The Effect of Tip Design on Technological Performance During the Exploration of Earth, Lunar, and Martian Soil Environments

Journal of Field Robotics, EarlyView.
ABSTRACT This paper investigates the penetration performance of soil‐burrowing probes with different tip designs during shallow‐depth penetration in various media, including terrestrial soils (Hostun sand) and well‐characterized planetary soil simulants (LHS‐1 Lunar regolith simulant and MGS‐1 Martian regolith simulant).

A Systemic Reflection On Why Biology Is Best : E(s) ∞$$ \infty $$ mc2 Sentience, Consciousness and Transcendance?

Systems Research and Behavioral Science, EarlyView.
ABSTRACT The short essay makes a case that a post biological world will be a devolution. Sentience is a relational process linked with the awe and wonder we experience in relation to one another and our shared habitat. The voiceless need to be protected by extending solidarity on the basis of sentience—a normative plea, but also on the basis of ...

A Post‐Launch Summary of the Science of NASA's Psyche Mission

AGU Advances
Astronomical observations indicate that asteroid (16) Psyche is a large, high‐density (likely >3,400 kg·m−3), metal‐rich (30–55 vol. %) asteroid. Psyche may be remnant core material or it could be a primordial, undifferentiated metal‐rich object.

Episodes of particle ejection from the surface of the active asteroid (101955) Bennu

Science, 2019
Bennu ejects material from its surface Most asteroids appear inert, but remote observations show that a small number experience mass loss from their surfaces. Lauretta and Hergenrother et al.

Erosive Hit-and-Run Impact Events: Debris Unbound

, 2015
Erosive collisions among planetary embryos in the inner solar system can lead to multiple remnant bodies, varied in mass, composition and residual velocity. Some of the smaller, unbound debris may become available to seed the main asteroid belt.

EU Space Law and Earth's Boundaries: Integrating Environmental Impact Assessment and Corporate Due Diligence

Global Policy, EarlyView.
ABSTRACT The European Union's proposed Space Law aims to establish a unified approach for sustainable space activities across the EU. While the EU's satellite constellations contribute to sustainability efforts, they can also have negative environmental impacts.
