The commander and the pilot of last month's Space Shuttle Discovery flight will travel to Morton Thiokol's Wasatch Operations, west of Brigham City, on Monday to personally thank company employees for redesigning the shuttle's booster rockets and making them safe.

Mission commander Richard O. Covey and pilot Frederick Hauck led the first shuttle mission since the Challenger disaster that killed seven astronauts in 1986. That disaster was blamed on defects in Thiokol-made boosters.Covey, an Air Force colonel, and Hauck, a Navy captain, are scheduled to appear at Morton Thiokol during the lunch hour. They will be accompanied by Garn and Gov. Norm Bangerter on their election-eve visit.

Snow said the two astronauts are scheduled to arrive in Salt Lake City Sunday evening.
