Rate the following essay on its writing, argument, and language skills:
the author suggests that studying venus is worthy pursuit despite the danger it presents because this planet is the most difficult for exploring. It has 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. Other reason is the temperatures this are over 800 degrees Fahrenheit, and the atmospheric pressure is 90 times greater than what we expierence on our own planet.

But the astronomers are fascinated by venus because it may well once have been the most Earth-like planet in our system this idea have a good support because 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 features that are analogous to those on Earth.

NASA is working on other approaches to studying Venus. For example, 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. Another project is looking back to an old technology called mechanical computers.

Striving to meet the challenge presented by venus has value, not only because of the insigh to be gained on the planet itself, but also because human curiosity will likely lead us into many equally intimidating endeavors.

Humans have sent numerous spacecraft to land on this cloud-draped world. Each previous mission was unmanned, and for good reason, since no spacecraft survived the landing for more than a few hours. maybe this issue explains why not a single spaceship has touched down on Venus in more than three decades.
