Artemis 2 faces fiery Earth reentry en route to Pacific splashdown

Artemis 2's crew—Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen—will return from the moon by plunging into Earth’s atmosphere at about 23,840 mph (38,367 kph) around 75 miles up, in a roughly eight-minute fiery reentry before a splashdown in the Pacific off San Diego on April 10. To reduce heat-stress after Artemis 1’s heat-shield damage, Orion will enter at a steeper angle and rely on its Avcoat heat shield, with parachutes deploying to slow the capsule for a Navy recovery after touchdown.

Seismic Signals Pinpoint Reentering Space Debris

Ground seismic networks can detect the sonic wake of falling space junk and reconstruct its reentry path; the approach was demonstrated with the 2024 Shenzhou-15 module, revealing its speed, descent trajectory, fragmentation, and the likely debris field, offering a new tool for space situational awareness and hazard mitigation.

"SpaceX's Starship: From Successful Launch to Indian Ocean Mishap"

SpaceX's Starship rocket's recent flight showcased unprecedented footage of atmospheric reentry, made possible by the company's innovative use of Starlink satellites for communication. This achievement is a testament to SpaceX's revolutionary approach to spaceflight, which has included the development of reusable rockets like the Falcon 9 and the deployment of a vast network of Starlink satellites. These advancements are paving the way for a future where space launch is cheap and abundant, fundamentally changing the landscape of space exploration.

"29-Year-Old European Satellite Reenters Earth's Atmosphere Over Pacific Ocean"

A European satellite, ERS-2, launched in 1995 to observe Earth, reentered the Earth's atmosphere over the North Pacific Ocean after being retired in 2011, with most of its debris burning up and the rest falling into the sea. The satellite, which provided crucial data on climate change and natural disasters during its 16-year mission, was deliberately brought down to avoid adding to space debris, and experts confirmed that the chance of its debris harming humans was extremely low.

"Uncontrolled European Satellite Predicted to Crash Through Earth's Atmosphere Today: What to Expect"

The European Space Agency's ERS-2 satellite, weighing 2.3 tons, is expected to make an uncontrolled reentry into Earth's atmosphere, with some parts likely to survive the plunge. The exact time and location of the reentry is uncertain, but the latest prediction suggests it will occur at 10:41 a.m. EST on Feb. 21. The uncertainty in the prediction is primarily due to unpredictable solar activity affecting Earth's atmosphere density. While most of the satellite is expected to burn up, some parts are likely to survive, with a potential splashdown in the ocean. This event underscores the need for enforceable orbital debris regulation to support sustainable space exploration and scientific investigation.

"Imminent Crash: Dead European Satellite Hurtling Towards Earth"

After 16 years in orbit, the defunct ERS-2 satellite is expected to crash back to Earth this month, with the European Space Agency predicting that any debris will likely land in a body of water due to Earth's surface being 70% water. The satellite, which has been slowly descending since its retirement in 2011, is about the size of a city bus and weighs over 5,000 pounds. The increasing amount of space junk in Earth's orbit, including defunct satellites and small fragments of rockets or satellites, poses a growing concern for space agencies.

"European ERS-2 Satellite's Imminent Earth Reentry After 13 Years in Space"

The European Space Agency's (ESA) European Remote Sensing 2 (ERS-2) satellite, launched in 1995 and retired in 2011, is expected to reenter Earth's atmosphere later this month after a 13-year fall. The satellite, which has been maneuvered to reduce collision risk, will break apart and most fragments will burn up in the atmosphere. The risk of human injury from space debris is extremely low, and ESA will provide updates on the reentry process.
