Smart Core-Bit Probe (SCOPe) employs ruggedized MEMS-based sensors for real-time monitoring of sample core integrity (compositional or morphological changes) and drill health during sample acquisition. SCOPe enables comprehensive preliminary in situ measurements (both dynamic and static) during sample acquisition and before retrieving the sample. This results in maximum science return, and enables rapid and accurate analyses of mineralogy and chemistry of the sample from initial acquisition to the end of the sample acquisition and handling chain.
The current state-of-the-art of shallow coring technologies is hindered by a lack of integrated ruggedized sensors for real-time monitoring of the core drill bit in order to transform the core drill bit from a mere cutting tool to a probe. This enables monitoring of samples from initial acquisition to the end of the sampling chain to preserve the integrity of the sample, and maximizes science return for all targets, especially astrobiological and subsurface volatile (ice phase) targets.
SCOPe integrates ruggedized MEMS sensors into a core drill bit to expand its functionality from a mere cutting tool to a probe. SOCPe can be mounted to any core drill system that accepts 64-mm direct-system drill bit shanks. The focus of the probe can be changed, depending on the application, by changing the MEMS device inside the probe.
The specific aim of this innovation, and a key discriminator in this approach, is to develop a general and widely applicable framework “At-The-Bit-Technology” that expands the core drill bit functionality from a mere cutting tool to a probe, independent of the drilling mechanism to which the core drill bit is mounted. SCOPe would provide the first ever framework for implementing down-hole in situ microanalytical technology, real-time monitoring of sample core integrity (compositional or morphological changes), and drill health during sample acquisition.

Overview
The document discusses the Smart Core-Bit Probe (SCOPe), a cutting-edge technology developed by the Jet Propulsion Laboratory (JPL) at the California Institute of Technology, aimed at enhancing core sample acquisition in planetary exploration. SCOPe integrates ruggedized Micro-Electro-Mechanical Systems (MEMS) sensors into a core drill bit, transforming it from a simple cutting tool into a sophisticated probe capable of real-time monitoring of core sample integrity and drill health.
SCOPe's primary function is to provide comprehensive in-situ measurements during the acquisition of geological samples, allowing for the assessment of compositional and morphological changes. This capability is crucial for maximizing scientific returns, particularly for missions targeting astrobiological and subsurface volatile materials, such as ice. The technology addresses a significant gap in current shallow coring methods, which have been limited by the lack of integrated sensors for real-time monitoring.
The document highlights the importance of maintaining the integrity of samples, especially in the context of future missions like the Mars Sample Return Mission (MSR). It emphasizes that temperature control is vital, as samples must be kept below certain thresholds to prevent degradation. SCOPe's monitoring capabilities will enable scientists to track temperature and other critical parameters during sample acquisition and handling, thereby preserving the quality of the samples collected.
SCOPe is designed to be compatible with existing core drill systems that accept a 64mm direct system drill bit shank, making it a versatile addition to various drilling mechanisms. The technology aims to provide a general framework for "At-The-Bit-Technology," which enhances the functionality of core drill bits across different applications.
In summary, SCOPe represents a significant advancement in core drilling technology for planetary exploration. By integrating real-time monitoring capabilities into the core drill bit, SCOPe not only improves the efficiency of sample acquisition but also ensures the preservation of sample integrity, ultimately enhancing the scientific value of the materials collected during space missions. This innovative approach is expected to play a critical role in future explorations of planetary bodies, including asteroids, comets, and moons.
