The primary objective of a star tracker would be to capture images of the surrounding star field for the spacecraft to perform an internal calculation of its orientation in space. This task is completed a fair number of times each minute, and the accuracy of individual instruments measurements on LADEE depends on the star tracker making a precise and calculated orientation of the spacecraft.
The LADEE star tracker will not use any ordinary camera, but rather, has a wide-angle field of view so that it can capture the night sky within a single frame. So far, there has been no images of extra terrestrial life captured by LADEE, and neither did we see Soundwave from Michael Bay’s Transformers movie franchise make a cameo appearance. We hope that you like the refreshing pictures of the lunar landscape in the photo gallery below. [Press Release]
