Chinese rocket booster and dead Soviet satellite are one a collision course in space

If that happens, the collision could produce thousands of pieces of space debris, the most since an active communications satellite operated by Iridium and a dead Russian satellite crashed into each other in 2009 some 500 miles over Siberia.

In addition to a couple thousand operational satellites, there is a lot of trash in space — spent satellites and old rocket boosters, the flotsam of previous collisions and military maneuvers, such as when China shot down a dead satellite with a missile in 2003.

The more junk in space, the greater the possibility of additional collisions, which in turn would produce even more debris, further exacerbating a problem that is growing worse.

“Every week we see close approaches, where derelict satellites, rocket bodies, are passing within 100 meters of each other,” said Daniel Ceperley, LeoLabs’ founder and CEO. “This isn’t like this happens once a year. This happens multiple times a week. It’s sort of a ticking time bomb that’s just out there in space.”

He said the chance of a collision was less than 10 percent, but added “that’s extremely high for the space industry. At one in 10,000, a satellite operator will move their satellite. At one in 1,000, it’s is considered an emergency.” He said the company would know within a “couple of hours” whether there is a collision or not. And he said the probability of a collision could change as the objects get closer, and the company gathers more data.

So far this year, the International Space Station has had to maneuver three times to avoid debris, NASA said. Speaking at a Senate Commerce Committee hearing recently, NASA Administrator Jim Bridenstine lamented the growing problem and said the in addition to the times the station has had to maneuver there “were three potential [collisions] that made us very nervous.”

The challenge, he said, is “we don’t have as a nation, or even as a world, a robust architecture for how we’re going to integrate all of these capabilities into this small space. And it’s becoming more and more of a problem.”

The concerns come as companies such as SpaceX and Amazon are vying to launch thousands of satellites to low-Earth orbit where they would beam the Internet to rural and underserved communities. Over the next 10 years, more than 50,0000 satellites could be launched, according to Analytical Graphics Inc., a company based outside of Philadelphia that also tracks spacecraft and debris. The Pentagon tracks about 22,000 pieces of debris larger than about four inches, but scientists say there are nearly 1 million larger than half an inch. With all floating around in orbit, AGI estimates that there could be as many as 404 collision and 17 million close calls in the most congested orbits over the next decade.

That is fueling a push in some quarters, including the White House, for a civilian agency, namely the Commerce Department to take over the job of tracking debris and issuing warnings. But that effort has moved slowly,
