Ref 2345-2020

Luleå University of Technology is experiencing strong growth with world leading competence in several areas of research. Our research is conducted in close collaboration with industries such as Bosch, Ericsson, Scania, LKAB, SKF and leading international universities. Luleå University of Technology has a total turnover of SEK 1.8 billion per year. We currently have 1,700 employees and 15,100 students.

We shape the future through innovative education and groundbreaking research. Drawing on our location in the Arctic region, we create global societal benefit.

Northern Sweden is a European space region with several major players collaborating in space technology and space science. Luleå University of Technology provides research and education, the Swedish Institute of Space Physics (IRF) focuses on research and instrument development, and the Swedish Space Corporation (SSC), with its facility Esrange, provides services and infrastructure for access to space.

The Department of Computer Science, Electrical and Space Technology seeks a PhD student to contribute to our growing activities. The position is located at the space technology division, in Kiruna. The Space Technology division offers a number of degree programs at advanced level, for example a national 5 year MSc program on Space science and technology and an international SpaceMaster program in collaboration with several other universities. The division conducts research in the field of atmospheric science and space systems. Within atmospheric science, the focus is on studying planetary atmospheres and developing instruments for planet exploration. In onboard space systems, research is conducted on systems for observation, instrumentation, communication and manipulation in the upper atmosphere, in space and on planetary objects. Our research and education is supported by high-quality infrastructure such as our lab for small satellites, NanoSat Lab. The lab provides access to state-of-the-art equipment and installations for manufacturing, integration and environmental hardware-in-the-loop (HIL) design and simulation, as well as a ground station for controlling miniature satellites. The lab has recently been used in the development of a 2U cubesat for the entire cycle of design and development for the international project QB50.

The Atmospheric Science division is searching for a PhD student in the subject of Planetary and Space Sciences to explore physical properties of asteroid materials. The successful candidate will be part of a vibrant research group exploring asteroids, comets and planets, with numerous involvements in space missions led by ESA, NASA and JAXA. You will acquire unique knowledge and skills and will be part of a creative research environment in collaboration with international teams of scientists.

Project description
Our understanding of solar system minor bodies is currently evolving rapidly, based on data from JAXA’s Hayabusa2 and NASA’s Osiris REX missions. One of the most significant findings was that the regolith on asteroid Ryugu was considerably more frail than previously thought, although this was deduced indirectly, mainly from visible and infrared data. Importantly, we now believe that there are no analogues for Ryugu’s regolith in our meteorite collections. These observations motivate two science themes to be addressed in this project.

  • How do these frail regolith beds originate? Are they remnants from the early stages of solar system accretion or the result of (possibly on-going) fracturing processes? Based on recent spacecraft data and using state-of-the-art techniques, this project will determine if, and under which circumstances, a process known as thermal fatigue can become a dominant process in the production of regolith and modification of boulder surface layers on various solar system bodies.
  • How are thermal and mechanical properties of regolith related? What methods and mechanisms can be used to directly measure regolith mechanical properties rather than inferring them from thermal measurements? The science return of a spacecraft surface sampling system will be explored by investigating measurement strategies and geometries in a variety of materials and settings. LTU is part of JAXA’s next minor bodies mission MMX, which will take a sample of the surface of Mars’ moon Phobos, which will be an opportunity to directly apply the techniques studied.

Duties
You will work in the above project and participate in space mission data analysis or preparation as required. You will develop your skillset through courses and carry out dissertation work reviewing literature, examining and developing theoretical models, planning and conducting laboratory experiments, analysing laboratory and space mission-related data, synthesising experiments and theory and disseminating your results in journal articles, at international conferences and at team meetings. The research subject is multidisciplinary and includes aspects of physics, geology and engineering. Teaching and other duties at the division and / or department exist for graduate students, which is limited to a maximum of one year of the total period not exceeding five years.
