I noticed some errors the Viking Program article. (I worked on that program and was responsible for sterilization of the two landers.) So I jumped in and cleaned up a couple of paragraphs.
I have benefitted from using many Wikipedia articles, but up to now have felt that their authors knew a lot more than I did. So I'm not likely to have an opportunity to make more edits.
My primary interests are particle physics, cosmology, math, chemistry and history.
