Soviet Lunokhod Control Crew Experiences MoonrcSleas: According to one of the commanders, crew control ofs difficult due to orientation problems. These problems arise because there is nothing on the moon to "fix" the eye on. For example, one big stone "as estimatedistance ofrom the vehicle. The crew was asked to steer the vehicle toward the stone. The vehicle tried to approach it but the stone could not be seen because it had, in reality, been lying next to the Lunokhod. On the TV screen the stone appeared large and_not located close to the vehicle.
Comment: This indicates that Soviet earth crew members have moon orientation problems somewhat similar to thoseby US astronauts walking on the moon. If thisorientation problem is not corrected the overallof theould be severely limited, particularly if the vehicle encounters exceptionally hazardous terrain.of visual spatial discrimination is th? objective of Soviet human factors research. It is likely that thewill draw upon this research in order to improve the spatial discrimination of the Lunokhod earth crewhis training should aid the crew members in more correctly estimating distances and sizes on the moon surface therebyigh reliability of this unique man-machine system.Original document.
