MILTON KEYNES, U.Okay. — The European aerospace big 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 expertise, which is 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 House Company (ESA), that are conducting the Mars sample-return marketing campaign collectively, abandoned 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 the whole European space business this yr after the launch of the ExoMars Rosalind Franklin rover, which was scheduled to happen in September, was called off because of Russia’s involvement with the challenge.

The fetch rover, which may drive as much as twice as quick as Perseverance, in response to Airbus officers, encompasses a distinctive wheel design impressed by the Apollo-era moon rovers. The wheels are encased in protecting tires product of metallic mesh that conforms to the floor and permits the rover to climb over obstacles extra effectively.
Through the latest checks within the quarry close to Milton Keynes, a city about 50 miles (80 kilometers) northwest of London, Airbus engineers put by 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 proud of the way it’s been performing on this pretend Mars [environment],” Warren Hamilton, a steerage, navigation and management methods architect on the Pattern Fetch Rover challenge at Airbus, instructed House.com. “We have made it as Mars-like as attainable, scattering rocks all through and ensuring that the atmosphere is stuffed with attention-grabbing obstacles.”
The largest problem in making the expertise work, Hamilton mentioned, is the necessity to use hardened space-qualified computer systems, which lag behind the present cutting-edge. As an alternative of driving round like an autonomous automobile, the rover stops to guage the terrain each couple of meters earlier than executing the subsequent a part of its journey.
“The space-rated computer systems are very sluggish, form of Nineteen Nineties expertise,” Hamilton mentioned.
Hamilton admitted that the group was greatly surprised by the choice to interchange the fetch rover with two helicopters however hopes the expertise will get one other probability in one of many upcoming moon exploration missions as a part of NASA’s Artemis program.
“The expertise that we have developed and are nonetheless growing for the navigation system for impediment avoidance and autonomous traverse is relevant to any atmosphere 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 may change to the moon with out too many difficulties, the rover design itself would require a major technical overhaul.
“The temperature extremes are extra excessive on the moon,” Dobke instructed House.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, built to search for traces of life beneath the Pink Planet’s floor utilizing a 6.6-foot-long (2 meters) drill, was presupposed 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 determination on the challenge will likely be made later this yr. To proceed with ExoMars would require a major funding from the European House Company and its member states on high 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.
