NASA delays Mars copter flight for tech check

NASA has delayed by at least several days the first flight of its mini-helicopter on Mars after a possible tech issue emerged while testing its rotors, the US space agency said Saturday.

NASA space copter ready for first Mars flight

The helicopter that NASA has placed on Mars could make its first flight over the Red Planet within two days after a successful initial test of its rotors, the US space agency said Friday.

The smallest motor in the world

A research team from Empa and EPFL has developed a molecular motor which consists of only 16 atoms and rotates reliably in one direction. It could allow energy harvesting at the atomic level. The special feature of the motor ...

Intelligently recovering and recycling balsa wood

There are 30,000 wind turbines in operation in Germany, many of which are starting to age. In 2019, 2000 rotor blades had to be discarded; in 2024, this figure will shoot up to 15,000. But where to put these up to 90-meter-long, ...

Ion wind technology breakthrough takes flight

A new spin on propulsion is taking flight in a SUNY Oswego lab, leading to electrical and computer engineering faculty member Adrian Ieta and the SUNY Research Foundation pursuing a patent on this promising technology.

To improve drones, researchers study flying insects

The unmanned aircraft known as drones, used by hobbyists, researchers and industry to take aerial images and perform other tasks, are growing ever more popular—and smaller. But that miniaturization, which has produced drones ...

Improved control of big power in little motors

Little motors power everything from small comforts, such as desk fans, to larger safety systems, like oven exhaust systems—but they could be more precise, according to a research team from Mitsubishi Electric Research Laboratories.
