During her inaugural mission in 1985, Cleave made history as the 10th woman to journey into space aboard NASA's Space Shuttle Atlantis. Her second flight, STS-30, took place in 1989 on the same shuttle after NASA had resumed all-male crews for three missions following the Challenger explosion. With a total of over 10 days spent in orbit, Cleave made significant contributions during her time in space.

In 2000, she relocated to Washington, DC to begin her work at NASAs headquarters. She made history by becoming the first woman to serve as the associate administrator for NASAs Science Mission Directorate, where she oversaw the space agencys research programs. After retiring from NASA in 2007, she focused on volunteer work and inspiring young women to pursue scientific careers, as noted on her bio on the Maryland government's website.
