ALBUQUERQUE, N.M. (KRQE) – It's been an eventful year for Sandia National Laboratories, celebrating its 75th anniversary. And to cap off the festivities, a ceremony was held Thursday to unveil relics of its past. "Opening the time capsule invites us to reflect on where we've been, where we are today, and where we are headed,” said James Peery, director of Sandia National Laboratories. Before popping off the lid of the 25-year-old time capsule, lab leadership and dignitaries emphasized Sandia's impact on national security, scientific breakthroughs, and local economic growth."The last transformational era that we have had was the coming of Sandia Labs,” said City of Albuquerque Mayor Tim Keller.

Among VHS tapes, floppy disks, and photos of employees from the past, was a letter from then-lab director, Paul Robinson. “Greetings from 1999 as I write this, Sandia is in the midst of its 50th anniversary celebration, honoring its past and acknowledging its achievements,” said Peery on behalf of Robinson, giving insight into what they imagined for the future. “Everyone here wonders and imagines what Sandia will be like in 25 years. We wish you success in your endeavors. We hope that the international science and technology community continues to recognize the stellar contributions made by the National Laboratories,” said Peery read aloud. In scientific fashion, the capsule revealed an array of technology and mementos. From Sandia's Z-machine, molten salt from early solar research, and a melted steel artifact. "Sandia can destroy stuff, right? So, we got proof,” said Sandia Historian Rebecca Ullrich. “As we open the time capsule from our past, we also have the privilege of bearing a new one today, one that will be unearthed by future generations of Sandians,” said Peery. Lab staff added a secret last-minute addition before the burial of the new time capsule. "There are two Taylor Swift friendship bracelets in there and they were offered up by protocol to add to the capsule. It's not on the inventory so we’ll just have to see if the future can figure that out,” said Ullrich. The time capsule items will be on display at the labs for the rest of the year. The new capsule is set to be opened in 2049.
