  1. 1. 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

  3. 2. Dark Ages Interferometer (DALI) Deployment Rover: Energy System

    M1-uppsats, Högskolan i Halmstad/Energiteknik

    Författare :Gustav Andersson; Emil Ericsson; [2014]
    Nyckelord :Rover; Moon; Photovoltaics; Battery; JPL; NASA; Electric; Energy; Solceller; Månen; Batterier; JPL; NASA; Energi;

    Sammanfattning : The cosmic “Dark Ages” is the cosmic era between the epochs of recombination of cosmic microwave background and the formation of the first stars. The only signal from this epoch is from neutral hydrogen, which could represent one of the richest data sets in cosmology. LÄS MER

  4. 3. Dark Ages Lunar Interferometer (DALI): Deployment Rover

    Kandidat-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :Tobias Johannesson; Karl Hansson; [2013]
    Nyckelord :Rover; Deployment. Lunar;

    Sammanfattning : In this thesis we have looked at the possibility of using a rover for deployment of lunar interferometers on the dark side of the moon. This project was made together with two other groups at Halmstad University. The project was divided into three units and we had the main responsibility for the deployment unit on the rover. LÄS MER

  5. 4. Dark Ages Lunar Interferometer (DALI): Deployment-Rover - Mobility System

    Kandidat-uppsats, Sektionen för ekonomi och teknik (SET)

    Författare :Erik Andersson; Per-Johan Bengtsson; [2013]
    Nyckelord :Mobility system; Lunar; rover; DALI; Interferometer;

    Sammanfattning : This thesis is issued in collaboration with the Jet Propulsion Laboratory (JPL) in Pasadena, California. JPL's primary function is the construction and operation of robotic planetary spacecraft. At the time being JPL has 22 spacecraft and 10 instruments conducting active missions. LÄS MER

  7. 5. Ångström Small Radio Telescope

    Uppsats för yrkesexamina på avancerad nivå, Institutionen för fysik och astronomi

    Författare :Henrik Lindén; [2011]
    Nyckelord :radio telescope; radio astronomy; hydrogen line; radioteleskop; vätelinjen; radioastronomi; parabol;

    Sammanfattning : For the Swedish Institute of Space Physics and Uppsala University, we have developed a working radio astronomy telescope capable of receiving the 21cm hydrogen line; the Ångström Small Radio Telescope. The work have resulted in a functional system for positioning the dish, with built in tracking of deep space objects and scanning functions, and signal reception with filtering, mixing and digital sampling.
