A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

An exploration of market mechanisms to the wicked problem of space debris 太空垃圾棘手问题的市场机制探究 Una exploración de los mecanismos del mercado para resolver el complejo problema de los desechos espaciales

Risk, Hazards &Crisis in Public Policy, Volume 16, Issue 3, September 2025.
Abstract Near‐earth orbits are becoming congested because of a rapid growth in the number of satellites and space debris, which presents a real threat to the sustainable use of space and the safety of the Earth. Despite space scientists and public policymakers having been actively seeking solutions for decades, solving the problem has been put off ...

Deep Learning‐Based Automated Segmentation of Layered Crater Ejecta on Mars

Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.
Abstract Layered crater ejecta (LCE) with fluidization on Mars is generally believed to be related to the near‐surface ice‐bearing deposits. The improvement in the resolution of planetary image data has led to the discovery of more and more LCE, providing support for further research on the formation and geological significance of layered ejecta ...
