1. 1. Ion and ENA precipitation onto the upper atmosphere of Venus : Estimate of precipitation maps using data from a hybrid model

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Lorenzo Obersnel; [2023]
   Keywords : Eneregetic Neutral Atoms; Venus; Ion precipitation; ENA precipitation; Atomi Neutri Energetici; Venere; precipitazione di ioni; precipitazione di atomi neutri; Energisk Neutral Atom; Venus; Utfällningen joner; Utfällningen Energisk Neutral Atom;

   Abstract : Venus does not have a strong intrinsic magnetic field as the Earth, and its magnetosphere is induced by the interaction of the solar wind with the ionosphere. The near-Venus space environment is characterized by the presence of a bow shock and of an induced magnetic boundary linked to the interplanetary magnetic field orientation. READ MORE

3. 2. Definition and evaluation of a system for measuring local geomagnetic variations : Autonomous station for magnetic measurements

   University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Author : Viktor Olsson; [2023]
   Keywords : Local Geomagnetic Variations; Fluxgate Magnetometer; Space Weather; Solar Wind; Magnetic Measurements; Variometer; Solar Activity.; Lokala geomagnetiska variationer; Fluxgate-Magnetometer; Rymdväder; Solvinden; Magnetiska Mätningar; Variometer; Solaktivitet.;

   Abstract : Earth is under constant influence of the Sun and phenomena driven by the solar wind that may affect man-made technology. These events are summarized under the concept of space weather. This creates variations in Earth’s magnetic field and nearby space. Space weather can affect power grids, gas pipelines and also have effects on human health. READ MORE

4. 3. Methods for Co-Orbital Threat Assessment in Space

   University essay from KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

   Abstract : Systems for space are a challenge to construct. By creating the right requirements, the probability of creating the desired systems is increased. This thesis investigates the information flow between the NewSpace company Unibap, and their customers, concerning environment requirements, operational scenarios, and mission objectives. READ MORE

6. 5. Spatially resolved gene expression profiling of mouse brain tissue to study the impact of spaceflights

   University essay from KTH/Proteinvetenskap

   Author : Paula Frieberg; [2021]
   Keywords : spaceflight; space biologu; Spatial Transcriptomics; mouse brain tissue; mitochondria;

   Abstract : Since the first human spaceflight in 1961, hundreds of humans have been in space. Microgravity and high radiation are the main spaceflight hazards. The space environment is known to impact several aspects of human health, such as bone density and cognitive performance. READ MORE
