RedWater: Extraction of Water from Mars’ Ice Deposits
Honeybee Robotics has designed, built, and tested a TRL4/5 system known as RedWater, intended to drill into the surface of Mars and melt/extract water from locations identified by the Shallow Subsurface Radar, SHARAD. RedWater combines proven terrestrial technologies to extract water from the subsurface Martian ice. Rodriguez Wells, or RodWells, are a type of water well employed in Antarctica to maintain large pools of liquid water within an ice sheet and pumping water to the surface while heating and recirculating a portion to facilitate continuous well growth. RedWater also repurposes coiled tube drilling technology, which uses a thin-walled metal or composite tube to drive a bottom hole assembly into a borehole; the coiled tube itself is wound onto a drum and deployed by an injector system which transmits the required drilling forces through the tube as it is driven down. The combination of these two technologies with Honeybee’s existing rotary percussive drilling and pneumatic transport technologies make for an efficient means of producing large quantities of liquid water on Mars. Honeybee is currently working on evolving this technology to TRL6 and will be conducting end-to-end TVAC testing in 2022
RedWater: Water Mining System for Mars
Water ice in the form of debris covered glaciers or ice sheets that could be up to hundreds of meters thick has been discovered and mapped in the mid latitude of Mars. This presents a unique opportunity for in situ resource utilization (ISRU) of water, where the location could be favorable for a future human base. Under NASA funding, Honeybee Robotics developed and demonstrated water extraction from subsurface ice with a Technology Readiness Level (TRL) 5 RedWater system in a Mars-simulated environment that utilizes 2 proven terrestrial technologies: coiled tubing (CT) and the Rodriguez well (a.k.a. RodWell). CT is a continuous length of tube (metal or composite) that is unspooled from the surface and can be used to advance a bottom hole assembly through the overburden layer and into the underlying ice. The RodWell is a method of melting a well in subsurface ice and pumping the liquid water to the surface, which has been demonstrated and used to support polar operations in both Greenland and Antarctica. The aim of this article is to report the results of end-to-end testing of the TRL-5 RedWater system in −60°C ice and at Mars ambient pressure (and compare the results obtained in an Earth ambient environment). The performance of the system was evaluated in terms of drilling with pneumatic cuttings clearing, melting a well, and extracting the water from the well to a tank at the surface. After performance evaluation, the validated figures of merit may serve as input to higher level efforts, such as the design and development of integrated, water-rich habitat system architectures that rely on ISRU-derived water
