Recall that now on Mars is the aircraft Ingenuity, which arrived aboard the Perseverance rover. This helicopter is equipped with a single rotor with a pair of blades approximately 1.2 m in diameter. The Ingenuity weighs approximately 1.8 kg. It should be noted that the helicopter is not intended for scientific research: it is designed solely to demonstrate the possibility of flight in the Martian atmosphere.
The next-generation aircraft is now referred to as the Mars Science Helicopter. In accordance with the preliminary concept, this machine will be much larger and heavier than the Ingenuity.
In particular, the weight of the new helicopter can be about 30 kg. The machine will be able to carry onboard up to 5 kg of various scientific equipment. The design assumes the presence of six rotors, and the flight range within one mission will reach 10 km.
So far, however, it is not clear in what time framework on the creation of the Mars Science Helicopter can be completed. In addition, NASA specialists have yet to determine the scientific goals for the machine. It is expected, in particular, that the helicopter will be able to explore areas that the rovers cannot reach.
