  1. 1. Design of the control system for a powered landing maneuver of a rocket

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Davide Demartini; [2023]
    Nyckelord :;

    Sammanfattning : The powered soft landing of a spacecraft represents a maneuver with high interest, withsome private launcher companies – SpaceX, Blue Origin, Rocket Factory Augsburg, etc. - showinginterest in implementing it as a solution for their launchers, and several national agenciesusing it for the exploration of celestial bodies where it may be the only option.

  3. 2. Benchmark on ground operations for reusable space launch vehicles, and support to the design of CALLISTO operations via 3D representation

    Master-uppsats, KTH/Lättkonstruktioner, marina system, flyg- och rymdteknik, rörelsemekanik

    Författare :Benoît Logiou; [2022]
    Nyckelord :Reusable launch vehicle; Vertical Takeoff Vertical Landing; CALLISTO; Ground Operations; 3D simulation; Unity; Återanvändbar raketer; Vertikal Start Vertikal Landning; CALLISTO; Markoperationer; 3D-simulering; Unity;

    Sammanfattning : This master thesis aims in first instance to provide insights about the groundoperations that are carried out by different space players in order to exploit theirreusable space launch vehicles. The CNES is currently developing the CALLISTO flightdemonstrator with the objective of demonstrating the recovery and reuse capabilityof a vertical take-off and landing vehicle, for the benefit of future operational systemdevelopments.

    Sammanfattning : For 500 years transient light phenomena (TLP) have been observed on the lunar surface by ground-based observers. The actual physical reason for most of these events is today still unknown. LÄS MER

  7. 5. Manned Mission to Mars: Water as Radiation Shielding During a Solar Particle Event

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Edda Lína Gunnarsdottir; [2020]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : "Space agencies and privat e companies are working hard to solve the various challenges that need to be overcome to take humans to Mars . The journey to Mars has mult ifaceted risks for the crew, includin g radiation exposure. One risk factor that could jeopar dize t he crew's healt h is the radiation dose from a !arge solar partide event (SPE) .. LÄS MER
