1. 6. Methods to operate and evaluate the performance of a cold-gas CubeSat propulsion system on a magnetically stabilised satellite

   Master-uppsats, KTH/Rymdteknik

   Författare :Victor Alberto Gonzalez Marin; [2020]
   Nyckelord :Propulsion system; CubeSat; Performance; Operating procedure; Mission experiment; Framdrivningssystem; CubeSat; Prestanda; Driftsrutin; Driftprov;

   Sammanfattning : Propulsion systems allow satellites to perform many functionalities in space, such as orbital station keeping, reentry control, attitude control, orbital transferring, rendezvous operation, and even more thrilling, interplanetary travel. Indeed, propulsion systems in satellites have fostered a new favourable era of space exploration and application, therefore, detailed processes to operate propulsion systems need to be developed so that space missions, carrying this valuable system, are completed successfully.

3. 7. Image simulations of the mission Martian Moons eXploration

   Master-uppsats, KTH/Rymdteknik

   Författare :Romain Domagala; [2020]
   Nyckelord :;

   Sammanfattning : Martian Moons eXploration is a JAXA-lead mission aiming at exploring the moons of Mars, Phobos and Deimos. The hyperspectral infrared camera provided by France should perform global mapping of Phobos at high resolution in order to characterize surface composition and therefore help determine the origins of the moons.

4. 8. Geometrical and Perturbative study of Tidally Deformed Schwarzschild Spacetime

   Master-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Zeyd Sam; [2020]
   Nyckelord :;

   Sammanfattning : Vi undersöker tidvattendeformationen av ett icke-roterande, så kallade Schwarzschild, svarta hål. Vi formulerar geometrin i form av inre och yttre geometriska kvantitet på händelsehorisonten, som beskrivs av en hyperyta inbäddad i rumtiden, och vi gör det genom att formulera Gauss-Codazzi teorin om nollhyperytor som sträcker det standard resultat för rumslika och tidslika fallen.

5. 9. Effects of planetary radius contraction on scattering

   Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

   Författare :Viktor Hrannar Jónsson; [2020]
   Nyckelord :Physics and Astronomy;

   Sammanfattning : The observed high orbital eccentricities of many giant exoplanets is thought to be the result of gravitational scattering between planets. Outcomes of planet-planet scattering can result in some planets being lost by ejections into interstellar space, or collisions between planets or with the star. LÄS MER

7. 10. Intake Design, and Optimization for an Atmosphere- Breathing Electric Propulsion System

   Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

   Författare :Jesus Espinosa Orozco; [2020]
   Nyckelord :Atmospheric Intake; ABEP; Electric Propulsion; Plasma; VLEO;

   Sammanfattning : Over the last two decades, Very Low Earth Orbit (VLEO) has gained researchers attention as it provides a significant amount of benefits in the field of earth observation and telecommunications. VLEO provides increased payload performance, improved geospatial accuracy, lower launch mass, simplified end of life disposal, and they reduce space-debris collision risk. LÄS MER
