NASA satellite crashes to Earth, location and impact unknown.

A 600-pound NASA satellite, RHESSI, is expected to crash back into Earth's atmosphere on Wednesday night, but the location of where it will hit is unknown. NASA expects most of the spacecraft to burn up as it reenters the atmosphere, but some components are expected to make it through and hit Earth. The risk of it causing harm to anyone on Earth is low, with odds of approximately 1 in 2,467. NASA and the Defense Department will continue to monitor reentry and update predictions.

NASA satellite crashes in Sahara Desert

NASA's RHESSI solar flare satellite, launched in 2002, disintegrated over the Sahara desert after plummeting into Earth's atmosphere. The 660-pound spacecraft spent 16 years studying highly-energetic particles ejected from the Sun during intense outbursts caused by the release of magnetic energy. Although mostly burnt up, some components of the space junk may have survived the journey and could be scattered somewhere over the Sahara desert. RHESSI observed the Sun longer than its 11-year solar cycle and recorded over 100,000 solar flares, providing scientists with clues on how the Sun generated coronal mass ejections.

NASA satellite crashes to Earth over Sahara Desert.

An old NASA satellite, Rhessi, fell to Earth over the Sahara Desert after nearly 21 years in orbit. While most of the 660-pound satellite was expected to burn up while tumbling through the Earth's atmosphere, NASA had anticipated some pieces would survive the fall. The agency said they had received no reports of damage or injury from the spacecraft. Rhessi observed solar flares from its low-Earth orbit up until its decommissioning in 2018 following a communication problem. During its mission, Rhessi recorded more than 100,000 X-ray events, helping scientists to learn more about the energy of solar flares.

NASA satellite crashes in Sahara Desert.

NASA's RHESSI satellite, which was launched in 2002 to study the sun, reentered Earth's atmosphere and crashed over the Sahara Desert on April 19. Most of the spacecraft burned up, but some pieces were expected to make it to the ground. RHESSI was just one piece of the more than 30,000 pieces of space junk currently being tracked in Earth's orbit.

NASA's Retired Satellite Set to Re-Enter Earth's Atmosphere with Potential Risk to Humans

An old NASA satellite named Rhessi, which was launched in 2002 to study the sun, is expected to fall to Earth this week. The risk of harm to anyone on Earth is low, with a 1-in-2,467 chance of being hit by plunging satellite pieces. Most of the 660-pound satellite is expected to burn up upon return, but some parts may survive. Rhessi observed solar flares and coronal mass ejections from the sun before being shut down in 2018 due to communication problems.

NASA's Retired Sun-Studying Satellite Set to Crash into Earth with Risk to Humans

The Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI), a 660-pound NASA spacecraft launched in 2002 to study solar flares and coronal mass ejections from the sun, is set to crash onto Earth on Wednesday after being retired in 2018 due to communications difficulties. NASA says the risk of harm to people on Earth is low, and most of the spacecraft will burn up upon re-entry, but some components are expected to survive. RHESSI recorded more than 100,000 X-ray events and helped improve measurements of the sun's shape.

NASA satellite RHESSI set to crash into Earth with low risk of danger.

A 660-pound NASA satellite, RHESSI, is expected to re-enter Earth's atmosphere on Wednesday, after spending more than 20 years in space. The spacecraft is expected to burn up as it re-enters the atmosphere, but some components are expected to hit Earth. The location of where it will hit Earth is unknown, but the chances of it causing harm to anyone on Earth are low, with odds of approximately 1 in 2,467. NASA and the Defense Department will continue to monitor reentry and update predictions.

NASA satellite's Earth crash risk low, chance of harm 1 in 2,467.

An old NASA satellite named Rhessi is expected to fall to Earth this week, but experts say the risk of danger is low. The satellite, which was launched in 2002 to study the sun, observed solar flares and coronal mass ejections before being shut down in 2018. Most of the 660-pound satellite is expected to burn up upon reentry, but some parts may survive. The risk of anyone on Earth being harmed by falling satellite pieces is about 1-in-2,467.

NASA's Defunct Satellite Set to Crash to Earth Soon.

The retired NASA spacecraft, Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI), is expected to reenter Earth’s atmosphere on April 19, after years of providing scientists with valuable data about solar flares. The 660 pound (300 kilograms) satellite will likely burn up during its reentry, although some parts could survive the atmospheric plunge and make their way to the surface. NASA reassured the people of Earth, however, that the risk of harm is approximately 1 in 2,467.
