US shootings: Tragedy touches the space station

INTERNATIONAL Space Station commander Scott Kelly led Nasa in a moment of silence yesterday as he struggled with the shooting of his congresswoman sister-in-law as well as six people who were killed in the incident.

His identical twin brother, Mark Kelly, is married to Gabrielle Giffords. Both brothers are astronauts.

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

"We're better than this. We must do better."

Mr Kelly described his sister-in-law as "a caring and dedicated public servant".

He is half-way through a six-month space station mission, in charge of the six-person crew. His brother is supposed to command a shuttle flight in April; his status now is uncertain as his wife fights for her life.
