7.9A Concepts
There are many requirements for life, as currently understood, to exist and persist. Characteristics of objects in our solar system such as proximity to the Sun, presence of water, atmospheric composition and a magnetic field contribute to the ability to support life. Data about the characteristics of objects in our solar system have been gathered using telescopes, satellites and unmanned probes.
Proximity to the Sun contributes to temperature ranges experienced by a celestial body. Distances that are too close or too far from that Sun create extreme temperature conditions that are considered inhospitable to life.
The presence and composition of an atmosphere contributes to the ability of life to exist. Atmospheric gases help regulate extreme temperature variations and ozone in the atmosphere shields living things from harmful ultraviolet radiation. The magnetosphere, formed by Earth’s magnetic field, protects life from the charged particles of the solar wind.
Earth is known as the water planet with about 70% of its surface covered by water. All life on Earth depends upon the presence of water. There is geological evidence that liquid water was once present on the surface of Mars. Scientists speculate that water exists, in various states of matter, on other celestial bodies in our solar system

10. Background info for questions
Extreme temperature variations, the vacuum of space, and a microgravity environment are all factors that require design accommodations that enable manned space exploration. Specialized life support systems are required by astronauts in space vehicles, within the space station, and in space suits.
Space suit technology provides a life support system for the astronaut by regulating temperature and pressure, as well as providing oxygen and protection from the space environment.
Astronauts must exercise regularly while in space because a microgravity environment can cause muscles and bones to become weak and less dense. Handles, tethers and Velcro® straps are accommodations that help astronauts to move around, sleep safely and complete other tasks that normally utilize the force of gravity.
Astronauts must use complex radios and computers in order to communicate with one another and with a mission team on Earth. These instruments also help them conduct research and repair damaged equipment and satellites.
