OBJECTIVES

Verify that a modified P-Trak ultrafine particle counter, a key SAME component, works in microgravity and can characterize ISS airborne particulate before SAME flew.

Sensors & measurements
  • P-Trak ultrafine particle counter
  • Isopropyl-alcohol condensation chamber
  • Light-beam particle detector
Variables tested
  • Ultrafine particle counts in microgravity
  • Particle counter operation without gravity-driven alcohol return
  • Ambient ISS particulate levels
Key findings
  1. 01Demonstrated a hand-held commercial particle counter in the ISS atmosphere.
  2. 02Data indicated low particulate levels relative to the Shuttle, consistent with the smaller ISS crew and its filtration system.
  3. 03Average particle sizes on orbit were larger than on Earth, possibly due to spacecraft filtration efficiency.
  4. 04Established the median particulate baseline needed to distinguish ordinary dust from dangerous smoke.
