1. 1. Supersonic Retro Propulsion Flight Vehicle Engineering of a Human Mission to Mars

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Hanna Marklund; [2019]
   Nyckelord :Supersonic retro propulsion; SRP; Mars; Human mission; Inflatable heat shield;

   Sammanfattning : A manned Mars mission will require a substantial increase in landed mass compared to previous robotic missions, beyond the capabilities of current Entry Descent and Landing, EDL, technologies, such as blunt-body aeroshells and supersonic disk-gap-band parachutes. The heaviest payload successfully landed on Mars to date is the Mars Science Laboratory which delivered the Curiosity rover with an approximate mass of 900 kg. LÄS MER

3. 2. Evolution of the signal induced by ChemCam on Mars as a function of focus

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Angèle Pontoni; [2017]
   Nyckelord :;

   Sammanfattning : ChemCam, mounted on the mast of the Mars Science Laboratory (MSL) rover, uses Laser-Induced Breakdown Spectroscopy (LIBS) to perform remote-sensing science on Mars. ChemCam’s telescope is used to simultaneously focus the laser on martian rocks up to 7 meters away from the rover and collect the light emitted as the plasma plume created on the target cools down.

4. 3. LES Simulation of Hot-wire Anemometers

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

   Författare :Assiye Süer; [2017]
   Nyckelord :Hot-wire anemometer; Hot-film anemometer; Computational Fluid Dynamics; Mars Science Laboratory; MSL; Mars; Large Eddy Simulations; LES; Reynolds-Averaged Navier–Stokes equations; RANS;

   Sammanfattning : Hot wire anemometers have been used in several wind velocity sensors deployed in Mars. They are based in keeping the temperature of a surface at a constant value, above the ambient. This is done by means of a heater controlled with an electronic system. LÄS MER

5. 4. Measurement of the convective heat transfer with wind : Developing and testing an Earth Scaled Atmospheric Temperature Sensor

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

   Författare :Philipp Wittmann; [2016]
   Nyckelord :Wind; ATS; heat transfer; air temperature sensor; atmospheric temperature sensor;

   Sammanfattning :    The HAbitability, Brine Irradiation and Temperature Package (HABIT) instrument of the ExoMars Surface Platform will investigate the present day habitability of Mars at the near surface environment. This instrument includes three Atmospheric Temperature Sensor's (ATS's) which are similar to the ones previously used on the Rover Environmental Monitoring Station (REMS) of the Mars Science Laboratory (MSL) rover, that has now been operating on Mars for more than four years.

7. 5. Dark Ages Lunar Interferometer - Deployment Rover : Propulsion and Steering Systems

   Kandidat-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

   Författare :Victoria Birgersson; Maximillian Lundgren-Goodman; [2015]
   Nyckelord :NASA; DALI; rover; rymden; månen; framdrivning; styrsystem; astronomi;

   Sammanfattning : 2030 NASA Jet Propulsion Laboratory will place an interferometer, which will workas a radio telescope, on the far side of the Moon. The interferometer uses thinpolyamide films as antennas, which are rolled out by a rover (an autonomousvehicle). The thesis covers concept generation of the propulsion and steering systemof the rover. LÄS MER
