Richard C. Hoagland is a researcher and investigator in the area of space exploration. He is best-known for his claims that NASA routinely covers up information they do not want known, and/or that NASA is too incompetent to provide accurate information.
According to his website, Hoagland has been employed as a space museum curator, a NASA Consultant, and science advisor to CBS News.
According to his critics, Hoagland's work is unscientific, selective and evasive. Many have pointed to the fact that Hoagland still refuses to admit that the "Face on Mars" is a natural feature, and see this as an example of his intransigence.
