Officials said it would take about an hour for each miner to be rescued -- 25 minutes for the steel capsule to reach the miner and 15 minutes for the miner to ascend.
Rescue workers were giving themselves 48 hours to complete the mission of returning the men to their families.
Beforehand, the miners were readying themselves for the rescue. They were taking aspirin to reduce chances of clots when cramped in the capsule and they began a liquid diet to ease nausea.
Sources at the rescue site told ABC News that the men spent their final day underground signing souvenir Chilean flags for their rescue workers. They collected rocks and other mementoes to bring up with them at what has come to be called Camp Hope.
The men also are struggling with what will happen in their first few moments out of the mine and in the Chilean air. Officials want the men to be helicoptered to a hospital shortly after they surface, but the men have said they want to stay at the site as a group until everyone is succesfully lifted out of the mine.
The steel capsule designed to rescue the men was tested on Monday.
In its first test run down the drill shaft, the rescue capsule carrying sandbags worked exactly as intended. Officials stopped it just short of the chamber where the men have been trapped.
"The last 10 meters are not important. ... We couldn't risk that someone will jump in," Golborne said jokingly.
The rescue capsule leaves nothing to chance. A man riding inside was to wear an oxygen mask, his heartbeat and body temperature was to be monitored, and he was to wear a telephone headset to talk with the rescue team above.
Every second of the miners' ascent was to be monitored by video camera.
"This will alert us above ground if there is a problem," a rescue team member said.
If something goes wrong during a journey to the surface, there is an escape system that allows the miner to separate the capsule so that he can be lowered back into the mine.
When the men reach the surface, they were to wear sunglasses to protect their eyesight from the glare of daylight.
Officials also displayed the special clothing the men will wear for the ascent -- shirts with their names embroidered, as well as girdles and socks.
The miners' families were counting the final hours.
Liliana Ramirez, the wife of Mario Gomez, the oldest miner, said that she was anxious, but happy, too, that "that this nightmare is coming to an end."
The men, excited to see their loved ones, wanted to look their best. They asked for shampoo and shoe polish.
The tent city outside the mine gates was a carnival-like atmosphere as families and the massive international press corps counted down the hours until the miners' escape.
With so much of the world following every twist and turn in this complex rescue, the Chilean government was broadcasting a seven-camera live satellite feed of the rescue for all to see.
But Maria Jose Gomez just wanted to see her father the 63-year-old Mario Gomez.
When asked what her words would be to her father, Maria said in Spanish: "I believe at that moment there will be no words ... only hugs."
