Quantitative measurements and photographic imaging of the moons of Mars set limits on
several key geological conclusions-such as the orbits of the moons. Other examples include …

Abstract The Double Asteroid Redirection Test (DART) is a NASA-sponsored mission that
will be the first direct test of the kinetic impactor technique for planetary defense. The DART …

The interior of the Martian moon Phobos has not been precisely determined yet, in spite of
space missions sent at close distance to the body. The current measurements (imagery …

The surface of Phobos is an intriguing subject of research for many scientists. This is
associated, among other things, with the fact that it is perceived as a potential launch site for …

The effects of projectile/target impedance matching and projectile shape on energy,
momentum transfer and projectile melting during collisions are investigated by numerical …

The long, shallow, parallel grooves that cut across the surface of the Martian moon Phobos
remain enigmatic, with distinct implications for understanding the evolution of loose airless …

Diverting hazardous small bodies on impact trajectories with the Earth can in some
circumstances be impossible without risking disrupting them. Disruption is a much more …

Phobos and Deimos are the only natural satellites of the terrestrial planets, other than our
Moon. Despite decades of revolutionary Mars exploration and plans to send humans to the …

Asteroids and comets have the potential to impact Earth and cause damage at the local to
global scale. Deflection or disruption of a potentially hazardous object could prevent future …

Near Earth asteroids with diameters less than 50 m possess distinct characteristics including
a large population, a high likelihood of Earth impact, and limited warning time. While small …
