Scientists have identified the Bennu asteroid threat as the highest single-date impact probability for any known asteroid.

Solar radio bursts are intrinsically linked to the motion of their emitting source through the coronal and heliospheric plasma. Electron transport is mostly confined to magnetic field lines. These ...

One of the main challenges of desert rail operations is maintaining functional track and ballast. Professor Hannes Gräbe of the Chair in Railway Engineering at the University of Pretoria explains how ...

The "NEO Hunter" mission would use Blue Origin's Blue Ring spacecraft to deflect space rocks. This plan builds on NASA's successful DART mission, which proved an asteroid's path could be altered.

GXBeam is a pure Julia implementation of Geometrically Exact Beam Theory, originally based on the open source code GEBT and its associated papers[1] [2], though it has since been augmented with a ...

Abstract: Accurate characterization of surfaces using cantilever-based optical beam deflection (OBD) systems is crucial for obtaining the sample’s “true” topography and its corresponding material ...

NASA’s DART mission, the first-ever planetary defense test in space, sent a spacecraft to crash into an asteroid in 2022. That mission was a success. It showed that, in a hypothetical scenario where a ...

Millions of asteroids orbit the Sun. Smaller fragments often brush the Earth’s atmosphere to light up the sky as meteors. Once every few centuries, a meteoroid has sufficient size to cause regional ...
