Third planet of the star Impron ; Diameter 21814 Km , Gravity 2.13 g , median Rotation period 29.54 h , medium temperature 10.9 ° Celsius . " USTRAC " , being  the abbreviation of " United Stars Training Center " ,  is the main military academy of the USO , where officers are trained in their second phase . USTRAC has an irregular rotational pattern with the result that the climate and temperatures can change rapidly and stark . All imaginable situations and environmental settings can therefore be simulated and trained there . 

Universities and special learning centers are distributed over all the different simulacra . With immense financial support , even huge pressure chambers have been built where atmospheric conditions like on Methane - Ammonium gas giants like Jupiter can be simulated , as well as the broiling heat of Venus or the vast cold emptiness of Mars type planets .

Other climates range from Deserts to Mountains of altitudes of over 12.000 meters .

The entrance age for an USO Officer into the USTRAC education is no less than 27 years and the education takes between ten and thirty years , with an average of about twelve years . An absolvent of USTRAC attains the degree of " Specialist " , which is a sine - qua - non for the General Staff Academy .
