Reconstructing Digital Elevation Models From Single Synthetic Aperture Radar Images
Abstract Traditional radar‐based methods of generating topography involve complex dual‐antenna or formation‐flying satellite configurations, interferometric processing, and specialized expertise. We present an approach for reconstructing digital elevation models (DEMs) from single Synthetic Aperture Radar (SAR) images using deep learning.

Terrestrial Analogs to Titan for Geophysical Research
Abstract Saturn's moon Titan exhibits remarkable parallels to the Earth in many geophysical and geological processes not found elsewhere in the solar system at the present day. These include a nitrogen atmosphere with a condensible gas—methane—replacing the Earth's water, leading to an active meteorology with rainfall and surface manifestations ...

Terrestrial Space Weather Protection Through Human‐Produced Mass‐Loading
Abstract While humans become more reliant on Earth's space environment, the potential for significant harm from severe space weather continues to grow. As structures from the sun reach Earth's magnetosphere and space environment, they deposit energy that fuels geomagnetic storms.

Reinvestigating the Nightside Ionosphere of Mars With 8 Years of Mars Express and MAVEN Data
Abstract Tailward ion escape in the nightside magnetotail is one of the dominant paths of ion escape from Mars. The Martian nightside ionosphere can serve as a major reservoir for this escape channel, but its global distributions and dependence on the upstream solar wind have not been fully investigated due to observational limitations.

This golf ball is designed to be used in Martian gravity. As Martian gravity is weaker than Earths, this golf ball feels heavy when held on Earth. It forms part of an ongoing project by Bethany Rigby on Golf and outer space, developing a speculative ...

Massive clouds erupted 260km into Martian atmosphere – and no one knows why [PDF]
First paragraph: Enormous cloud-like plumes reaching 260km above the surface of Mars have left scientists baffled. This is way beyond Mars’s normal weather, reaching into the exosphere where the atmosphere merges with interplanetary space.

Identification (or otherwise) of martian carbon in martian meteorites [PDF]
One of the goals of current martian exploration is to search for evidence of extinct (or even extant) life. In recent years, this goal has been interpreted as a search for evidence of water on Mars’ surface. The success of instrumentation (high resolution cameras and infrared spectrometers) on orbiting spacecraft, coupled with in situ data from the MER

Mastcam‐Z Spectrophotometric Properties of Materials at the Van Zyl Overlook, Jezero Crater
Abstract During Sols 63–65 of Mars 2020, Mastcam‐Z multispectral (442–1022 nm) images were acquired at Van Zyl Overlook (VZO), spanning phase angles from ∼0° to 150°, to model photometric parameters for seven surface units. These units included rocks, soils, regolith, and rover tracks near the Jezero landing site.

The exploration of Mars would heavily rely on Martian rocks mechanics and engineering technology. As the mechanical property of Martian rocks is uncertain, it is of utmost importance to predict the probability distribution of Martian rocks mechanical ...
