Integration of Compact Gamma-ray and Neutron counter (C-GRNC) Prototype into an Advanced Environmental Payload

We are developing a Neutron and Gamma-ray spectrometer for deploying it on the Moon and Mars, in orbit or on a lander, to find water and other volatiles of interest for in-situ resource utilization (ISRU).

Neutron and Gamma-ray spectroscopy is a powerful tool in geophysics, and planetary science as it is the only technique that provides bulk chemical composition and elemental abundance at depth, at a range of spatial scales, which – for planetary bodies – can provide lithology, mineralogy and chemistry. Importantly, such an instrument package can identify and quantify water and other key elements relevant to assessing planetary volatile abundances and evolution, assessing radioactivity and habitability to advance sustainable human exploration.

Objectives:

This project focuses on the integration of the Compact Gamma-ray and Neutron Counter (C-GRNC) prototype into an advanced environmental payload, enhancing its functionality for outdoor operations and remote data acquisition. The payload will be designed to withstand various environmental conditions while ensuring accurate data collection and transmission.

 

Key Tasks:

  • Payload Structural Design: Develop a robust and weather-resistant enclosure for the C-GRNC prototype and associated subsystems. Conduct structural analysis to ensure the payload's durability under outdoor conditions, including exposure to temperature variations, humidity, and physical stress.
  • Thermal Analysis: Implement thermal control mechanisms within the payload to maintain the C-GRNC and other components within their specified operating temperature ranges. This includes the integration of heating and cooling elements as needed.
  • Standalone Control System: Implement a Raspberry Pi-based control system to manage and operate the C-GRNC prototype independently. Ensure seamless communication and control between the Raspberry Pi and the C-GRNC.
  • Onboard Data Acquisition: Integrate data acquisition systems to capture measurements from the C-GRNC and other environmental sensors, including GPS, thermometer, barometer, and hygrometer.
  • Data Transmission: Develop a data transmission module to relay real-time or stored data from the payload to a remote monitoring station. Implement secure and efficient data transfer protocols.
  • Environmental Sensors: Integrate GPS for location tracking, thermometer for temperature monitoring, barometer for atmospheric pressure readings, and hygrometer for humidity measurements. Ensure accurate data collection and synchronization with C-GRNC measurements.
  • Wiring and Routing: Design a structured and efficient wiring and routing system within the payload enclosure to ensure the integrity of electrical connections and minimize interference between components.

By completing this project, we aim to create a comprehensive and autonomous environmental payload capable of precise radiation detection and environmental data acquisition in various outdoor settings. This integrated system will contribute to our understanding of environmental conditions and radiation levels while enabling remote monitoring and data analysis.
