NASA . . . IT'S A SMALL WORLD

The National Aeronautics and Space Administration will lay off more than 10 percent of its work force by the year 2000. As part of President Clinton's promise to lop $76 billion off the federal budget over the next five years, NASA said yesterday, the agency will have to cut at least 2,500 civil service jobs from its payroll. "NASA will be small and NASA will be different," agency head Daniel Goldin told employees. "We will have fewer people doing more complex work."
