NASA and General Electric Co. announced they had accom-plished precision tracking of EXPLORER XXII with a laser device. Tests were conducted at NASA Goddard Space Flight Center using a ruby laser mounted on a telescope. With the telescope aimed along the predicted path, the laser was flashed several times as EXPLORER XXH, containing an array of corner reflectors, passed overhead. The reflectors, made of quartz crystal, were designed to return the beam of the laser almost exactly where it came from. The optical signals were displayed on an oscilloscope. As the laser pulse traveled from the telescope to the satel-lite, then back to the ground, the elapsed time measured could be con-verted into distance. Expected accuracy Was Within 10 ft. (Chic.
