Abstract:Due to the space plasma and the Sun, spacecraft at geosynchronous Earth orbit can charge naturally negative tens of kV. This charging can cause arcing which can damage spacecraft electronics and solar panels. A charged spacecraft will also experience a perturbative force and torque due to Earth's electric and magnetic fields. These electromagnetic perturbations have recently been postulated to cause significant orbital changes for lightweight debris objects. This paper investigates the effects of electromagnet… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
