Welcome to Luciano Iess's Homepage
On the left: the JUNO mission (NASA) was launched on 5 agosto 2011 e and it will be orbited around Jupiter in 2017. Its main purposes are the study of the atmosphere and of the interna structure of the planet. On the centre: artist view of the Cassini and Huygens probes at Saturn. On the right: Saturn almost at equinox, as seen from Cassini (ISS Cassini).

IMPORTANT ANNOUNCEMENT: All exams planned for Sept. 4, 5, and 6 Sept. (first session of the fall semester) are CANCELLED. I decided to take part in the protest of university professors. I will be available on 4 Sept. to explain the reasons of my decision.
You will find on Infostud a new session on 2 October.
----------------------------------------------------------------
Space Missions and Systems:
Students admitted to the exam in "Easy Mode"
Correction to Homework#2:
In the first part of the test, the angular momentum storage capacity is ± 523.6 N-m-s, NOT ± 5236 N-m-s.
Answers to emails received
There is no preferred method to solve the problems. You are completely free to use the tools you master better.
We cannot give any indication on how to solve the problems, or to let you know if you are doing things right.
The initial conditions in the second part of the test are the same as in part 1.
Second homework: Download the text (pdf) here.
Email a working computer code (Matlab, Python, Fortran 77 or 90 or 96, C or C++) and a short note (in pdf!) with the mathematical procedure, results, comments and figures by Tuesday May 30 23:59:59 UTC to luciano.iess@uniroma1.it AND mircojunior.mariani@uniroma1.it . In the note indicate your FIRST NAME, LAST NAME, AND STUDENT ID (aka “numero di matricola”). Be concise and go straight to the point.
Challenge 2016-2017: Results
Benedicter 3 pt

*** Space Missions and Systems 2016/2017 - Homework #1:
Click here to download the test.
The solution (a pdf file) and the source code must be emailed by Sunday April 9 23:59:59 CEST to luciano.iess@uniroma1.it AND mircojunior.mariani@uniroma1.it. 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.
