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.
