The best way to learn about Venus could be with a fleet of balloons

Interest in the exploration of Venus has kicked up a notch lately, especially after a contested recent discovery of phosphine, a potential biosignature, in the planet's atmosphere. Plenty of missions to Venus have been proposed, and NASA and ESA have recently funded several. However, they are mainly orbiters, trying to peer into the planet's interior from above. But they are challenged by having to see through dozens of kilometers of an atmosphere made up of sulfuric acid.
