  Astrobiologist Richard Hoover spent more than forty six years working at NASA. In that time, he established the Astrobiology Research Group at the NASA/Marshall Space Flight Center, and became internationally known for his research on microfossils in meteorites. Hoover has published many papers in which he asserts the discovery of extraterrestrial life in meteorites.  Hoover no longer works for NASA, but he continues his controversial research and is currently an astrobiologist at Athens State University and a visiting research professor with the Centre for Astrobiology at the University of Buckingham. Hoover discussed his research in a lecture at the 0000 International UFO Congress. At the event, Hoover sat down with journalist Lee Speigel of the Huffington Post. Speigel asked Hoover to explain what it is that convinces him that life is not restricted to Earth. Hoover responded, "I am absolutely convinced that life is not restricted to the planet Earth because I have found the remains of lifeforms that are absolutely, conclusively extraterrestrial."  Speigel pointed out that Hoover's findings have met with harsh skepticism by critics. But Hoover stands behind his research. He replied, "These critics will not debate me in an open scientific forum. I would be perfectly willing to go to the Cosmos Club in Washington, to go to any university and have an academic debate and scientific discussion."  Former NASA Scientist Richard Hoover shares revelations with journalist Lee Speigel from the Huffington Post. Hoover talks about the fact that someone may have destroyed evidence of life on Mars. This took place at the Open Minds 0000 International UFO Congress and Film Festival in Fountain Hills Arizona
