken yanayin sa mai kauri da gajimare na sulfuric acid.
