Rate the following essay on its writing, argument, and language skills:
Exploring planet Venus is difficult and dangerous. In the text it says that "Venus has the hottest surface temperature of any planet in our solar system". Astronomers have shown that Venos may have been the most earth-like planet in our solar system. Solar power would would be plentiful, and radiation would not exceed levels. It wouldn't be easy but it would be survivable for humans. NASA wants to hover above Venos so it wouldn't be that dangerous going on the ground but that means they will be 30 miles above it. They can't reall get samples of rocks, gas, or anything because of how far away they are from planet Venus. NASA is alwso thinking about sending mechanical computers to the planet so they could see from the computers point of view. A mechanical computer was first made in the 1800's and they are very powerful and quick but could be really delicate to physical conditions.
