Description

The LOLA instrument is a payload onboard the Lunar Reconnaissance Orbiter spacecraft that launched to the Moon on 19 June 2009. Using five laser beams that illuminate the lunar surface (created from a single laser beam passing through a diffractive optical system), LOLA turns the reflected beams into data about the Moon. These data can include findings, for example, about the moon’s surface topography, its roughness, slope and reflectance, but also, primarily, provide vital information for a global geodetic grid for the Moon.

Additional Information

  • Recent LOLA data (2010):

    Images above show just two views from recent LOLA research by James Head (et al) who carried out a global census of 5185 craters greater than or equal to 20 kilometres in size. Colours in Green represent the global ‘mean’ elevation value, Blue is below this value, while Yellow is above. Note, how the basin regions (dark regions) show less craters in the range, while those in the highland regions are much higher. Head’s research points to the fact that there were two populations of impactors in the early solar system history, and that the transition occurred near the time of the Orientale Basin event - around the Late Imbrium period (~ 3.85 to 3.75 bn years). - JohnMoore2 JohnMoore2

  • LOLA’s laser pulses can be upto 140/sec working at approximately ±10 cm range measurements at 28 Hz.
  • Principal investigators: David Smith, Maria Zuber.
  • LOLA data are available to the public through the periodic releases of LRO datasets on NASA's PDS, and also sometimes a bit in advance on the MIT site.
