  2. 6. NASA's project to land humans on the moon in the 1960s and early 1970s
  3. 8. he lander spacecraft that was flown between lunar orbit and the Moon's surface during the U.S. Apollo program
  4. 9. instrument designed to detect and resolve X-rays from sources outside Earth's atmosphere that must be carried to high altitudes by rockets or balloons or placed in orbit outside the atmosphere
  5. 12. a series of competitive technology demonstrations between the United States and the Soviet Union, aiming to show superiority in spaceflight
  6. 13. the difference in the elapsed time as measured by two clocks
  7. 14. a technique that removes the atmospheric disturbance and allows a telescope to achieve diffraction-limited imaging from the ground
  8. 16. a partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration as part of the Space Shuttle program
  9. 18. a telescope that uses lenses to gather and focus light
