Description Space Adventures would be glad to send Alice Kramden to the moon ... but Ralph's bus driver salary could be a problem. The private spaceflight company has announced that Alice (or more likely Oprah) may purchase one of the two available seats on DSE-Alpha (for Deep Space Explorations) -- its first mission to orbit the moon -- for a cool $100 million. Previously best known for sending Dennis Tito and Mark Shuttleworth on $20 million week-long forays to the International Space Station, Space Adventures also offers somewhat more down-to-earth options, including bare-bones zero gravity training at about $5,000, or a flight on the edge of space for about $102,000.
