The NASA Pathfinder and NASA Pathfinder Plus were the first two aircraft developed as part of an evolutionary series of solar- and fuel-cell-system-powered unmanned aerial vehicles. AeroVironment, Inc. developed the vehicles under NASA's Environmental Research Aircraft and Sensor Technology (ERAST) program.
NASA's Pathfinder prototype. Solar-powered aircraft are electric aircraft that can be an airplane, blimp, or airship and use either a battery or hydrogen to store the energy produced by the solar cells and use that energy at night when the sun isn't shining.
NASA Pathfinder and Pathfinder Plus – This unmanned plane, built by AeroVironment as a part of the NASA Environmental Research Aircraft and Sensor Technology (ERAST) Program, demonstrated that an airplane could stay aloft for extended periods fueled by solar power. After initial successes, the Pathfinder was rebuilt into the larger Pathfinder ...
NASA Pathfinder, Pathfinder Plus and NASA Centurion The Helios Prototype was the fourth and final aircraft developed as part of an evolutionary series of solar - and fuel-cell -system-powered unmanned aerial vehicles .
As Pathfinder was NASA's first Mars surface mission to be solar-powered, the effect of Martian dust settling on solar cells was not well understood before the mission. [3] It was predicted at the time that dust particles in the Martian atmosphere would settle on the solar cells powering Pathfinder , blocking sunlight from striking them and ...
Quarter scale model of Centurion. Centurion, originally built for the 100,000 feet (30,000 m) altitude on solar power milestone specified by the ERAST project, was the third generation aircraft in the NASA Pathfinder series of electrical-powered flying wing unmanned aircraft.
A solar electric vehicle is an electric vehicle powered completely or ... The 1977 Lunokhod programme and the 1997 Mars Pathfinder used solar power to propel remote ...
NASA's Pathfinder Technology Demonstrator (PTD) Project is a series of tech demonstrations of technologies aboard a series of nanosatellites known as CubeSats, providing significant enhancements to the performance of these versatile spacecraft. Each of the five planned PTD missions consist of a 6-unit (6U) CubeSat with expandable solar arrays.
