In the article "The Challenge of Exploring Venus," the author is suggesting that, despite its dangers, the planet Venus is worth putting time and resources towards learning more about the planet itself.

The auothor brings up many points on why it is so difficult to explore the planet. As the author stated in paragraph two, "no spacecraft survived the landing for more than a few hours". This can already be discouraging to some people, but others might think something is wrong with the technology we put there. In paragraph three we really start to see why the planet is so dangerous, "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 eperience on our own planet. [...] Venusian geology and weather present additional impediments like erupting volcanoes, powerful earthquakes, and frequent lightning strikes to probes seeking to land on its surface". At this point it sounds impossible to even be able to study Venus. Really, why would we want to study Venus? In paragraph four the author explains this, "Astronomers are fascinated by Venus because it may well once have been the most Earth-like planet in our solar system. [...] The planet has a surface of rocky sediment and includes familiar features such as valleys, mountains, and craters".

So we know that the surface of the planet has some of the harshest conditions and that the atmosphere is filled with acid, but the planet is similar to earth in structure. How would we be able to get to it and study it? In paragraph five the author begins to explain some ideas NASA has for being able to study Venus, "NASA's possible solution to the hostile conditions on the surface of Venus would allow scientists to float above the fray. Imagine a blimp-like vehicle hovering 30 or so miles above the roiling Venusian landscape. [...] 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". The important thing about this quote is that humans could survive in this blimp-like vehicle. However, if this were to happen scientists still would not be able to collect samples from Venus, they would just be able to observe it. The author also explains some electronics and machines NASA is looking into in paragraph seven, "some simplified electronics made of silicon carbide have been tested in a chamber simulating the chaos of Venus's surface and have lasted for three weeks in such conditions. [...] mechanical computers [...] these devices make calculations by using gears and levers and do not require electronics at all." These two ideas could be very useful for learning about Venus. The first one made of silicon carbide has already been able to survive for three weeks in similar conditions to Venus, and could be very important for landing on Venus. The author also brought up mechanical computers. The computers don't require electronics, as they said, and can much less fragile than modern computers. These could allow for some intersting ways to learn about Venus.

The author explained the dangers of Venus and why no mission has been very succesful. They also explained ideas for future missions that could possibly involves sending humans. I like the ideas they have, but I do not think the solutions are quite ready for humans to go to Venus. I am very excited to see where this goes and what new ideas scientists come up with.
