Solar activity, in the form of coronal mass ejections and corotating interaction regions, results changes solar wind that propagate out through system interact with magnetic field environments planets. Such phenomena have been observed to affect plasma around Mars as seen from orbit. However, no surface observations previously possible because absence ground-based instrumentation. Here, for fir...

The term space weather is used for the solar driven variability in particle and electromagnetic conditions of the near-Earth space that may harm the performance of ground-based and space-borne technology. The European Union (EU) and the European Space Agency (ESA) have started a common programme called the Global Monitoring for Environment and Security (GMES). Many of the GMES operational servi...

São discutidos nesse artigo alguns conceitos básicos relacionados ao clima espacial no ambiente próximo da Terra. Devido ao desenvolvimento tecnológico dos anos recentes, o clima espacial tornou-se um tema importante de pesquisa. Os avanços da área se devem principalmente à sua aplicabilidade nos sistemas tecnológicos tanto no espaço próximo quanto na superf́ıcie da Terra. Dentre os diversos tem...
