He tātaritanga o nga tauira toka kei roto i nga taputapu Tauira i Mars (SAM), he taiwhanga iti kei runga i te Curiosity rover kua kitea te noho mai o nga puhui waro nui rawa atu i Mars ki tenei ra. I kitea e te roopu rangahau te noho mai o nga mekameka alkanes decane (C10H22), koretake (C11H24), me te dodecane (C12H26) he toenga o nga waikawa ngako waikawa undecanoic, waikawa dodecanoic, me te waikawa tridecanoic, i tiakina i roto i te tauira. Ko te puna o nga ngota ngota kaore e taea te whakapumau i te mea i ahu mai nga waikawa ngako i nga puna abiotic, i nga puna koiora ranei.
I te tau 2015 i kitea tuatahitia nga ngota rauropi o Martian i roto i tetahi tauira i tapaina ko "Cumberland". Ko te kitenga o naianei mo nga mekameka waiwaro waro roa, te undecane, me te dodecane kua mahia ma te whakamahi i te tauira ano. Ko te tauira pea he waikawa ngako mekameka roa e hono ana ki nga tukanga koiora. Engari ko te rover Ko te whare taiwhanga paku kaore i te arotau kia kitea nga waikawa ngako mekameka roa.
Ko te tauira "Cumberland," i werohia e te Curiosity rover i te tau 2013 mai i te waahi o Mars' Gale Crater e kiia nei ko “Yellowknife Bay” te waahi o te roto tawhito. He maha nga wa i akohia ai te tauira me te Sample Analysis at Mars (SAM) mini-lab ma te whakamahi i nga tikanga rereke. Kua kitea he nui te kohuke uku, te whanariki, te waikawa me te mewaro.
Ko te kitenga o nga toenga waiwaro mekameka roa nui ake o nga waikawa ngako e tohu ana kua piki ake te matū prebiotic i Mars. Heoi, ko te whakapumautanga o te ora ki Mars me whakahoki mai nga tauira o Mars ki te whenua mo te hohonutanga o te tātari. Ko te kitenga o naianei ka kaha ake te kite i nga waitohu koiora o te oranga ki Mars ma te whakamahi i nga taputapu maamaa ka whakahokia mai nga tauira ki te whenua a muri ake nei.

 instrument, a mini laboratory onboard the Curiosity rover has revealed presence of the largest organic compounds on Mars to date. The research team detected presence of long chain alkanes decane (C10H22), undecane (C11H24), and dodecane (C12H26) which were remnants of the fatty acids undecanoic acid, dodecanoic acid, and tridecanoic acid, respectively preserved in the sample. The source of the molecules cannot be confirmed as the fatty acids may have originated from either abiotic or biological sources.){kind=link}
