I read Hoyle and Wikiramasingh's books back in the late 70s and 80s. Fun reads and thought-provoking no matter what side you fall on the Panspermia argument. To those who downplay it as not really being RNA, this is one mission to a near-Earth asteroid. What are the odds you would even find a nucleobase? Amazing work and the contamination argument is always presented in light of any such discoveries. There was also the dismissal of fossil-like impressions in meteorites cut open as just looking like a known life form. I WANT TO BELIEVE ;)
