Ryugu reference project: Recommendations from the measurement definition team

Meteoritics &Planetary Science, Volume 61, Issue 5, Page 819-848, May 2026.
Abstract Sample return missions play a significant role in planetary science by providing pristine extraterrestrial materials. JAXA's Hayabusa2 and NASA's OSIRIS‐REx missions have returned samples from the C‐type asteroids Ryugu and Bennu, respectively. The chemical and mineralogical compositions of these samples closely resemble those of CI chondrites,

The atmosphere of Mars and optical communications [PDF]

The effects of the Martian atmosphere on an optical communication link are analyzed using Mariner 9, Viking Orbiter, and Viking Lander data. Clouds are found to have minimal effect because of their scarcity and thinness.

Ice clouds in the Martian atmosphere

Journal of the Japanese Society of Snow and Ice, 2005
近年の探査衛星観測により火星の気象学的観測データの量が飛躍的に増加したことから,火星大気の氷雲の科学を定量的に論ずることが可能となってきた.火星のH2O氷雲は受動的トレーサであるため,その分布を調べることで直接観測が困難な火星大気の流れ場に関する情報を得ることができる.従来直接観測が困難であった極夜のCO2氷雲は,マーズグローバルサーベイヤーのレーザー高度計によりその存在が初めて明らかとなった.CO2氷雲は過去の火星の気候を考える上でも重要な要素である.過去に火星で実現していた温暖な気候を維持するには,厚いCO2大気にともなうCO2氷雲の温室効果が寄与していたのではないかと考えられているからである.CO2氷雲の形成過程と消散係数などの放射パラメータを調べることにより ...

The Dissipation Regime of Turbulence on Mars Observed With Microphone Data From the Mars 2020 Perseverance Rover

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Turbulent winds are a regular occurrence in planetary boundary layers. Turbulence affects mixing, energy fluxes and forcing on the surface environment. Energy injected into an atmosphere generates eddies of many scales down to a size where molecular viscous forces dominate, termed the Kolmogorov length scale.

Simultaneous Compressive Kinetic‐Scale Fluctuations and Second‐Harmonic Proton Cyclotron Waves Inside a Martian Magnetosheath Structure

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Mars directly interacts with the solar wind and hosts a complex plasma‐wave environment. Using MAVEN observations, we identify an event in the dusk‐side Martian magnetosheath where strongly compressive sub‐cyclotron kinetic‐scale fluctuations coexist with second‐harmonic proton cyclotron waves (PCWs).
