August 22, 2010 - The miners send a note up tied to a probe which was lowered by authorities earlier in the day. Written in red ink, it reads, "We are fine in the shelter, the 33 of us."
August 23, 2010 - A second probe reaches the miners. Rescuers are now capable of relaying communications and can send food and water to miners. Before this, the miners survive by sharing small amounts of tuna and mackerel that were in the shelter, along with water.
