Aura

Aura is NASA's atmospheric-chemistry mission measuring ozone, trace gases and aerosols. Its Microwave Limb Sounder and Ozone Monitoring Instrument support research on ozone recovery, air quality and atmospheric change. Orbit-maintenance maneuvers ended in 2023, allowing altitude and local observation time to drift; instrument teams account for these changes in retrievals. Daily yaw maneuvers began in July 2026 to restore OMI solar-aperture alignment for calibration. NASA's September 2026 assessment reports good spacecraft and instrument health; projected power limitations around mid-2028 are estimates rather than a confirmed mission end date.

Destination
Near-polar, sun-synchronous Earth orbit at approximately 705 km altitude and 98.2° inclination for measuring ozone, aerosols, and key trace gases throughout Earth’s atmosphere
Launch Site
Outcome
Launched July 15, 2004, Aura provides atmospheric-composition observations that improve understanding of ozone, air quality and climate processes.
