Correct Answer: A
Explanation:
NASA scientists are developing a technology to help drones land safely during emergencies. The announcement regarding the new technology was made by NASA on 25 May 2017. After eight test flights, the technology has successfully spotted safer landing zones like swamps or drainage ditches to crash instead of on top of people’s cars.
This crash-landing software for drones was developed by Patricia Glaab, an aerospace technologist at NASA Langley Research Centre, and her fellow NASA colleague Lou Glaab.
The software links on-board drone components like batteries and motors to monitor their health.
The technology help them identify when something on the drone goes wrong, and puts the aerial vehicles in a crash-landing mode.
When triggered, the software checks a pre-installed database of nearby safe zones and identifies one for safe landing. The software also incorporates technology that lets drones recognise and avoid objects on the ground using on-board cameras.
