 The MANTIS mission would perform a flyby tour of near-Earth and Main belt asteroids as a means of observing several members of this population of objects, providing discovery science and also returning data that would be complementary and contextual to past, present, and future missions.The spacecraft would visit 14 asteroids, and would focus on members of eight known collisional families of different spectral classes and in different parts of the asteroid belt.The largest of these is 50 Virginia, an 85-km asteroid.
