Which NASA astronaut served as Mission Specialist on STS-129 and spent over 259 hours in space?

• A. Neil Armstrong
• B. Sally Ride
• C. Robert L. Satcher Jr.
• D. Mae Jemison

Answer: (C)

This question tests your ability to connect an astronaut’s specific role on a shuttle mission with their total time in space. Robert L. Satcher Jr. is the astronaut who fits both parts: he served as a Mission Specialist on the Space Shuttle mission STS-129 and he spent more than 259 hours in space. Mission Specialists are crew members assigned specialized duties—such as conducting experiments, assisting with spacewalks, and handling operations on the International Space Station—during a shuttle flight. Among the listed astronauts, he is the one known to have that particular assignment on STS-129 and to have accumulated that amount of time in space. The others were on different missions or do not match the specific mission and time criteria.
