text: In addition to Venus' extreme conditions, the challenge of collecting physical evidence from the planet would be extremely difficult as well. Even though humans could possibly hover 30 miles above the ground level, the texts states that the vast distance would provide only "limited insight on ground conditions," and it would "[render] standard forms of photography and videography ineffective." Along with that, the author admits that "researchers would not be able to take samples...from a distance." The challenge that the study provides would simply not be worth the time, money, and risks. If man were to go to extreme lengths to reach within 30 miles of a planet and not be able to collect and evidence or data, it would not be a successful mission if the goal was to obtain new information about the planet.
