Planned second manned Dynasoar single-orbit flight. Project cancelled in December 1963

Objectives of the second manned Dynasoar single-orbit flight were to demonstrate maneuver in orbit and during re-entry, and systems evaluation. Orbital attitude maneuvers would have been made to plus/minus 90 degrees in all axes, including visual reference checks. During re-entry control maneuvers would be made at pitch angles of from 10 to 50 degrees with a 3000 m altitude margin.
