Ke ʻimi nei ka Opportunity rover i ka Red Planet mai ka makahiki 2004 a ʻaʻohe mea pono e hiki ʻole ai ke hoʻomau i kāna mau hana. Eia nō naʻe, i ka makahiki 2018, ua lele ka ʻino ma luna o ka honua, kahi i make ai ka mīkini mīkini. Ua uhi paʻa ʻia ka lepo i nā panela lā o Opportunity, i mea e nalowale ai ka mana. ʻO kekahi ala a i ʻole, i Pepeluali 2019, ua haʻi aku ka hui mokulele ʻAmelika NASA i ka make o ka rover. I kēia manawa ua ʻōlelo ka poʻe ʻepekema ua hiki ke hoʻoneʻe ʻia ka wai mai ka ʻili o Mars ma ke ʻano like. Ua loaʻa kēia hopena e nā mea noiʻi NASA i ʻike i ka ʻikepili i loaʻa mai ka Trace Gas Orbiter (TGO).
Manaʻo ka poʻe noiʻi i ka wā ma mua, he lewa ākea ʻo Mars a ma kahi o 20% o ka ili o ka honua i uhi ʻia i ka wai wai. Ma kahi o 4 biliona makahiki i hala aku nei, ua nalowale ka Honua Ula i kāna māla magnetic, a ma hope iho ua nāwaliwali kona pale ʻana mai nā makani pōʻino o ka lā, e alakaʻi ana i ka nalowale o ka hapa nui o kona lewa.
ʻO kēia mau kaʻina hana i hoʻonāwaliwali i ka wai ma ka ʻili honua. Hōʻike ka ʻikepili i loaʻa mai nā ʻike TGO ʻo nā ʻino lepo ka hewa no ka nalowale ʻana o ka wai mai ka Honua ʻulaʻula. I nā manawa maʻamau, aia nā ʻāpana wai i ka lewa i loko o 20 km o ka ili o ka honua, ʻoiai i ka wā o ka ʻino lepo i make ai iā Opportunity, ua ʻike ʻo TGO i nā molekele wai ma kahi kiʻekiʻe o 80 km. Ma kēia kiʻekiʻe, ua hoʻokaʻawale ʻia nā molekele wai i ka hydrogen a me ka oxygen, i hoʻopiha ʻia me nā ʻāpana lā. Aia ma nā papa kiʻekiʻe o ka lewa, ʻoi aku ka māmā o ka wai, hiki ke kōkua i kona lawe ʻia ʻana mai ka ʻili o Mars.
