Flight tests have resumed on subscale aircraft that could one day observe the Martian atmosphere and a variant that will improve collection of Earth’s weather data.
Work on the shape of the aircraft and the systems it will need to fly autonomously and collect data are ongoing for the Preliminary Research Aerodynamic Design to Land on Mars, or Prandtl-M aircraft. Student interns with support from staff members at NASA Armstrong Flight Research Center in California are advancing the project.
The March flights included two slightly different Prandtl-M aerodynamic models that were air launched from a remotely piloted Carbon Cub. The research validated the airframe that will be the basis for a potential Mars aircraft and the Weather Hazard Alert and Awareness Technology Radiation Radiosonde (WHAATRR) Glider on Earth.
