ISS Science for Everyone

Science Objectives for Everyone
Metals rust in the presence of oxygen and water, which are both present on the International Space Station. NanoRacks-Atidim High School-Rust Development in Space (NanoRacks-AHS-Rust Development) tests several common metals to study how rust develops in the microgravity environment. Results improve understanding of rust formation in space, which will help engineers designing future spacecraft and equipment for human spaceflight.

Experiment Description

Research Overview

  • NanoRacks-Atidim High School-Rust Development in Space (NanoRacks-AHS-Rust Development) is needed to better evaluate behavior of rust on chosen metals in order to determine specific materials to be used in space vehicles.
  • The goal of NanoRacks-AHS-Rust Development is to understand rust development on metals in the space environment.
  • NanoRacks-AHS-Rust Development tests new ways of creating space metallic components.

Description
NanoRacks-Atidim High School-Rust Development in Space (NanoRacks-AHS-Rust Development) begins immediately after arriving at the International Space Station (ISS). The first step is to open the fastener between the water and the metals in order to initiate the process of rust development. NanoRacks-AHS-Rust Development examines rust development on zinc, manganese, nickel, chromium, and iron. The water and metals are exposed to each other for as long as possible. Just before closing the investigation the second fastener is opened between the engineering lube WD40 oil and the rest of the tube to stop the process.

Applications

Space Applications
The investigation exposes samples of zinc, manganese, nickel, chromium, and iron to air and water, initiating the process of rust development. Understanding how these metals react can help engineers predict the life cycles of space components.

Earth Applications
Rust corrodes iron, iron alloys and other metals that are widely used on Earth, which can cause damage to infrastructure. Understanding how microgravity affects rust development sheds new light on the physical processes at work. In addition, the investigation was designed by high school students, who gain exposure and training to prepare them for careers in science, technology, engineering and mathematics.

Operations

Operational Requirements and Protocols
The MixStix are unclamped to combine different compartments, typically causing either activation or deactivation of the experiment. The MixStix are returned to the students.
A crew member removes the Velcro tabs to open the Module-9 Ext lid. The crew member unclamps the fasteners on the MixStix as directed, enabling the materials in the various chambers to flow. The crew member then shakes the MixStix (when directed) to mix the liquids thoroughly. Repeat for all MixStix. Crew member notes the time of MixStix activation and replaces the tubes back in Module-9. The lid is replaced and secured with the Velcro tabs.
