...area for sleeping and bathing. Meals will be passed into the van, through an air lock and prepared in a microwave oven in the galley. Air pressure inside the van will be lower than it is outside; if a leak occurs, the "negative" pressure will cause outside air to flow in, preventing organisms from escaping...
...mission proved to be completely successful, it was much too soon to assess its true significance. Historian James MacGregor Burns was not impressed. "It's a very proud and fine day for all Americans," he said, "but it's an event apart from the main flow of history." Stanford Physicist Robert Hofstadter, a Nobel prizewinner, disagreed: "In a thousand years there will be few things remembered, but this will be one of them...
...digging and filling for Marghera's deep-water tanker canals and protective dikes have not only helped erode the island's underpinnings, but also seem to have unsettled the natural ebb and flow of the tidal waters. In the past, flooding was a rarity in Venice. But now it has become almost a regular occurrence, as winds and new tidal currents trap an overflow of water behind the lagoon's three egresses. Along the canals, water has seeped through foundations to crack and moisten plaster walls -some of them holding priceless paintings. The frescoes by Paolo Veronese...
Other scientific benefits will flow immediately from the instruments that the astronauts will leave behind on the moon. As soon as Astronaut Aldrin sets up a seismometer on the lunar surface, for example, a command radioed from earth will activate it by releasing four suspended weights. In the future, whenever a quake or a meteor disturbs the lunar surface, the seismometer's frame will vibrate, while the suspended weights remain immobile. The seismometer, sensing the relative motion between the frame and the weights, will express it as digital data and transmit it to earth. The instrument is so sensitive that...
...vacuum chambers in which the specimens remain while technicians handle them through insulated "glove ports" or by remote-controlled mechanical arms; and 2) an air-conditioning system that maintains lower air pressure within the LRL than outside so that, if there is a break in the system, air would flow in, keeping lunar matter from leaking...
