Mathaka a thata a pheletsong ea sebaka
Ho ea ka liphuputso tse entsoeng ke litsebi tsa baeloji ea lintho tse nyenyane tse phelang Univesithing ea Amerika ea Maryland, har’a tse ling, sebaka sena sa stratosphere se na le li-extremophiles tse khonang ho mamella serame se feteletseng le ho hlaseloa ke mahlaseli a kotsi a ultraviolet ’me e le moeli o hōle ka ho fetisisa oa bophelo ba lefatše. Bo-rasaense ba batla ho hlahisa "Atlas of Stratospheric Microbes" e tla thathamisa likokoana-hloko tse phelang libakeng tse phahameng.
Lithuto tsa likokoana-hloko tse maemong a holimo a sepakapaka li 'nile tsa etsoa ho tloha ka bo-30. E mong oa bo-pula-maliboho ba bona o ne a tumme Charles Lindbergheo, hammoho le mosali oa hae, ba ileng ba hlahloba lisampole tsa sepakapaka. Sehlopha sa bona se fumane ho bona, har'a ba bang, likokoana-hloko tsa li-fungus le peō ea limela.
Lilemong tsa bo-70, lithuto tsa pele tsa baeloji tsa stratosphere li ile tsa etsoa, haholo-holo Europe le Soviet Union. Hajoale baeloji ea atmospheric e ntse e ithutoa, ho kenyeletsoa ka morero oa NASA o bitsoang PHAHAMA (). Joalokaha bo-rasaense ba hlokomela, maemo a feteletseng a Lefatše la stratosphere a tšoana le a sepakapaka sa Martian, kahoo thuto ea bophelo ba stratospheric e ka thusa ho khetholla "lisele" tse fapaneng ka ntle ho polanete ea rona.

Ka bomalimabe, ha ho na mananeo a mangata a lipatlisiso a reretsoeng lintho tse phelang sepakapakeng. Ho na le mathata ka sena, hobane mahloriso a likokoana-hloko ka palo ea yuniti e tlase haholo moo. Sebakeng se thata, se omeletseng, se batang, maemong a moea o sa fumaneheng haholo le mahlaseli a mahlaseli a kotsi, likokoana-hloko li tlameha ho hlahisa mekhoa ea ho iphelisa ea li-extremophile. Hangata libaktheria le li-fungus li shoella moo, empa tse ling li phela ka ho etsa li-spores tse sireletsang liphatsa tsa lefutso.

Mekhatlo ea sepakapaka, ho kenyeletsoa le NASA, hajoale e hlokolosi hore e se ke ea pepesetsa mafatše a mang ho likokoana-hloko tse phelang lefatšeng, kahoo ho nkoa mehato ea ho itšireletsa pele e kenya ntho leha e le efe tseleng. Maemong a mangata, likokoana-hloko ha li na monyetla oa ho pholoha ho phatloha ha libomo tsa cosmic ray. Empa likokoana-hloko tsa stratospheric li bontša hore tse ling li ka li etsa. Ke ’nete hore ke habohlokoa ho hopola hore ho pholoha ha ho tšoane le ho atleha bophelong. Taba ea hore sebōpuoa se phela sepakapakeng ’me, ka mohlala, se fihla Mars ha se bolele hore se ka hōla le ho ikatisa moo.
Na sena se hlile se joalo - potso ena e ka arajoa ke lithuto tse qaqileng tsa lintho tse phelang tsa stratospheric.
