Dear Editor,I was a student at UMass/ Boston when the shuttle Challenger exploded after takeoff on January 28,1986. I clearly remember an article or column that was published right after that called “Facing the Frontier” or Facing Space” (something like that)that touched quite a few people on the campus at the time. You may want to dig up that article from your archives and run it again…it was damn good…E. StearnsUMass/BostonClass of 1987
