Debris in low Earth orbit adds to hazards of space exploration
One major obstacle to human space exploration is the possible limitations imposed by the adverse effects of long-term exposure to the space environment. Even before human spaceflight began, the potentially brief exposure of astronauts to the very intense random solar energetic particle (SEP) events ...
Space debris (SD) has been accumulating for 64 years, since 1957 with the launch of Sputnik 1. Since then, numerous factors have added to the SD section of the United States Air Force Space Command (USAFSC) space object catalog. SD is defined as any type of space object particularly: in...
