For more than half a century, scientists have wondered about the possibility of life in Venus’ clouds. Unknown chemistry leaves the possibility that certain regions of Venus’ atmosphere are habitable.
In situ atmospheric measurements using a suite of modern instruments will allow us to determine whether cloud decks possess the properties necessary to sustain life as we know it. Important habitability factors are the droplet acidity of cloud particles and the water content of the cloud layer. Determine the acidity and water content (and their variability) of droplets, as well as confirm the presence of metals and other non-volatile elements necessary for the metabolism of life, confirm the presence of organic matter, and search It envisions a suite of equipment for Biosignature gases as signs of life.
Instrument for both astrobiology-focused missions, scientific targets, and large atmospheric probes with parachutes lasting about 1 hour in the cloud layer (40-60 km) or fixed-altitude balloons operating at about 52 present. km above ground. The latter relies on four deployable mini-probes to measure habitable conditions in low cloud regions.
This mission will determine whether a subset of cloud particles are non-liquid and characterize cloud particle heterogeneity, thereby informing sample collection and storage methods for return journeys to Earth. I am preparing to return.
