A Chinese research team has developed an air-ground dual-purpose unmanned aerial vehicle (UAV) weighing only 300 grams, equivalent to the weight of an apple, showing promising potential in future Mars exploration.

The UAV can take off at any time, traverse obstacles, and boasts superb endurance, according to the research team from the School of Astronautics of Harbin Institute of Technology. It is of vital significance for scientific exploration of Mars, the team added.
