A major goal of future missions is to find solutions that minimize costs. Our study presents the use of solar radiation pressure, by varying the area-to-mass ratio and/or the reflectivity coefficient of the spacecraft, with the goal to assist in the ejection of the spacecraft from an orbit around an asteroid, for a possible return phase to the Earth or to direct the spacecraft to a second target. The asteroid Didymos, which has a small natural moon (Didymoon), is chosen as the focus of the present study, because it is the target of the AIDA mission. The study showed the existence of small but important escape windows from the asteroid using the solar radiation pressure to eject the spacecraft from the system. The results also showed: Survival regions between L4 and L5, with small escape regions nearby, a very large natural ejection zone 20 km away from the surface of Didymos, areas of survival near the surface of Didymos caused by resonances and the identification of a chaotic region ranging from approximately 1.2 km to 20 km from the surface of Didymos. %9 conference paper %T On the use of solar radiation pressure to eject a spacecraft orbiting the asteroid 65803 Didymos (1996 GT) %@electronicmailaddress jose.batista@inpe.br %@electronicmailaddress diogo.sanchez@inpe.br %@electronicmailaddress antonio.prado@inpe.br %@nexthigherunit 8JMKD3MGPCW/3F2UALS %@nexthigherunit 8JMKD3MGPCW/446AF4B %@secondarytype PRE PI %@usergroup self-uploading-INPE-MCTI-GOV-BR %@usergroup simone %@group DIDMC-CGETE-INPE-MCTIC-GOV-BR %@group CMC-ETES-SESPG-INPE-MCTIC-GOV-BR %@group DIDMC-CGETE-INPE-MCTIC-GOV-BR %@tertiarymark 8JMKD3MGP3W34P/3HQHJ72 %@issn 0065-3438. %2 sid.inpe.br/mtc-m21c/2018/08.06.15.21.39 %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %B Advances in the Astronautical Sciences %@versiontype publisher %P 3937-3950 %4 sid.inpe.br/mtc-m21c/2018/08.06.15.21 %@documentstage not transferred %D 2018 %V 162 %O AAS/AIAA Astrodynamics Specialist Conference, 2017; Stevenson; United States; 20 August 2017 through 24 August 2017 %A Silva, José Batista da, %A Merguizo Sanchez, Diogo, %A Prado, Antonio Fernando Bertachini de Almeida, %@dissemination WEBSCI; PORTALCAPES; MGA; COMPENDEX. %@area ETES %@holdercode {isadg {BR SPINPE} ibi 8JMKD3MGPCW/3DT298S} %3 AAS 17-764.pdf
