How NASA could play role in rescue bid
As doctors warned of the miners' fragile mental state, Nasa was contacted to help with technology and rations that could help the miners remain healthy. The US space agency was said to be considering the plea.
Experts said such cramped conditions were like those experienced by astronauts on the International Space Station.
Psychiatrists also began detailed assessments using relations and medical files to try to build a profile on the miners.
Relief crews attempting to bore an extraction hole down the shaft of the mine, near the city of Copiapo, 530 miles north of Santiago, delivered glucose gel to help digestive systems, hydration tablets, oxygen and other medications.
The group asked for "food and toothbrushes", as well as beer and peache.
Engineers have been working to reinforce the six-inch wide borehole that broke through to the miners' refuge during an operation hindered by the risk of cave-ins. Using a long hose, they coated the walls with a metallic gel to decrease the risk of more rock falls. (© Daily Telegraph, London)
