Aerospace experts are monitoring a large section of a rocket which is expected to fall back to Earth on Saturday.

It's not clear when or where it will land, however.

This section is part of a Long March 5B rocket, launched by China on July 24, to deliver a laboratory module to China's Tiangong Station.

Rocket debris is usually meant to be returned to earth in a controlled manner, often into the ocean to avoid densely populated areas.

The 23-metric-ton rocket booster was launched and is currently being dragged towards Earth for uncontrolled reentry.

Aerospace Corporation is a non-profit that offers technical guidance for space missions to commercial, military, and civil customers.

Experts said that it is impossible to determine the exact location where the rocket booster will enter the Earth's atmosphere. This can be done within hours.

Both of the previous Long March 5B rocket launches had uncontrolled reentries.

"The problem is that the density in the upper atmosphere changes with the time there is actually weather up there.

Rocket debris was found near the West Coast of Africa in 2020, and the Indian Ocean in 2021.
