Research demonstrates how a series of lunar images could provide key navigational data
TROY, NY (Rensselaer Polytechnic Institute PR) In order for future lunar exploration missions to be successful and land more precisely, engineers must equip spacecraft with technologies that allow them to “see” where they are and travel to where they need to be. Finding specific locations amid the moon’s complicated topography is not a simple task.
In research recently published in the
AIAA Journal of Spacecraft and Rockets, a multidisciplinary team of engineers demonstrated how a series of lunar images can be used to infer the direction that a spacecraft is moving. This technique, sometimes called visual odometry, allows navigation information to be gathered even when a good map isn’t available. The goal is to allow spacecraft to more accurately target and land at a specific location on the moon without requiring a complete map of its surface.
