“Fly with Aerocene Pacha,” Tomás Saraceno for Aerocene,
Artist Tomás Saraceno launched a solar air balloon above the Salinas Grandes salt flat in Jujuy, Argentina, achieving the world’s first manned sun-powered free flight.
The balloon, which absorbs ultraviolet rays to raise its temperature and ascend into the atmosphere, can lift up to 250 kg (~551 lb) and transport two human passengers.
