The ability to mine ice water in situ is of vital importance to enable future manned exploration of the solar system. In the past decade, orbital measurements have revealed that a third of the Martian surface contains shallow ground ice. Mars reconnaissance orbiter (MRO) shallow subsurface radar (SHARAD) data indicates the presence of debris-covered glaciers as well as buried ice sheets in the Arcadia Planitia (30°N–45°N) that are up to 170 m thick, consist of nearly pure ice, and are covered by at most 20 m of overburden. This data supports the implementation of two proven terrestrial technologies—coiled tube (CT) drilling and a Rodriguez well (RodWell)—for drilling and water extraction on Mars. Honeybee’s RedWater system combines these two technologies into one by first using a CT drilling approach to create a hole, and then, once the hole is made to depth, using the coiled tubing left in the hole as a conduit for water extraction. Models for system performance in this mode have been refined from a combination of U.S. Army Cold Regions Research and Engineering Laboratory (CRREL) research, data collected from Antarctic RodWells, and Honeybee testing. Honeybee plans to validate RedWater’s mechanism designs and extraction models through thermal-vacuum testing to TRL5 in 2020.

Redwater: A Rodwell System to Extract Water From Martian Ice Deposits

Due to challenges with COVID-19, this 17th Biennial has been moved to April 2021 and will now be offered in a virtual format. This conference aims to bring the experience and knowledge of experts in the aerospace industry together to share and discuss the latest research and engineering techniques that effect the exploration and settlement of space. Presentations will be made in multiple concurrent symposia over three days. Topics will include: Granular materials in space exploration, Exploration in utilization of extra-terrestrial bodies, advanced materials and designs for aerospace and terrestrial structures under extreme environment, Structures in challenging environments, and Space engineering, construction, and architecture for Moon, Mars, and beyond.
