Valentina Tereshkova, who became the first woman in space in 1963, is seen on this Soviet postage stamp.
Dr. Shannon Lucid was the first woman to hold an international record for the most flight hours in orbit by any non-Russian, and until June 2007 she also held the record for the most flight hours in orbit by any woman in the world. NASA
Jerrie Cobb, a well known female pilot in the 1950s, tests a Gimbal Rig in the Altitude Wind Tunnel in April 1960. Jerrie Cobb was the first female to pass all three phases of the Mercury Astronaut Program but NASA rules stipulated that only military test pilots could become astronauts and there were no female military test pilots. Jerrie completed this astounding feat in 1961. NASA

Exuberant and thrilled to be at the Kennedy Space Center, seven women who once aspired to fly into space stand outside Launch Pad 39B near the Space Shuttle Discovery, poised for liftoff on the first flight of 1995. They are members of the First Lady Astronaut Trainees, a group of women who trained to become astronauts for America's first human spaceflight program back in the early 1960s. Although this FLATs effort was never an official NASA program, their commitment helped pave the way for the milestone Eileen Collins set: becoming the first female Shuttle pilot. NASA

Now, NASA and the Navy are training again for the first such recovery in a generation.
