Question
Throughout human history, the physical universe has often presented dangers to explorers. Nevertheless, were the risks worth the rewards? For example, when primitive humans left their tribal villages to search for food and water, they risked death or injury from dangerous animals. Later, when people sailed the oceans in search of new lands for settlement or trade, many died in terrible storms. The ocean of outer space has several unique challenges for explorers including being a vacuum, being strewn with meteors and having scarce sources of water.

TOPIC SENTENCE
Definition
One of the challenges that are unique to space is the fact that space is a vacuum, which is a risk for various reasons. First, in a vacuum there is no atmosphere and therefore no air pressure. Without air pressure, the human body has no oxygen to sustain itself. After too many minutes without oxygen, a person would lose consciousness and eventually die. Also, in a vacuum a person's blood will gradually begin to boil. Finally, without an atmosphere, the rays of the Sun can cause radiation poisoning.

6. Conclusion
There are other difficulties involved with space exploration, but these are three of the most important ones. In summary, without adequate air pressure, the unprotected human body may be seriously harmed in a vacuum. In addition, meteors can threaten human life and damage spacecraft. Finally, the lack of water in space means that human life may have a difficult time surviving on other planets. As one can see, the challenges of space travel are rather different from terrestrial dangers.
