Rate the following essay on its writing, argument, and language skills:
Space travel is not new to humanity nor is it something that has not already been accomplished. With the breach of Mars's soil having already occured scientist and space explorers have set their sights on the next challenge, Venus. Venus is sometimes closer to Earth than Mars and at other times Mars is the one closer to Earth, but of the two Venus is the closest match to Earth "in terms of density and size" and thus has been named Earth's "twin" making it a place of great interest for scientist, and those interested in space exploration because no other planet comes as close to matching Earth's conditions. Studying Venus could give hints about the future of Earth.

In "The Challenge of Exploring Venus" the author gives strong support to the idea that the pursuit of studying Venus is a worthy cause despite the dangers presented by the task. Knowledge of Venus would be extremely beneficial because Venus is one of the most interesting planets in Earth's solar system because of it's similarity to Earth. With the large number of similarities that Venus currently shares with Earth it wouldn't be terribly surprising or strange if Venus was once a planet "covered largely with oceans and" that "could support various forms of life". There is no way to tell if any of this is true, however without being able to travel to Venus and explore the planet. Only by exploring the planet and studying pieces of the planet such as small bits of land can noteworthy discoveries about Venus be made. Confirming or disproving the Earth-like Venus idea is not the only reason why studying Venus is a worthy pursuit. Another reason is that "human curiosity will likely lead us into many equally intimidating endeavors" and the curiousity of humans and their travels on Earth "should not be limited by dangers and doubts" according to paragraph 8. This statements shows that gaining the ability to study the planet Venus is about more than just the planet and also expands to include the breaking of the limitations that stop exploration due to "dangers". By expanding to meet the challenge that Venus presents humans as whole will prove that they have the ability to explore and learn about nearly everything removing some of the limits of human exploration.

In conclusion the author's support of the idea that studying Venus is a worthy pursuit despite the dangers is extremely strong because the author gives noteworthy reasons as to how the pursuit would be beneficial to exploration and humans in general. The author states that the pursuit of studying Venus will open doors into the pursuit of studying other dangerous places, or areas of interest such as animals, and others. The author also sites the idea that more knowledge of the Earth's "twin" could in fact help give insight on Earth as well by giving humans an idea of what Earth could become in the future and perhaps by studying Venus scientist could find a way to prevent Earth from becoming Venus-like. The author's reasonings are strong and prove to be thought invoking and the author avoids the idea of risks that are not needed.
