At 82, NASA pioneer Sue Finley still reaching for the stars

Sue Finley began work at the Jet Propulsion Laboratory as the US prepared to launch its first satellite into orbit in 1958, racing to match the Soviet Union, which had accomplished the feat months earlier.

Now 82, she is one of NASA’s longest-serving women, starting out as one of its “human computers,” whose critical yet long-hidden contributions to the space program, including the Apollo missions to the Moon, are finally being recognized.
