OBJECTIVES

Continue the DAFT particle-counting campaign on ISS to build a more representative particulate baseline for spacecraft smoke-detector design.

Sensors & measurements
  • P-Trak ultrafine particle counter
  • Isopropyl-alcohol condensation chamber
  • Light-beam particle detector
Variables tested
  • Repeatability of microgravity particle counts
  • Ambient particulate variability across ISS locations
  • Detector discrimination between dust and smoke-sized aerosol
Key findings
  1. 01Extended the DAFT aerosol measurements with additional ISS test points.
  2. 02Reinforced the finding that on-orbit particulate sizes can exceed typical ground values.
  3. 03Provided background data needed for detectors that must distinguish dust from smoke.
