%0 Journal Article %@nexthigherunit 8JMKD3MGPCW/446AF4B %@resumeid 8JMKD3MGP5W/3C9JGJA %X The main idea of this paper is to propose the construction of an Escape Portal to send a spacecraft to the exterior planets, or even to make it escape from the Solar System, using a Tethered Sling Shot Maneuver (TSSM) with an asteroid. The construction of this portal allows an unlimited number of maneuvers with the same tether, which is very interesting when considering a possible use for small satellites. This structure would be formed by a tether that remains fixed in an asteroid. At the other end of the tether, a large net is fixed, such that the only action required from the spacecraft to make the TSSM is to hit the net. The net can have a mechanism to open a passage to release the spacecraft when the desired rotation is obtained. This technique would avoid some of the problems that appear when assuming that the spacecraft needs to carry a tether on board that would be released to hit the asteroid just before the maneuver. %8 Sept. %N 3 %9 journal article %T Building an “Escape Portal” with tethers fixed in asteroids %@electronicmailaddress antonio.prado@inpe.br %@electronicmailaddress vivianmartinsgomes@gmail.com %@electronicmailaddress chiant69@hotmail.com %@secondarytype PRE PI Local %K Astrodynamics · Orbital maneuvers · Thetered maneuvers · Escape trajectories. %@archivingpolicy denypublisher denyfinaldraft %@usergroup self-uploading-INPE-MCTI-GOV-BR %@usergroup simone %@group DIDMC-CGETE-INPE-MCTIC-GOV-BR %@tertiarymark Trabalho não Vinculado à Tese/Dissertação %@secondarymark B1_ENGENHARIAS_III B5_ASTRONOMIA_/_FÍSICA %@issn 0021-9142 %2 sid.inpe.br/mtc-m21c/2018/11.19.16.07.28 %@affiliation Instituto Nacional de Pesquisas Espaciais (INPE) %@affiliation Universidade Estadual Paulista (UNESP) %@affiliation Universidade Estadual Paulista (UNESP) %B The Journal of the Astronautical Sciences %@versiontype publisher %P 355-375 %4 sid.inpe.br/mtc-m21c/2018/11.19.16.07 %@documentstage not transferred %D 2018 %V 65 %@doi 10.1007/s40295-017-0120-x %A Prado, Antonio Fernando Bertachini de Almeida, %A Gomes, Vivian Martins, %A Chanut, Thierry Gregory Gil, %@dissemination WEBSCI; SCOPUS. %@area ETES %@holdercode {isadg {BR SPINPE} ibi 8JMKD3MGPCW/3DT298S}
