We remember the men and woman of the Challenger - who 25 years ago this day gave their lives not just for our nation but for the benefit of all humankind.
Let us keep their families and colleagues in our prayers as we seek new ways to reach for the stars. Part of the human experience is to explore and it is vitally important that we develop new international efforts to visit Mars and to learn more about the creation of the cosmos. Today, however, it is right to pause in memory of these American heroes. Those of us who lived that day will never forget their sacrifice.
