Sensor for Determining Single Droplet Acidities in the Venusian Atmosphere

The cloud layers of Venus are known to have pressures and temperatures comparable those on Earth, but, at the same time, many details about environment inside them unknown. early consensus was that Venusian clouds composed droplets near concentrated sulfuric acid with very limited water availability; newer models, however, suggest a pH range between ?1 1, these imply some form neutralizing agent potentially complex chemical cycles. It is also possible different populations particles acidities. To answer questions, we propose an in situ acidity sensor can statistically determine acidities individual from (18 M) deionized water, based fluorescence pigment immobilized film read out using set excited LEDs camera. Here, present preliminary research prototyping results design for this sensor.
