“The official Search for Extraterrestrial Intelligence or SETI is 50 years old – And we are apparently still alone,” reports Scott Lafee for SignOnSanDiego.com.
“But that said, efforts to find evidence of life beyond Earth, intelligent or otherwise, have only broadened, deepened and become more determined over the years,” reports Lafee. “One of the things we’ve learned in the search for extraterrestrial life is that people get upset when you don’t find it,” said John Rummel, an astrobiologist at East Carolina University. “But you can’t just go out and find life. First you have to find places where life can exist.”
“Which, of course, is what people like Rummel, who once held the title of “planetary protection officer” at NASA, are doing,” reports Lafee. “There are planned and proposed missions to Mars to further explore its popular possibilities. There is much interest in certain moons in the solar system — Titan and Europa in particular — that are known to either possess water ice or perhaps hide a subsurface liquid ocean,” reports Lafee. “The presence of water is presumed to be a prerequisite for life to exist.”
