  • Inclination: 98.5 degrees
  • Period: 99 minutes (16 orbits per day)
  • Equatorial crossing: 10:30 a.m., descending mode

Terra Status:

  • Operating instruments: ASTER, CERES, MODIS, MISR, and MOPITT are operating well.  ASTER Short Wave Infrared (SWIR) data is unavailable.
  • Current life expectancy: Terra  has far exceeded its design life and has a strong chance of operating successfully into the early 2020s.
  • Current systems issues: None.
  • Processed Terra data are available through several NASA data centers.
