NASA’s car-size Mars rovers are awesome, versatile machines capable of traversing rugged terrain. But they’re not made to descend down the sides of craters. For that, NASA would need something like its DuAxel prototype rover, a wild concept that is two rovers in one.
When all together, DuAxel is a four-wheeled rover. The rear can anchor itself to the ground while the front goes free on two wheels. A tether holds the pieces together while the front section rappels down a steep slope. This could work well for exploring currently inaccessible crater walls on Mars.

NASA put a DuAxel prototype through its paces in the Mojave Desert in California. “DuAxel performed extremely well in the field, successfully demonstrating its
Driver fatigue brought on by the monotonous drone of road roar and wind noise could soon be a thing of the past, as Jaguar Land Rover reveals new noise-cancelling technology.
Similar to how headphones with ANC (active noise cancelling) work, the new system uses sensors on each wheel to monitor vibrations. These are then used to produce a sound wave through the car’s audio system that cancels out the unwanted noise, particularly low-frequency sounds up to 300Hz.
The system debuts on the new Jaguar F-Pace, new Jaguar XE, and Range Rover Velar, but is likely to soon roll-out across the rest of the JLR range.
JLR explains how the system “calculates the opposite phase sound wave needed to remove the noise heard by the
After touching down on the Red Planet Feb. 18, 2021, NASA’s Mars 2020 Perseverance rover will scour Jezero Crater to help us understand its geologic history and search for signs of past microbial life. But the six-wheeled robot won’t be looking just at the surface of Mars: The rover will peer deep below it with a ground-penetrating radar called RIMFAX.
2020 Land Rover Defender 110 first drive review: Off-rad chops meets modern tech
“The 2020 Land Rover Defender combines old-school ruggedness with modern refinement.”
Impressive off-road capability
Drives like a car, not an SUV
Modern Land Rover is defined by SUVs that combine luxury with off-road capability, vehicles that, despite their mud-plugging abilities, are typically compared to the likes of Mercedes-Benz. It wasn’t always this way.
When Land Rover launched in 1948, it made simple, rugged vehicles aimed more at farmers, explorers, and soldiers than wealthy suburbanites. Those early Land Rovers were Britain’s answer to Jeep, not Mercedes. As Land Rover drifted further into luxury, the Defender became the last reminder of the brand’s origins. Until it went out of production in 2016, that is (United States sales ceased in 1997).
Fans loved the original Defender because it existed in a time
