Sector: Planetary Exploration

Number of satellites: 1

Form factor: 12 U

The ANIME (Asteroid Nodal Intersection Multiple Encounters) mission will explore, from a heliocentric deep space orbit, three "near-Earth asteroids", selected as particularly interesting both from the scientific point of view and from that of planetary defense. The main target was identified in 2000 SG344, which with a diameter of only 40 meters will provide us with unprecedented information on the accretion processes that took place in the early solar system. This asteroid also presents multiple potential solutions of impact with our planet over the next century, and has been considered as a target for future human exploration. Before the rendezvous with 2000 SG344, ANIME's interplanetary trajectory will be optimized to also fly-by two “potentially hazardous asteroids” with peculiar physical properties. All targets will be encountered during their passage through the orbital nodes, thus minimizing the mission's energy budget. Most of ANIME's components have already flown successfully (TRL 9) on several missions in Earth's orbital environment, and the satellite configuration design will include adequate radiation shielding of the most critical components. Overall, the ANIME mission will enable the development of essential technologies for deep space exploration through miniaturized satellites.
