We conducted avalanching experiments with an external magnetic field and granular samples of different grain sizes (3.18 mm, 6.35 mm, and 8.

Previous work has inferred the bearing capacity and trafficability of specific regions of the Moon using orbital imagery and measurements of the boulder tracks visible on its surface. Here, we estimate the bearing capacity of the surface of an asteroid for the first time using DART/DRACO images of suspected boulder tracks on the surface of asteroid (65803) Didymos.

- Planetary defense research is heavily dependent on understanding the mechanical properties of asteroids, which are challenging to assess from Earth.
- A study of boulders on the asteroid Dimorphos, using data from the DART mission, revealed an estimated internal friction angle of 32.7 ± 2. 5°, indicating they likely formed from impact processing.
- The similarities between Dimorphos boulders and those on other rubble-pile asteroids (Itokawa, Ryugu, and Bennu) suggest a shared formation process and enhance our understanding of asteroid characteristics and the implications for planetary defense strategies.
Background And Aims: Integrating sustainability principles into medical and surgical curricula raises awareness and empowers future healthcare professionals to adopt sustainable practices, reducing the environmental impact of surgical care. This study aims to assess the presence of sustainability education in African medical schools and surgical residency curricula to inform policymakers and educators in African healthcare systems.
Methods: This cross-sectional study was undertaken through an online survey among medical students and surgical trainees in African countries to describe the presence of sustainability education in surgical training programs and medical curricula across Africa.
