re: The news item
These are the clues I see and will be watching for that show concern over the 2 rocks you and I have mentioned. Nasa and Gov won't come out and say it to the public, but this manned mission alone shows something is up besides just science. We want to learn about the material makeup of an asteroid so we know how to deal with it in 2029-2036 or 2041.
Stay Tuned as the years go by leading up to said dates.
