A miniaturized aerosol spectrometer developed by scientists in NOAA’s Chemical Sciences Laboratory reached new heights on Monday, October 5 when it was delivered by a cargo capsule to the International Space Station orbiting greater than 250 miles above Earth’s floor.
The system, the Portable Optical Particle Spectrometer, or POPS, will assist monitor air high quality in the primary residing space of the area station.
Developed by NOAA physicist RuShan Gao, POPS makes use of an on-board laser to measure and rely aerosol particles between 140 nanometers to 2.5 micrometers in diameter. A micrometer is 1/1000th of a millimeter. A nanometer is 1,000 instances smaller than that. At six inches lengthy and 1.three kilos, POPS is about one tenth the scale and one fifth the price of comparable devices.
The instrument was built-in into Aerosol Dynamics Inc’s Ambient Particle Monitor, and ferried to the area station together with 4 tons of science experiments, crew provides and station on the Cygnus resupply capsule carried on an Antares rocket launched from NASA’s Wallops Flight Facility on Wallops Island, Virginia.
In a spacecraft cabin setting, the scale vary of indoor aerosols is far bigger they usually persist longer than on Earth as a result of they don’t seem to be eliminated by gravitational settling. High concentrations of inhalable particles on the area station could also be chargeable for crew complaints of respiratory and eye irritation and feedback about ‘dusty’ air reported to NASA. POPS will take part in a flight experiment which can present information on floating particulate matter within the air contained in the area station. Samples will likely be returned to Earth for chemical and microscopic analyses and can present the primary take a look at aerosol composition within the spacecraft.
POPS’ small measurement and light-weight weight have earned it one other high-flying mission in 2021. The instrument will likely be integrated as a science payload launched by the Arizona firm World View, for a sequence of high-altitude, long-duration flights aboard the corporate’s “Stratollite” balloons for a uniquely detailed take a look at the composition of Earth’s stratosphere.
The measurement vary of particles that POPS can detect is especially essential for understanding the local weather since they’re each sufficiently small to build up within the ambiance as a substitute of settling out, and enormous sufficient to effectively mirror daylight. The information will play a task in serving to NOAA to know baseline situations within the stratosphere.
