The Highest Voice Known Speaks Out on War and Tucson Too...

Congresswoman Giffords' brother-in-law, Scott Kelly, space station commander, led NASA in a moment of silence — and struggled with the senselessness of the shooting.

Flight controllers in Houston fell silent as Scott Kelly spoke via radio from space.

"We h...ave a unique vantage point here aboard the International Space Station," he said. "As I look out the window, I see a very beautiful planet that seems very inviting and peaceful. Unfortunately, it is not."

"These days, we are constantly reminded of the unspeakable acts of violence and damage we can inflict upon one another, not just with our actions, but also with our irresponsible words," he said.

"We're better than this. We must do better." (I agree with the highest voice heard)
