Target entity: Lunar Laser Ranging experiments
Context triple: [de Sitter effect, testedBy, Lunar Laser Ranging experiments]
  • A. Satellite Laser Ranging
    Satellite Laser Ranging is a geodetic technique that uses ground-based lasers to precisely measure the distance to satellites equipped with retroreflectors, enabling highly accurate determination of Earth’s shape, rotation, and reference frames.
  • B. International Laser Ranging Service
    The International Laser Ranging Service is an international organization that coordinates and supports satellite and lunar laser ranging activities to improve global reference frames, Earth science, and geodetic research.
  • C. Lunar Seismic Profiling Experiment
    The Lunar Seismic Profiling Experiment was a geophysical investigation deployed during Apollo 17 to study the Moon’s shallow subsurface structure by recording seismic waves from controlled explosive charges.
  • D. Copernican System of lunar stratigraphy
    The Copernican System of lunar stratigraphy is the youngest major geologic time division on the Moon, characterized by relatively fresh impact craters with bright ray systems and minimal space weathering.
  • E. Gravity Probe B experiment
    Gravity Probe B experiment was a NASA-led satellite mission designed to precisely measure how Earth's gravity warps space and time, providing a high-accuracy test of key predictions of Einstein's general relativity.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
