CAPE CANAVERAL, Fla. (AP) - A group of 150 people who follow NASA on Twitter are headed to the Kennedy Space Center for two days of activities.
      
The "Tweetup," as it's known, begins on Monday in advance of Wednesday's scheduled shuttle launch. Participants were randomly selected from about 2,700 who signed up online. They'll get a tour, as well as front-row seating for Discovery's liftoff.
      
West Melbourne resident Krissy Guttendorf has watched plenty of shuttle launches over the years, but from a distance. This time she'll be about three miles from the launchpad, which she says is "unbelievable."
      
NASA says it expects to hold other such Tweetups in the future.
