New Impacts on the Moon: LRO Camera Identifies Recent Craters
Banner says New Impacts on the Moon: LRO Camera Identifies Recent Craters
Black and white image of the moon with marks showing new impacts.
The red squares indicate small (a few meters) changes in the surface over the course of a year.
  • Comparison of images taken by LRO/LROC in the 4 years of operations reveal new craters
  • Repeat images were taken at nearly identical illumination conditions for easy change detection
  • In some cases, clusters of possible new craters are observed, suggesting a swarm of impactors
  • Over 65 new craters have been found thus far in the ~1% of the Moon with repeated NAC images
  • Based on the number of observed new craters, over one year ~180,000 impacts, that could be identified by LROC, are predicted to form
  • These new impacts constrain the rate of small impact flux and provide new insights into the modification and erosion of the lunar surface
