This is Scientific American's 60-Second Science. I'm Steve Mirsky. Got a minute?

"My area of operations is 73 trillion cubic miles."

隐藏原文=

Gen.John Hyten. He leads the U.S.Air Force Space Command.

点击显示原文

隐藏原文=

He's counting all the space between the earth's surface and geosynchronous orbit, about 22,200 miles up at the equator.

点击显示原文

隐藏原文=

General Hyten visited Scientific American's offices February 26th.

点击显示原文

隐藏原文=

One area of discussion was the task of keeping the busy space above our planet free of dangerous and costly collisions.

点击显示原文

隐藏原文=

"You have to know exactly what is going on, exactly when it's going on, you have to able to predict potential hazardous collisions and you have to be able to predict threats.

点击显示原文

隐藏原文=

And you have to do that real time.

点击显示原文

隐藏原文=

So one of the reasons that we're building capabilities like improved ground-based telescopes…

点击显示原文

隐藏原文=

we're building space-based space surveillance systems…and then we have geosynchronous space situational awareness program satellites…

点击显示原文

隐藏原文=

that will move around the geosynchronous belt, giving us exquisite understanding of exactly what is in the geosynchronous belt, which is the most expensive real estate.

点击显示原文

隐藏原文=

"Then the other thing the United States has decided to do is that we're going to take all that information and we're going to bring it all together and we're going to process it,

点击显示原文

隐藏原文=

we're going to do it with our allies…partner that capability, and then if we see any collision, we're going to tell whoever that owner/operator is, whether it's us, the commercial sector, Inmarsat, Intelsat, or even if it's a Chinese or Russian satellite, we're going to tell them.

点击显示原文

隐藏原文=

"And one of the interesting things that's happened in the last few months is that we used to have to tell the Chinese through the State Department,

点击显示原文

隐藏原文=

where we would see a potential collision involving a Chinese satellite, we'd be concerned and we'd provide the information, we'd send it to the State Department, the State Department would go to the Chinese Ministry and the Chinese Ministry would then go, who knows what happened after that.

点击显示原文

隐藏原文=

So a few months ago, the Chinese came and said we'd like to be able to receive that data directly into our operations center.

点击显示原文

隐藏原文=

And we said, we'll do that.

点击显示原文

隐藏原文=

"So four or five times now we've had potential Chinese issues and we send it right into China.

点击显示原文

隐藏原文=

People get concerned about, are you giving away critical information.

点击显示原文

隐藏原文=

No, we're protecting ourselves.

点击显示原文

隐藏原文=

We're protecting that environment.

点击显示原文

隐藏原文=

I can't tell you how bad debris in space would be, especially in the geosynchronous belt.

点击显示原文

隐藏原文=

We cannot have debris in that orbit.

点击显示原文

隐藏原文=

So we have got to make sure we do that.

点击显示原文

隐藏原文=

So it's in our interest."

点击显示原文

隐藏原文=

Thanks for the minute, for Scientific American's 60-Second Science. I'm Steve Mirsky.
