Credit: NASA NASA recently received its first sample of asteroid Ryugu, which was returned to Earth last December by the Japan Aerospace Exploration Agency’s (JAXA) Hayabusa2 spacecraft. This is one of the first samples to leave Japan for preliminary investigation. As deputy leader of the mineralogy-petrology subteam for the preliminary analysis effort, Mike Zolensky […]

Using data from several instruments onboard Rosetta, CASTRA’s team has modeled the properties of cometary dust in the environment of Comet 67P. Image credit – ESA/Rosetta/NAVCAM As anyone who has ever tried to clean a home knows, ridding yourself of dust is a Sisyphean effort. No surface stays free of […]

This artist’s concept depicts the asteroid Psyche, the target of NASA’s Psyche mission.

The widely studied metallic asteroid known as 16 Psyche was long thought […]

A standoff detonation of a nuclear device irradiates an asteroid and deposits energy at and beneath the surface. In this work, two neutron yields (50 kt and 1 Mt) and two neutron energies (14.1 MeV and 1 MeV) were the primary case studies compared side-by-side. The black dots represent the […]

This artist’s concept shows the planned flight path of NASA’s OSIRIS-REx spacecraft during its final flyby of asteroid Bennu, which is scheduled for April 7. Credit: ASA/Goddard/University of Arizona NASA’s OSIRIS-REx mission is on the brink of discovering the extent of the mess it made on asteroid Bennu’s surface during last fall’s […]
