Abstract: "Micrometeorites are extraterrestrial dust particles that survive atmospheric entry to be recovered from the Earth's surface. These particles are the fastest dust on Earth, experiencing velocities of more than 11 km/s. Combining observations of real micrometeorites with numerical models of atmospheric entry helps us understand their formation."

The two moons of Mars, Phobos and Deimos, were first thought to be asteroids captured by the red planet. The remote sensing of their surfaces argue in favor of this scenario but the present near-circular and near-equatorial orbit of the two moons could not fit expected orbits of capture objects. An alternative scenario has been proposed in which the two small moons of Mars were formed after a giant collision occurred more than 4 billions years ago, similarly to the formation of our Moon. But this scenario raises challenges as how to form small moons (and not a big one as for the Earth) and to maintain them in orbit around Mars over billions of years.
The 2016 “Solvay Prize” is awarded to Dr. Bert Wouters (promotor Prof. dr. S. Eeltink) for his work on groundbreaking research on the development of a microfluidic chip for spatial three dimensional chromatography.
