Finding life in other places than earth requires many things. The United States has sent many probes to examine unfamiliar places in the solar system. Voyager, Mariner, Pioneer, and Magellan are just a few probes that have been propelled towards the universe for answers. As the U.S. sends probes looking for life, they are also gathering scientific information about the composition and geological patterns of the planet to see if life has a possibility to form. Trying to be discovered is also a hurdle that the U.S. is working to jump over. One example of this is the Pioneer 10 Probe. It was made for sending out into space for other life forms to find it. On this probe is a plaq

SETI has put forth many new ideas and proposals in the search. It is an institutionalized program that was proposed to NASA for the sole purpose of finding extraterrestrial life. The first search was that of Dr. Frank Drake and his OZMA project. (SETI) In 1993, congress had decided that SETI was a waste of time and stopped the funding for it, but that did not stop it from searching on. It went private with Dr. Drake and Dr. Jill Tarter leading the search. In 1997, Dr. Tarter and 32 other experts began meeting about how to “chart a path into the future.” She explains, “We have to grow this.” (Broad. 53) Still an SETI leader today, Dr. Tarter has plans for building an observatory in the moon where is it free of earthly interference and where it can scan the heaven for an unfamiliar “hello.” (Broad)

Numerous clues on the planet Mars have given scientists ideas of flourishing life. The Viking probes sent to Mars has found clues that at least primitive life may have existed earlier. This information was found by testing the atmosphere and soil of Mars. Its explanation for the idea of life was that it found a chemical composition in the rocks of Mars similar to that of Earth’s rocks. About twelve of these rocks believed to have come from Mars have been discovered on Earth. In 1996, NASA scientists and several universities announced that a four and a half pound rock found near the South Pole came from Mars. Its microscopic shapes resemble bacteria here on Earth. Scientists call these shapes microfossils – “the remains of microscopic organisms that lived on Mars several billions of years ago.” (Fradin. 23) Another probe sent to Mars for the search of life was the Mars Global Survey. It is a probe that will map the entire planet from its orbit. (Fradin. 24) NASA landed another probe called Pathfinder on July 4, 1997 to actually explore the surface of Mars. It analyzed the air and soil of Mars. Future plans of searching for life on Mars are sending back the Pathfinder probe in 2005 for the samples it retrieved. Also, in 2018, there is a plan for a human to finally explore Mars for his or her self. (Fradin. 25)

If we do find extraterrestrial life, then what will the future have in store for us? The importance of intelligent life is a key aspect. Humans and the capability to think is considered to be the most important thing in the universe, and if we have more intelligent life out there the better. Diversity will play a big role in extraterrestrial life. There are so many stars in the galaxy and a fair number of these stars have planets that are potentially hospitable for life to develop. The variety of life here on earth ranges so largely that it suggests a natural tendency for life to spread elsewhere throughout the universe. Another question to finding life other than what we know on earth what can we do? Information or advice from another highly intelligent and advanced civilization, or even gaining knowledge about its characteristics could be very beneficial and all humanity. A great increase in our efforts to achieve successful contact or interaction would be a very wise investment for us. After the other life form reaches earth, will it be able to survive here? Intelligent life has countless of billions of years to advance and change before there is any need to adjust to the end. Just as we evolve to our environment, the other creatures will evolve their new surroundings. By the time we reach a communication with other beings, intelligence will have progressed so much that they can figure out how to avoid the termination of all life, knowledge, intelligence, and wisdom.

People have devoted their lives to finding universal intelligence. Carl Sagan was a professor of Astronomy and Space Sciences and the director of the Laboratory for Planetary Studies at Cornell University. One if Sagan’s interest was the possibility and means of detection of extraterrestrial life. He has been closely a
