  1. 1. Calibration and preparation of the data analysis of the DORN experiment on board the Chang'E 6 lunar mission.

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

    Författare :Íñigo de Loyola Chacartegui Rojo; [2023]
    Nyckelord :Radon; lunar mission; alpha spectrometry; space instrumentation; performance testing and validation;

    Sammanfattning : As part of the first agreement between the French (CNES) and the Chinese (CNSA) space agencies in terms of space exploration, the DORN instrument will fly on board the Chinese Chang'E 6 mission in 2024. It aims to measure the amount of Radon escaping from the lunar soil to better understand what governs the concentration of this noble gas which contributes to the endogenous origin of the lunar exosphere.

  3. 2. Design and Evaluation of an Automated Pyro Cutter System for Stratospheric Balloons

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

    Författare :Leia Nummisalo; [2023]
    Nyckelord :Stratospheric balloons; PCB; Recovery system; CNES; pyro cutter;

    Sammanfattning : This thesis describes the development of an autonomous recovery system for stratospheric balloons, focusing on the novel pressurised balloon prototype BALMAN of CNES. Stratospheric balloons, reaching altitudes of up to 40 km, are utilised for scientific experiments, with recovery of payloads being a critical aspect. LÄS MER

  4. 3. Implementation and Characterisation Testing of a PCDU for Nanosatellites

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Nyckelord :Electrical engineering; Testing; PCDU; Nanosatelllites; EPS; Power Management; Software Development; Hardware Development;

    Sammanfattning : Satellite power management systems play a crucial role in ensuring the operational success andlongevity of satellite missions. As satellites operate in the harsh environment of space, efficient powermanagement is essential to maximize energy utilization, maintain stability, and extend mission lifespans. LÄS MER

  5. 4. Optimisation of a LOX/Ethanol rocket engine ignition

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Pierre Collard; [2022]
    Nyckelord :;

    Sammanfattning : For more than half a century, humanity has achieved the feat of extracting itself from the earth's atmosphere and sailing into space, broadening the spectrum of knowledge and curiosity. Although space market seemed mastered and stable the arrival of new private players has reorganized the sector through new technological choices. LÄS MER
