Chinese rocket debris is expected to fall to Earth, Rocket Chinese review.

Chinese rocket debris is expected to fall to Earth.

Officials are tracking a section of a Chinese rocket that is expected to crash land on Earth as early as Saturday, but they have no idea where it will land.

"It's too early to tell where it's going to land," Pentagon spokesman John Kirby said in a briefing Wednesday.

The section is part of the Chinese Long March 5B rocket, which last week launched a module of the country's first permanent space station into orbit.

"We're tracking it and following it as closely as we can," Kirby explained. "It's just a little too early to tell where it's going or what, if anything, can be done about it right now."

The United States Space Command confirmed that it was "aware of and tracking" the rocket's location, but that "its exact entry point into the Earth's atmosphere cannot be pinpointed until within hours of its reentry." The FAA stated that it is "engaged" with NORAD and will "send out an advisory to any facilities that may be potentially affected."

"If necessary, tactical decisions will be made based on real-time information," the FAA stated.

The current orbital inclination "means that reentry can be as far north as Chicago, New York City, Rome, and Beijing and as far south as New Zealand and Chile," according to Aerospace.org, a nonprofit that performs technical analyses and assessments for a variety of government, civil, and commercial customers.

"This places any of those locations within the potential reentry path of this massive piece of space junk measuring 98 feet long, 16.5 feet wide, and weighing 21 metric tonnes," the group explained.

Rockets that return to Earth are typically brought back to Earth in a controlled manner into the ocean. According to one expert, it's unclear why this rocket's return to Earth is uncontrollable.

"I heard speculation that they wanted to control it and that something broke. In space, things go wrong. Space is difficult, "In an interview with ABC News, Ted Muelhaupt, CEO of the Orbital Reentry and Debris Studies Aerospace Center said.

According to the Associated Press, the Chinese government still has to comment publicly on re-entry.

"If something goes back and more than 1 in 10,000 risks, a person could be harmed," Muelhaupt said. "You then take action to alleviate that. And control of where the vehicle lands is the most frequent way. Basically, when there are no people you bring the vehicle down.
