Copiaco, Chile (CNN) -- NASA experts will present options and recommendations Friday evening after assessing the situations and needs of the 33 miners trapped far below the surface of the Earth.
The NASA representatives arrived on site Wednesday. They are helping design the conveyance -- a cage or a capsule to be equipped with oxygen, light and communication abilities -- that will be used to hoist the miners to the surface.
Meanwhile, the miners appear in mind and spirit to be as strong as "solid rock" and are working well together as a team, Chilean Health Minister Jaime Manalich said Thursday.
Each miner has been given a task, he said. For example, the men have been divided into teams of four plus a team leader who are responsible for managing the tubes that carry the supplies that are their lifeblood.
