People on Earth have long looked at Mars with excitement
10 and fear. Mars is Earth’s nearest neighbor and has an
20 environment similar to Earth’s in many ways. The surface
29 of Mars is much like the surface of parts of Earth, dry and
42 hard. Temperatures on Mars range from –225° to 60°
49 Fahrenheit (-140° to 25° Celsius). There are important
55 differences, too. The atmosphere of Mars is almost all carbon
65 dioxide and doesn’t have enough oxygen to support humans.
74 On Mars, gravity, the force that pulls us toward the ground,
85 is not as strong as gravity on Earth.
93 However, of all the planets in the solar system, Mars
103 is the one that seems most possible for humans to visit and
115 even colonize. It is close to us, and it has a surface and
128 surface temperature most similar to that of Earth. 136
