Flight Testing NASA's Prandtl-D Research Aircraft

NASA: Image of the Day -

NASA's Armstrong Flight Research Center engineers are working on an increasingly complex aircraft called the Preliminary Research Aerodynamic Design to Lower Drag, or Prandtl-D. The aircraft features a new method for determining the shape of the wing with a twist that could lead to an 11-percent reduction in fuel consumption.

Robotic Eyes to Assist Satellite Repairs in Orbit

NASA is developing and demonstrating technologies to service and repair satellites in distant orbits. This photo looks closely at one of the tools that could be used for satellite servicing in the future: the Visual Inspection Poseable Invertebrate Robot (VIPIR), a robotic, articulating borescope equipped with a second motorized, zoom-lens camera.

Damaging heavy rains fell on South Carolina in the southeastern United States at the beginning of October 2015. Much of that water had, by mid-October, flowed into the Atlantic Ocean bringing with it heavy loads of sediment, nutrients, and dissolved organic material. The above VIIRS image shows the runoff as it interacts with ocean currents.
