An ion-beam shepherd (IBS) is a concept in which the orbit and/or attitude of a spacecraft or a generic orbiting body is modified by having a beam of quasi-neutral plasma impinging against its surface to create a force and/or a torque on the target. Ion and plasma thrusters commonly used to propel spacecraft can be employed to produce a collimated plasma/ion beam and point it towards the body.The fact that the beam can be generated on a "shepherd" spacecraft placed in proximity of the target without physical attachment with the latter provides an interesting solution for space applications such as space debris removal, asteroid deflection and space transportation in general. The Technical University of Madrid (UPM) is exploring this concept by developing analytical and numerical control mo

| - Ioi-sorta artzaina (ISA) espazioko gorputz bat, artifizial edo naturala, desbideratzeko balia daitekeen metodo bat da. Metodo hau, gorputza desbideratzeko, kuasi-neutrala den plasma sorta bat sortzean oinarritzen da, zeinak gorputz arrotzaren gainazalaren aurka talka egitean, nahi den lekura bultzatzeko aukera ematen duen. Normalean ioi eta plasma bultzagailuak espazio ontziak propultsatzeko baliatzen dira, baina plasma kolimatu edo ioi sorta bat sortzeko eta gero hura nahi den tokira zuzentzeko erabil daitezke. Metodo honek sorta hori "artzain" espazio ontzi batean sortzea proposatzen du, zeina sorta aplikatu nahi den gorputzetik hurbil egongo litzatekeen, fisikoki eutsita egon gabe. Baliteke metodo honek etorkizunean zeresan handia izatea, adibidez, espazioko hondakinak deuseztatzen, Lurretik gertuko objektuak desbideratzen eta orokorrean, espazioko garraioa sustatzen lagun liezagukeelako. Madrilgo Unibertsitate Politeknikoa (UPM) kontzeptu hau garatzen dabil, ESAko batera, kontrol eredu tekniko eta numerikoak sortzen eta probatzen ari baita. Gainera, kontzeptu hau JAXA eta CNES erakundeek ere proposatu dute, era independentean. (eu)

The Technical University of Madrid (UPM) is exploring this concept by developing analytical and numerical control models in collaboration with the Advanced Concepts Team of the European Space Agency. The concept has also been proposed independently by JAXA and CNES. (en)
