A novel system for slip prevention in unmanned rovers
Wednesday, 15 November 2023 20:19
Given the hostile conditions of extraterrestrial environments, unmanned rovers play a critical role in the exploration of planets and moons. NASA's Mars and lunar exploration rovers have significantly contributed to our understanding of these extraterrestrial bodies. Planetary surfaces often present challenging landscapes with slopes, craters, and dunes.

Rocket exhaust on the moon: NASA supercomputers reveal surface effects
Wednesday, 15 November 2023 19:36
Through Artemis, NASA plans to explore more of the moon than ever before with human and robotic missions on the lunar surface. Because future landers will be larger and equipped with more powerful engines than the Apollo landers, mission risks associated with their operation during landing and liftoff is significantly greater. With the agency's goal to establish a sustained human presence on the moon, mission planners must understand how future landers interact with the lunar surface as they touch down in unexplored moonscapes.
Landing on the moon is tricky. When missions fly crew and payloads to the lunar surface, spacecraft control their descent by firing rocket engines to counteract the moon's gravitational pull. This happens in an extreme environment that's hard to replicate and test on Earth, namely, a combination of low gravity, no atmosphere, and the unique properties of lunar regolith—the layer of fine, loose dust and rock on the moon's surface.
Each time a spacecraft lands or lifts off, its engines blast supersonic plumes of hot gas toward the surface and the intense forces kick up dust and eject rocks or other debris at high speeds.
