             abstract = "Space missions are an excellent way to increase our knowledge of 
                         asteroids. Near-Earth asteroids (NEAs) are good targets for such 
                         missions, as they periodically approach the orbit of the Earth. 
                         Thus, an increasing number of missions to NEAs are being planned 
                         worldwide. Recently, NEA (153591) 2001 SN263 was chosen as the 
                         target of the ASTER MISSION - the First Brazilian Deep Space 
                         Mission, with launch planned for 2015. NEA (153591) 2001 SN263 was 
                         discovered in 2001. In 2008 February, radio astronomers from 
                         Arecibo-Puerto Rico concluded that (153591) 2001 SN263 is actually 
                         a triple system. The announcement of ASTER MISSION has motivated 
                         the development of the present work, whose goal is to characterize 
                         regions of stability and instability of the triple system (153591) 
                         2001 SN263. Understanding and characterizing the stability of such 
                         a system is an important component in the design of the mission 
                         aiming to explore it. The method adopted consisted of dividing the 
                         region around the system into four distinct regions (three of them 
                         internal to the system and one external). We performed numerical 
                         integrations of systems composed of seven bodies, namely the Sun, 
                         Earth, Mars, Jupiter and the three components of the asteroid 
                         system (Alpha, the most massive body; Beta the second most massive 
                         body; and Gamma, the least massive body), and of thousands of 
                         particles randomly distributed within the demarcated regions, for 
                         the planar and inclined prograde cases. The results are displayed 
                         as diagrams of semi-major axis versus eccentricity that show the 
                         percentage of particles that survive for each set of initial 
                         conditions. The regions where 100per cent of the particles survive 
                         are defined as stable regions. We found that the stable regions 
                         are in the neighbourhood of Alpha and Beta, and in the external 
                         region. Resonant motion of the particles with Beta and Gamma was 
                         identified in the internal regions, leading to instability. For 
                         particles with I > 45° in the internal region, where I is the 
                         inclination with respect to Alpha's equator, there is no stable 
                         region, except for particles placed very close to Alpha. The 
                         stability in the external region is not affected by the variation 
                         of inclination. We also present a discussion of the long-term 
                         stability in the internal region, for the planar and circular 
                         case, with comparisons with the short-term stability.",
