This week's Question: NASA recently proposed a mission that one day may send astronauts, via a balloon, toward Venus' upper-atmosphere to research the possibility of a "cloud city community." Although the waterless planet has an unforgiving temperature of 1,000 degrees Fahrenheit, the clouds of Venus present an ideal spot for humans to roam from a spacecraft. The conditions at 31 miles above the surface are about the same pressure and atmosphere as Earth. The High Altitude Venus Operational Concept, or HAVOC, mission would start with a series of phased exploration sorties, followed by a robotic mission, a crewed ride, and the deployment of an uncrewed robotic airship in the atmosphere. NASA researchers say that if the phases of the mission are successful, permanent presence in Venus' atmosphere is possible. What do you think? Will we build a floating city above Venus?
