Nānā Hou o nā ao ʻulaʻula ma Mars  

Ua hopu ʻo Curiosity rover i nā kiʻi hou o nā ao pōuliuli ʻulaʻula i ka lewa o Mars. Kapa ʻia ʻo iridescence, ke kumu kēia ma muli o ka hoʻopuehu ʻana o ka mālamalama mai ka napoʻo ʻana o ka lā e nā aerosol hau maloʻo i loaʻa i ka lewa Martian. ʻO kēia ke kau ʻehā o ka nānā ʻana i ke ao pōuliuli a Curiosity i kahi kikoʻī a ʻike ʻia i kēlā me kēia manawa. ʻO ka nānā ʻana i ka iridescence i nā ao pōuliuli he manawa kūpono e aʻo ai i ka nui a me ka ulu ʻana o nā ʻāpana i ka lewa Martian. 

Ma ka 17 Ianuali 2025 (ka 4426^th ʻO ka lā Martian, a i ʻole sol, o ka huakaʻi a Curiosity), ua hopu ka Curiosity rover i nā kiʻi hou o ka noctilucent (ʻālohilohi i ka pō) a i ʻole nā ​​ao ahiahi i ka lewa Martian i ʻulaʻula ʻia me nā kala ʻulaʻula a me ka ʻōmaʻomaʻo. Kapa ʻia ʻo iridescence, ke kumu o kēia ʻano ma muli o ka hoʻopuehu ʻana o ka mālamalama mai ka napoʻo ʻana o ka lā e nā aerosol hau i loko o ka lewa Martian. I kekahi manawa, hana nā ao o ka pō i ke ānuenue o nā kala, e hoʻopuka ana i ka iridescence, a i ʻole ka "makuahine o ka momi".   

ʻO kēia ka ʻehā o ka ʻike ʻana i ke ao o Curiosity. Loaʻa ka hanana i kēlā me kēia manawa i ka wā o ka hāʻule mua ma ka ʻaoʻao hema. Ua kiʻi mua ka Curiosity rover i nā kiʻi o ka iridescence (nā ʻano kala ʻulaʻula e loli ana me ka neʻe ʻana) i nā ao Martian i 2019. Ua ʻike mua ʻia nā ao ahiahi ma Mars i ka makahiki 1997 e ka misionari Pathfinder.  

Aia ka Atmosphere o Mars i 95% CO₂, 3% N₂, 1.6% Ar a me ka meheu o O₂, CO, H₂O, CH₄, a nui ka lepo. Ma nā kiʻekiʻe kiʻekiʻe a me nā mahana haʻahaʻa, hana ʻia nā ao Martian i ka CO maloo₂ aiʻole ka hau maloʻo. Hoʻopuka kēia mau ao i ka iridescence. ʻO ka nānā ʻana i ka iridescence i nā ao pōuliuli he manawa kūpono e aʻo ai i ka nui a me ka ulu ʻana o nā ʻāpana i ka lewa Martian.  

ʻO nā rovers a pau i pae maikaʻi ma Mars, ʻo Curiosity wale nō (aia ma ka hema o ka equator Martian) i ʻike i nā ao ahiahi i hana ʻia i ka hau maloʻo. Malia paha, he hanana kiko'ī kēia.  

Ua manaʻo ʻia ʻo nā nalu ʻumekaumaha o ka lewa ma Mars ke kuleana no ka hoʻomaha ʻana i ka lewa e hiki ai i ka CO.₂ e hoʻokuʻu i loko o ka hau maloʻo e hoʻopuehu ana i ka lā e hoʻoulu ai i ka ʻike i loko o ke ao o ka pō.
