[00:00.000 --> 00:08.000] My fellow Americans, this day has brought terrible news and great sadness to our country.
-[00:08.000 --> 00:17.000] At 9 o'clock this morning, Mission Control in Houston lost contact with our Space Shuttle Columbia.
-[00:17.000 --> 00:24.000] A short time later, debris was seen falling from the skies above Texas.
-[00:24.000 --> 00:29.000] The Columbia's lost. There are no survivors.

+[00:23.000 --> 00:29.000] The Columbia's lost. There are no survivors.
[00:29.000 --> 00:32.000] On board was a crew of seven.
-[00:32.000 --> 00:43.000] Colonel Rick Husband, Lieutenant Colonel Michael Anderson, Commander Laurel Clark, Captain David Brown, Commander William McCool,
-[00:43.000 --> 00:52.000] Dr. Kultner Aschavla, and Elon Ramon, a Colonel in the Israeli Air Force.

+[00:48.000 --> 00:52.000] a colonel in the Israeli Air Force.
[00:52.000 --> 00:58.000] These men and women assumed great risk in the service to all humanity.
-[00:58.000 --> 01:06.000] In an age when space flight has come to seem almost routine, it is easy to overlook the dangers of travel by rocket
-[01:06.000 --> 01:12.000] and the difficulties of navigating the fierce outer atmosphere of the Earth.
-[01:12.000 --> 01:22.000] These astronauts knew the dangers, and they faced them willingly, knowing they had a high and noble purpose in life.
-[01:22.000 --> 01:30.000] Because of their courage, endearing, and idealism, we will miss them all the more.
-[01:30.000 --> 01:40.000] All Americans today are thinking as well of the families of these men and women who have been given this sudden shock and grief.
-[01:40.000 --> 01:45.000] You're not alone. Our entire nation agrees with you.
-[01:45.000 --> 01:52.000] And those you love will always have the respect and gratitude of this country.

[01:52.000 --> 01:56.000] The cause in which they died will continue.
-[01:56.000 --> 02:07.000] Mankind is led into the darkness beyond our world by the inspiration of discovery and the longing to understand.
-[02:07.000 --> 02:11.000] Our journey into space will go on.

[02:11.000 --> 02:16.000] In the skies today, we saw destruction and tragedy.
[02:16.000 --> 02:22.000] Yet farther than we can see, there is comfort and hope.
-[02:22.000 --> 02:31.000] In the words of the prophet Isaiah, "Lift your eyes and look to the heavens who created all these.
-[02:31.000 --> 02:39.000] He who brings out the starry hosts one by one and calls them each by name."
-[02:39.000 --> 02:46.000] Because of his great power and mighty strength, not one of them is missing.
-[02:46.000 --> 02:55.000] The same creator who names the stars also knows the names of the seven souls we mourn today.
-[02:55.000 --> 03:05.000] The crew of the shuttle Columbia did not return safely to Earth, yet we can pray that all are safely home.
-[03:05.000 --> 03:14.000] May God bless the grieving families and may God continue to bless America.
