NASA's focus for human spaceflight seems to change every few years as we learn something new about what it will take to keep human beings alive out there. However, NASA usually picks one of a few targets. Will we go to Mars next, maybe back to the Moon, or perhaps an asteroid is a better option? NASA's Langley Research Center has put forward an interesting proposal — instead of the traditional choices, why not make the trip to Venus?

Sure, a human would be almost instantly annihilated on Venus' hellish surface, but not if they're floating among the clouds in a solar powered airship. This mission calls for a 129-meter airship, called the High Altitude Venus Operational Concept (HAVOC), which has a small habitat suspended below and solar panels for power.


Fish Uses Oyster Shells as Speakers

A clever fish has figured out that if it produces sounds in an oyster shell, the noises will carry over long distances, according to new research. The study, published in The Journal of Experimental Biology, is just the latest to show that fish are far from being silent. Many can produce sounds by vibrating their swimbladders and, like a fishy form of Morse Code, they can create different meanings based on the sounds.
