COTS for Deep Space Missions

, 2019
The usage of commercial off-the-shelf (COTS) technologies in (deep) space missions might be a risk for the mission. But sometimes radiation tolerant parts are not feasible due to space or performance requirements. This paper gives a brief overview of the usage of COTS in (deep) space missions at the DLR Institute of Robotics and Mechatronics and ...

The Radiation Impact of Solar Energetic Particle Events on the Moon: A Statistical Study Using Data‐Based Modeling Results

Space Weather
The Moon lacks a global magnetic field and atmosphere, leaving its surface been directly exposed to high‐energy cosmic radiation. Sporadic Solar Particle Events are sources of a significant radiation exposure, potentially posing serious threats to the ...

Self‐Consistent Optimization of Electron and Neutral Densities in a Physics‐Based Model Toward Ionosphere‐Thermosphere Forecast

Space Weather
In this study, we aimed to explore whether electron and neutral densities could be simultaneously optimized while keeping the ionosphere‐thermosphere (IT) system self‐consistent.
