Marka la eego cutubkan ku saabsan Tardigrades-ka goormee ayay ahayd markii ugu horeysay ee aan u dirno hawada sare?
Context:Xayawaanka loo yaqaano Tardigrades-ka ayaa ah xayawaankii ugu horeeyay ee la ogaado in uu badbaado kadib markii uu soo gaaro meel bannaan. Bishii Sebtember 2007, tardigrades biyo la'aan ah ayaa loo qaaday dhulka hoose ee dhulka hoostiisa ee FOTON-M3 howlgalka xamuulka astrobiology BIOPAN. Toban cisho, kooxo dad ah oo hilib qaboojiyeyaal ah qaarkoodna biyo la'aan ayaa kujirey qaboowga adag ee hawada sare, ama shucaaca UV-ga ee qorraxda. Dib ugu noqoshada dhulka, in ka badan 68% maadooyinka laga ilaaliyay shucaaca UV-ga ee qorraxda ayaa dib loo soo nooleeyay 30 daqiiqo gudahood ka dib dib markii dib loo nadiifiyey, in kasta oo dhimashada dambe ay sare u kacday; qaar badan oo ka mid ah kuwan waxay soo saareen uurjiifyo nool. Taas bedelkeeda, tijaabooyinka la waraabiyay ee la soo bandhigay saamaynta isku dhafan ee hawada iyo shucaaca UV ee qorraxda oo buuxa ayaa si weyn hoos ugu dhigay badbaadada, iyadoo kaliya seddex maado oo Milnesium tardigradum ah ay badbaadeen. Sidoo kale, waxaa la ogaaday in hawada banaan aysan saameyn weyn ku yeelan karin ukunta R. coronifer ama M. tardigradum. Si kastaba ha noqotee, M. tardigradum oo ay soo gaareen shucaaca UV waxay lahaayeen heerka ukunta oo hooseeya. Bishii Maajo 2011, saynisyahano Talyaani ah ayaa tardigrades u diray Saldhigga Caalamiga ah ee Hawada oo ay weheliyaan extremophiles-ka STS-134, duulimaadkii ugu dambeeyay ee Space Shuttle Endeavour. Waxay ku soo gabagabeeyeen in cufnaanta yar iyo shucaaca cosmic "aaney si weyn u saameynayn badbaadada tardigrades duulimaadka, waxayna sheegeen in tardigrades ay matalaan xayawaan waxtar u leh cilmi baarista hawada sare". Bishii Nofeembar 2011, waxay ka mid ahaayeen noolaha ay soo direen Ururka Planetary Society ee fadhigiisu yahay Mareykanka oo ku jiray howlgalkii Fobos-Grunt ee Ruushka ee Tijaabada Duulimaadka Caalamiga ah ee ku nool Phobos; si kastaba ha noqotee, bilowgu wuu fashilmay. Bishii Agoosto 2019, saynisyahannadu waxay soo sheegeen in kaabsal ay ku jiraan tardigrades oo ku jira xaalad cryptobiotic ah ay u badan tahay inuu in muddo ah ka badbaaday Dayaxa ka dib markii bishii Abriil 2019 ay ku burburtay Beresheet, oo ah dayax-gacmeedkii dayaxa ee Israa'iil oo fashilmay, laakiin bishii Maajo 2021 ayaa la sheegay inaysan u badnayn inay ka badbaadeen saameynta.
Hawlgalkii FOTON-M3 bishii September ee sanadkii 2007 ayaa waxa uu ahaa markii ugu horeysay ee Tardigrades-ka ay soo baxaan xaalada adag ee banaanka ee hawada sare.
