NASA's SkyFall Mars helicopters will feature a revolutionary antenna design
From 2021 to 2024, NASA's Ingenuity helicopter became the first vehicle of its kind to explore the Martian atmosphere and surface. With that proof of concept complete, NASA is preparing to send a trio of helicopters to search for the most precious resource for future astronaut missions: water. Known as the SkyFall trio, these helicopters will detect frozen water within the top few meters of…
NASA's upcoming SkyFall Mars mission will feature a trio of innovative helicopters designed to search for water on the Red Planet. These helicopters, known as SkyFall, will employ ground-penetrating radar with a unique antenna to detect frozen water within the Martian soil. The specially designed antenna, called the Vivaldi antenna, is a flat, curvilinear structure that can cover a wide range of radio frequencies and is lightweight enough to fit beneath the helicopter's legs, allowing for a 15 cm clearance from the Martian surface.
The antenna has been rigorously tested to withstand the harsh conditions of Mars, including repeated landings and extreme temperature fluctuations. Once deployed, the three helicopters will fly over the Martian landscape, projecting radar signals in an ultra-wide frequency range to map shallow subsurface ice deposits crucial for future manned missions.
