Aerobot designed for hell-world Venus first braves something worse: Nevada
Remember life on Venus? One of the telescopes had 'an undesirable side effect' that could kill off the whole idea
The balloon is described as"balloon within a balloon," nestled inside is a rigid helium balloon that can contract and expand to increase and decrease pressure. To fly higher, the helium gas from the inner balloon is blown into the outer balloon, which expands to make the whole device more buoyant. To fly lower, the outer balloon pumps helium back into the inner one making it shrink and fall.
The team is working on scaling up the prototype. The final design will be three times bigger, measuring 12 meters in diameter and probably won't weigh more than a thousand kilograms. The ultimate goal is to send a fully-fledged aeroblot that could descend into Venus' clouds to hitch a ride on the planets' winds, where it could float around travelling east to west, for at least 100 days. It would carry a range of instruments capable of detecting earthquakes, analyzing the chemical composition of its atmosphere, and viewing the planet's surface.
