a Conceptual diagram showing field of views for the simultaneous observation of a landing site candidate from QSO-LA by TENGOO, OROCHI, and MIRS (field of views are not in precise scale). The area of about 1 km × 1 km will be observed continuously by TENGOO and MIRS, and imaged once by OROCHI, and the north–south areas not covered by TENGOO will be imaged in another rotations. b The maximum and the minimum ground speed of Phobos surface relative to the spacecraft at various QSOs. The maximum speed is achieved when the spacecraft is at sub-Mars and anti-Mars position, while the minimum speed is at leading and trailing position
