| | Science Question of the Week - Is any of the scientific equipment left on the Moon by the Apollo astronauts still in use? - April 25, 2003 |
 | | An ongoing program, called APOLLO (the Apache Point Observatory Lunar Laser-ranging Operation), hopes to reduce the measurement of the lunar distance to 1 mm, along with carrying out more experiments on the properties of gravity. |
 | | Apollo 11, 14, and 15 each carried an experiment called the Laser Ranging RetroReflector (LRRR), consisting of an array of corner cube reflectors. |
 | | Although the Apollo astronauts left the Moon for the final time in 1972, they left behind an array of equipment, including the bases of the Lunar Landers, the Lunar Rovers, a variety of scientific equipment, and at least one golf ball. |
