On the 15th anniversary of the Challenger accident:

That we are able to mark this in flight, in space -- is a most fitting tribute to the memories of our fallen crewmates and friends…Today we are working and living in space -- a new era, a new enterprise -- the permanent presence of humans away from planet Earth…

Our need to explore and to fulfill the human potential defines us. Space is austere, harsh, unforgiving -- but as logical a place for us to be as any path that man ever walked. It is "high ground" for the human experience. Let the name "Challenger" give us pause to reflect on, and purpose to continue--our voyage of exploration and discovery.

Expedition One crew,
