Скачать или смотреть Story of Mars Mission 2020 |Part 1| Perseverance Rover & Ingenuity Drone Launching

° Perseverance was designed with help from Curiosity's engineering team, as both are quite similar and share common hardware. Engineers redesigned Perseverance's wheels to be more robust than Curiosity's, which, after kilometres of driving on the Martian surface, have shown progressed deterioration. Perseverance will have thicker, more durable aluminium wheels, with reduced width and a greater diameter, 52.5 cm (20.7 in), than Curiosity's 50 cm (20 in) wheels. The aluminium wheels are covered with cleats for traction and curved titanium spokes for springy support. The combination of the larger instrument suite, new Sampling and Caching System, and modified wheels makes Perseverance 14 percent heavier than Curiosity, at 1,025 kg and 899 kg, respectively. The rover will include a five-jointed robotic arm measuring 2.1 m (6 ft 11 in) long. The arm will be used in combination with a turret to analyze geologic samples from the Martian surface.

° Ingenuity is a robotic helicopter that will demonstrate the technology for rotorcraft flight in the extremely thin atmosphere of Mars. The aircraft will be deployed from the rover's deck, and is expected to fly up to five times during its 30-day test campaign early in the mission. Each flight will take no more than 90 seconds, at altitudes ranging from 3 to 5 meters (10 to 16 ft) off the ground, but it could potentially cover a maximum distance of about 50 m (160 ft) per flight. It will use autonomous control and communicate with Perseverance directly after each landing. If it works as expected, it will achieve the first powered flight on another planet, and NASA will be able to build on the design for future Mars missions.
