The Last Frontier: Mars
For more about Mars, check out
this page.
This week's topic is Mars. Mars
is the fourth planet from the Sun, of course, but first, let's take a step
back in history to see how Mars was named.
Mars, or Ares, is the god of War. Mars is known as the red
planet. Since war brings red blood, it probably was how this planet was
named.
Many spacecraft have gone to Mars. The first
was Mariner 4 in the year 1965. Several others followed, including Mars
2, the first spacecraft to
land on Mars, and the two Viking landers in 1976. Finally, the Mars
Pathfinder reached Mars on July 4, 1997, the United States' independence day.
Mars is believed to have once had water. There are many canyons
and erosion spaces that look like they could once could have been
oceans or rivers. This indicates that at some time in the past there probably was
water on the surface. Still, this was a very brief thing, and only
existed about 4 billion years ago.
Now, Mars has a very thin atmosphere. It's made mostly of carbon
dioxide, nitrogen, argon, traces of oxygen, and, of course, water.
