Power Shortage. As Conrad and his crew ended their second week in space, those chances seemed dim indeed. Skylab's power shortage-which resulted from the jamming of one solar panel and the loss of another during launch, when the orbital workshop's meteoroid and thermal shielding ripped off-had suddenly been compounded by a severe new problem. Two of Skylab's 18 storage batteries had failed...
Until the failure, it had seemed that the astronauts had triumphed over almost insurmountable difficulties. Finally docking with Skylab after five attempts, they had struggled for three hours in 125° temperatures to erect an umbrella-like sunshade over the area where Skylab had lost its micrometeoroid and thermal shielding. The makeshift solution worked. Within a few days, temperatures in the workshop dropped to the low 80s and the astronauts, who had been spending most of their time aboard the Apollo command module, could take up residence in Skylab...
...cylinder will not add more than 10% to the basic cost of the 65-h.p. engine. Moreover, they point out that the engine does not require special servicing or changes of material to maintain low emission. By contrast, U.S. and other foreign engines will need expensive catalytic converters or thermal reactors to meet 1975 emission standards. The catalytic converters can easily be fouled, have tended to break down in tests and, in any case, must be periodically replaced...
...first manned solar observatory in earth orbit and contains eight separate telescopes for different types of astronomical observations; and 4) the Airlock Module, which serves as a pressurization chamber for sorties out into space and is the nerve center for the entire station; it is equipped with thermal and electrical controls and extensive communications gear, including a teleprinter to receive updated flight plans from Mission Control in Houston...
Second, we feel that global thermal pollution, not crowding, will probably impose the first total limit to economic growth on earth. Many people estimate that the thermal pollution required to bring earth's present population up to America's present standard of living, without depending on nonrenewable resources, will be enough to melt the polar icecaps and drown most of the people and almost all of the farms in the world. (Jay Forrester's group, for example, recommends that underdeveloped countries slow down their growth now, because it will be impossible on earth to close the gap between them...
