Emissary 2 -The Sixth Extinction - Scott K Bywater - Bog

Mitch and Jessy Taylor are on the Moon, fully suited, collecting mineral specimens, when they find oxidised minerals from an ore deposit in Mendeleev Crater on the Lunar Farside and incredibly, they are spectacularly crystallised. It totally shatters Earthly thinking; plentiful oxygen, water and pressure on the grey, dead Moon! Then there is the bizarre object they find sitting within the oxidised zone. God knows how long that had been there. As to how it got there, well, that was a whole other question. Someone or something had clearly placed it there. As they space hop and time travel through the Cosmos, they are made aware there are only a few truly Earth-like planets in the Universe and they must be looked after no matter what. Enter the Bantha that have taken it upon themselves to be the guardians of those worlds and ensure that they are preserved at all costs. Humanity attempts to achieve the 'no carbon atmosphere' deadline imposed by the Bantha to eliminate carbon energy and implement fusion energy for preservation of planet Earth; but can they?
