ISS Science for Everyone

Science Objectives for Everyone
Water is essential for life, so safeguarding water supplies on space missions is critical for crew survival and health. The Water Monitoring Suite is a set of hardware that monitors microbes, silica and organic material in the water supply on the International Space Station. The hardware ensures crew members can test and monitor the safety of their water supplies on future space missions, especially on long-duration missions to Mars, asteroids or other destinations where Earth-based testing would be difficult or impossible.

Experiment Description

Research Overview

The Water Monitoring Suite contains three individual pieces of hardware to monitor different water quality properties.
  • RAZOR EX is a commerical off-the-shelf (COTS) unit with customized sample pouches developed for microbial monitoring of target microorganisms using polymerase chain reaction (PCR).
  • HACH Colorimeter is a COTS unit with a customized sampling kit. This kit demonstrates reactive silica monitoring.
  • Organic Water Module is a technology being developed at JPL. This kit demonstrates the technique for organic monitoring.

Description
The Water Monitoring Suite (WMS) contains three individual pieces of hardware to monitor different water quality properties. One of the three instruments, the RAZOR EX, launched on Space-X 9 (July 2016) and is currently being tested aboard the International Space Station (ISS). The RAZOR EX is a COTS PCR instrument with customized sample pouches for microbial monitoring. Monitoring of targeted microorganisms or total bacteria can be accomplished in less than one hour. The remaining two instruments, the HACH colorimeter and Organic Water Module are currently in flight development. The HACH Colorimeter is a COTS unit with a customized sampling kit to demonstrate reactive silica monitoring. The Organic Water Module is a technology being developed at JPL to demonstrate organic monitoring. Samplings are performed once a month for each instrument.

Applications

Space Applications
This investigation contains three pieces of hardware that measure microbes, reactive silica or organic matter. The microbial sampling equipment and colorimeter, which measures fine particles in the water, are both commercially available off-the-shelf (COTS), but contain custom-built sampling kits. The organic material sampling instrument has been developed at Johnson Space Center with the help of the Jet Propulsion Lab. All three instruments can measure varying aspects of water quality that are crucial for current and future space missions.

Earth Applications
Millions of people worldwide do not have access to clean water. Equipment that is fast and simple to use can improve water quality monitoring for remote areas, benefiting people on Earth.

Operations

Operational Requirements and Protocols

Operations require crew interface and crew taking samples and testing it through the suite of hardware. No real time commanding is expected; however, there is an ops team supporting WMS during its demonstration. There is software that the crew loads onto an ISS laptop for the Organic Water Module.

The Water Monitoring Suite team on the ground expects data to be downlinked once the data is available.
