1. 6. Sunshade Demonstrator Spacecraft Earth Sphere of Influence Escape Using a Propellant-free AOCS

   Master-uppsats, KTH/Rymdteknik

   Författare :Leonardo Ricci; [2021]
   Nyckelord :Solar sail; Solar radiation pressure; Attitude control; Escape trajectory; Centre of pressure; Disturbance Torques; Eclipse.; Solsegel; Solstrålningstryck; Attitydkontroll; Flyktbana; Tryckcentrum; Störningsmoment; Eclipse.;

   Sammanfattning : This thesis provides insights to what is peculiar about a solar sail attitude and orbit control system and provides the assessment, in the form of a feasibility study, of the effectiveness of sail tip vanes as a control hardware to escape the Earth sphere of influence. The demonstrator aims to prove the technology for the Sunshade project, a constellation of solar sails located at the Lagrangian point L1 to obscure part of the solar radiation directed towards earth.

3. 7. Error Injection Study for a SpaceFibre In-Orbit Demonstrator

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

   Författare :Carlos Abad Garcia; [2020]
   Nyckelord :;

   Sammanfattning : The space electronics sector is shifting towards the New-Space paradigm, in which traditional space-quali_ed and expensive components and payloads are replaced by commercial o_-the-shelf (COTS) alternatives. This change in mentality is accompanied by the development of inexpensive cubesats, lowering the entry barrie in terms of cost, enabling an increase in scienti_c research in space. LÄS MER

4. 8. 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.

5. 9. Dynamic Analysis of Sinusoidal, Random and Shock Vibration according to Launch Environment for Small Spacecraft Development to Asteroid 2016-HO3

   Master-uppsats, KTH/Lättkonstruktioner

   Författare :Akhsanto Anandito; [2019]
   Nyckelord :spacecraft; resonance frequency; sinusoidal; random vibration; shock; FEM; rymdfarkoster; resonansfrekvens; sinusformad; slumpmässig vibration; chock; FEM;

   Sammanfattning : The investment of space commerce is skyrocketing and it is predicted to be a nascent business in the future. The spacecraft demand has been growing not only for NASA and other space agency’s mission but also collaboration business between small space industries, academia, and scientific community. LÄS MER

7. 10. "Så träffades vi likafullt av spjutet" - En existentialistisk läsning av Harry Martinsons rymdepos Aniara. En revy om Människan i Tid och Rum

   Kandidat-uppsats, Göteborgs universitet/Institutionen för filosofi, lingvistik och vetenskapsteori

   Författare :Alicia Lindström; [2018-08-15]
   Nyckelord :Aniara; Existentialism; Martinson; Harry Martinson;

   Sammanfattning : Harry Martinsons berömda rymdepos Aniara. En revy om människan i tid och rum (1956) beskriver hur en grupp människor är lämnade åt sitt öde när deras rymdfarkost, tänkt att ta dem till Mars, hamnar ur kurs och far planlöst ut i kosmos. LÄS MER
