Los Alamos trackers will use state-of-the-art technology to mark the course taken by St. Nick and his eight tiny and highly efficient reindeer.
"We expect Santa and his team to arrive in northern New Mexico about midnight on Christmas Eve," said scientist Diane Roussel-Dupré of the Lab’s Space Data Systems group.
Los Alamos supports Santa trackers at North American Aerospace Defense Command (NORAD), which has been following Santa’s Christmas runs since the 1950s.
