Solar Impulse 2 will take off on the first world tour on an airplane without fuel at 6:30 am (Moscow time) on Monday, March 9
Seventeen thousand solar batteries built into the wings with a span of 72 meters will help the Solar Impulse 2 to travel 35 thousand kilometers in 25 days of flight. Pilots will respond to letters and give interviews in a 3.8 cubic meter cabin, they will have to breathe with the help of an oxygen cylinder, sleep 20 minutes several times a day and withstand temperature changes from -40 to +40 degrees Celsius. In Abu Dhabi, a press conference is held, where you can ask questions to project participants and pilots.
Learn more about the journey, the technical characteristics of Solar Impulse 2 and the pilots' daily routine for the trip - under the cut.
The pilots are already assembled.

Four brushless electric motors are located two on each wing at a distance of 4.95 meters from each other. They develop power up to 70 horsepower - 17.4 power each. The maximum rotational speed is 525 revolutions per minute. The aircraft is equipped with four two-bladed propellers with a diameter of four meters. The maximum speed of the aircraft is 140 kilometers per hour, and the height is 12 kilometers.
In the wings at an angle of 2.2 degrees built-in solar panels in the amount of 17 thousand pieces. They are protected from the weather and ultraviolet using moisture resistant rubber - its layer is only 17 microns. Lithium-polymer batteries with an efficiency of 260 Wh / kg are used as accumulators. The maximum battery capacity is 38 kWh.
"Smart" electronics created from scratch. This is the Mission Control Center - it monitors the telemetric communication system, and the autopilot Stability Augmentation System (SAS), allowing the aircraft to fly for several hours without human intervention.
The volume of the cockpit - 3.8 meters. The cabin is equipped with oxygen cylinders, it will be food and equipment. The pilot, together with his flight suit, must weigh up to 110 kg, food and water must weigh up to 30 kg.
Wingspan - 72 meters, weight - 2.3 tons. Solar Impulse 2 first took to the air in June 2014 .
Video test flight in Abu Dhabi.
The limited capacity makes it necessary to think through the ration as accurately as possible - the total weight of food and water should not exceed 30 kilograms. Nestlé Health Science is responsible for nutrition. Sleep will have to spend 20 minutes several times a day, which requires pilots to have techniques to quickly achieve deep sleep. The temperature will vary from -40 to +40 degrees Celsius.
Every day, pilots, Bertrand Picard and Andre Borschberg, will respond to letters, give interviews to journalists and fly the plane.
The cabin is single, so the co-pilot will get to the place of the next landing not in Solar Impulse 2. Each flight will take from 12 to 120 hours.
The flight plan and landings may vary depending on the political situation. The flight control center will be responsible for the success of the trip. The plane starts from Abu Dhabi, initially departure was scheduled for March 1, but due to weather conditions was postponed to Monday, March 9.
