Course Aim

The student shall acquire knowledge about the space environment, especially concerning its influence on problems for space-crafts and its instruments, as well as methods to mitigate the induced problems. This is shown by ability to describe the space environment and estimate the complex of problems with vehicles in space.

The student shall be able to describe and analyze the space environment and its influence on the spacecraft with its components. This is shown by performed hand calculations on a mathematical and physical basis. The student shall be able to use specific computer programs as a tool for describing the space environment and analyze and calculate its influence on the spacecraft with its components.

The student shall be aware of the uncertainties and limitations, e.g. as a consequence of the solar activity, that are associated with vehicles in space. The student shall be aware of the possible negative consequences with satellites in space, as e.g. space debris.This is shown by valuation of associated questions.


Contents

The space environment: solar radiation and solar wind, low temperatures, vacuum, atomic oxygen, atmospheric drag, orbital debris and micrometeoroids, plasma, and radiation. Effects on the spacecraft: outgassing, contamination, chemical reactions, atmospheric drag force, erosion, sputtering, glow, particle collisions, spacecraft charging, radiation influence in different wavelength bands, deep dielectric charging, influence on electronic circuits and living tissues.

Specific program SPENVIS is used in the course to calculate the space environment in satellite orbits and its influence on the spacecraft with its components.


Realization
Lectures, exercise classes and computer laboratory exercise. In the practical, which preferably is done in group of two students, an open problem is treated that are presented in a written report.

In the practical is computer program used that is also used by the space industry. Guest lecture who has worked with astronauts and cosmonauts.


Examination
Written examination and laboratory report. In order to pass the course it is required that all examinations and obligatory tasks are completely satisfactory. The written exam is graded with 5, 4, 3, and Fail(U), while the written laboratory report is graded with Approved (G) and Fail (U). The course is then graded with 5, 4, 3, and Fail (U). Borderline cases for approval of the written exam have the possibility of obtaining bonus points from the written laboratory report.

Remarks
Advanced level. This course gives the foundation for the demands that must be put on construction of a spacecraft in order for it to work in space. Thus it gives the ground for the course R7019R Spacecraft subsystems.
