David Scott

Scott made his first flight into space as pilot of the Gemini 8 mission, along with Neil Armstrong, in March 1966, spending just under eleven hours in low Earth orbit. Scott then spent ten days in orbit as Command Module Pilot aboard Apollo 9, his second spaceflight, along with Commander James McDivitt and Lunar Module Pilot Rusty Schweickart. During this mission, Scott became the last American to fly solo in Earth orbit (not counting subsequent untethered EVAs). Scott made his third and final flight into space as commander of the Apollo 15 mission, the fourth human lunar landing, becoming the seventh person to walk on the Moon and the first person to drive on the Moon.
