Although it hasn't been officially confirmed, last week's reported collision between a drone and a Piper PA-23 was, in fact, a bird strike. Residue on the aircraft's de-icing boot was analyzed by the Smithsonian Institution and found to contain the remains of a small, non-predatory bird, sources familiar with the investigation told Avweb on Friday. The NTSB has opened up an investigation on the incident but we weren't given a specific schedule on when its findings might be released.
Bioinorganic Chemistry: Engineered protein, metal ion, and linker form new type of hybrid material
Hopping, tumbling and flipping over are not typical maneuvers you would expect from a spacecraft exploring other worlds. Traditional Mars rovers, for example, roll around on wheels, and they can't operate upside-down. But on a small body, such as an asteroid or a comet, the low-gravity conditions and rough surfaces make traditional driving all the more hazardous. Enter Hedgehog: a new concept for a robot that is specifically designed to overcome the challenges of traversing small bodies.
