The thickness and survivability of a cosmic ray-generated primordial comet refractory mantle, or `crust`, are presently predicted by laboratory data and corrected estimates of cosmic ray dose to be capable of surviving a new comet`s entry into the inner solar system over numerous revolutions.^It is suggested that, since this mantle may be as much as several meters deep, the probe apparatus of the projected CRAF and Rosetta spacecraft will have to be extended in order to reach the desired, unprocessed cometary material.^As things stand, there is a high probability that these missions will sample cometary matter than has been heavily irradiated and reprocessed in the Oort cloud.^28 refs.

A primordial comet is one that is believed to have formed along with the rest of our solar system appoximately 4.5 to 5 billion years ago, and is composed of the materials that were present before the Earth and other planets began to form.
They are believed to have formed in the outermost parts of our solar system, and are believed to be the "pieces" of debris that collected to form the planets as we know them today. Finding out what they are made of is important to astronomers because they are considered to be the building blocks of our solar system as we know it.

It's a comet that never came close to the sun.

Hi. One that has never passed close to any star including the Sum. It contains material in pristine condition, meaning nothing has changed the structure or elements in it.
