During crewed lunar landings, astronauts are expected to guide a stable and controlled descent to a landing zone that is level and free of hazards by either making landing point (LP) redesignations or taking direct manual control. However, vestibular and visual sensorimotor limitations unique to lunar landing may interfere with landing performance and safety. Vehicle motion profiles of candidate lunar descent trajectories were used as inputs to a mathematical model for orientation system function, to predict human perception of orientation and identify disorientating illusions. Simulations were conducted using the vestibular-only portion of the model as well as incorporating the activation of visual cues. Dust blowback from the descent engine was modeled as well. The NASA Ames Vertical Motion Simulator was used to experimentally investigate human orientation perception during manually controlled landing trajectories. Subjects were tasked with reporting perceptions of vehicle tilt angle and horizontal velocity. There were three treatment conditions studied: eyes closed (blindfolded), eyes out the window on simulated lunar terrain, or eyes on display instruments. It was seen in the vestibular-only orientation perception model that the acceleration profile of the descent engine throughout candidate trajectories is likely to create a somatogravic illusion. This illusion creates the perception of being upright even when the actual vehicle orientation is significantly tilted. The model predicts the underestimation of tilt angle for the candidate automated trajectories as well during maneuvers resulting from LP redesignation and manual control maneuvers. The activation of visual pathways in the model improved orientation perceptions, however misperceptions persisted when visual cues were limited such as prior to the pitch-over maneuver and during dust blowback. Results from the motion base simulator experiment are in agreement with the likelihood of the somatogravic illusion occurring without the astronauts' continued focus on instrument displays. Horizontal velocity was poorly perceived without reliable visual cues, both in magnitude and direction. Misperception of spatial orientation is likely to increase workload and may reduce performance and safety during landing. Countermeasures should be designed to minimize the risk of astronaut disorientation, including the design of advanced displays.

Landing is a dangerous and complex phase of any flight. Landing on an airless, dusty world presents unique challenges to perception, including dust blowback. During crewed lunar landings, astronauts will either be directly piloting the lander or supervising the automation in the event they need to take over piloting duties. An accurate perception of vehicle attitude is critical if the astronaut is to bring the craft down safely. We aim to study human perception of orientation under different visual cues using a helicopter simulator. We conducted a simulator-only lunar landing experiment with seventeen helicopter pilot subjects at USAARL utilizing the 6 degree-of-freedom moving-base UH-60 helicopter simulator. The subjects did not fly the simulator but continuously indicated his/her perceived pitch and roll angles throughout each trial by keeping a modified joystick aligned with Earth vertical, and the accuracy of the responses has been analyzed to determine the effect of visual cue on attitude perception. The subjects experienced recorded trajectories under five different visual conditions: no visual cues, out-the-window cues with no, medium, and high dust, and instrument cues. Regression models were fit to the correlations between the Subjects' indicated perceived pitch and roll angles and the simulator model pitch and roll angles. It was found that the no vision cue severely hindered the subjects' ability to accurately perceive craft attitude, while the instrument cue enhanced it. The effect of the different levels of dust, as compared to out-the-window no dust condition and the instrument conditions were not statistically significant, though they were better than no vision.
