Lunar polar volatiles mission: Canadian science definition team opportunity

1. Overview

This solicitation is anticipated to result in the selection of four scientists to be coordinated by a Canadian Space Agency (CSA) Mission Scientist, who will comprise the Canadian Science Definition Team (SDT) for a low cost Lunar Polar Volatile Mission. This solicitation will result in no funding awards, however travel to meetings will be supported as needed.

Should a lunar polar volatiles mission be approved in the future, the CSA anticipates a competitive request for proposals for Participating Scientist awards. Membership of the SDT will not preclude eligibility to respond to such a Participating Scientists request for proposals.

1.1 Introduction

Under the Exploration Core program, the CSA has developed terrestrial prototypes of rovers, a drill, avionics, advanced vision systems and other payloads. National Aeronautics and Space Administration (NASA) has expressed interest in having the CSA contribute the Drill and Rover to a potential low-cost lunar mission carrying the RESOLVE (Regolith & Environment Science, and Oxygen & Lunar Volatile Extraction) payload, which would be expected to land in an area of limited solar illumination where volatiles may be trapped in the sub-surface. RESOLVE objectives, investigations and instruments are described in detail in reference documents (RD-1:3)

The purpose of this SDT is to define the Canadian scientific contributions to a potential RESOLVE mission. The SDT will interact with Contractors selected under a Request for Proposals for an Exploration Core Concept Study for a Lunar ISRU platform. It is anticipated that there will be two Contractors undertaking parallel concept studies. SDT members will have access to Contractor proposals and deliverables under the terms of non-disclosure agreements.

Specifically, the SDT will support the development of contractor concepts for imaging systems on the rover, derive requirements for regolith properties experiments with the rover and drill itself, and taking into consideration public participation activities. The SDT will, in addition, investigate collaborations with the US using the existing RESOLVE payload.

1.2 RESOLVE overview

Scientists and engineers have been investigating the presence of resources in the lunar regolith for many years. Since 1994, a number of missions to the Moon have indentified the presence of hydrogen in the lunar regolith at the poles. In light of these findings, the next logical step and primary goal of the lunar ISRU mission is to verify the presence of water and other volatiles on the Moon by direct, ground truth measurements of the regolith in and around permanently shadowed regions.

The integrated RESOLVE payload consists of the following instruments: Neutron Spectrometer, Near InfraRed Spectrometer, Drill Subsystem, Oven Subsystem, and, Lunar Advanced Volatile Analysis (LAVA) subsystem.

The RESOLVE mission objectives are to use this payload to:

  • Verify the existence of and characterize the constituents and distribution of water and other volatiles in lunar polar surface materials
    • Map the surface distribution of hydrogen rich materials (Neutron Spectrometer, Near-IR Spectrometer)
    • Extract core sample from selected sites (Drill Subsystem)
      • to a depth of 1m with minimal loss of volatiles
    • Heat multiple samples from each core to drive off volatiles for analysis (OVEN Subsystem)
    • Determine the constituents and quantities of the volatiles extracted (LAVA Subsystem)
      • Hope to find and quantify H2, He, CO, CO2, CH4, H2O, N2, NH3, H2S, SO2
      • Survive limited exposure to HF, HCl, and Hg
  • Demonstrate the ISRU Hydrogen Reduction Process to extract oxygen from lunar regolith
    • Heat sample to reaction temperature (OVEN Subsystem)
    • Flow H2 through regolith to extract oxygen in the form of water (OVEN Subsystem)
    • Capture, quantify, and display the water generated (LAVA Subsystem)

A RESOLVE design reference mission is being developed for a total lunar surface duration of 6-12 (Earth) days with periods in sun and in shadow. This design reference mission will be refined.

Landing site selection criteria include

  1. the presence of sub-surface volatiles
  2. direct to earth communications
  3. traversable terrain
  4. daylight illumination.

Cabeus Crater is being considered as one possible location.
