Beijing has recently successfully completed a test flight of its largest high-altitude airship.

China has reportedly conducted a 48 hour test flight of its largest high-altitude airship, the Yuanmeng (Dream) in near space–the atmosphere between 20 kilometers to 100 kilometers altitude–IHS Jane’s Defense Weekly reports.

The Yuanmeng, according to a Chinese media outlet, ascended to an altitude of 20 kilometers at a test area near Xilinhot in Inner Mongolia using solar power to power its three propeller engines.

Beijing’s new high-altitude aircraft is one of the largest solar-powered airships in existence to date. According to Popular Science, the Yuanmeng has a volume of 18,000 cubic meters, a length of 75 meters and a height of 22 meters. It can carry a payload of 5 to 7 tons including “broadband communications, data relay, high-definition observation, space situational awareness, and airborne imaging systems” all powered by the sun.

A Chinese scientist involved with the project told Want China Times that the airship has been made of an extremely lightweight material capable of enduring tremendous pressure and that it is equipped with a highly efficient solar battery and lightweight avionics. “The biggest challenge for the near-space airship is the big temperature difference in the day and night,” another scientist told The People’s Daily Online.
