The NASA Aura spacecraft was successfully launched on July 15, 2004 from Vandenberg Airforce Base in California. Flying in the “A-Train” constellation with other spacecraft, Aura collects measurements of ozone, aerosols and key gases throughout the atmosphere using technologically innovative space instrumentation.
The spacecraft has four instruments, each making their own observations:
- High Resolution Dynamics Limb Sounder
- Microwave Limb Sounder
- Ozone Monitoring Instrument
- Tropospheric Emissions Spectrometer
Scientists use the data collected from Aura’s instruments to gain insights into the chemistry of Earth’s atmosphere.
