(CNN) -- They spent 69 days in the bowels of the earth, 700 meters deep, not knowing if they would survive. For 17 days after the mine in which they were working collapsed, nobody even knew if they were alive. Friday marks the one-year observance of the fateful incident in Chile that trapped 33 miners who were saved in a miraculous rescue that made headlines around the world. 

Fame came after the rescue, which faded quicker in their country than abroad, and since then they have traveled to several destinations all-expenses-paid, though many report having money problems. 

Four of the miners will observe the anniversary of the event that changed their lives in Washington where an exhibit in their honor is being opened at the Smithsonian Institution. 

Mario Sepulveda, one of the miners attending, reflected on the historical significance of the event. 

"In spite of our painful experience, it is very important to us that what is being exhibited will show the world what happened," Sepulveda said. He was the second to be rescued from the mine. 

Since they were rescued last October, the miners have traveled the world. Edison Pena, the miner whose underground workouts in the darkness garnered attention, ran the New York Marathon less than a month after being rescued. 

Pena also appeared on "The Late Show with Dave Letterman" on CBS where he impersonated his idol, Elvis Presley. Then, in January, he was invited as a guest of honor to the Graceland Mansion, in Memphis, Tennessee. Pena had dreamed of visiting the mansion since he became an Elvis fan as a teenager.  QUESTIONS:
