Title
Planetary Atmospheres Minor Species Sensor
Trace gasses are indicative of biologic activities and
geologic activities on planets and their satellites as well as asteroids and
comets. Detection of trace gasses on Earth can also advance our
understanding human impact on climate change. Trace gas detection in
Earth’s atmosphere as a balloon traverses the 30 km to the Stratosphere can be
daunting as temperatures swing below -60C and air density drops below a point
to sustain cooling of electronics by convection. This necessary first
step will qualify PAMSS, the Planetary Atmospheres Minor Species Sensor, and
the first mid-infrared intracavity laser absorption spectrometer, for space
flight. The prototype system has demonstrated sensitivity to molecular
absorption coefficients as small as 1 x 10^-5 cm^-1 (equivalent to a mixing
ratio as small as 30 ppbv at 1 atm), and this is by no means a fundamental
limit of PAMSS capabilities. We present the results of our work to fly
PAMSS to 30 km using Near Space Corporation’s Small Balloon System.
Technologies tested during the flight involve heat transfer and re-use, and autonomous
data collection using COTS, along with self-alignment techniques to ensure data
gathering throughout the flight with the goal of advancing the project to TRL6.
