The optimal trajectories of the mission to the “hazardous” asteroid Apophis, designed to study the asteroid, taking samples of its soil and returning to the Earth, are constructed and analyzed. The scheme of transfer with applying chemical “high”-thrust jet propulsion systems is used. For the transfer to the asteroid in 2019–2022, with the total mission duration being up to two years, the optimal-in-payload-mass, three-impulse trajectories of spacecraft, are obtained. The principal possibility of accomplishing the Earth–Apophis–Earth space mission, based on launch vehicles (LVs) of “Soyuz” type and “Fregat” upper stage, during the transfer in 2019–2022, is demonstrated.
