In spite of my request to send me an email if you can't or do not wish to take the exam, I did not receive any notification from the following students:
PRASHANT GUGLOTH
POOJA LAL HARI
MAHENDER JUMIDI
SIMONE PALUZZI
DIPENDRA SHAH
ALI ASGHAR SYED
ANDREA BROCCOLETTI

CHIARA BLANCHE WIEDECK DI LUCA
This is unpolite and very irritating. 60 s of your time will help me and everyone to better plan our time.
----------------------
47 students signed up for this session (23 Space Environment - SE, 24 Space Missions & Systems - SMS). We will meet in front of my office at 9:00 for the Multiple Choice Test (MCT). We will start with SMS, then SE. Depending on the outcome of the Multiple Choice Test, it is likely that some of the SE exams will be moved to Monday morning.
13 Sept.: MCT at 9:00, teacher's office (SE students and SMS students not qualifying for exams in "easy mode".)
13 Sept.: Space Missions and Systems (SMS) - Start at 10:00, teacher's office.
13 Sept.: Space Environment (SE) - Start not before 15:00, teacher's office. Exams could perhalps continue on Sept. 16.
Should you decide not to take the exam, send me an email by 14:00 Thursday 12 Sept. No shows mess up the planned sequence of exams. They are extremely unpolite to the other students and very irritating.

**** Space Missions and Systems 2018/2019 - Homework #2:
The following students failed HW#2:
1618530 1555375 1593651 1645570 1694047 1836659 1851492 1879048

Students marked with an asterisk (*) marginally passed the HW#2. This indicates a barely sufficient comprehension of the topics addressed in the problem. The (*) does not compromise access to the exam in "easy mode".
Students who wish to take the exam in June and did not pass both homeworks (or the Challenge and homework#2) must take the Multiple Choice Test tomorrow 5 June at 9:00.
NEW: Latest version of the slides uploaded (28/5/2019)
NEW: Work and stage opportunities - see link on the left. (21/5/2019).
**** Space Missions and Systems 2018/2019 - Challenge
Winners:
2 points: Proietti, Musacchio
1 point: Leonardi, Tramutola, Collettini
Congratulations to the winners and all participants! There were many good solutions. My collaborators and I are very happy of the overall outcome, as the problem was not easy. Unfortunately nobody assigned the correct weights to the data, so the first prize (3 points) could not be awarded.
The challenge is a valid replacement for Homework #1 for:
Carfora, Coppola, Farisei, Ferrari, Giuliani, Lambertini, Lisi, Pianalto.
Please take note of the changes - (5 May 15:36)
