Rate the following essay on its writing, argument, and language skills:
Imagine studying a planet that is the closest to Earth in terms of desnsity and size. According to the article, Venus was probably covered largely with oceans and could possibly have supported various forms of life. NASA has thought about sending humans to study Venus. NASA has worked on other approaches to study Venus but the silicon carbide that was tested for Venus's conditions did not last long. Knowing more about Venus would be a great opportunity for Astronomers and everyone else.

Earth, Venus, and Mars are planetary neighbors, but they orbit the sun at different speeds. This means that sometimes we are closer to Mars or Venus. According to Paragraph 2, since Venus has been right around the corner at some times, there has numerous spacecrafts sent to land on this cloud-draped world. All the missions were unmanned when the spacecrafts were sent to study Venus. There has been many reason as to why Venus is a challenging planet for humans to study.

Even though NASA has thought of sending humans for a more up close and personal study. They would not be ready as to the spacecrafts cannot last very long in the conditions of Venus. NASA's solution to this was a blimp-like vehicle hovering 30 or so miles above the Venusian landscape.This would allow them to truly study Venus up close and personal and learn more about the planet. The vehicle would need to be approximately thirty-plus miles above the surface and causing this is the temperature at around 170 degrees Fahrenheit.

NASA having worked on different approaches to study Venus has been a real challenge. The silicon carbide that they tested on lasted for three weeks in the conditions of Venus. According to Paragraph 7, the device first envisioned was an old technology called mechanical computers in the 1800s. Modern computers expose to acid or heat capable of melting them could be an enormous disadvantage to NASA. This being the situation, NASA tends on using the old technology because it is more resistant to pressure, heat, and other forces which will be more of use.

In conclusion, Venus being a challenge to be thoroughly studied may be accomplished at some point with technology helping. Out of the other planets in our solar system, Venus was most likely to have supported life forms. Even though NASA's plan to send humans to study Venus is not yet possible, but it maybe in the later future. NASA had many ideas and ways to approach Venus. Now that they know the old technology called mechanical computers are more resistant, could highly help them out by a little or a lot.
