MILTON KEYNES, U.Ok. — The European aerospace large Airbus has been testing its Mars Pattern Fetch rover over the previous few weeks in simulated Martian terrain in a quarry close to London, hoping the technology, which is now not ticketed for Mars, will get a second probability on a future moon mission.
The rover was initially anticipated to gather samples cached by NASA’s Perseverance Mars rover for a return to Earth within the early 2030s. However NASA and the European Area Company (ESA), that are conducting the Mars sample-return marketing campaign collectively, deserted the fetch rover idea in July this yr in favor of a pair of small NASA helicopters.
The cancellation was a second Mars rover-related setback for Airbus and your entire European area business this yr after the launch of the ExoMars Rosalind Franklin rover, which was scheduled to happen in September, was known as off due to Russia’s involvement with the challenge.

The fetch rover, which might drive as much as twice as quick as Perseverance, in line with Airbus officers, incorporates a distinctive wheel design impressed by the Apollo-era moon rovers. The wheels are encased in protecting tires made from metallic mesh that conforms to the floor and permits the rover to climb over obstacles extra effectively.
In the course of the latest exams within the quarry close to Milton Keynes, a city about 50 miles (80 kilometers) northwest of London, Airbus engineers put via its paces the autonomous navigation system that permits the rover to independently plan its route and safely keep away from obstacles.
“We have been extraordinarily pleased with the way it’s been performing on this pretend Mars [environment],” Warren Hamilton, a steerage, navigation and management techniques architect on the Pattern Fetch Rover challenge at Airbus, informed Area.com. “We have made it as Mars-like as potential, scattering rocks all through and ensuring that the setting is stuffed with attention-grabbing obstacles.”
The largest problem in making the technology work, Hamilton mentioned, is the necessity to use hardened space-qualified computer systems, which lag behind the present cutting-edge. As a substitute of driving round like an autonomous automobile, the rover stops to judge the terrain each couple of meters earlier than executing the following a part of its journey.
“The space-rated computer systems are very sluggish, kind of Nineteen Nineties technology,” Hamilton mentioned.
Hamilton admitted that the workforce was greatly surprised by the choice to exchange the fetch rover with two helicopters however hopes the technology will get one other probability in one of many upcoming moon exploration missions as a part of NASA’s Artemis program.
“The technology that we have developed and are nonetheless creating for the navigation system for impediment avoidance and autonomous traverse is relevant to any setting actually,” Hamilton mentioned. “We have taken it right into a quarry, and it is labored completely right here.”
Hamilton’s colleague Ben Dobke, an built-in breadboard supervisor on the Mars Fetch Rover challenge at Airbus, mentioned that whereas the navigation system might change to the moon with out too many difficulties, the rover design itself would require a big technical overhaul.
“The temperature extremes are extra excessive on the moon,” Dobke informed Area.com. “Mars has a typical day like Earth, about 24 hours, however the moon has 14 days of shadow. Constructing a system that may function on the moon can due to this fact be difficult. That is one thing we’re going to look into in future research.”
Within the meantime, ESA, which funded the event of the Mars Pattern Fetch rover, is working to map out the way forward for the ExoMars Rosalind Franklin rover. The ExoMars rover, constructed to seek for traces of life beneath the Purple Planet’s floor utilizing a 6.6-foot-long (2 meters) drill, was purported to launch from the Russia-run Baikonur Cosmodrome in Kazakhstan final month. The launch was scrapped after ESA first suspended after which stopped cooperation with Russia in response to the invasion of Ukraine.
ESA hopes to get the ExoMars rover to Mars towards the top of this decade with the assistance of NASA. A remaining choice on the challenge can be made later this yr. To proceed with ExoMars would require a big funding from the European Area Company and its member states on prime of the 1.3 billion euros already spent on this system. Along with offering the launch automobile, Russia funded and constructed the rover’s touchdown platform, which must be remade from scratch.
