Old NASA satellite set to fall to Earth, risk 'low'

NASA said Tuesday that the spacecraft's re-entry location was not being disclosed, due to uncertainty about when and where it might crash.

Most satellites weighing less than 660 pounds (300 kg) will burn up upon re-entry into the atmosphere, but some parts are thought to survive.

The risk of anyone on Earth being harmed by falling satellite fragments is “low,” the space agency NASA said in a statement.

Rhessi - short for Reuven Ramaty High Energy Solar Spectroscopic Imager - launched into orbit in 2002 to study the Sun.

Before being decommissioned in 2018 due to communications problems, the satellite observed solar flares as well as coronal mass ejections from the Sun.

It took high-energy X-ray and gamma-ray images, recording more than 100,000 solar events during its mission.
