NASA’s Webb Telescope Confirms Asteroid 2024 YR4 Will Safely Pass the Moon in 2032
Infrared observations from the James Webb Space Telescope refined the orbit of asteroid 2024 YR4, confirming it will safely pass about 21,200 km above the Moon in December 2032. The new data eliminates earlier estimates that suggested a small chance of a lunar impact.

Mars Orbiter Tracks Interstellar Comet 3I/ATLAS With Unprecedented Precision
Scientists mapped the path of interstellar comet 3I/ATLAS with ten times greater accuracy using images from ESA’s Mars orbiter. The breakthrough shows how observations from different points in space can improve future planetary defense. The data, the first of its kind from another planet’s orbit, offers a powerful new tool for tracking fast-mov...

NASA Shuts Down Public Communications on Website Amid US Budget Impasse
NASA’s online presence has gone dark as a U.S. budget lapse forces a government shutdown. Outreach, research, and grant work have stopped, while critical ISS and planetary defense operations persist. The silence recalls 2013’s shutdown, which caused widespread delays to missions and scientific projects.

Astronomers Reveal Sudden Explosion of Small Asteroid Over France
In February 2023, asteroid 2023 CX1 exploded suddenly over France, stunning scientists. Tracked only hours before impact, the tiny rock disintegrated in a powerful airburst, scattering meteorites across Normandy. The rare event provides crucial insights into asteroid behavior and raises new considerations for future planetary defense strategies.

Massive Boulders Ejected by DART Mission Could Complicate Future Asteroid Deflection
NASA’s DART mission successfully deflected an asteroid but also unleashed high-velocity boulders with unexpected momentum. These chaotic ejecta may alter asteroid spin and orbit, complicating future deflection strategies. A new study highlights the importance of accounting for such forces in planetary defence. ESA’s Hera mission will further in...

NASA Slightly Raises Odds of Asteroid Hitting the Moon in 2032 After Updated JWST Data
NASA has revised the 2032 impact odds of asteroid 2024 YR4 hitting the Moon to 4.3%, up from 3.8%, based on new data from the James Webb Space Telescope. Though once feared for its high Earth impact risk, scientists now say it poses no threat and offers critical insights for future planetary defense strategies.

NASA Shares Planetary Defense Strategy to Protect Earth From Potential Asteroid Strikes
NASA and international scientists closely tracked asteroid 2024 YR4, which initially showed a rare 3 percent collision probability with Earth. Although the threat has now diminished, the incident highlights the importance of asteroid surveillance, open data, and upcoming space missions like NEO Surveyor.

3D Mapping Reveals 52-Foot Megaripples from Chicxulub Asteroid in Louisiana
Massive megaripples, formed by the tsunami after the Chicxulub asteroid impact 66 million years ago, have been mapped deep beneath Louisiana using 3D seismic data. The formations, averaging 52 feet in height and spanning 900 square miles, offer new insights into the force of the ancient tsunami and its global impact. Scientists suggest these findin...

NASA Partners With SpaceX To Launch NEO Surveyor, a Mission To Detect Asteroid Threats
NASA has selected SpaceX for the launch of its NEO Surveyor spacecraft in 2027. The mission, valued at $100 million, will use a Falcon 9 rocket to deploy the spacecraft to the Sun-Earth Lagrange Point 1. The infrared telescope will help detect and track hazardous near-Earth objects, including difficult-to-spot dark asteroids. This mission builds on...
