More to our point, lunar surface ejecta can potentially be accelerated completely off of the Moon and into the space environment! With just 1/6 th (16%) of the Earth’s surface gravity, ...

Modelling the electromagnetic emission of kilonovae enables the mass, velocity and composition (with some heavy elements) of the ejecta from a neutron-star merger to be derived from the observations.

"The impact could pose some danger to equipment or astronauts on the moon, and certainly to satellites and other ...

When a vending-machine-sized spacecraft hit Dimorphos in 2022, planetary defense experts anticipated an easy test of kinetic ...

How does a planetary defense mission intended to push an asteroid off course manage to release a torrent of boulders with the same momentum as the spacecraft? NASA’s groundbreaking experiment, the ...

These images, showing ejecta around the impacted near-Earth asteroids, were taken during the approach (with Didymos to the upper left) and departure (Didymos to the upper right) of DART's companion ...

University of Maryland astronomers discovered that an unexpected blast of space rocks ejected during DART mission carried ...
