Poyasnenie: Est' li na Marse metan i otkuda on beretsya? Problema stanovitsya vse bolee zaputannoi. Orbital'nyi apparat dlya issledovaniya malyh gazovyh sostavlyayushih v atmosfere, sozdannyi EKA i Roskosmosom po programme EkzoMars, poluchil novye, neozhidannye rezul'taty: metan v atmosfere Marsa ne obnaruzhen. V 2013 godu marsohod NASA K'yuriositi zaregistriroval nalichie metana, etot rezul'tat byl podtverzhden na sleduyushii den' orbital'nym apparatom EKA Mars-Ekspress. Problema yavlyaetsya takoi interesnoi, potomu chto na Zemle metan v osnovnom sozdaetsya organicheskoi zhizn'yu. Voznikaet intriguyushee predpolozhenie, chto kakaya-to forma zhizni – vozmozhno, mikroby – sozdaet metan pod poverhnost'yu Marsa. Odnako vozmozhny i drugie, ne svyazannye s zhizn'yu istochniki proishozhdeniya metana. Na kartinke pokazana nalozhennaya na izobrazhenie Marsa karta obiliya metana, poluchennaya v 2003 godu pri nablyudeniyah s Zemli. Otsutstvie metana, obnaruzhennoe orbital'nym apparatom EkzoMars, mozhet oznachat', chto na Marse imeyutsya neozhidannye processy, unichtozhayushie metan, ili chto metan poyavlyaetsya tol'ko v nekotoryh oblastyah na Marse, vozmozhno, tol'ko v nekotorye periody vremeni. Zagadka stanovitsya vse bolee interesnoi, i dlya ee resheniya chelovechestvu nuzhny eshe bolee tshatel'nye issledovaniya atmosfery nashei sosednei planety.
