NASA's Mars helicopter testing enters final phase

NASA's Mars Helicopter flight demonstration project has passed a number of key tests with flying colors. In 2021, the small, autonomous helicopter will be the first vehicle in history to attempt to establish the viability ...

NASA's Mars helicopter completes flight tests

Since the Wright brothers first took to the skies of Kill Devil Hill, North Carolina, Dec. 17, 1903, first flights have been important milestones in the life of any vehicle designed for air travel. After all, it's one thing ...

Maths for midges that pull 10g

Midges move with ferocious randomness, frequently subjecting themselves to accelerations of more than 10g, well beyond the limit of fighter pilots, as they duck and dive in swarms that still retain an almost paradoxical cohesiveness ...

Tricky take-off kept pterodactyls grounded

A new study, which teamed cutting-edge engineering techniques with paleontology, has found that take-off capacity may have determined body size limits in extinct flying reptiles. The research simulated pterodactyl flight ...

How do honeybees control their flight speed to avoid obstacles?

Unlike humans, bees have a dorsal visual field that enables them to avoid obstacles above their heads. Until now, it was not known whether this helped them to control their flight speed. Recent research by French biorobotics ...
