                         velocity solar wind represents an adverse space weather conditions 
                         hazardous for manned and unmanned space missions. During the 
                         maximum solar activity, many elements of the natural space 
                         environment can damage space missions. Low energy plasmas charge 
                         spacecraft surfaces and cause arc discharges. High-energy 
                         electrons (>2MeV) penetrate the spacecraft and build high charges 
                         in insulation on coaxial lines and circuit boards. Protons 
                         (>50MeV) and other charged particles disrupt computer memories or 
                         even damage the semiconductors structure. Spacecraft damage also 
                         includes decreased power production by solar arrays, failure of 
                         sensitive electronics, increased background noise in sensors, 
                         until radiation exposure to the crew members. The geomagnetic eld 
                         in uences the particles motions within the Earth's orbital 
                         environment and de ects incoming high-energy particles associated 
                         with cosmic rays. In the South Atlantic Magnetic Anomaly (SAMA) 
                         the Van Allen radiation belt comes closest to the Earth's surface 
                         increasing these kind of space mission damage. When solar activity 
                         is high, ultraviolet radiation from the Sun heats and expands the 
                         Earth's ionosphere, increasing atmospheric drag and orbital decay 
                         rate of spacecraft. This work presents Space Weather phenomena 
                         measurements correlating the EUV and X-ray radiation, the 
                         ionospheric and magnetospheric perturbation and space mission 
                         failures for high-intensity solar events. For this purpose, 
                         analysis were performed for the riometer, to measure the 
                         ionosphere density, and magnetometers, to measure the SAMA 
                         geomagnetic intensity, installed at the Southern Space Observatory 
                         (SSO/CRS/CCR/INPE { MCT), (29:4 oS, 53:8 oW, 480m a.s.l), S~ao 
                         Martinho da Serra, RS, Brazil, near 1 the SAMA center. To identify 
                         and monitor the sudden radiation increase the X-ray data (0.1 to 
                         0.8nm) from GOES Satellites and the EUV data (26.0 to 34.0nm and 
                         0.1 to 50.0nm) from the Solar EUV Monitor (SEM) on the SOHO 
                         spacecraft were correlated. GOES electron ux >2MeV and GOES proton 
                         ux >50MeV were measured as the particle in uences. The work also 
                         reviews space mission failures correlating Satellites and
