Space missions and systems 2014/2015- First homework:
The solution (a pdf file) and the source code must be emailed by Sunday Apr. 19 21:59 UTC to firstname.lastname@example.org AND email@example.com. NO EXCEPTIONS!
Suggestions and remarks: Be concise and go right to the point. Plots convey information very effectively. Including a working source code is mandatory.

*** MSS test n.2:
List of received homeworks
Students admitted to the exam in simplified mode
MSS 2014 - Home test n. 2
Email the code and the report to firstname.lastname@example.org AND email@example.com by Friday May 30 23:59:59.
Students passing both home tests (or the challenge and the second test) will be entitled to take the exam in a simplified mode.
Clarification #1: you may neglect the torque variations due to the eclipses.
Clarification #2: if needed, you may use this matlab routine to solve Kepler's equation.
Clarification #3: The angular momentum storage capacity is 29.32 N-m-s and not 22.6 N-m-s.
Clarification #4: The minimum time requirement has to be intended loosely. Any design of the control system attaining the required attitude in a reasonable time is acceptable.
