  1. 1. Ageing process analysis of solar panels in graveyard geostationaryorbit for reusability potential

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Robin Drevet; [2024]
    Nyckelord :space debris; Spacecraft Materials; satellite; Space Sustainability; Space Circularity; Space Manufacturing;

    Sammanfattning : The constant growth of space debris and the associated risks force the space community to find solutions to mitigate them. Today the most advanced solutions to dispose of satellites and rocket stages after the end of mission consists of moving them either into a graveyard orbit or towards an atmospheric re-entry ending in the demise of both spacecraft and its materials.

  3. 2. Investigation of Antenna Radomes in Low Earth Orbits

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Mathias Manohar Gren; [2023]
    Nyckelord :Materials; Science; Space; Satellites; Antenna Radomes; Beyond Gravity; Coatings; Physics; Chemistry; Low Earth Orbits; Engineering; Lunds University; Materials Chemistry; Technology and Engineering;

    Sammanfattning : Introduction: This master’s thesis focuses on exploring improved alternative material solutions for antenna radomes used to protect Beyond Gravity Sweden’s satellite antennas in low Earth orbits. Background: As the environment in low Earth orbit is harsh, surface materials on satellites experience high levels of atomic oxygen, ultra violet radiation, thermal-fluctuation, charged particles and micro meteoroids.

  4. 3. Improving the understanding of photoelectron currents on Solar Orbiter : Utilizing theory and empirical measurements

    Kandidat-uppsats, Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Melker Marminge; [2023]
    Nyckelord :Solar Orbiter; Photoelectric Currents; Photoelectric Effect; Thermal Bending; Outgassing; Thermionic Emission; Numerical Approximation; Physical Modeling;

    Sammanfattning : Spacecraft experience electric currents on conductive materials exposed to sunlight, which introduces noise in scientific data. These currents are mainly due to the photoelectric effect and should therefore be proportional to the inverse square heliocentric distance. LÄS MER

  5. 4. Analysis and Design of a Microgravity Drop Tower

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Tristan Edwards; [2023]
    Nyckelord :drop tower; microgravity;

    Sammanfattning : A drop tower is a device that produces a microgravity environment by allowing an experiment to free fall for a short period of time, usually less than 10 seconds. Certain types of drop towers are also capable of reproducing the gravitational conditions of other celestial bodies, such as Lunar and Martian gravity. LÄS MER

  7. 5. Small Satellite Design for High Sensitivity Magnetic Measurements

    Master-uppsats, Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Författare :Noel Sebastian Janes; [2022]
    Nyckelord :Magnetic Cleanliness; FORESAIL; CubeSats; High Sensitivity Magnetic Measurements; Small Satellite;

    Sammanfattning : The magnetic cleanliness of a spacecraft during magnetic measurements is an important aspect in the design of many space science missions. The adequate reduction or removal of the spacecraft's magnetic disturbance plays a vital role in allowing the ambient magnetic field to be measured with the required accuracy. LÄS MER
