1. 1. Wheel-terrain contact angle estimation for planetary exploration rovers

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Ria Vijayan; [2018]
   Nyckelord :Contact angle; Side slip angle; Nonlinear Kalman filter; Differential Kinematics; ExoMars BB2; Planetary exploration rovers;

   Sammanfattning : During space missions, real time tele-operation of a rover is not practical because of significant signal latencies associated with inter planetary distances, making some degree of autonomy in rover control desirable. One of the challenges to achieving autonomy is the determination of terrain traversability. LÄS MER

3. 2. 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.

4. 3. Scheduling Strategies for Relay of Mars Rover Data via Mars Orbiter and Earth Stations

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

   Författare :Jendrik Jördening; [2016]
   Nyckelord :Mars Relay Network; ExoMars; Pass Scheduling; ExoMars 2020; ExoMars; RSP;

   Sammanfattning : In this thesis, the relay communication between landed assets on the surface of Mars via a relay orbiter to Earth is studied for its latencies and the times which can be provided for the landed asset to work and for the ground to plan depending on the operational margins, the available ground station network and the available relay orbiters. In this context, an automated solver is developed to evaluate a locally optimal strategy of relay pass assignment respecting the different constraints and is proven to provide a solution close to the globally optimal one.

5. 4. Field-Site Prototype for HABIT (FSP-HABIT) : Characterizing Martian Salts Prior to the ExoMars 2020 Mission

   Master-uppsats, Luleå tekniska universitet/Rymdteknik

   Författare :Johannes Güttler; [2016]
   Nyckelord :Mars; Brine; Perchlorate; Chloride; HABIT; ExoMars; ESA; IKI; Prototype; Conductivity; BOTTLE ENVPACK; Salt;

   Sammanfattning : One of the major remaining question about Mars is its habitability - if the requirements necessary to allow for life are presently fulfilled. One of the most relevant ingredients for life, as we know it, is water. Indirect evidence of transient liquid water on Mars has been retrieved from both rover [Martín-Torres et al. LÄS MER
