Airbus-sponsored Perlan 2 to soar to 100,000 feet in bid to understand climate
The pressurized glider made its first flight in September and is to harness an upward wind that was still unknown 25 years ago.
Designed to fly at 90,000 feet with 2 percent of sea-level air density and temperatures of -70C, the Perlan 2 glider is capable of flight in atmospheric conditions resembling those of Mars.
