Ahhhh, I wish I could have heard her. She may have mentioned that cosmonaut story in the book. Funny if you think about it - hang yourself - but you can't because it is zero g. Her book "Spook" is sub titled "Science tackles the afterlife." Most of her research centered on spiritualists and mediums. Their heyday was in the early 20th century. Amazing what tho se people were willing to do to convince people they were in contact, and the chapter on ectoplasm was hysterical. The poor woman went to the Cambridge Library and checked out some preserved "ectoplasm" (cheeze cloth). She held up pulling it out to look at it silently begging the other serious researchers to leave for lunch. The cloth measured 10 feet by 3 feet. And the place the medium hid it was - well - unique. One thing that got me thinking after reading "Packing for Mars" was Neil Armstrong. He is now 82 years old! He left NASA in 1971 and got a teaching job at a small college in Cincinati. He has never writen his memoirs. While Buzz Aldrin did a stint on "Dancing with the Stars." Armstrong has been very private. He protects his privacy and his legacy (if he thinks of it that way) very strongly. Searching the internet, there was a story that Armstrong sued his barber of 20 years because the barber sold his hair clippings for profit. Made the barber donate the value to a charity. We are going to lose something important when he dies.
