Chile will ask advice from NASA to attend the trapped miners, Momento 24

"Chilean Health Ministry will ask the NASA for advice to the implementation of efficient techniques in pursuit of maintaining the health condition of the 33 miners trapped in San Jose mine, 700 meters deep, in Atacama desert, and who, according to estimates, will not be rescued until 3 months. The initiative of the trans-Andean country's health portfolio refers that at this moment, the miners' living conditions are similar to those experienced by astronauts in a space station. It is known that they eat food specially designed for this purpose."

Chile miners to get coping advice from NASA, Christian Science Monitor

"With 33 miners trapped deep underground, Chile is seeking advice from NASA on how to keep them mentally and physically fit for the months it may take to rescue them. "We received a request from the Chilean government about advice related to our life science research," John Yembrick, a NASA spokesman, told Wednesday."

"Astronaut Jerry Linenger and architect Eduardo Strauch know the remarkable quality that keeps the trapped Chilean miners going: the immense power of hope. Linenger and Strauch are living proof of survival amid isolation. They say that power is in us all."

Life and Physical Sciences Research for a New Era of Space Exploration: An Interim Report, NRC

"In response to requests from Congress, NASA asked the National Research Council to undertake a decadal survey of life and physical sciences in microgravity. Developed in consultation with members of the life and physical sciences communities, the guiding principle for the study is to set an agenda for research for the next decade that will allow the use of the space environment to solve complex problems in life and physical sciences so as to deliver both new knowledge and practical benefits for humankind as we become a spacefaring people."

Our economy needs a robust space program, editorial, Houston Chronicle

"It would be prudent to keep the space shuttles flying with new missions to maintain a vital back-up contingency, until replacement spacecraft and commercial space transportation achieve reliable operations. The space shuttle's unique capability to launch heavy payloads into space, or return hardware from orbit, is the only means available of flying critical replacement components to support the $100 billion International Space Station. If the 300-ton space station is ever taken out of service, the space shuttle is the only vehicle in existence that could safely deorbit the massive structure."

Keith's note: Hmm ... "deorbit" implies that you are going to drop the ISS into the ocean. Mir, which was somewhat comparable in size - with things pointing out in all directions. Mir was deorbited with several Progress flights. Why couldn't a series of Progress, HTV, ATV missions do the same for the ISS? Or are you going to use Shuttle propulsion to deorbit the ISS? Or are you talking about taking the ISS apart and returning the pieces to Earth in a shuttle cargo bay? Given how many flights it took to assemble the ISS, that would be a rather time consuming and expensive undertaking. And then what about the Russian segment? That would have to come back too - just like Mir did.

NASA ISS On-Orbit Status 16 August 2010

"Stage EVA-17 by FE-4 Doug Wheelock & FE-2 Tracy Caldwell-Dyson was completed successfully in 7hr 20min, fully accomplishing its objective of installing the spare ETCS (External Thermal Control System) Loop A PM (Pump Module) plus additional tasks. The PM has been checked out and is functioning nominally. Loop A will be fully in service later this week. This was the third contingency spacewalk to replace the Loop A ammonia pump."

Today's EVA

Wednesday Space Station EVA

"Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson spent Tuesday completing preparations for their second spacewalk Wednesday out of the Quest airlock to replace the failed ammonia coolant Pump Module on the S1 truss of the complex while the International Space Station Mission Management Team gave its final approval to proceed with the spacewalk."

EVA Plans Hit A Snag

Space Station EVA Unable To Remove Failed Ammonia Pump - More EVAs Ahead

"The next spacewalk to complete the removal of a failed ammonia pump module and installation and activation of a new pump module on the International Space Station's S1 Truss will take place no earlier than Wednesday. Expedition 24 Flight Engineers Doug Wheelock and Tracy Caldwell Dyson completed the first spacewalk to remove and replace the pump module at 3:22 p.m. EDT Saturday. As the result of an ammonia leak in the final line that needed to be disconnected from the failed pump module, the day's tasks were only partially completed."

NASA Moves Space Station Repair Spacewalk To Saturday

"The first of two spacewalks by NASA astronauts to replace a failed ammonia pump on the International Space Station has been moved to Saturday, Aug. 7. A second spacewalk is planned for Wednesday, Aug. 11, to complete the repairs. Teams of flight controllers, engineers, and spacewalk experts have made significant progress in preparing for the first spacewalk, but need an additional day to get ready. The additional time allows for final procedures to be sent late Thursday to the station, giving the crew a full day to review the plans developed by Mission Control. Managers also moved the second spacewalk to Wednesday to give the crew more time to rest and prepare."

Where Do We Go From Here?

As Space Priorities Shift, Orbiting Station Takes On a Central Role, NY Times

"NASA's Moon program, known as Constellation, has been hamstrung. Although pieces of it could survive in bills under consideration in Congress, it remains unclear what rockets NASA is to build, what their destinations would be and how long it would take to get there. Without the space station, NASA's financing of commercial rockets to take crew and cargo there would almost certainly evaporate. And without government financing, companies would be unlikely to invest billions of dollars to pursue a speculative market."

NASA ISS On-Orbit Status 1 August 2010 (early edition)

"After losing one cooling system pump (of two), ISS is currently stable, although thermally on single string (no redundancy). Last night (at 7:48pm EDT) RPC1 (Remote Power Controller 1) in RPCM (RPC Module) S11A_D tripped open, powering off the Loop A ammonia pump of the S1 ETCS (External Thermal Control System), resulting in the loss of one half of the cooling to ISS. This required a number of powerdowns (i.e., turning off selected systems for thermal protection), including redundant power to four CQs (Crew Quarters), three in Node-2, one in Kibo JPM, with both fans in each CQ remaining functional but zero fault-tolerant (crew is still Go for CQ use). Due to loss of heater power, MBS (Mobile Base System), SSRMS (Space Station Remote Manipulator System), and SPDM (Special Purpose Dexterous Manipulator) are currently zero fault-tolerant."

International Space Station in Stable Configuration After Loss of Cooling Loop

"The flight control and management teams today approved a preliminary plan to replace a planned spacewalk Thursday by Expedition 24 crewmembers Doug Wheelock and Tracy Caldwell Dyson with at least two spacewalks to swap out the failed Pump Module that resides on the station's S1 truss. There are two spare Pump Modules on stowage platforms on the station's truss. The replacement module under consideration for replacement resides on External Stowage Platform 2, which is adjacent to the Quest airlock. The crew is being informed that replanning for alternate spacewalk activity is underway."

Keith's note: Of course, YouTube has the solution to this problem ...
