Permanent Link to Santa Claus to fly by the International Space Station
Santa Claus will be performing a ceremonial fly-by of the International Space Station (ISS) on Dec. 24. The visit will honor the 20th anniversary of continuous life on the ISS, a milestone achieved in November.
The official NORAD Santa Tracker at NoradSanta.org will allow users to track Santa’s journey all day on Dec. 24. New for this year, visitors will be able to see the ISS orbiting the planet in its precise real-time location by zooming out on the 3D Santa Tracker app. Other updates include additions to Santa’s traditional garb, including a face mask and space helmet.

“The ISS is a spectacular example of what humans can accomplish when we work together,” said Hannah Pinkos, lead developer of the app. “2020 has been a tough year, but I think this special trip is Santa’s way of reminding us to believe in ourselves.”
NORAD, the North American Aerospace Defense Command, is a United States and Canada bi-national organization that defends North America by tracking objects flying in and around its airspace 24 hours a day using radar, satellites and fighter jets. Each year, it joins corporate partners in taking on a special mission to also track Santa’s sleigh. The app shows Santa’s position reflected on a digital twin of the Earth provided by Cesium, a Philadelphia-based geospatial software company.
“Cesium is rooted in aerospace, so it’s especially meaningful to us that our technology will allow millions of people to enjoy this event in real-time from the safety of their homes,” added Cesium CEO Patrick Cozzi.
