Rate the following essay on its writing, argument, and language skills:
In the article "The Challenge of Exploring Venus" the author clearly describes the article. He supports everything he says, its backed up with more facts after another.

He explains how NASA is working on getting more knowledge about venus, but venus is too hot and extreme for a ship to land on it or even hover over it. the knowledge that they gained so far is being a distant away from the planet. The author says "Each previous mission was unmanned, and for good reason since no spacecraft survived the landing more than a few hours.

He talks about how venus is earths planetary neighbor. Venus is the cloest planet to earth in terms of density and size. Researchers cannot take samples of rocks, gas or anything else since no human can walk on venus. He says "many researches are working on innovations that would allow our machines to last long enough to contribute meaningfully to our knowledge of Venus." so possibly one day people will walk on Venus and we will discover more and more about our planets. We will soon gain the technology to reach Venus and other planets.
