Just an observation. NASA in the past has been very unlucky when the number 13 had something to do with a mission. And the agency has been very superstistious in recent years concerning the "curse" of number 13 by avoiding it whenever possible. With the upcoming shuttle mission, a record 13 people will lodge at Hotel International Space Station. God willing nothing goes wrong during the mission, I wonder if those superstitious ones at NASA would consider that to mean that the curse has been broken and maybe we will see the end NASA managers avoiding the use of the number 13 during planning of future missions.
