I saw an article that said that the atmospheric density at the surface is
2 times that of Earth, the gravity is 1/3 that of Earth, and that a
human could devise wings and be able to fly like a bird.


The project team's most recent paper says atmospheric density is 4x
Earth at Sea Level, viscosity is 3x smaller than Earth (be careful of
propeller speed) and gravity is 1/7 of Earth's.

"Daytime" surface illumination is 1000x less than Earth or 1000x full
moonlight predominately in red and near IR light, thus a human explorer
would get a largely dim B&W experience w/o a headlight.
