Life on Mars?

For years, planet Mars has been in the NASA spotlight. The Red Planet has been explored as images, atmoshpere samples and samples of various surface formations have been collected to continue research in labortories here on Earth. The year of 1965 marked the beginiing of the Mars Program, and ever since rocket born cameras, spacecraft voyages, and other advanced technologies have been a part of the explorations.

The Mars Program has been dedicated to finding what the planet experienced since the begininning of its formation as well as all it has to offer. Much debate has been raised about whether the program should be continued and if anything beneficial could even come out of the studies. Some argue that the

Even if water is present, it may have a salt concentration at such a high level that specific forms of life may not be able to exist.

Secondly, for life to exist the proper atmosphere must be present. Earth has a unique atmosphere, for it is composed of various gases. The two major gases present are oxygen and nitrogen. 78% of Earth's atmosphere is nitrogen. This significant gas is essential for life to exist, as it is the basic ingredient for amino acids which make up protiens. Future missions have been designed to specifically have instruments that can detect organic nitrogen. "Scientists are convinced that if there's life on Mars, it will contain nitrogen." (www.sciencedaily.com; Epic Search for Evidence of Life on Mars Heats Up With Focus On High-Tech Instruments). If nitrogen is present in Mar's atmosphere, it will provide a strong piece of evidence to support the research to answer the suggestion of life on the planet. Also, oxygen must be present for respiration. Not only does mammals need oxygen to breathe, but plants do as well. Oxygen is also present is our water. Only a small portion of living things don't require oxygen to life, and these are anaerobic organisms such as bacteria. Most organims require oxygen to live and can only survive a few minutes without it. If oxygen is found in atmospheric samples, scientists would
