Newsflash

"Unique atmospheric circulation over Antarctica during its summer months allows scientists to launch balloons from a site near McMurdo Station, the Foundation's logistics hub in Antarctica, and recover them from nearly the same spot weeks later. During that time, each balloon circles the continent one to three times. Scientists from the United States, Japan, South Korea, France and other countries are using the balloons to investigate the nature of ultra-high-energy cosmic rays and to search for antimatter."
