Evidence: The author supports this idea. That Venus is actually a planet. in our solar system, Venus is the second planet from our sun. While Venus is simple to see from the challenging place to examine more closely. Often referred to as Earth's twin," Venus is the closest planet to Earth in term of density and size, and occasionally the closest in distance too. Earth, Venus, and Mars, our other planetary neighbor, orbit the sun at different speeds. These differences in speed mean that sometimes we are closer to Mars and other times to Venus. Numerous factors contribute to Venus's perputation as a challenging planet for humans to study, despite its proximity to us.

A thick atmosphere of almost 97 percent carbon dioxide blankets Venus. Even more challenging are the clouds of highly corrosive sulfuric acid in Venus's atmosphere. On the planet's surface, temperatures average over 800 degrees Fahrenheit, and the atmospheric pressure is 90 times greater than what we experience on our own planet. These conditions are far more extreme than anything human encounter on Earth; such an eveironment would crush even a submarine accustomed to diving to the deepest parts of our oceans and would liquefy many metals.

If our sister planet is so inhospitable, why are scientists even discussing further visits to its surface? Astronomers are fascinated by Venus because it may well once have been the most Earth-like planet in our solar sytem. Long ago, Venus was probably covered largely with oceans and could have supported various forms of life, just like Earth. Today, Venus still has some feartures that are analogous to those on Earth The planet has a surface of rocky sediment and includes familiar features sych as valleys mountains, and creaters. Furthermore, recall that Venus can sometimes be our nearest option for a planetary visit,a crucial consideration given the long time farmes of space travel. The value of returning to Venus seems indisputable, but what are the optionsfor making such a mission both safe and scientifically productive?

The National Aeronautics and Space Administration (NASA) has one particulry compelling ideafor sending humans to study Venus. NASA's possible solution to the hostile conditions on the the surface of Venus would allow scientists to float above the fary. 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, temperature would still be toasty at around 170 degrees Fahrenheit, but the air pressure would be close to that of sea level on Earth.

Striving to meet the Challenge presented by Venushas value, not only because of the insight to be gained on the planet itself, but also because human curiosity will likely lead us into many equally intimidating endeavors. our tarvels on earth and beyond should not be limited by dangers and doubts but should be expanded to meet the very edges of imagination and innovation.
