ISS Science for Everyone

Science Objectives for Everyone
Foam Casting and Utilization in Space (FOCUS) is an industrial materials experiment to investigate foam formation and stability in microgravity.
Science Results for Everyone
This experiment investigated foam formation and stability in microgravity. Researchers produced foams in microgravity using multi-capillary foam generators that were pre-infiltrated with aqueous suspension and had controlled gas flow. Comparing the foams with ground-based references revealed minimal structure differences at low gas flow rate and largest average bubble sizes at higher flow rates. Foam stability was not improved by eliminating gravity, indicating that foam decay in this suspension is not connected with gravity induced drainage. Foam volume did increase in microgravity, indicating that with the foam generators used, less gravity equals more foam. This is consistent with previous results.

Experiment Description

Research Overview

  • Foam Casting and Utilization in Space (FOCUS) will demostrate a new technology to produce nanoparticle stabilized foams on the International Space Station.

  • FOCUS will be performed in the Biological Laboratory (BioLab) of Columbus, to utilize the video camera. This investigation requires minimal crew time beyond activation and deactivation.

To demonstrate a new technology to produce nanoparticle stabilized foams under microgravity conditions. To collect scientific data on the evolution and stability of such foams under microgravity conditions. To develop a computation tools for ground-based applications.
