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.

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.
