We’ve had things that have reentered have a 1 in 1,000 chance, and nothing happened; if we have a few that are 1 in 4,000 or 5,000, it’s not a horrible day for mankind,” Dr. Darren McKnight, a senior technical fellow at space-tracking company LeoLabs,

A long-retired NASA satellite has finally returned to Earth, burning through the atmosphere before falling into the Pacific.

The satellite, launched 14 years ago, will make an uncontrolled re-entry Tuesday evening. NASA puts the risk of harm to anyone on Earth at "approximately 1 in 4,200."

It’s a homecoming to rock your world. A 1,323-pound spacecraft is expected to rip through Earth’s atmosphere Tuesday night, warns NASA of the incoming juggernaut. “The U.S. Space Force predicted that the [satellite] will re-enter the atmosphere at approximately 7:45 p.

An old NASA science satellite is no more. The U.S. Space Force says the Van Allen Probe A plunged uncontrolled from orbit on Wednesday, reentering over the Pacific west of the Galapagos Islands.

Sunspot AR4618 erupted with an M4.4-class solar flare causing a coronal mass ejection (CME) that may give Earth a glancing blow. NASA's Solar Dynamics Observatory captured the fireworks in multiple wavelengths.

NASA is keeping an eye on near-Earth objects. One such object is a small asteroid called 2026 FB. This asteroid is expected to pass close to the Earth today. The asteroid is small in size, but it is still keeping the attention of experts.

NASA's Tandem Reconnection and Cusp Electrodynamics Reconnaissance Satellites (TRACERS) mission will study "magnetic reconnection and its effects in Earth's atmosphere," according to the Goddard Space Flight Center.
