Evidence: The second issue is safety. According to NASA, they have a solution for getting a spaceship to Venus carefully and safely. "Imagine a blimp-like vehicle hovering 30 or so miles above the roiling Venusian landscape. Just as our jet airplanes travel at a higher altitude to fly over many storms, a vehicle hovering over Venus would avoid the unfriendly ground conditions by staying up and out of their way. At thirty-plus miles above the surface, temperatures would still be toasty at around 170 degrees Fahrenheit, but the air pressure would be close to that of sea level on Earth. Solar power would be plentiful, and radiation would not exceed Earth levels. Not easy conditions, but survivable for humans." (paragraph 5). NASA has a soultion for the safety issue that was recently brought to their attention. The people who want to go and explore Venus now believe that this is one of the final steps toward actually getting off of the ground. If NASA trains astronauts well enough, tries to simulate the conditions on Venus, and everything works well; there is noting holding them back.
