The concept is to utilize already-gathered surface area information from astronaut photographs and mapping objectives to provide overlapping navigational help. “For safety and science geotagging, its important for explorers to understand exactly where they are as they explore the lunar landscape,” said Alvin Yew, a research study engineer at NASAs Goddard Space Flight Center in Greenbelt, Maryland. “Equipping an onboard device with a regional map would support any objective, whether robotic or human.”
Having a map-based system as a backup would make life a lot much easier for explorers in craters, for example, stated Yew. “The motivation for me was to allow lunar crater exploration, where the entire horizon would be the crater rim.”
When humans begin living and working on the Moon in the Artemis missions, theyre going to require good navigational help. And, therell be LunaNet, the Moons comparable to the Internet. There are locations on the lunar that are quite remote.

Using Moon Mapping Data for Navigational Aid
The heart of Yews system is information from the Lunar Reconnaissance Orbiter. That spacecraft is mapping the Moons surface in the highest possible information and performing other lunar science and expedition jobs. The onboard Lunar Orbiter Laser Altimeter (LOLA) has offered high-resolution topographic maps of the Moon.
Yew fed LOLA information into an AI program that utilizes digital elevation designs to recreate functions on the lunar horizon. It makes them look as they would appear to an explorer on the lunar surface area. The result is a series of digital panoramas. THE AI can correlate them with known surface area objects– such as big boulders or ridges. The goal is to supply accurate location recognition for any given area.
” Conceptually, its like going outdoors and attempting to figure out where you are by surveying the horizon and surrounding landmarks,” Yew stated. “While a ballpark area quote may be easy for a person, we wish to show accuracy on the ground down to less than 30 feet (9 meters). This accuracy unlocks to a broad series of mission concepts for future exploration.”
Yews geolocation system likewise has roots in the abilities of GIANT (Goddard Image Analysis and Navigation Tool), developed by Goddard engineer Andrew Liounis developed it. Scientists utilized GIANT to double-check and confirm navigation information for NASAs OSIRIS-REx objective. That spacecraft went to the asteroid Bennu to gather a sample for analysis here on Earth.
Moon Maps in Your Device
There may soon come a time when a lunar explorer will head out to study different surface area functions. Theyll be geared up with cameras and communication equipment. Thats comparable to Earth geologists heading into the field with a DSLR and a mobile phone with GPS and satellite access. They can discover their method around by noting landmarks, but its constantly useful to have backup approaches. Of course, here on Earth, we have numerous interaction networks.

Still, it will not be long before those lunar geologists are “in the field” themselves. According to a study released by Goddard researcher Erwan Mazarico, a lunar surface area explorer can see at a lot of up to about 180 miles (300 kilometers) from any unblocked area on the Moon. Like a portable GPS unit, a lunar wayfinding gadget would help astronauts in areas that do not have the biggest line-of-site.
Yews geolocation system has some most likely applications beyond the Moon. Even in the world, location technology like Yews will help explorers in terrain where GPS signals are obstructed or based on disturbance. This usage of AI-interpreted visual data against known models of the lunar surface area could supply a new generation of navigation tools not simply for Earth and the Moon, however even on Mars.
