Many of the answers that mankind and scientists are searching for lay deep underground in various layers that have formed over many millions of years. These inaccessible areas continue to hide the answers and proofs that many scientists and researchers seek.
In addition, in support of exploration of the planetary bodies in our solar system, it will be necessary to install a measurement unit, such as a lunar seismometer for measuring moonquakes, within the lunar surface. In order to isolate the seismometer from solar radiation and the extremes of heat and cold, it will be necessary to sink the seismometer into the regolith without leaving a hole above the unit for intrusion from the surface of the complicating ambient conditions.
In support of research on deep geologic formations, the way that scientists can sometimes try to access a small amount of this otherwise inaccessible material for analyses is to drill and bring up a core sample of the material. In some locations, core sampling is considered impractical or even destructive of the condition sought to be measured. Even if scientists can obtain a small core sample, their act of removing this material from its underground location will often change the material and contaminate the answers being sought.
It is a known uncertainty of physics and science that the act of retrieving and moving a material to observe it could change the properties of the material. By bringing a core sample out of the earth to a laboratory, the sample is subject to changes in ambient pressure, temperature, moisture content, and structure. The core sample is now in an altered state due to a changed relationship with other ground materials, the level of magnetism and other earth energies that pass through it, the exact directional position in the ground, the exposure to sunlight and artificial light, and a whole host of various electric magnetic pollution and signals and gases and toxins, etc.
