NASA works with the North American Aerospace Defense Command to track Santa Claus every December 24th. NASA provides satellite data to help NORAD pinpoint the location of Santa’s sleigh as it travels around the world.
NASA’s Goddard Space Flight Center uses satellite data to provide precise weather updates to NORAD as it begins tracking Santa’s progress after sundown every Christmas Eve. One NASA satellite traces the infrared signal from the red nose of lead reindeer Rudolph.
From its base at the Peterson Air Force base in Colorado, NORAD posts real-time updates of Santa’s progress on its website, NoradSanta.org. Updates are provided in eight languages. NORAD also updates Santa's journey on social media such as Facebook, Twitter and YouTube.
