Story summary
  • Lawrence Livermore National Laboratory (LLNL) researchers developed a method to model one million orbits in cislunar space, in a six-year effort.
  • The computation completed in three days on LLNL's supercomputers.
  • About half of the modeled orbits remained stable for at least one year.
  • Nearly 10 percent remained stable for the entire six-year period.
  • The findings could help manage satellite traffic as countries launch satellites without global coordination.
