For adventurers exploring unknown environments, understanding the terrain is very important. Recently, NASA researchers and partners have developed a backpack with a built-in telemetry and mapping system to display real-time 3D terrain maps for explorers, which can be used for lunar exploration.
The “KNACK” backpack is equipped with a “Frequency Modulated Continuous Wave” portable LiDAR scanner. As the user walks, the ground is continuously scanned and detailed information on the surrounding surface is collected in centimeters to create a real-time 3D map with ultra-high resolution.
The technology is not disturbed by ambient light and is suitable for environments such as the moon, but the team still strives to reduce the size of the parts to reduce the burden on astronauts; strengthen sensitive electronic devices to avoid strong solar radiation and the low gravity of the moon.
NASA planetary scientist Michael Zanetti, who leads the “KNaCK” research program, believes that it can be regarded as an enhanced version of the optical measuring device used by surveyors, or an extremely sensitive alarm that helps smart cars avoid collisions. The backpack will help keep astronauts and rovers safe and instantly determine the actual distance to distant landmarks.
Developed by NASA in partnership with Torch Technologies and using Aeva LiDAR technology, it still takes some work to develop a prototype, but testing reps work. The backpack will undergo a major field test in late April at NASA’s Solar System Exploration Virtual Institute (SSERVI) in Kilburn, New Mexico.
