Journal 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

Weather, Volume 81, Issue 10, Page 337-341, October 2026.The English language is a gargantuan, gluttonous beast. It has become extraordinary in its powers of assimilation – such that we rarely consider the origins of the words we use. In this paper, we will shed light on these origins, including the Pontic–Caspian steppe, the British Empire and, of course, a TV show.

Journal of Contingencies and Crisis Management, Volume 34, Issue 3, September 2026.ABSTRACT It has been 40 years since Charles Perrow published the landmark work Normal Accidents ([1984]1999), built largely on an analysis of the Three Mile Island (TMI) nuclear power plant accident. While still a highly influential framework in the study of complex systems, the status of the argument remains in flux.

Effects of Comet Encke's Meteoroid Stream on the Seasonal Variation of Mercury's Ca Exosphere
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Mercury's calcium (Ca) exosphere, observed by NASA's MESSENGER mission, exhibits high temperatures (>50000 K) and pronounced seasonal variability, with its source mainly on the dawn side. Enhanced Ca emission near True Anomaly Angle (TAA) ∼25° and ∼150° has been attributed to Comet 2P/Encke meteoroid streams.

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract High‐altitude optical meteors initiating above 150 km are exceedingly rare, with confirmed observations largely confined to the Leonids. Using the Meteor and ionospheric Irregularity Observation System, we recorded a bright 43‐Cassiopeiids fireball with heterogeneous material. It initiated luminously at an exceptional altitude of 157.8 ± $\pm $

Transport of Water in a Transient, Impact‐Generated Atmosphere on Mercury
Journal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.Abstract Mercury's polar cold traps host water ice deposits that are likely populated with impact‐delivered water via Mercury's exosphere. However, Mercury's near‐sun location experiences an extremely high photodestruction rate that rapidly destroys water with a timescale of only ∼3.5 hr.

Archives of impact: The politics of craters on Earth
Geographical Research, Volume 64, Issue 2, May 2026.This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Journal of Geophysical Research: Planets, Volume 131, Issue 3, March 2026.Abstract From 1974 to 1975, the Mariner 10 spacecraft studied Mercury's environment during three flybys and detected hydrogen, helium, and possibly atomic oxygen in the exosphere using its ultraviolet spectrometer, but no molecular hydrogen. Based on the sensitivity of the occultation instrument, an upper limit for the H2 ${\mathrm{H}}_{2}$ surface ...

Evidence of an Extended Alfvén Wing System at Enceladus: Cassini's Multi‐Instrument Observations
Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.Abstract We report in situ evidence for Enceladus' Alfvén wing system and its coupling with Saturn's ionosphere, based on multi‐instrument observations from the Cassini spacecraft. Analysis of 36 events, including 13 from non‐flyby paths, confirms the existence of a Main Alfvén Wing (MAW) current system generated at Enceladus, and associated Reflected ...

Constructed Response Paragraph Jigsaw Puzzle Test for Measuring Structure Building Ability
Applied Cognitive Psychology, Volume 40, Issue 1, January/February 2026.ABSTRACT This study examined whether paragraph jigsaw puzzle (PJP) test can be used to measure structure building ability, the ability to construct cohesive mental representations. We developed a constructed‐response version of the PJP test and scored it with a string‐similarity algorithm that allows for partial credit.
