Article Synopsis
- - NASA's OSIRIS-REx mission successfully collected a sample from asteroid Bennu in October 2020, with plans to deliver it to Earth in September 2023, despite challenges in finding suitable collection sites due to unexpected surface conditions.
- - A "Sampleability Map" was created to identify and evaluate potential sampling locations on Bennu based on how compatible they were with the spacecraft's sampling mechanism, using a scoring system called "sampleability."
- - The sampleability algorithm assessed surface properties on two levels: globally to understand Bennu's surface as a whole and site-specifically for higher-resolution predictions at targeted collection spots, ultimately aiding in choosing the optimal collection location.
Barrier islands are complex and dynamic systems that provide critical ecosystem services to coastal populations. Stability of these systems is threatened by rising sea level and the potential for coastal storms to increase in frequency and intensity. Recovery of dune-building grasses following storms is an important process that promotes topographic heterogeneity and long-term stability of barrier islands, yet factors that drive dune recovery are poorly understood.
