• First American to orbit Earth (1962). Later became a U.S. Senator. Returned to space at age 77 aboard the Space Shuttle — oldest person ever in orbit. A national hero during the Space Race. Instrumental in early NASA prestige. — John Glenn
• First American in space (1961). Later walked on the Moon. Famous for hitting golf balls on the lunar surface. Grounded for years due to an inner ear disorder before returning. One of the original “Mercury Seven.” — Alan Shepard
• First American woman in space (1983). A physicist selected in NASA’s first astronaut class to include women. Faced intense media scrutiny. Later founded an organization promoting STEM education. A major milestone for women in spaceflight. — Sally Ride

• First African American woman in space (1992). A physician and engineer. Later appeared on Star Trek. Advocate for science education. Broke major racial and gender barriers. — Mae Jemison
• Commander of Apollo 13 during its near-disaster. Famously associated with “Houston, we’ve had a problem.” One of only three people to fly to the Moon twice. Never landed on it. His mission became a major film. — Jim Lovell
• Second American in space. First person to fly twice in space. Died in the Apollo 1 launch pad fire. A central figure in NASA’s early development. Helped shape crewed spaceflight protocols. — Gus Grissom
• First human to conduct a spacewalk (1965). Nearly died when his suit ballooned in vacuum. Later commanded the Apollo-Soyuz Test Project. A skilled artist who painted space scenes. Key figure in U.S.–Soviet cooperation. — Alexei Leonov
• First Canadian ISS commander. Became a global sensation for recording “Space Oddity” in orbit. Helped popularize space exploration via social media. Performed multiple spacewalks. One of the most recognizable modern astronauts. — Chris Hadfield
• Holds U.S. record for cumulative time in space (695 days). First female ISS commander. Performed 10 spacewalks. A biochemist by training. One of NASA’s most experienced astronauts. — Peggy Whitson
• Selected as the first “Teacher in Space.” Died in the Challenger disaster. Inspired millions of students. Symbol of both optimism and tragedy in NASA history. Schools nationwide are named after her. — Christa McAuliffe

• Spent nearly a year aboard the ISS. Twin brother of astronaut Mark Kelly. Participated in the NASA Twins Study. Helped study long-duration spaceflight effects. Key for Mars planning research. — Scott Kelly
• A U.S. Navy combat pilot before joining NASA, he flew four Space Shuttle missions. He commanded STS-134, the final flight of Space Shuttle Endeavour. He is the identical twin brother of astronaut Scott Kelly, making them one of the most famous sibling pairs in space history.

• Took the famous “Earthrise” photograph. That image became one of the most influential photos ever taken. Inspired the environmental movement. Flew the first human mission beyond Earth orbit. — William Anders
• First animal to orbit Earth. Did not survive the mission. Her flight proved life could endure launch stresses. Became a symbol of early space experimentation. Remains controversial in animal ethics discussions. — Laika
• Seventh person to walk on the Moon. Conducted the famous hammer-and-feather gravity experiment. Commanded the first mission to use the Lunar Roving Vehicle. Helped prove Galileo’s theory in vacuum. — David Scott
