             abstract = "The SCD-1 and SCD-2 satellites were launched in 1993 and 1998, 
                         respectively, with use of the Launcher Pegasus of the OSC (Orbital 
                         Sciences Corporation). 21 and 16 years later, the satellites are 
                         still in orbit around the Earth and providing data for users. 
                         Mission and Operational data from Satellite Tracking Center 
                         Network are stored in mission files in the Satellite Control 
                         Center (SCC) and made available to the users. The SCC also stores 
                         history files of the satellite orbit and attitude ephemeris, 
                         besides the on-board telemetry, temperatures, equipment status, 
                         etc. This work will present some analysis of the orbit ephemeris 
                         evolution based upon the Two-Line Elements sets (TLE´s) obtained 
                         from NORAD (North American Aerospace Defense Command). Attitude 
                         evolution along time is also presented for both satellites from 
                         SCC data. The orbit decay will be explained as resulting mainly 
                         due to the solar activity during the satellite lifetime. This work 
                         aims to report the history of more than 20 years of continuous 
                         operation of SCD-1 and SCD-2. At the end, an estimation of the 
                         orbital decay is forecast with the use of NASAs DAS software.",
