Earth and Planetary Physics, 2020 Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).

Martian atmospheric O3 retrieval development for the NOMAD-UVIS spectrometer [PDF]
, 2017 The composition of atmospheric trace gases and aerosols is a highly variable and poorly constrained component of the martian atmosphere, and by affecting martian climate and UV surface dose, represents a key parameter in the assessment of suitability for

Boundary Delineator for Martian Crater Instances with Geographic Information and Deep Learning
Remote Sensing, 2023 Detecting impact craters on the Martian surface is a critical component of studying Martian geomorphology and planetary evolution. Accurately determining impact crater boundaries, which are distinguishable geomorphic units, is important work in ...

Modeling Solar Proton Event-induced Martian Surface Radiation Dose [PDF]
arXiv, 2020 Solar Proton Events (SPEs) can cause abrupt and significant enhancements to the Martian surface radiation dose. Observations of the impact of SPEs on the Martian surface are available from satellites and surface detectors, but the data set is very limited in time, and the energy range is limited in scope, which makes it insufficient to estimate the ...

Rocket Cratering in Simulated Lunar and Martian Environments [PDF]
arXiv, 2023 With NASA's planned return to the moon and possibly with lunar outposts being formed, repeated landings at the same site will be necessary. Understanding rocket plume interaction with lunar and Martian surfaces is of paramount importance in order to safely land and protect hardware surrounding the landing site. This work will report on results of three

New Technology, Work and Employment, EarlyView.Abstract The proliferation of food delivery platforms is profoundly changing the way urbanites eat, work, and move. These platforms increasingly mobilise urban resources and population to function as critical infrastructure in the field of logistics and transportation, giving rise to a new form of governance.

Radiative Habitable Zones in Martian Polar Environments [PDF]
Icarus 175 (2005) 360-371, 2005 The biologically damaging solar ultraviolet (UV) radiation (quantified by the DNA-weighted dose) reaches the Martian surface in extremely high levels. Searching for potentially habitable UV-protected environments on Mars, we considered the polar ice caps that consist of a seasonally varying CO2 ice cover and a permanent H2O ice layer. It was found that,

The depth of the convective boundary layer and implications for a Walker-like circulation on Mars [PDF]
, 2011 Radio science observations indicate that the depth of the martian convective boundary layer varies strongly with surface height, although the surface temperature does not.
