Description

Coring tools have been used etlectivelv on the Moon, but to date no such tools have been used on any other extraterrestrial surface. The lunar experience includes both manual (Apollo) and robotic (Luna) systems . These coring systems were concerned primarily with acquiring samples from depth for return to Earth or for the creation of instrument emplacement holes (e .g ., heat probes). Current designs for planetary drills differ from the lunar tools primarily in that they are integrated with robotic instrumentation for remote analysis, but the role of the drilling or coring system remains one of acquiring samples that ... continued below

Description

Coring tools have been used etlectivelv on the Moon, but to date no such tools have been used on any other extraterrestrial surface. The lunar experience includes both manual (Apollo) and robotic (Luna) systems . These coring systems were concerned primarily with acquiring samples from depth for return to Earth or for the creation of instrument emplacement holes (e .g ., heat probes). Current designs for planetary drills differ from the lunar tools primarily in that they are integrated with robotic instrumentation for remote analysis, but the role of the drilling or coring system remains one of acquiring samples that must be extracted from the core barrel for analysis . Missing from current sample collection systems is a tool that can double as both a conng device and a sample holder. This dual utility can minimize the number of motions, the mass, and the power required for several classes of instruments in planetary surface exploration. To be effective, such a system must be durable and simple in operation. Hollow CVD diamond drills possess the hardness, excellent cutting properties, and heat resistance required for drilling into a wide variety of rocks and minerals. Because CVD diamond is also unreactive and transparent to infrared radiation and to X-rays of moderate to high energry, it can be used as a sample holder in various instruments for X-ray diffraction (XRD), Xray fluorescence (XRF), infrared spectroscopy, Raman spectroscopy, and thermal analysis.
