ANIME in a nutshell: The “Asteroid Nodal positions and velocities. Asteroids 2000 SG344, 2006 Intersection Multiple Encounters” (ANIME) mission HZ51 and 2004 QD14 are selected as ANIME targets concept has been proposed in response to the 2020 due to their pivotal scientific and strategic relevance, Italian Space Agency (ASI) call for ideas for future over a rather large number of suitable alternatives. The CubeSat missions. ANIME aims to explore three near- reference solution (Figure 1) has a total ΔV of 1.05 Earth asteroids (NEAs), selected by virtue of their km/s and a propellant consumption of 1.04 kg (out of peculiar and yet unexplored size and physical regimes, the available 1.5 kg). The ample propellant margin as well as their relevance in terms of planetary guarantees flexibility in terms of: i) departure date protection. Thanks to an optimized trajectory, the changes, ii) strategies for escape from Earth sphere of targets are encountered during their passages through influence (depending on the launch opportunities and their orbital nodes.
