Using modern technology, the group of 

explorers found created a drill that would 

protect them through the conditions of each 

layer as they traveled through the Earth to 

begin to colonize the core of the Earth. Before 

the group began their journey, they checked 

how the density and pressure would change 

as they traveled deeper and realized it would 

rapidly increase through each layer. Their goal 

was to make it to the center of the core and 

expand outwards to get the colony as large as 

possible.

The group filed into the drill they created, and 

checked the temperature. Air temperature, as 

they expected. They estimated the thickness 

of the crust to be 32 kilometers since they 

were nowhere near an ocean, and they began 

drilling down. It started slow, but the drill 

picked up speed and began a fast but steady 

pace downwards. As they got deeper, the 

mineral collector kept dinging as they collected 

more minerals and rocks, like basalt, granite, 

schist, and gneiss.

Once deeper, and closer to the Lithosphere, 

the group saw temperatures rising to nearly 

400 degrees C in some areas. The knew this 

was nothing compared to deeper layers, or 

even at the inner edge of the 100 km thick 

layer. The mineral collector beeped, but 

differently this time. In this layer only granite 

and basalt were found. The group turned the 

drill slightly so they could look for more 

minerals, but eventually they turned the drill to 

go deeper after finding nothing more.

As the group traveled into the Asthenosphere 

and got deeper, the temperature rose about 

100 degrees, but was nothing for the heat 

resistant shell of the drill. The estimation the 

group made for this layers thickness was only 

180 km, 80 km thicker than the previous layer. 

The mineral collector did not go off in this layer 

because the minerals were more of a plastic 

substance and did not get collected.
