A proposal for control system of a wind energy convertion system for special purposes [PDF]

, 2011
Nuclear energy sources have been widely used in the past decades in order to power the spacecrafts, nevertheless their use has attracted controversy because of the risk of harmful material released into the atmosphere if an accident were to occur during ...

Reconfigurable Intelligent Surface Deployments for Mars: Communication and Localization Across Diverse Terrains

IEEE Open Journal of the Communications Society
Space exploration has witnessed a steady increase since the 1960s, with Mars playing a significant role in our quest for further knowledge. As the ambition to colonize Mars becomes a reality through the collaboration of private companies and space ...

Numerical Simulations of 3D Scattering Structures Reveal Systematic Underestimation of Marsquake Magnitudes

Geophysical Research Letters, Volume 53, Issue 17, 16 September 2026.
Abstract Determining marsquake magnitudes is essential for assessing seismic activity on Mars, yet previous estimates neglect three‐dimensional (3D) scattering effects. The exceptionally long‐lasting coda of the largest recorded marsquake, S1222a, provides a unique opportunity to quantify how crustal heterogeneities affect waveform propagation and ...

Ozone Detector Based on Ultraviolet Observations on the Martian Surface

Remote Sensing
Ozone plays a key role in both atmospheric chemistry and UV absorption in planetary atmospheres. On Mars, upper-tropospheric ozone has been widely characterized by space-based instruments.

Stationary flux ropes at the southern terminator of Mars [PDF]

, 2012
Flux ropes have long been observed in the upper atmosphere of Venus, and more recently at Mars. Here we present magnetic field measurements of flux ropes encountered at the southern terminator of Mars by Mars Global Surveyor, and compare them to a flux ...

Photogrammetric co-registration and photometric analysis of HRSC Phobos images [PDF]

, 2012
HRSC images from Mars Express Phobos flybys are used to study the photometric character of the surface of the Martian satellite. This investigation involves measuring of surface reflectance and illumination angles for estimates of a phase curve, and ...

Acoustic Propagation in the Near‐Surface Martian Atmosphere

Journal of Geophysical Research: Planets
Abstract This work introduces a comprehensive model of sound propagation on Mars, in light of the recent operation of several microphones on the Martian surface. The main outcome of this work is an operational acoustic model capable of simulating the sound field created by any source, at any location on the ...

Plasma-based conversion of martian atmosphere into life-sustaining chemicals: The benefits of utilizing martian ambient pressure

Journal of CO2 Utilization
We explored the potential of plasma-based In-Situ Resource Utilization (ISRU) for Mars through the conversion of Martian atmosphere (∼96% CO2, 2% N2, and 2% Ar) into life-sustaining chemicals.
