Who was the first American woman in space?

• A. Valentina Tereshkova
• B. Mae Jemison
• C. Sunita Williams
• D. Sally Ride

Answer: (D)

You're being tested on remembering a notable milestone in space exploration. The key idea is identifying who broke the barrier as the first American woman to travel into space.

Sally Ride earned that distinction when she flew on the Space Shuttle Challenger on mission STS-7 in 1983, becoming the first American woman in space. It’s easy to confuse this with the very first woman in space, who happened to be Valentina Tereshkova in 1963, but she represented the Soviet program. Mae Jemison later became the first African American woman in space in 1992, and Sunita Williams is also a prominent NASA astronaut, but neither preceded Ride as the first American woman in space.
