Can Mars be seen at night without telescope?

Mars’ Forbidding Climate
Mars is our best-known neighbor in space. Although Venus comes closer, Mars has gotten the lion’s share of study and publicity. The reason is that when Mars is closest to us, it is fully lighted by the sun and is easy to observe and study. I should warn you, though, when you look at Mars, it may disappoint you, for it is not as spectacular in a small telescope as the larger planets.
Mars is very different from the earth. It has an atmosphere less than one percent as dense as ours, and that is mostly carbon dioxide. There is little or no water on Mars, so the ice cap you see is not ordinary ice, but is solid carbon dioxide, what we call dry ice. It is now summer in Mars’ southern hemisphere, and the ice cap is shrinking. Under twenty-four hours of sunshine a day, it will be all gone in a few weeks.”
The highest temperature reported by space probes for Mars’ equator was about 60 degrees Fahrenheit, but overnight it plunges to 100 degrees below zero, even in midsummer. For more information on this subject, please go to jw.org "Online Library. Also for free downloads, or read online.
