Abstract: A two-wheeled vehicle tire achieves a further improvement particularly in the traction performance during turning on soft ground. A two-wheeled vehicle tire includes a tread portion formed in an annular shape. The tread portion includes: center land portions arranged on a tire equator CL; middle land portions arranged on the tire width-direction outer side of the center land portions; and shoulder land portions arranged on the tire width-direction outer side of the middle land portions, and T-shaped or Y-shaped land portions each constituted by three partial land portions connected at one end are arranged between the center land portions and the shoulder land portions.

Abstract: In a rendezvous maneuver for approaching a rendezvous spacecraft to a target spacecraft through a reference trajectory for approach which is different in altitude and period from a trajectory of the target spacecraft, when the rendezvous spacecraft is deviated from the reference trajectory for approach as a result from a failure in the maneuver, it is first maneuvered in the direction of altitude after 0.2 revolutions of the rendezvous spacecraft, and then maneuvered in the direction of phase after another 0.2 revolutions. The rendezvous spacecraft is thereby restored to the reference trajectory with no fear of entering a collision course, so that high reliable retry/recovery may be performed promptly and safely.
