Core sample

A core sample was a cylindrical sample taken from a celestial body.

In 2151, Lieutenant Malcolm Reed and Ensign Travis Mayweather were the drilling team sent to the surface of Archer's Comet to extract a core sample of the comet, rich of eisillium. They had to place charges and create an explosion to get closer to the layer and were able to retrieve a core sample by using the drilling rig inside the crater.
