The Benefits of High Resolution Multispectral TIR Data and Its Impending Loss by NASA After Four Decades

open access: yesPerspectives of Earth and Space Scientists, Volume 7, Issue 1, December 2026.
Abstract NASA has led multispectral (≥3 wavelength bands) thermal infrared (TIR) sensor development from the earliest days of the agency. These data are critical in addressing a wide range of scientific questions and administration priories by measuring both temperature (for wildfire and volcanic eruption monitoring, agricultural plant stress, and ...

Assessment on the feasibility of future shepherding of asteroid resources [PDF]

open access: yes, 2010
Most plausible futures for space exploration and exploitation require a large mass in Earth orbit. Delivering this mass requires overcoming the Earth's natural gravity well, which imposes a distinct obstacle to any future space venture.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

Automatic Crater Classification Using a Deep‐Learning‐Based Pipeline

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 5, October 2026.
Abstract Identifying and classifying impact craters on Mars is crucial for understanding the planet's geological history and surface evolution. Traditional crater classification relies on manual annotation methods, which are often limited by human biases and the difficulty of interpreting geomorphological features.

Probing Subsurface Properties With Mission Hardware: Lessons Learned From Artificial Impacts of Mars 2020

open access: yesGeophysical Research Letters, Volume 53, Issue 18, 28 September 2026.
Abstract Hardware released during spacecraft entry can generate hypervelocity impacts that provide unique constraints on planetary subsurface properties. During NASA's Perseverance descent, two tungsten cruise ballast mass devices (CBMD) and fragments of the cruise stage formed meter‐scale craters north‐west of Jezero crater, in one of the sinuous ...

Ferric Chloride: The Venusian Unknown UV Absorber?

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 9, September 2026.
Abstract Near‐ultraviolet imaging of the planet Venus reveals inhomogeneous absorption features in the otherwise bright clouds. This absorption has been studied for nearly 100 years, but identification of the near‐UV absorber remains one of the largest open questions in Venusian research.
