Desert flight exams assist tackle navigation challenges revealed by the Ingenuity Mars Helicopter
NASA is utilizing Earth’s harshest desert environments to arrange the following technology of aerial explorers for Mars. Earlier this yr, researchers from NASA’s Jet Propulsion Laboratory (JPL) carried out drone flight exams in Loss of life Valley Nationwide Park and California’s Mojave Desert to refine navigation software program supposed for future rotorcraft missions on the Purple Planet.
Based on a NASA Jet Propulsion Laboratory article, the marketing campaign targeted on growing Prolonged Strong Aerial Autonomy, a software program system designed to assist drones navigate over barren, low-contrast terrain. These situations intently resemble the sand dunes and featureless landscapes that challenged NASA’s Ingenuity Mars Helicopter throughout its later flights on Mars.
Ingenuity, which accomplished its 72nd and last flight in early 2024, relied on visible navigation methods optimized for textured surfaces. Because the helicopter moved over smoother terrain, its capacity to trace movement grew to become harder, contributing to navigation errors.
Testing autonomy in excessive environments
To handle these challenges, the JPL workforce deployed three analysis drones to Mars Hill and the Mesquite Flats Sand Dunes in Loss of life Valley. The areas had been chosen for his or her stark, Mars-like options, together with free sand, minimal floor distinction, and uneven terrain.
The exams had been carried out in late April and early September, with temperatures reaching as much as 113 levels Fahrenheit. Working beneath a uncommon analysis flight authorization, the workforce monitored drone efficiency from laptops arrange beneath short-term canopies.
The marketing campaign produced early insights into how digital camera filters, lighting situations, and new algorithms have an effect on a drone’s capacity to trace floor motion and land safely in cluttered environments. These findings are anticipated to tell the design of future Mars rotorcraft that may function with higher autonomy and resilience.
The work is a part of a broader effort by NASA’s Mars Exploration Program, which funded 25 know-how improvement initiatives this yr geared toward increasing robotic exploration capabilities. Past aerial navigation, this system consists of work on robotic scouts, long-distance gliders, and methods that might help astronaut missions.
An extended historical past of Mars analysis on Earth
NASA’s use of Loss of life Valley as a Mars analog web site dates again to the Seventies, when the company ready for the Viking missions. The area referred to as Mars Hill earned its identify from its volcanic rocks and barren slopes, which resemble Martian geology.
Extra not too long ago, the world has supported testing for the Perseverance rover’s precision touchdown system. The newest drone exams proceed this legacy, utilizing the park as a proving floor for future area applied sciences.
Further exams had been carried out on the Dumont Dunes within the Mojave Desert, a web site beforehand used to guage mobility methods for the Curiosity rover. The rippled sand dunes offered one other variation of feature-poor terrain for evaluating aerial autonomy.
Getting ready for more difficult missions
JPL researchers emphasize that discipline testing stays important for understanding how autonomous methods behave in real-world situations.
As NASA seems forward to future Mars missions, classes realized from Earth-based drone testing might play a essential position in enabling aerial automobiles to discover extra complicated and scientifically beneficial areas of the planet, even when terrain and situations push the boundaries of autonomy.
