NASA satellite falls safely.

Defunct satellite RHESSI is expected to enter Earth's atmosphere today, April 19.

The American satellite was retired in 2018 and has been orbiting Earth since.

RHESSI observed solar flares and coronal mass ejections from low-Earth orbit.

NASA predicts reentry time with low risk of harm to anyone on Earth.

Most of the spacecraft is expected to burn up during reentry.

Some components are expected to survive reentry.

RHESSI was launched to image high-energy electrons from solar flares.

It recorded X-rays and gamma rays from the sun with an imaging spectrometer.

RHESSI provided crucial data on solar flares and their coronal mass ejections.

Understanding these events is crucial due to their potential effects on electrical systems.
